Documentation

A large part of the scripting documentation has been improved and an online version with searching capability can be found at https://amxmodx.org/api/.

Gamedata

As stated in the Release Notes, we have now gamedata files to avoid to hard code data related to the game or engine. Such files located in the amxmodx/data/gamedata/ directory.

Gamedata files shipped with AMX Mod X can and will be updated at any time, therefore it is strongly discouraged to edit them manually.
To make custom gamedata changes, please use the custom folder under the gamedata directory. All files under this directory are parsed (in an undefined order) after the main files are loaded. They will never be overwritten.

The files structure is currently arranged this way:

├─ common.games │ ├─ entities.games │ │ └─ $mod │ │ ├─ offsets-$class.txt │ │ ├─ ... │ ├─ gamerules.games │ │ └─ $mod │ │ ├─ offsets-$class.txt │ │ ├─ ... │ ├─ hostages.games │ │ └─ $mod │ │ ├─ offsets-$class.txt │ │ ├─ ... │ ├─ others.games │ │ └─ $mod │ │ ├─ offsets-$class.txt │ │ ├─ ... │ ├─ functions.engine.txt │ ├─ globalvars.engine.txt │ └─ master.games.txt ├─ modules.games │ ├─ master.games.txt │ └─ game.cstrike.txt

The main directories are:

• common.games contains the shared data.
• modules.games contains the data per module.

In those directories, you will find:

• master.games.txt which references all the files to be loaded by the core/modules.

Inside common.games directory:

• entities.games, entities.games, entities.games and others.games directories contains the $class member's offset per-$mod. Related to gamerules object but also player, hostage, item and weapons entities.
• functions.engine.txt contains the symbols/signatures of functions in the engine.
• globalvars.engine.txt contains the symbols/signatures of global variables in the engine.

Inside modules.games directory:

• game.cstrike.txt contains CS-specific data such as the symbol/signatures of functions and others static datas.

Note:More details about the file format can be found in the Quick Guide in #Game_Config_Parser.

Compiler

Along a bunch of fixed issues, there are some improvements/features worth to be noted.

Emscripten support

The AMX Mod X Compiler can now be compiled with Emscripten allowing it to run inside of a web browser.

A good example is Spider, a web-based, entirely client-side, editor and compiler for [Source]Pawn development (by asherkin).

Increased Limits

Name/function and input line maximum length (in characters) have been increased.

Description	Old value	New value
Name/Function	31	63
Input Line	511	4095

Predefined Constants

Global	Description
__BINARY__	Name of the compiled plugin. Example: admin.amxx
__FILE__	Name of the source plugin. Custom includes is supported. Example: admin.sma, myinclude/myfile.inc
__LINE__	Current line from the plugin's source code.

Note:Values are populated at compile time.

Pragma

A new #pragma deprecated has been added to tell the compiler that this specific native/stock is deprecated.
This will issue a warning upon the compilation.

Example:⇅

#pragma deprecated  Some comment here.
native foo();

At compilation:

[...] warning 233: symbol "foo" is marked as deprecated: Some comment here.

String Literal Contatenation

This basically allows you to concatenate literal strings and stringizing a parameter in macro substitution only (so possible breakage is very limited).

Description	Symbol
To concatenate	+
To Stringize	#

Example:⇅

#define PROJECT_AUTHOR    "AMX Mod X"
#define PROJECT_COPYRIGHT "Copyright (C) 2017  " + PROJECT_AUTHOR
 
#define VERSION_MAJOR      "1"
#define VERSION_MINOR      "9"
#define VERSION_RELEASE    "0"
#define VERSION            VERSION_MAJOR + "." + VERSION_MINOR + "." + VERSION_RELEASE
 
#define log(%1)  "logging: " + #%1 + "\n"
 
foo()
{
    server_print(log(hello));
}

Internal Core Changes

String Buffer

The buffer size AMX Mod X uses internally to retrieve strings has been increased from 3k to 16k.

Note:A MAX_STRING_LENGTH define has been added in amxconst.inc.

Note:By default plugins don't have enough memory available to allocate an array of this size.
You probably should not use this define to actually declare a buffer unless you absolutely have to.
Look at #pragma dynamic to increase a plugins available memory.

New Core APIs

Automatic Config File

This provides a system for plugins to automatically generate config files with plugin's cvars which get executed on load.
This is done via the AutoExecConfig native.

Once all configuration files are executed, OnConfigsExecuted is called. This forward will always be called, even if your plugin had no configs or if it was loaded late.

Native

Description

AutoExecConfig

⇅ Specifies that the given config file should be executed after plugin load. /** * Specifies that the given config file should be executed after plugin load. * * @note OnConfigsExecuted() will not be called until the config file has executed, * but it will be called if the execution fails. * @note The name parameter should not contain dots, otherwise file will not be executed. * * @param autoCreate If true, and the config file does not exist, such a config * file will be automatically created and populated with * information from the plugin's registered cvars. * @param name Name of the config file, excluding the .cfg extension. * If empty, <plugin.filename.cfg> is assumed. * @param folder Folder under plugins/ to use. * * @noreturn */ native AutoExecConfig(bool:autoCreate = true, const name[] = "", const folder[] = "");

Forward	Description
OnConfigsExecuted	⇅ Called when the map has loaded, and all configs are done executing. /** * Called when the map has loaded, and all configs are done executing. * This includes servercfgfile (server.cfg), amxx.cfg, plugin's config, and * per-map config. * * @note This is best place to initialize plugin functions which are based on cvar data. * @note This will always be called once and only once per map. It will be * called few seconds after plugin_cfg(). * * @noreturn */ forward OnConfigsExecuted();
OnAutoConfigsBuffered	⇅ Called when the map has loaded, right after plugin_cfg but any time before OnConfigsExecuted. /** * Called when the map has loaded, right after plugin_cfg() but any time * before OnConfigsExecuted. It's called after amxx.cfg and all * AutoExecConfig() exec commands have been added to the server command buffer. * * @note This will always be called once and only once per map. * * @noreturn */ forward OnAutoConfigsBuffered();

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    register_plugin("Hat", "User", "1.0");
 
    create_cvar("mysqlk_database", "", .description = "MySQL database");
    create_cvar("mysqlk_host", "localhost", .description = "MySQL host, use this to configure various^nthings for your server.");
 
    AutoExecConfig();
}

That would export a config file that looks like this:

// This file was auto-generated by AMX Mod X (v1.9)
// Cvars for plugin "Hat" by "User" (hat.amxx, v1.0)
 
 
// MySQL database
// -
// Default: ""
mysqlk_database ""
 
// MySQL host, use this to configure various
// things for your server.
// -
// Default: "localhost"
mysqlk_host "localhost"

DataPack

This offers you a way to dynamically store and move around various types of data.

Datapacks provide a way to store and move around arbitrary amounts (and types) of data in AMX Mox X, available from datapack.inc.
Data is packed into a single cell value - the DataPack handle. This handle can be passed around more easily, can be returned by functions and can simulate advanced concepts like string consummation.

