AMX Mod X 1.76 Changes

2006-11-16T22:32:33Z

MaximusBrood:

AMX Mod X 1.76 is a small feature release and contains mostly bug fixes.
AMX Mod X 1.76a is a small bug-fix release to patch up problems with 1.76.
This changelog is brought to you by Batman and ramen.

=New Plugin File Features=
==Per-Map Plugin Files==
You can now have per-map plugin configuration files. AMX Mod X will automatically load any plugins listed in files having the following name: <tt>configs/maps/plugins-<map>.ini</tt>. Thus, <tt>de_dust</tt> specific plugins will be loaded from <tt>configs/maps/plugins-de_dust.ini</tt>.

Map-specific plugin files are parsed after the main plugins.ini is parsed, and after all secondary plugins-*.ini files are parsed in the <tt>configs</tt> folder. This means that a map-specific plugin listing inherits all settings above itself.

==Disabling Plugins==
A second feature was introduced to let users disable plugins per map. In any plugins-*.ini file, you may now add a "disabled" flag to a plugin name. This works like the "debug" flag. Example:
<code>
gaben.amxx disabled
</code>

This will block the plugin from being loaded from any other configuration file. So if <tt>plugins-de_dust.ini</tt> has the example line above, <tt>gaben.amxx</tt> will not be loaded from any other plugins file.

=New Scripting Features=
==Sorting==
AMX Mod X now has a comprehensive array sorting solution. You can sort using pre-defined array types, or use your own custom comparison functions. All of the sorting routines use the qsort() function from the C standard library, which is based on the [http://linux.wku.edu/~lamonml/algor/sort/quick.html Quick Sort] algorithm.

===Basic Sorting===
The follow basic sorting natives were added. These natives sort an array in-place using pre-defined comparison routines. You can change the sorting order using an optional third parameter. By default it is <tt>Sort_Ascending</tt>, and <tt>Sort_Descending</tt> is available as well.
*<tt>[http://www.amxmodx.org/funcwiki.php?go=func&id=1115 SortIntegers]()</tt> - Sorts an array of integers.
*<tt>[http://www.amxmodx.org/funcwiki.php?go=func&id=1116 SortFloats]()</tt> - Sorts an array of floats.
*<tt>[http://www.amxmodx.org/funcwiki.php?go=func&id=1117 SortStrings]()</tt> - Sorts an array of strings.

===Custom Sorting===
Furthermore, you can also define your own custom comparison functions and have the sorting algorithm run them for you. This can be useful in a variety of ways. For example, if you have an array of players and an array of those player's skills, you can easily sort the player ids by skill using this feature.

Custom sorting requires making a function which compares two elements of your array. Given elements e1 and e2:
*Return -1 to mean "e1 comes before e2"
*Return 0 to mean "e1 is equal to e2"
*Return 1 to mean "e1 comes after e2"
For example, a very simple formula to compare integers in this manner is: <tt>e1 - e2</tt>.

The custom sorting natives are:
*<tt>[http://www.amxmodx.org/funcwiki.php?go=func&id=1118 SortCustom1D]()</tt> - Sorts a 1D array given a custom comparison function.
*<tt>[http://www.amxmodx.org/funcwiki.php?go=func&id=1119 SortCustom2D]()</tt> - Sorts a 2D array given a custom comparison function.

===Examples===
You can see an example of each native listed above in the [http://svn.tcwonline.org/viewvc.cgi/trunk/plugins/testsuite/sorttest.sma?root=amxmodx&view=log sorting testing] plugin.

AMX Mod X 1.75 Scripting Changes

2006-11-11T22:48:08Z

MaximusBrood: Fixed dead link.

The AMX Mod X 1.75 release made important changes. While backwards compatibility was kept, intended functionality shifted in esoteric areas that will affect some plugins. Reading this article is highly recommended.

=Module Requirement Syusstem=
As part of the new Automatic Module Loading, the old <tt>#pragma library</tt> has been deprecated. You must now use:
<pawn>#pragma reqlib <library>
</pawn>
This means "require library". Plugins still compiled with <tt>#pragma library</tt> will still fail on load if the given module is not found. However, core will try to load each module given the rules below under "Automatic Module Loading".

