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__`	Name of the compiled plugin. Example: `admin.amxx`
`__BINARY_PATH__`	Absolute path to the compiled plugin. Example: `/home/hlds/cstrike/addons/amxmodx/plugins/admin.amxx`
`__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"

        "Signatures"
        {
            "SV_DropClient"

                "windows"   "\x55\x8B\x2A\x81\x2A\x2A\x2A\x2A\x2A\x8B\x2A\x2A\x53\x56\x8D"
                "linux"     "@SV_DropClient"

                "windows"
                {

                }
 
                "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);

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"
 *   {

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.

Forward Description

client_connectex

 * @param ip        Client ip address with port
 * @param reason    A reason that will be displayed when player gets rejected (can be overwritten)
 *
 * @return          PLUGIN_CONTINUE to let a client join to the server
 *                  PLUGIN_HANDLED or higher to prevent a client to join
 */

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:

native bool:get_pcvar_bool(pcvar);

set_pcvar_bool

⇅ Sets a boolean value to a cvar via direct pointer access.

 *                  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.

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
`TrieIterCreate`	⇅ Creates an iterator for a map. /** * Creates an iterator for a map. It provides iterative read-only access to the * maps contents. * * @note Removing or adding keys to the underlying map will invalidate all its * iterators.

Reading data from an iterator is just as fast as * reading directly from the map. * @note Just like in snapshots the keys are not sorted. * * @return New iterator handle, which must be freed via TrieIterDestroy(). * @error Invalid Handle */ native TrieIter:TrieIterCreate(Trie:handle);
`TrieIterEnded`	⇅ Returns if the iterator has reached its end and no more data can be read. /** * Returns if the iterator has reached its end and no more data can be read. * * @param handle Iterator handle * * @return True if iterator has reached the end, false otherwise * @error Invalid Handle * Iterator has been closed (underlying map destroyed) * Iterator is outdated */ native bool:TrieIterEnded(TrieIter:handle);
`TrieIterNext`	⇅ Advances the iterator to the next key/value pair if one is available. /** * Advances the iterator to the next key/value pair if one is available. * * @param handle Iterator handle * * @error Invalid Handle * Iterator has been closed (underlying map destroyed) * Iterator is outdated */ native TrieIterNext(TrieIter:handle);
`TrieIterGetKey`	⇅ Retrieves the key the iterator currently points to. /** * Retrieves the key the iterator currently points to. * * @param handle Iterator handle. * @param key Buffer to store the current key in. * @param outputsize Maximum size of string buffer. * * @return Nnumber of bytes written to the buffer * @error Invalid handle * Iterator has been closed (underlying map destroyed) * Iterator is outdated */ native TrieIterGetKey(TrieIter:handle, key[], outputsize);
`TrieIterGetSize`	⇅ Retrieves the number of elements in the underlying map. /** * Retrieves the number of elements in the underlying map. * * @note When used on a valid iterator this is exactly the same as calling TrieGetSize on the map directly. * * @param handle Iterator handle * * @return Number of elements in the map * @error Invalid handle * Iterator has been closed (underlying map destroyed) * Iterator is outdated */ native TrieIterGetSize(TrieIter:handle);
`TrieIterGetCell`	⇅ Retrieves a value at the current position of the iterator. /** * Retrieves a value at the current position of the iterator. * * @param handle Iterator handle * @param value Variable to store value in * * @return True on success, false if the iterator is empty or the current * value is an array or a string. * @error Invalid handle * Iterator has been closed (underlying map destroyed) * Iterator is outdated */ native bool:TrieIterGetCell(TrieIter:handle, &any:value);

`TrieIterDestroy`	⇅ Destroys an iterator handle. /** * Destroys an iterator handle. * * @param handle Iterator handle. * * @return True on success, false if the value was never set. */ native TrieIterDestroy(&TrieIter:handle);

Note:The keys are not sorted.

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.

/**

 *         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

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 */
#define FSOPT_END_WITH_LF  2  /* Returns whether the last line is '\n' */

General

Constant

Added DMG_GRENADE constant (Counter-Strike only)
Added missing SVC_ messages (PR 223)
- SVC_RESOURCELOCATION
- SVC_SENDCVARVALUE
- SVC_SENDCVARVALUE2

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'.

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

set_fail_state has now the ability to format a text.
A new native for simple inline formatting:

Native Description

fmt

⇅ Formats and returns a string according to the AMX Mod X format rules.

Note:This should only be used for simple inline formatting like in the above example.
Avoid using this function to store strings into variables as an additional copying step is required.

Note:The buffer size is defined by MAX_FMT_LENGTH.

Example:⇅

menu_additem(menu, fmt("My first %s", "item"))

/**
* Formats and returns a string according to the AMX Mod X format rules
* (see documentation).
*
* @note Example: menu_additem(menu, fmt("My first %s", "item")).

strtok2

⇅ Breaks a string in two by token.