Native	Description
Creating & Disposing
CreateDataPack	⇅ Creates a new datapack. /** * Creates a new datapack. * * @return New datapack handle, which must be freed via DestroyDataPack(). */ native DataPack:CreateDataPack();
DestroyDataPack	⇅ Destroys the datapack and frees its memory. /** * Destroys the datapack and frees its memory. * * @param pack Datapack handle * * @return True if disposed, false otherwise */ native DestroyDataPack(&DataPack:pack);
Resetting
ResetPack	⇅ Resets the datapack read/write position to the start. /** * Resets the datapack read/write position to the start. * * @param pack Datapack handle * @param clear If true, clears the contained data * * @noreturn * @error If an invalid handle is provided, an error will be thrown. */ native ResetPack(DataPack:pack, bool:clear = false);
Writing data
WritePackCell	⇅ Packs a cell value into a datapack. /** * Packs a cell value into a datapack. * * @param pack Datapack handle * @param cell Cell value to pack * * @noreturn * @error If an invalid handle is provided, an error will be thrown. */ native WritePackCell(DataPack:pack, any:cell);
WritePackFloat	⇅ Packs a float value into a datapack. /** * Packs a float value into a datapack. * * @param pack Datapack handle * @param val Float value to pack * * @noreturn * @error If an invalid handle is provided, an error will be thrown. */ native WritePackFloat(DataPack:pack, Float:val);
WritePackString	⇅ Packs a string into a datapack. /** * Packs a string into a datapack. * * @param pack Datapack handle * @param str String to pack * * @return Length of copied string * @error If an invalid handle is provided, an error will be thrown. */ native WritePackString(DataPack:pack, const str[]);
Reading data
ReadPackCell	⇅ Reads a cell from a Datapack. /** * Reads a cell from a Datapack. * * @param pack Datapack handle * * @return Cell value * @error If an invalid handle is provided, or not enough data is left * in the datapack, an error will be thrown. */ native any:ReadPackCell(DataPack:pack);
ReadPackFloat	⇅ Reads a float from a Datapack. /** * Reads a float from a datapack. * * @param pack Datapack handle * * @return Float value * @error If an invalid handle is provided, or not enough data is left * in the datapack, an error will be thrown. */ native Float:ReadPackFloat(DataPack:pack);
ReadPackString	⇅ Reads a string from a Datapack. /** * Reads a string from a Datapack. * * @param pack Datapack handle * @param buffer Buffer to copy string to * @param maxlen Maximum size of buffer * * @return Number of cells written to buffer * @error If an invalid handle is provided, or not enough data is left * in the datapack, an error will be thrown. */ native ReadPackString(DataPack:pack, buffer[], maxlen);
Managing position
GetPackPosition	⇅ Returns the datapack read/write position. /** * Returns the datapack read/write position. * * @param pack Datapack handle * * @return Position in the datapack, only usable with calls to SetPackPosition * @error If an invalid handle is provided, an error will be thrown. */ native DataPackPos:GetPackPosition(DataPack:pack);
SetPackPosition	⇅ Sets the datapack read/write position. /** * Sets the datapack read/write position. * * @note This should only ever be used with (known to be valid) positions * returned by GetPackPosition(). It is not possible for plugins to safely * compute datapack positions. * * @param pack Datapack handle * @param position New position to set * * @noreturn * @error If an invalid handle is provided, or the new position is * out of datapack bounds, an error will be thrown. */ native SetPackPosition(DataPack:pack, DataPackPos:position);

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    // Creating
    new const DataPack:pack = CreateDataPack();
 
    // Writing
    WritePackCell(pack, refCell);
    WritePackFloat(pack, refFloat);
    WritePackString(pack, refString);
 
    // Reset before reading
    ResetPack(pack);
    server_print("Datapack is readable: %s", !IsPackEnded(pack) ? "yes" : "no");
 
    // Reading
    new cellValue = ReadPackCell(pack);
    new Float:floatValue = ReadPackFloat(pack);
    new buffer[32];
    ReadPackString(pack, buffer, charsmax(buffer));
    server_print("cellValue = %d, floatValue = %f, buffer = %s", cellValue, floatValue, buffer)
    server_print("Datapack is no more readable: %s", IsPackEnded(pack) ? "yes" : "no");
 
    // Clear all data
    ResetPack(pack, .clear = true);
    server_print("Datapack is empty: %s", IsPackEnded(pack) ? "yes" : "no");
 
    // Disposing
    DestroyDataPack(pack);
}

Game Config Parser

Now we have gamedata files, we strongly encourage any plugins which hardcode static game datas to use the following API.

Native	Description
Loading & Closing file
LoadGameConfigFile	⇅ Loads a game config file. /** * Loads a game config file. * * @note The file path must be relative to the 'gamedata' folder under the data folder * and the extension should be omitted. * * @param file File to load * * @return A handle to the game config file */ native GameConfig:LoadGameConfigFile(const file[]);
CloseGameConfigFile	⇅ Destroys a game config and frees its memory. /** * Destroys a game config and frees its memory. * * @note The function automatically sets the variable passed to it to 0 to aid * in preventing accidental usage after destroy. * * @param handle Game config handle * * @return 1 on success, 0 if an invalid handle was passed in */ native CloseGameConfigFile(&GameConfig:handle);
Getting value
GameConfGetOffset	⇅ Returns an offset value. /** * * * @param handle Game config handle * @param key Key to retrieve from the offset section * * @return An offset, or -1 on failure * @error Invalid game config handle */ native GameConfGetOffset(GameConfig:handle, const key[]);
GameConfGetClassOffset	⇅ Returns an offset value given a classname. /** * Returns an offset value given a classname. * * @param handle Game config handle * @param classname Class name to match from the offset section * @param key Key to retrieve from the offset section * * @return An offset, or -1 on failure * @error Invalid game config handle */ native GameConfGetClassOffset(GameConfig:handle, const classname[], const key[]);
GameConfGetKeyValue	⇅ Gets the value of a key from the "Keys" section. /** * Gets the value of a key from the "Keys" section. * * @param handle Game config handle * @param key Key to retrieve from the Keys section * @param buffer Destination string buffer * @param maxlen Maximum length of output string buffer * * @return True if key existed, false otherwise * @error Invalid game config handle */ native bool:GameConfGetKeyValue(GameConfig:handle, const key[], buffer[], maxlen);
GameConfGetAddress	⇅ Finds an address calculation in a GameConfig file. /** * Finds an address calculation in a GameConfig file. * * @param handle Game config handle * @param name Name of the property to find * * @return An address calculated on success, otherwise 0 on failure. * @error Invalid game config handle */ native GameConfGetAddress(GameConfig:handle, const name[]);

Quick guide:⇅

Config location

Any default and new gamedata files must be located in /amxmodx/data/gamedata/ directory.
You can create your own directories inside as well.

Filename format

The file name must end with .txt extension, e.g. myfile.txt

Loading a specific file

The right way to load a file is to provide the filename without .txt extension.
E.g. LoadGameConfigFile("myfile") will try to load /data/gamedata/myfile.txt.

Loading multiple files

You are able to load several at once via a master file, named master.game.txt.
A master file is basically a way to tell the parser to load any files listed inside and nothing else.
You can also specify whether a file should be loaded depending the mod name (such as cstrike) or engine (dedicated server: engine_ds or listen server: engine_ls).

For example:

├─ gamedata
│  └─ myfolder
│	  ├─ myfile1.txt
│	  ├─ myfile2.txt
│	  ├─ myfile3.txt
│	  └─ master.game.txt

master.game.txt:

"Game Master"           // Must start with this.
{
    "myfile1.txt"       // No option, will be loaded all the time
    {
    }
 
    "myfile2.txt"       // Will be loaded for both servers
    {
        "engine"  "engine_ds"
        "engine"  "engine_ls"
    }
 
    "myfile3.txt"       // Will be loaded only if the mod is Counter-Strike.
    {
        "game"  "cstrike"
    }
}

Then to load, you only need to provide your directory, e.g. LoadGameConfigFile("myfolder").
This will looks at the /gamedata/myfolder/master.game.txt file and will load the listed files from there.

Config file format

The config file has a specific format as well. This must to start with:

"Games"
{
 
}

Then, you need to tell on what game the date will be loaded.
There are different values:

• "<game name>", such as cstrike
• "*" or "#default" to match any game

"Games"
{
    "cstrike"
    {
        // Counter-Strike only
    }
 
    "#default"
    {
        // Any game
        // Note you can create multiple game blocks.
    }
}

If you need to create a block which inherit multiple games or engine, you can achieve it with #supported key.

"Games"
{
    "#default"	// Must start with this
    {
        "#supported"
        {
            "game"   "cstrike"
            "game"   "czero"
 
            "engine"  "engine_ds"  // you can specify the engine as well.
         }
 
        // Data
    }
}

Data Type

There are 5 different types of datas that you are allowed to store:

• Signature:

Retrieves an address from either a symbol or bytes. E.g. @g_pGameRules or \xDC\x2A\x2A\x2A\x2A\x2A\xA1\x2A\x2A\x2A\x2A\x56

Symbol must start with @.

For use with GameConfGetAddress native.

• Address:

Reads a value from a given address (usually from signature reference)

For use with GameConfGetAddress native.

• Offset:

A platform-dependent value (windows, linux or mac)

For use with GameConfGetOffset native.

• Class Offset:

Same as Offset but can be grouped into a classname

For use with GameConfGetClassOffset native.

• Keyvalue:

simple key associated to a value.

For use with GameConfGetKeyValue native.

"Games"
{
    "#default"
    {
        "Signatures"
        {
            "SV_DropClient"
            {
                "library"   "engine" // This can be either "server" (mod), "engine_ds" (dedicated server) or "engine_ls' (listen server)
                "windows"   "\x55\x8B\x2A\x81\x2A\x2A\x2A\x2A\x2A\x8B\x2A\x2A\x53\x56\x8D"
                "linux"     "@SV_DropClient"
                "mac"       "@SV_DropClient" // Note: A symbol must start always with '@'
            }
 
            "g_pGameRules"
            {
                "library"   "server"

                "windows"
                {
                    "read"   "2"
                }
 
                "read"  "0"
            }

        }
    }
}

Hasher

Supports several new hash types: CRC32, MD5, SHA*, Keccak*.

Note:The following API deprecates md5 and md5_file natives.

Native	Description
hash_string	⇅ Generates a hash value (message digest). /** * Generates a hash value (message digest) * * @param string String to be hashed. * @param type Type of selected hashing algorithm. See Hash_* constants in amxconst.inc file. * @param output Output string to store hash in. * @param outputSize The maximum size of the output string to store hash in. * * @return Number of written bytes. */ native hash_string(const string[], const HashType:type, output[], const outputSize);
hash_file	⇅ Generates a hash value using the contents of a given file. /** * Generates a hash value using the contents of a given file * * @param fileName Path of file to be hashed. * @param type Type of selected hashing algorithm. See Hash_* constants in amxconst.inc file. * @param output Output string to store hash in. * @param outputSize The maximum size of the output string to store hash in. * * @return Number of written bytes. * @error If the file couldn't be opened, an error is thrown. */ native hash_file(const fileName[], const HashType:type, output[], const outputSize);

The available HashType constants are:

• Hash_Crc32
• Hash_Md5
• Hash_Sha1
• Hash_Sha256
• Hash_Sha3_224
• Hash_Sha3_256
• Hash_Sha3_384
• Hash_Sha3_512
• Hash_Keccak_224
• Hash_Keccak_256
• Hash_Keccak_384
• Hash_Keccak_512

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    new hash1[32];
    new const message[] = "Hello World!";
    new const length = hash_string(message, Hash_Md5, hash1, charsmax(hash1));
 
    server_print("hash1 = %s", hash1);
 
    new hash2[32];
    new const fileName[] = "server.cfg";
    new const length = hash_file(message, Hash_Md5, hash2, charsmax(hash2));
 
    server_print("hash2 = %s", hash2);
}

Stack Structure

A stack is a LIFO (last in, first out) dynamic vector of of items.

Stacks provide only two operations:

• Push, adding an item to the top.
• Pop, removing an item from the top, in reverse-push order.

Note:An example is available in the testsuite directory, see stacktest.sma.

Native	Description
Creating & Destroying
CreateStack	⇅ Creates a stack structure. /** * Creates a stack structure. A stack is a LIFO (last in, first out) vector of * of items. It has O(1) insertion and O(1) removal. * * @note Stacks provide only two operations: Push (adding an item to the top) * and Pop (remove an item from the top, in reverse-push order). * @note The contents of the stack are uniform; i.e. storing a string and then * retrieving it as an integer is NOT the same as str_to_num()! * @note The "blocksize" determines how many cells each stack slot has, it can * not be changed after creation. * * @param blocksize The number of cells each entry in the stack can hold * * @return New stack Handle, which must be freed via DestroyStack() * @error If an invalid blocksize is provided an error will be * thrown. */ native Stack:CreateStack(blocksize = 1);
DestroyStack	⇅ Destroys a stack and frees its memory. /** * Destroys a stack and frees its memory. * * @note The function automatically sets the variable passed to it to 0 to aid * in preventing accidental usage after destroy. * * @param handle Stack to destroy * * @return 1 if the Stack was destroyed, 0 if nothing had to be * destroyed (invalid handle) */ native DestroyStack(&Stack:handle);
Pushing Data
PushStackCell	⇅ Pushes a value onto the end of the stack, adding a new index. /** * Pushes a value onto the end of the stack, adding a new index. * * @note This may safely be used even if the stack has a blocksize greater than * 1. * * @param handle Stack handle * @param value Value to push * * @noreturn * @error If an invalid handle is provided or the resizing * operation runs out of memory, an error will be thrown. */ native PushStackCell(Stack:handle, any:value);

Text Parser INI/SMC

Event-based text parser to read data in an unified way. It supports INI and SMC (similar to VTF) formats.

Note:An example is available in the testsuite directory, see textparse.sma.

SMC Format

Technical format detail:⇅

/**
 * The SMC file format is defined as:
 *    WHITESPACE: 0x20, \n, \t, \r
 *    IDENTIFIER: Any ASCII character EXCLUDING ", {, }, ;, //, / *, or WHITESPACE.
 *    STRING    : Any set of symbols enclosed in quotes.
 *
 *    Note: if a STRING does not have quotes, it is parsed as an IDENTIFIER.
 *
 * Basic syntax is comprised of SECTIONBLOCKs.
 *    A SECTIONBLOCK defined as:
 *
 *    SECTIONNAME
 *    {
 *        OPTION
 *    }
 *
 * OPTION can be repeated any number of times inside a SECTIONBLOCK.
 * A new line will terminate an OPTION, but there can be more than one OPTION per line.
 * OPTION is defined any of:
 *    "KEY"  "VALUE"
 *    SECTIONBLOCK
 *
 * SECTIONNAME, KEY, VALUE, and SINGLEKEY are strings
 * SECTIONNAME cannot have trailing characters if quoted, but the quotes can be optionally removed.
 * If SECTIONNAME is not enclosed in quotes, the entire sectionname string is used (minus surrounding whitespace).
 * If KEY is not enclosed in quotes, the key is terminated at first whitespace.
 * If VALUE is not properly enclosed in quotes, the entire value string is used (minus surrounding whitespace).
 * The VALUE may have inner quotes, but the key string may not.
 *
 * WHITESPACE should be ignored.
 * Comments are text occurring inside the following tokens, and should be stripped
 * unless they are inside literal strings:
 *    ;<TEXT>
 *    //<TEXT>
 *    / *<TEXT> * /
 *
 * Example file below:
 *   "SomeSection"
 *   {
 *	      /**
 *	       * Some comment
 *         */
 *	      "Key"		"value"

Existing core APIs additions

Client

Behavior changes

• The following natives can now be used on connecting players: find_player, get_players and engclient_print (console only).
• set_user_rendering default color and amount are now set to 0 to follow game behavior.