Note:This function has been added due to strtok being buggy in some situations.

Trim flags:⇅

/**
 * Below are the trim flags for strtok2
 *
 * You can specify how the left and right buffers will
 * be trimmed by strtok2. LTRIM trims spaces from the
 * left side. RTRIM trims from the right side.
 *
 * The defines TRIM_INNER, TRIM_OUTER and TRIM_FULL are
 * shorthands for commonly used flag combinations.
 *
 * When the initial string is trimmed, using TRIM_INNER
 * for all subsequent strtok2 calls will ensure that left
 * and right are always trimmed from both sides.
 *
 * Examples:
 * str1[] = "  This is  *  some text  "
 * strtok2(str1, left, 24, right, 24, '*', TRIM_FULL)
 *  left will be "This is", right will be "some text"
 *
 * str2[] = "  Here is  |  an  | example  "
 * trim(str2)
 * strtok2(str2, left, 24, right, 24, '|', TRIM_INNER)
 *  left will be "Here is", right will be "an  | example"
 * strtok2(right, left, 24, right, 24, '|', TRIM_INNER)
 *  left will be "an", right will be "example"
 *
 * str3[] = "  One  -  more  "
 * strtok2(str3, left, 24, right, 24, '-', TRIM_OUTER)
 *  left will be "One  ", right will be "  more"
 *
 * str4[] = "  Final  .  example  "
 * strtok2(str4, left, 24, right, 24, '.', LTRIM_LEFT|LTRIM_RIGHT)
 *  left will be "Final  ", right will be "example  "

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

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

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.

Gamerules

You have now the ability to manage a value using the gamerules object based off a class and member name.
The gamedata files are located in /data/gamedata/common.games/gamerules.games directory.

Example:⇅

foo()
{
    new const score = get_gamerules_int("CHalfLifeMultiplay", "m_iNumCTWins");
}

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).

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.

ItemInfo structure

A new set of functions have added to manage the {ItemInfo structure.

Native	Description
`CreateHamItemInfo`	⇅ Creates an ItemInfo handle. The handle can be used in `GetHamItemInfo` and `SetHamItemInfo`. /** * Creates an ItemInfo handle. This value should never be altered. * The handle can be used in Get/SetHamItemInfo. * * NOTE: You must call FreeHamItemInfo() on every handle made with CreateHamItemInfo(). * * @return A new ItemInfo handle. */ native CreateHamItemInfo();

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

Stock 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.

New Natives & Stocks

Native Description

Socket

WinSock is now update from version 1.1 to 2.2
Natives won't be registered if WinSock can't be started

Improvements

Native Parameter Description

⇅ socket_open

_flags

The following flags are additive:

SOCK_NON_BLOCKING: if set, the socket will be on nonblocking mode
SOCK_LIBC_ERRORS: f set, the new libc errors will be seen on _error

/**
 * Error reporting
 */
#define SOCK_ERROR_OK               0 /* No error */
#define SOCK_ERROR_CREATE_SOCKET    1 /* Couldn't create a socket */
#define SOCK_ERROR_SERVER_UNKNOWN   2 /* Server unknown */
#define SOCK_ERROR_WHILE_CONNECTING 3 /* Error while connecting */
 
/**
 * Connects to the given node and service via TCP/UDP.

 * @note There's 2 types of error reporting on this function that you can use.
 * @note Default error codes:
 *       0 - No error
 *       1 - Error while creating socket
 *       2 - Couldn't resolve hostname
 *       3 - Couldn't connect
 * @note New, more expressive libc error codes:
 *       https://www.gnu.org/software/libc/manual/html_node/Error-Codes.html
 *       https://github.com/torvalds/linux/blob/master/include/uapi/asm-generic/errno.h

 *       - SOCK_LIBC_ERRORS : if set, the new libc errors will be seen on _error
 *
 * @note If no flags are set, the behaviour of the function will not be modified.
 *
 * @note Multiple flags may be set at the same time using the | operator. 
 *       For example, SOCK_NON_BLOCKING|SOCK_LIBC_ERRORS will create a nonblocking socket with libc error codes.
 *
 * @note If you're creating a new nonblocking socket, _hostname should be numeric to avoid calling the 
 *       name resolution server and potentially blocking the call.
 *
 * @note If the socket is a nonblocking one, the returned socket descriptor may be still connecting and 
 *       further checks should be done with socket_is_writable() before trying to send data.

SQLite

Library

The SQLite library version has been updated from 3.3.13 to 3.8.8.2.
If you are interested, see the changelog.

Character Set

Stock Description

SQL_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.

Miscellaneous

The queuetime value is now properly passed to the SQL_ThreadQuery callback.

New module

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.