(Dis)connection

Note:The client_disconnect forward is deprecated in favor of client_disconnected.
This will be called in some additional cases that client_disconnect doesn't cover, most notably when a client aborts the connection process.
It is guaranteed to pair with the client_connect forward.

Command

Callback

Native

Description

amxclient_cmd

⇅ Executes a command from the client without actually sending it to the client's DLL. Similar to engclient_cmd with the difference this triggers plugin command hooks. /** * Execute a command from the client without actually sending it to the client's * DLL. This triggers plugin command hooks. * * @note This emulates a client command on the server side, and is an excellent * tool to force a client to do certain actions related to the game. * @note The command has to stand alone in the command parameter, only add * arguments using the designated parameters. * @note Commands emulated using this function will trigger other plugin's * command hooks. For an alternative that doesn't, see engclient_cmd() * * @param index Client index, use 0 to execute from all clients * @param command Client command to execute on * @param arg1 Optional command arguments * @param arg2 Optional command arguments * * @noreturn * @error If a single client is specified and the index is not within * the range of 1 to MaxClients, an error will be thrown. */ native amxclient_cmd(index, const command[], const arg1[] = "", const arg2[] = "");

Arguments conversion

New natives to retrieve a command's argument directly as an integer or float instead of as a string (read_argv()).

Native	Description
read_argv_int	⇅ Retrieves argument of client command as integer value. /** * Retrieves argument of client command as integer value. * * @note Should only be used inside of the client_command() forward. * * @param id Argument index starting from 1 * * @return Integer value */ native read_argv_int(id);
read_argv_float	⇅ Retrieves argument of client command as float value. /** * Retrieves argument of client command as float value. * * @note Should only be used inside of the client_command() forward. * * @param id Argument index starting from 1 * * @return Float value */ native Float:read_argv_float(id);

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    register_clcmd("set_level", "@OnSetLevel", .info = "<value> - Sets a custom level");
}
 
@OnSetLevel(const client, const command_level, const command_id)
{
    new const value = read_argv_int(1);
}

Translatable description

In order to encourage the translations of command's description, a new parameter is available.
This is useful for use with the amx_help client command for example.

Example:⇅

[en]
MY_KEY = Hello world!

#include <amxmodx>
 
public plugin_init()
{
    register_clcmd("my_command", "OnMyCommand", ADMIN_CFG, "MY_KEY", .info_ml = true);
}

Cvar

In order to manage cvars more easily, several new cvar features have been added.

Note:A cvar managed at least once is now cached internally, for faster lookup, that's it.

Note:The cvar API is now moved to its own cvars.inc include file.

Hooking

You can now hook when a cvar value has changed. This allows plugins to react to cases where other plugins or clients change a cvar's value.

Native	Description
hook_cvar_change	⇅ To create a hook /** * Creates a hook for when a cvar's value is changed. * * @note Changing the cvar value from within this forward can lead to infinite * recursion and should be avoided. * @note The callback will be called in the following manner: * * public cvar_change_callback(pcvar, const old_value[], const new_value[]) * * pcvar - Pointer to cvar that was changed * old_value - Buffer containing the previous value of the cvar * new_value - Buffer containing the new value of the cvar * * The return value is ignored * * @param pcvar Pointer to cvar * @param callback Name of callback function * * @return Callback handle that can be used with * [disable|enable]_cvar_hook * @error If an invalid cvar pointer or callback function is provided, * an error will be thrown. */ native cvarhook:hook_cvar_change(pcvar, const callback[]);
disable_cvar_hook	⇅ To disable a hook /** * Disables a cvar hook, stopping it from being called. * * @note Use the handle returned by hook_cvar_change as the parameter here. * * @param handle Forward to disable * @error If an invalid hook handle is provided, an error will be * thrown. */ native disable_cvar_hook(cvarhook:handle);
enable_cvar_hook	⇅ To enable a hook /** * Enables a cvar hook, restoring it to being called. * * @note Use the handle returned by hook_cvar_change as the parameter here. * * @param handle Forward to enable * @error If an invalid hook handle is provided, an error will be * thrown. */ native enable_cvar_hook(cvarhook:handle);

Example:⇅

#include <amxmodx>
 
new cvarhook:CvarHandle;
 
public plugin_init()
{
    CvarHandle = hook_cvar_change(get_cvar_pointer("mp_timelimit"), "@OnTimelimitChange");
 
    register_concmd("enable_hook" , "@OnConsoleCommand_EnableHook");
    register_concmd("disable_hook", "@OnConsoleCommand_DisableHook");
}
 
@OnTimelimitChange(const pointer, const old_value[], const new_value[])
{
    server_print("mp_timelimit: %s -> %s", old_value, new_value);
}
 
@OnClientCommand_EnableHook()
{
    enable_cvar_hook(CvarHandle);
}
 
@OnClientCommand_DisableHook()
{
    disable_cvar_hook(CvarHandle);
}

Binding

There are situations where you don't need to hook/manage a cvar value and you would wish to not deal with cvar pointers.
You can now bind a cvar's value to a global variable. This means that variable value will be always up to date.

Native	Description
bind_pcvar_num	⇅ To bind an integer /** * Binds a cvar's integer value to a global variable. The variable will then * always contain the current cvar value as it is automatically kept up to date. * * @note The variable *has* to be a global or a static variable. Local variables * created within functions can not be used for technical reasons. * @note Variables can not be bound to multiple cvars. * * @param pcvar Pointer to cvar * @param var Global variable to keep updated * * @noreturn * @error If an invalid cvar pointer or variable is provided, an error * will be thrown. */ native bind_pcvar_num(pcvar, &any:var);
bind_pcvar_float	⇅ To bind a float /** * Binds a cvar's float value to a global variable. The variable will then * always contain the current cvar value as it is automatically kept up to date. * * @note The variable *has* to be a global or a static variable. Local variables * created within functions can not be used for technical reasons. * @note Variables can not be bound to multiple cvars. * * @param pcvar Pointer to cvar * @param var Global variable to keep updated * * @noreturn * @error If an invalid cvar pointer or variable is provided, an error * will be thrown. */ native bind_pcvar_float(pcvar, &Float:var);
bind_pcvar_string	⇅ To bind a string /** * Binds a cvar's string value to a global array. The array will then * always contain the current cvar value as it is automatically kept up to date. * * @note The array *has* to be a global or a static array. Local arrays * created within functions can not be used for technical reasons. * @note Arrays can not be bound to multiple cvars. * * @param pcvar Pointer to cvar * @param var Global array to keep updated * @param varlen Maximum length of string array * * @noreturn * @error If an invalid cvar pointer or variable is provided, an error * will be thrown. */ native bind_pcvar_string(pcvar, any:var[], varlen);

Example:⇅

#include <amxmodx>
 
new CvarTimelimit;
new Float:CvarBuyTime;
new CvarSomething[32];
 
public plugin_init()
{
    bind_pcvar_num(get_cvar_pointer("mp_timelimit"), CvarTimelimit);
    bind_pcvar_float(get_cvar_pointer("mp_buytime"), CvarBuyTime);
    bind_pcvar_string(register_cvar("amx_something", "something"), CvarSomething, charsmax(CvarSomething));
 
    server_print("mp_timelimit  current value: %d", CvarTimelimit);
    server_print("mp_buytime    current value: %f", CvarBuyTime);
    server_print("amx_something current value: %s", CvarSomething);
}

Boundary

Having a better control over a cvar's value, we can enforce the value to be in a defined boundary.

Description	Native
get_pcvar_bounds	⇅ To get a boundary /** * Retrieves the specified value boundary of a cvar. * * @param pcvar Pointer to cvar * @param type Type of boundary to retrieve * @param value Variable to store the specified boundary to * * @return True if the cvar has a boundary set, false otherwise * @error If an invalid cvar pointer or boundary type is provided, * an error will be thrown. */ native bool:get_pcvar_bounds(pcvar, CvarBounds:type, &Float:value);
set_pcvar_bounds	⇅ To set a boundary /** * Sets the specified boundary of a cvar. * * @param pcvar Pointer to cvar * @param type Type of boundary to set * @param set If true the cvar boundary will be set, otherwise it will be * removed (value is ignored) * @param value Floating point value to use as the boundary * * @noreturn * @error If an invalid cvar pointer or boundary type is provided, an * error will be thrown. */ native set_pcvar_bounds(pcvar, CvarBounds:type, bool:set, Float:value = 0.0);

Note:CvarBounds has the following values:

• CvarBound_Upper
• CvarBound_Lower

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    new const pointer = register_cvar("amx_leet", "1337");
 
    // Defines min and max value
    set_pcvar_bounds(pointer, CvarBound_Lower, .set = true, 0.0);
    set_pcvar_bounds(pointer, CvarBound_Upper, .set = true, 42.0);
 
    // Current value should be "42".
    server_print("amx_something current value: %f", get_pcvar_float(pointer));
 
    // Removes the lower bound.
    set_pcvar_bounds(pointer, CvarBound_Lower, .set = false);
 
    new Float:value;
 
    if (get_pcvar_bounds(pointer, CvarBound_Upper, value))
    {
        server_print("amx_something should have an upper bound: %f", value);
    }
 
    if (!get_pcvar_bounds(pointer, CvarBound_Upper, value))
    {
        server_print("amx_something should not have an lower bound);
    }
}

Constant

A missing FCVAR_NOEXTRAWHITEPACE flag has been added.
It automatically strips trailing/leading white space from the string value.

Creating

A new create_cvar ⇅ native has been added, similar to register_cvar but with two new features:

/**
 * Creates a new cvar for the engine.
 *
 * @note This has the same effect as register_cvar() but provides more options.
 * @note For a list of possible cvar flags see FCVAR_* constants above.
 * @note If an already existing cvar is registered it will not be duplicated.
 *       The default value is only set when the cvar is registered for the very
 *       first time since the server was started. Cvar bounds are overwritten
 *       by the create_cvar() call just as if they were re-set using
 *       set_pcvar_bounds().
 * @note The returned cvar pointer should be used with the get_pcvar_* and
 *       set_pcvar_* set of functions.
 *
 * @param name          Cvar name
 * @param string        Default cvar value
 * @param flags         Optional bitsum of flags specifying cvar behavior
 * @param description   Optional description of the cvar
 * @param has_min       Optional boolean that specifies if the cvar has a
 *                      minimum value
 * @param min_val       Minimum floating point value
 * @param has_max       Optional boolean that specifies if the cvar has a
 *                      maximum value
 * @param max_val       Maximum floating point value
 *
 * @return              Unique cvar pointer
 * @error               If invalid bounds are provided (min_val > max_val or
 *                      vice versa), an error will be thrown.
 */
native create_cvar(const name[], const string[], flags = FCVAR_NONE, const description[] = "", bool:has_min = false, Float:min_val = 0.0, bool:has_max = false, Float:max_val = 0.0);

Description	Similar to command, you can explain shorlty what does the cvar. The message can be retrieved with get_plugins_cvar and can be read from amxx cvars detailed output. The description is used with AutoExecConfig for example.
Boudary	You can set directly a boudary, either a minimum value, a maximum value or both.

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    create_cvar("amx_something1", "1", FCVAR_NONE, "My description here", true, 1.0, true, 42.0);
    create_cvar("amx_something2", "2", .description = "My description here", .has_min = true, min_val = 1.0, .has_max = true, .max_val = 42.0);
    create_cvar("amx_something3", "3", .has_min = true, min_val = 1.0);
    create_cvar("amx_something4", "4", .has_max = true, max_val = 42.0);
}

Command

The amxx cvars shows now more informations about a cvar state. Here an example of output:

Managed cvars:

Others

Native	Description
get_pcvar_bool	⇅ Returns an boolean value from a cvar via direct pointer access. /** * Returns an boolean value from a cvar via direct pointer access. * * @param pcvar Pointer to cvar to retrieve value from * * @return Cvar value, converted to bool * @error If an invalid cvar pointer is provided, an error will be * thrown. */ native bool:get_pcvar_bool(pcvar);
set_pcvar_bool	⇅ Sets a boolean value to a cvar via direct pointer access. /** * Sets a boolean value to a cvar via direct pointer access. * * @param pcvar Pointer to cvar to set value of * @param num Value to set cvar to * * @noreturn * @error If an invalid cvar pointer is provided, an error will be * thrown. */ native set_pcvar_bool(pcvar, bool:num);

CellArray

A bunch of natives have been added to complete the existing API. You are now able to:

• Clone an array
• Resize an array
• Find a value or string inside an array
• Control more precisely how the data is retrieved/saved

Note:Arrays are heterogeneous. This means you can save different data types into a list.
A good example is the Stack Structure API which is actually based on Array (internal library, that's it).

Note:Initially the reserved parameter in ArrayCreate was intended to create blank entries that would immediately be usable with ArrayGet/Set functions.
This functionality was never working as intended, and can now be achieved using ArrayResize.

Cloning

Native	Description
ArrayClone	⇅ Clones an array. /** * Clones an array, returning a new handle with the same size and data. * * @param which Array handle * * @return Handle to the cloned array on success, 0 otherwise * @error If an invalid handle is provided an error will be * thrown. */ native Array:ArrayClone(Array:which);

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    new Array:list = ArrayCreate();
 
    ArrayPushCell(list, 1);
    ArrayPushCell(list, 2);
    ArrayPushCell(list, 3);
 
    new Array:clone_list = ArrayClone(list);
 
    //
 
    ArrayDestroy(clone_list);
    ArrayDestroy(list);
}

Resizing

Native	Description
ArrayResize	⇅ Resizes an array. /** * Resizes an array. * * @note If the size is smaller than the current array size the array is * truncated and data lost. * * @param which Array handle * @param newsize New size * * @noreturn * @error If an invalid handle is provided or the resizing * operation runs out of memory, an error will be thrown. */ native bool:ArrayResize(Array:which, newsize);

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    new Array:list = ArrayCreate(.cellsize = 1, .reserved = 3);
 
    ArrayPushCell(list, 1);
    ArrayPushCell(list, 2);
    ArrayPushCell(list, 3);
 
    new const count = ArraySize(list);
 
    ArrayResize( list, count + 1); // Add a new allocated and available slot
    ArraySetCell(list, count, 4);  // Notice you can use directly ArraySet
 
    server_print("Last value = %d, Cloned list size = %d", ArrayGetCell(list, count), ArraySize(list)); // Should be 4.
 
    ArrayDestroy(list);
}

Finding a value

Native	Description
ArrayFindValue	⇅ Searches through the array and returns the index of the first occurence of the specified value. /** * Searches through the array and returns the index of the first occurence of * the specified value. * * @param which Array handle * @param item Value to search for * * @return Array index on success, -1 if the value can't be found * @error If an invalid handle is provided an error will be * thrown. */ native ArrayFindValue(Array:which, any:item);
ArrayFindString	⇅ Searches through the array and returns the index of the first occurence of the specified string. /** * Searches through the array and returns the index of the first occurence of * the specified string. * * @param which Array handle * @param item String to search for * * @return Array index on success, -1 if the string can't be found * @error Invalid handle. */ native ArrayFindString(Array:which, const item[]);

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    new Array:list = ArrayCreate(.cellsize = 16);
 
    ArrayPushString(list, "something");
    ArrayPushString(list, "is");
    ArrayPushCell(list, 42);
    ArrayPushString(list, "hidden");
 
    new index = ArrayFindValue(list, 42);
    server_print("Cell index = %d", index); // should be 2
 
    index = ArrayFindString(list, "hidden");
    server_print("String index = %d", index); // should be 3
 
    ArrayDestroy(list);
}

Sorting

Along two new ArraySort and SortADTArray natives, there is also a new Sort_Random method.

Native	Description
ArraySortEx	⇅ A faster version of ArraySort. /** * A faster version of ArraySort, the sorting algorithm then uses the custom * comparison function to sort the data. * * @note The advantage of this function is that the data of the elements being * compared is directly passed to the function, instead of the item * indexes that are passed by ArraySort. This removes the need for calling * ArrayGet[Cell|String|Array] every time before being able to compare the * elements. * * @note For Arrays with a cellsize of 1 (used for storing integers and floats), * the function is called in the following manner: * * public MySortFunc(Array:array, elem1, elem2, const data[], data_size) * * array - Array handle in its current un-sorted state * elem1, elem2 - Current element pair being compared * data[] - Extra data array passed to the sort func * data_size - Size of extra data * * @note For Arrays with a cellsize larger than 1 (used for storing arrays and * strings), the function is called in the following manner: * * public MySortFunc(Array:array, elem1[], elem2[], const data[], data_size) * * array - Array handle in its current un-sorted state * elem1[], elem2[] - Current element pair being compared * data[] - Extra data array passed to the sort func * data_size - Size of extra data * * * @note The comparison function should return: * -1 if elem1 should go before elem2 * 0 if elem1 and elem2 are equal * 1 if elem1 should go after elem2 * * @note All parameters after item2 are optional and do not need to be specified * and used. * @note Unlike the sorting.inc version, the array passed to the callback is not * in mid-sorted state. * * @param array Array handle * @param comparefunc Callback function used for comparison * @param data Extra data that is passed through to the callback * @param data_size Size of extra data * * @noreturn * @error If an invalid handle or an invalid callback is provided * an error will be thrown. */ native ArraySortEx(Array:array, const comparefunc[], data[]="", data_size=0);
SortADTArray	⇅ To sort directly with a sort method. /** * Sort an ADT Array. Specify the type as Integer, Float, or String. * * @param array Array Handle to sort * @param order Sort order to use, same as other sorts. * @param type Data type stored in the ADT Array * @noreturn */ native SortADTArray(Array:array, SortMethod:order, SortType:type); Note:SortMethod has the following values: Sort_Ascending Sort_Descending Sort_Random

New params

Native	parameter	Description
ArrayGetArray ArraySetArray ArrayPushArray	size	⇅ Controls the number of elements to use. /** * @param size If not set, assumes the buffer size is equal to the * cellsize. Otherwise, the specified size is used. */ native ArrayGetArray(Array:which, item, any:output[], size = -1); native ArraySetArray(Array:which, item, const any:input[], size =-1); native ArrayPushArray(Array:which, const any:input[], size = -1);
ArrayGetCell ArraySetCell	achar block	⇅ Specifies which block and retrieves a value as byte. /** * @param block If the array has a cellsize >1 this optionally specifies * which block to read from * @param asChar If true reads the value as a byte instead of a cell */ native any:ArrayGetCell(Array:which, item, block = 0, bool:asChar = false);

CellTrie

The word "Trie" in this API is historical. As of AMX Mod X 1.9, tries have been internally replaced with hash tables, which have O(1) insertion time instead of O(n).
As consequence, the API has been completed and you can now:

• Get a trie size
• Control more precisely the data on insertion/retrieval
• Iterate over a trie

Note:Tries are heterogeneous. This means you can save different data types into a list.

Getting size

Native	Description
TrieGetSize	⇅ Returns the number of entries in a hash map. /** * Returns the number of entries in a hash map. * * @param handle Map handle * * @return Number of elements in the hash map * @error If an invalid handle is provided an error will be * thrown. */ native TrieGetSize(Trie:handle);

Iterating

There are two ways to iterate over a trie:

• Snapshots

As the name suggested, it will duplicate the whole set of keys (only) into a separate list. Any changes to the original list will not affect the snapshot.
It's an expensive operation, but can be stored.

Native	Description
TrieSnapshotCreate	⇅ Creates a snapshot of all keys in a hash map. /** * Creates a snapshot of all keys in a hash map. If the map is changed * afterwards, the changes are not reflected in the snapshot. * Keys are not sorted. * * @param handle Map handle * * @return New map snapshot handle, which must be freed via * TrieSnapshotDestroy() * @error If an invalid handle is provided an error will be * thrown. */ native Snapshot:TrieSnapshotCreate(Trie:handle);
TrieSnapshotLength	⇅ Returns the number of keys in a map snapshot. /** * Returns the number of keys in a map snapshot. Note that this may be * different from the size of the map, since the map can change after the * snapshot of its keys was taken. * * @param handle Map snapshot handle * * @return Number of keys * @error If an invalid handle is provided an error will be * thrown. */ native TrieSnapshotLength(Snapshot:handle);
TrieSnapshotGetKey	⇅ Retrieves the key string of a given key in a map snapshot. /** * Retrieves the key string of a given key in a map snapshot. * * @param handle Map snapshot handle * @param index Key index (starting from 0) * @param buffer String buffer * @param maxlength Maximum buffer length * * @return Number of bytes written to the buffer * @error If an invalid handle is provided an error will be * thrown. or index out of range */ native TrieSnapshotGetKey(Snapshot:handle, index, buffer[], maxlength);
TrieSnapshotDestroy	⇅ Retrieves the key string of a given key in a map snapshot. /** * Destroys a map snapshot and frees its memory. * * @note The function automatically sets the variable passed to it to 0 to aid * in preventing accidental usage after destroy. * * @param handle Map snapshot handle * * @return 1 on success, 0 if an invalid handle was passed in */ native TrieSnapshotDestroy(&Snapshot:handle);

Note:The keys are not sorted.

Example:⇅

#include <amxmodx>
 
public plugin_init()
{
    new Trie:list = TrieCreate();
    {
        TrieSetString(list, "adventure", "time!");
        TrieSetString(list, "butterflies", "bees");
        TrieSetString(list, "egg", "egg");
    }
 
    new Snapshot:keys = TrieSnapshotCreate(list);
    {
        new const length = TrieSnapshotLength(keys);
        new key[32];
 
        for (new const i = 0; i < length; ++i)
        {
            TrieSnapshotGetKey(keys, i, buffer, charmax(buffer));
            server_print("buffer = %s", buffer);
        }
    }
 
    TrieSnapshotDestroy(keys);
}

• Iterator

A contrario, Iterators are designed to be short-lived and not stored, and creating them is very cheap.
Reading data from an iterator is just as fast as reading directly from the map.
This is useful if you just need to iterate (or eventually updating values of existing keys, which is allowed)

Native	Description

File

Valve FileSystems

Thanks to the IFileSystem interface from HLSDK, we are now able to make more operations possible with files via Valve File System through Valve search paths (example: download directory).
This is handy when you want to deal with files which are not necessary existing directly in the game directory.

Not all natives are concerned. This features some new natives and enhanced others existing ones with small quality of life changes.

Valve Paths

Path ID	Description
GAME	All paths related to current mod, including fallback. Depending settings, it includes: <gamedir>_lv/_addon/_language/_hd and <gamedir> itself.
GAMECONFIG	The default writable directory: <gamedir>.
GAMEDOWNLOAD	The download directory: <gamedir>_download.
GAME_FALLBACK	All paths related to fallback game, same as GAME (example: czero has cstrike as fallback. Others mods have usually the default game valve, including cstrike).
DEFAULTGAME	All paths related to the default game which is valve, same as GAME.
BASE	The base path where server is installed.

Native Support

Some natives supports partially Valve FS, where a path ID can't be provided and this will search in all paths instead.

Native	parameter	Description
delete_file unlink file_exists partially dir_exists partially file_size fopen mkdir open_dir	use_valve_fs valve_path_id	⇅ Uses the Valve file system via a search path from gameinfo. /** * @note Registered paths ID are (in priority order) : * GAME All paths related to current mod, including fallback * Depending settings, it includes: <gamedir>_lv/_addon/_<language>/_hd * and <gamedir> itself * GAMECONFIG The default writable directory (<gamedir>) * GAMEDOWNLOAD The download directory (<gamedir>_download) * GAME_FALLBACK All paths related to fallback game, same as GAME * DEFAULTGAME All paths related to the default game which is "valve", same as GAME * BASE The base path where server is installed * * Note that some paths are non-writable. It includes all <gamedir>_* (expect _download) * and DEFAULTGAME. Any file inside a non-writable path will be ignored if you try to open * it in writing mode. * * @param use_valve_fs If true, the Valve file system will be used instead * This can be used to finred files existing in valve * search paths, rather than solely files existing directly * in the gamedir. * @param valve_path_id If use_valve_fs, a search path from gameinfo or NULL_STRING for all search paths */

Some natives are not adjusted because not exposed by Valve FS:

• rename_file
• rmdir

Others

There are as well some minor additions or changes:

• Added a new define PLATFORM_MAX_PATH ⇅ to represent a maximum path length.

/**
 * Maximum path length.
 */
#define PLATFORM_MAX_PATH  256

• Added any: tag to some natives.
• read_dir: outlen parameter is now optional.
• read_file: txtlen parameter is now optional. Adjusted as well buffer to 2048 to match buffer size in write_file.
• file_size: Fixed potential issue with old compiled plugin which doesn't have the flag parameter. Added FSOPT_* ⇅ constants as well for use with this flag parameter.

/**
 * Options for use with file_size() flag parameter.
 */
#define FSOPT_BYTES_COUNT  0  /* Returns the file size in number of bytes */
#define FSOPT_LINES_COUNT  1  /* Returns how many lines there are in this file */

Menu

Timeout

Timeout is now added to newmenus, working similar to those of show_menu.

When a menu is acted upon after the specified timeout has run out it will pass a new MENU_TIMEOUT status code into the menu handler.
Actions are:

• player disconnect
• selecting an item,
• cancelling/destroying the menu in the plugin,
• sending a different menu or using get_user_menu on a player with an open menu.

Just like with the old menus timeouts are not actively polled, and MENU_TIMEOUT is not guaranteed to fire directly after the time has run out.
Also get_user_menu will detect timeouts and reset the menu flags, which is why it also has to trigger the callback.

Note:An example is available at PR 21.

Native	parameter	Description
menu_display	time	⇅ If >=0 menu will timeout after this many seconds. /** * Displays a menu to one client. This should never be called from a handler * when the item is less than 0 (i.e. calling this from a cancelled menu will * result in an error). * * Starting with 1.8.3 this allows to specify a menu timeout similar to the * show_menu native.

Conversion

Native	Description
strtol	⇅ Parses the string interpreting its content as an integral number of the specified base, which is returned as integer value. The function also sets the value of endPos to point to the position of the first character after the number. /** * Parses the 'string' interpreting its content as an integral number of the specified 'base', * which is returned as integer value. The function also sets the value of 'endPos' to point * to the position of the first character after the number. * * This is the same as C++ strtol function with a difference on second param. * * The function first discards as many whitespace characters as necessary until the first * non-whitespace character is found. Then, starting from this character, takes as many * characters as possible that are valid following a syntax that depends on the 'base' parameter, * and interprets them as a numerical value. Finally, a position of the first character following * the integer representation in 'string' is stored in 'endPos'. * * If the value of 'base' is zero, the syntax expected is similar to that of integer constants, * which is formed by a succession of : * An optional sign character (+ or -) * An optional prefix indicating octal or hexadecimal base ("0" or "0x"/"0X" respectively) * A sequence of decimal digits (if no base prefix was specified) or either octal or hexadecimal digits if a specific prefix is present * * If the 'base' value is between 2 and 36, the format expected for the integral number is a succession * of any of the valid digits and/or letters needed to represent integers of the specified radix * (starting from '0' and up to 'z'/'Z' for radix 36). The sequence may optionally be preceded by * a sign (either + or -) and, if base is 16, an optional "0x" or "0X" prefix. * * If the first sequence of non-whitespace characters in 'string' is not a valid integral number * as defined above, or if no such sequence exists because either 'string' is empty or it contains * only whitespace characters, no conversion is performed. * * @param string The string to parse. * @param endPos The position of the first character following the number. * On success and when containing only numbers, position is at the end of string, meaning equal to 'string' length. * On failure, position is sets always to 0. * @param base The numerical base (radix) that determines the valid characters and their interpretation. * If this is 0, the base used is determined by the format in the sequence. * @return On success, the function returns the converted integral number as integer value. * If no valid conversion could be performed, a zero value is returned. * If the value read is out of the range of representable values by a cell, * the function returns 'cellmin' or 'cellmax'. */ native strtol(const string[], &endPos = 0, base = 0);

Format specifier

Specifier	Description
%b	Binary digits in the value
%n	Requires a client index. Expands to a string containing the player's name. If the client index is 0, the string will be: Console
%N	Requires a client index. Expands to 1<2><3><4> where 1 is the player's name, 2 is the player's userid, 3 is the player's SteamID, and 4 the player's team name. If the client index is 0, the string will be: Console<0><Console><Console>
%l	Translates a phrase from a key. Similar to %L with the difference it will use the client's index set internally by the function. This is only allowed in functions which act directly on one or more clients. Note:To complement this, a new ⇅ SetGlobalTransTarget native to set the current index has been added. This is useful to be used before with natives which are not player-oriented", like a bunch of formatex. /** * Sets the global language target. * * @note This is useful for creating functions * that will be compatible with the %l format specifier. Note that invalid * indexes can be specified but the error will occur during translation, * not during this function call. * * @param client Client index or LANG_SERVER * @noreturn */ native SetGlobalTransTarget(client); Example:⇅ client_print(index, print_chat, "%L", index, "EGG"); can be now client_print(index, print_chat, "%l", "EGG");

Formatting

Existing module APIs additions

AMXX SDK

the following functions have been added:

Function	Description
MF_SetAmxStringUTF8Char	Sets UTF-8 string from char* input
MF_SetAmxStringUTF8Cell	Sets UTF-8 string from cell* input
MF_GetAmxStringNull	Gets string with NULL_STRING support
MF_GetAmxVectorNull	Gets a vector with NULL_VECTOR support
MF_GetConfigManager	Gets the config manager for use with gamedata files
MF_LoadAmxScriptEx	Saner version of MF_LoadAmxScript which explicits error max length

CStrike

All hardcoded game datas are now moved to its own gamedata file located in data/gamedata/modules.games/game.cstrike.txt.
See AMX_Mod_X_1.9_Release_Notes#Gamedata for more information.

Constant

Numerous constants from the game have added. See the cstrike_const.inc.

Additionally for two natives:

• CS_NORESET constant for use with cs_set_user_team for skipping the model reset
• TRAIN_* ⇅ constants for use with cs_get_user_driving

/**
 * Train status values
 */
#define TRAIN_ACTIVE  0x80
#define TRAIN_NEW     0xc0
 
#define TRAIN_OFF     0x00
#define TRAIN_NEUTRAL 0x01

#define TRAIN_FAST    0x04
#define TRAIN_BACK    0x05

Entity

Native	Description
cs_create_entity	⇅ Creates an entity using Counter-Strike's custom CreateNamedEntity wrapper. Note:Unlike other mods CS keeps track of entities using a custom hashtable. This function adds entities to this hashtable, providing benefits over the default CreateNamedEntity (used by create_entity for example): Storing entities in a hashtable allows CS to improve classname lookup performance compared to functions like FindEntityByString (used by find_ent_by_class for example) that usually have to loop through all entities incrementally. As CS exclusively uses the hashtable for classname lookup, entities created using the default engine functions will not be found by the game. For example "weaponbox" entities are supposed to be automatically cleaned up on round restart but are not considered if they have not been added to the hashtable. /** * Creates an entity using Counter-Strike's custom CreateNamedEntity wrapper. * * @note Unlike other mods CS keeps track of entities using a custom hashtable. * This function adds entities to this hashtable, providing benefits over * the default CreateNamedEntity (used by create_entity() for example): * - Storing entities in a hashtable allows CS to improve classname lookup * performance compared to functions like FindEntityByString (used by * find_ent_by_class() for example) that usually have to loop * through all entities incrementally. * - As CS exclusively uses the hashtable for classname lookup, entities * created using the default engine functions will not be found by the * game.

cs_find_ent_by_class cs_find_ent_by_owner	⇅ Finds an entity in the world using Counter-Strike's custom FindEntityByString wrapper. /** * Finds an entity in the world using Counter-Strike's custom FindEntityByString * wrapper. * * @note Unlike other mods CS keeps track of entities using a custom hashtable. * This function utilizes the hasthable and allows for considerably faster * classname lookup compared to the default FindEntityByString (used by * find_ent_by_class() for example). * @note This exclusively considers entities in the hashtable, created by the * game itself, using cs_create_entity(), or added via cs_set_ent_class(). * * @param start_index Entity index to start searching from. -1 to start from * the first entity * @param classname Classname to search for * * @return Entity index > 0 if found, 0 otherwise */ native cs_find_ent_by_class(start_index, const classname[]); ⇅ Finds an entity in the world using Counter-Strike's custom FindEntityByString wrapper, matching by owner. /** * Finds an entity in the world using Counter-Strike's custom FindEntityByString * wrapper, matching by owner. * * @note Unlike other mods CS keeps track of entities using a custom hashtable. * This function utilizes the hasthable and allows for considerably faster * classname lookup compared to the default FindEntityByString (used by * find_ent_by_owner() for example). * @note This exclusively considers entities in the hashtable, created by the * game itself, using cs_create_entity(), or added via cs_set_ent_class(). * * @param start_index Entity index to start searching from. -1 to start from * the first entity * @param classname Classname to search for * @param owner Entity index to search for entity's owner * * @return Entity index > 0 if found, 0 otherwise */ native cs_find_ent_by_owner(start_index, const classname[], owner); Note:Those functions utilize the hasthable and allows for considerably faster classname lookup compared to the default FindEntityByString (used by find_ent_by_class for example). This exclusively considers entities in the hashtable, created by the game itself, using cs_create_entity, or added via cs_set_ent_class).
cs_set_ent_class	⇅ Sets a custom classname of an entity. Note:This function adds or updates the classname in the hasthable as well. This is useful for use with cs_find_ent_by_class and cs_find_ent_by_owner. /** * Sets a custom classname of an entity. * * @note Unlike other mods CS keeps track of entities using a custom hashtable. * This function adds or updates the classname in the hasthable as well. * This is useful for use with cs_find_ent_by_class() and cs_find_ent_by_owner(). * * @param index Entity index * @param classname Classname to update for * * @noreturn */ native cs_set_ent_class(index, const classname[]);

Buying

You can now easily detect when an item is being purchased.

Forward	Description
CS_OnBuyAttempt	⇅ Called when a client attempts to purchase an item. Note:This is called immediately when the client issues a buy command. The game has not yet checked if the client can actually buy the weapon. /** * Called when a client attempts to purchase an item. * * @note This is called immediately when the client issues a buy command. The * game has not yet checked if the client can actually buy the weapon. * @note For a list of possible item ids see the CSI_* constants. * * @param index Client index * @param item Item id * * @return PLUGIN_CONTINUE to let the buy attempt continue * PLUGIN_HANDLED to block the buy attempt */ forward CS_OnBuyAttempt(index, item);
CS_OnBuy	⇅ Called when a client purchases an item. Note:This is called right before the user receives the item and before the money is deducted from their cash reserves. /** * Called when a client purchases an item. * * @note This is called right before the user receives the item and before the * money is deducted from their cash reserves. * @note For a list of possible item ids see the CSI_* constants. * * @param index Client index * @param item Item id * * @return PLUGIN_CONTINUE to let the buy continue * PLUGIN_HANDLED to block the buy */ forward CS_OnBuy(index, item);

Miscellaneous

• get/set_pdata_cbase can now be used at map end whereas player's private datas are still valid.
• EngFunc_PlayBackEvent can now receive a null invoker.
• KeyValueData usage is now compatible with Hamsandwich module.

GeoIP

Library

The module uses the new MaxMind GeoIP2 API. The relevant advantages are:

• Should be more precise
• Data is localized (current supported languages: de, en, es, fr, ja, ru, pt-BR, zh-CN)

If you want further information, see What’s New in GeoIP2.

Note:GeoIP.dat is replaced with GeoLite2-Country.mmdb (default, downloadable) or GeoLite2-City.mmdb (downloadable).

Command

A geoip command is available for troubleshooting: geoip <command> [argument]

Deprecated natives

geoip_country has been marked as deprecated in favor of geoip_country_ex.
Hardcoding the maximum buffer length and returning "error" if nothing is found, were not quite the good idea.

New natives

The natives which can output localized data, have a new id ⇅ parameter in order to retrieve data into the player's language.

/**
 * @param id        An optional player's index in order to return the result
 *                  in the player's language, if supported.

MySQL

Connectivity

To improve the connectivity, few features have been added.

Feature	Description
Reconnection	This has MySQL automatically reconnects if times out or loses connection through MYSQL_OPT_RECONNECT option. This should prevent "MySQL server has gone away" errors after a while.
Timeout	This establishes a default read/write timeout for MySQL connectivity through MYSQL_OPT_CONNECT_TIMEOUT option. A new option to set globally the timeout (60s by default) can be found in core.ini ⇅ and a new amx_sql_timeout cvar in sql.cfg ⇅. ; MySQL default timeout mysql_timeout 60 amx_sql_timeout "60"

Miscellaneous

• Module threading has been updated to be more responsive. This should help in reducing potential hang up in situations such as on change map or lost connection.

Character Set

Description

MySQL_SetCharset

⇅ Sets the character set of the current connection. /** * Sets the character set of the current connection. * Like SET NAMES .. in mysql, but stays after connection problems. * * If a connection tuple is supplied, this should be called before SQL_Connect or SQL_ThreadQuery. * Also note the change will remain until you call this function with another value. * This native does nothing in SQLite. * * Example: "utf8", "latin1" * * @param h Database or connection tuple Handle. * @param charset The character set string to change to. * @return True, if character set was changed, false otherwise. */ native bool:SQL_SetCharset(Handle:h, const charset[]);

RegEx

Library

The internal PCRE library version has been updated from 6.4 to 8.35 and has been compiled with UTF-8 support.
If you are interested, see the changelog.

Miscellaneous

• regex_subtr: The internal static buffer has been increased to match the same size as core and has been made UTF-8 safe.
• The maximum number of sub-patterns has been increased from 30 to 150.

JSON

A JSON module is now part of the official AMX Mod X package.

Essentially:

• Supports decoding and encoding (also with pretty format)
• Relies on Parson, which is lighweight and simple JSON library written in C
• Supports dot notation (Values can be accessed by typing objectA.objectB.value)
• Allows us to iterate through arrays and objects

Note:Examples are available on Github an in the testsuite directory, see textparse.sma.