=Auto Plugin Files=
With the introduction of callfunc and register_native, many people now distribute plugins in large sets. To make this easier on users, you can now distribute an "extended plugin file." For example, say you have five plugins in a set. Normally, you would have to ask the user to write each name into plugins.ini, like so:
<pre>
file1.amxx ;file1
file2.amxx ;file2
file3.amxx ;file3
file4.amxx ;file4
file5.amxx ;file5
</pre>

With AMX Mod X 1.75, any file in the configs folder which follows a certain name pattern will be auto-loaded as an additional plugins.ini file. The pattern is: plugins-*.ini.

For example, you could distribute <tt>plugins-carmod.ini</tt> as:
<pre>
;put a semi-colon to disable a plugin
cars_honda.amxx
cars_toyota.amxx
cars_ford.amxx
cars_bmw.amxx
cars_gaben.amxx
</pre>

This way, you can easily distribute an extractable install, rather than giving the user overcomplicated instructions. Furthermore, the file is easily disabled by simply modifying the name (for example, "disabled-carmod.ini").

=Automatic Module Loading=
==Overview==
As of AMX Mod X 1.75, there is a new, powerful automatic module loading system. That means that <tt>modules.ini</tt> is largely deprecated for general use. Instead, modules are loaded as plugins need them. This is done dynamically by core before plugins are even loaded, without the need to patch <tt>modules.ini</tt> and then change the map.

Modules can now define "Libraries" and "Library Classes". A library is a specific identifier that should match the filename of the module. For example, Engine's defined library is "engine". FakeMeta's library is "fakemeta", and so on.

A "library class" defines membership to a set of modules. For example, CSX has the library name "csx", but it is part of the library class "xstats". Library classes are also used for DBI and SQLX. This is very useful for being able to require one module type of any implementation.

==New API==
===Compiler Pragmas===
This is expanded with a number of new <tt>#pragma</tt> directives:
*<tt>#pragma reqlib <library></tt> - Requires that a given library must be loaded.
*<tt>#pragma reqclass <libclass></tt> - Requires that a given library class must be loaded.
*<tt>#pragma loadlib <library></tt> - Automatically attempts to load a given library (see more info below).
*<tt>#pragma expectlib <library1> <library2></tt> - If the first library is not loaded, the second one will be attempted to load (not very useful).
*<tt>#pragma expectclass <class> <library></tt> - If the expected class is not found, the given library will be attempted to load. This is useful for defining a default module to be loaded with a given class of modules.
*<tt>#pragma defclasslib <class> <library></tt> - Same as <tt>expectclass</tt>, however, <tt>defclasslib</tt> waits until all expectations are resolved. This lets plugins override defaults by adding their own expectations.

===Module Filtering===
The module_filter prototype now includes a second parameter, which tells you whether the requirement is a class or library.

Furthermore, module_exists has been deprecated for LibraryExists().

==How it Works==
The precise order of events is as follows:
*When the first entity is spawned, AMX Mod X loads all unloaded modules in <tt>modules.ini</tt>.
*After <tt>modules.ini</tt> is parsed, <tt>plugins.ini</tt> is read. Each file is mapped into a cache.
*The cache is previewed.
**First, the "library" table is read. This table is read for backwards compatibility with AMX Mod X 1.71 and prior. Each entry is read as a module file shortname, and the module is loaded if it exists.
**Next, the "pubtags" table is read. Each entry is decoded to one of the special #pragma commands.
***All loadlib commands are executed, and the modules loaded.
***All expect commands are executed.
***All defclasslib commands are executed.
*AMX Mod X then waits until ServerActivate is called.
*All plugins are loaded. If the plugin is in the cache, the cache is read instead. For each plugin...
**The library table is read. For each library that is both nonexistant and unhandled by a module filter, the plugin fails to load.
**The pubtags table is read. For each reqlib and reqclass entry that are both nonexistant and unhandled by a module filter, the plugin fails to load.
*The plugin cache is invalidated and the server is considered "loaded".

=SQLX=
==Introduction==
SQLX is a new Database API that supercedes DBI. Its main feature is that you can load two SQLX modules at once, whereas you cannot with DBI. It also supports threaded queries, which let you process data without interrupting gameplay from a bad network connection.

These additions come at a hefty price. The SQLX API is significantly more complex than DBI. Although some might find it easier to use due to its simpler error checking and iteration, it requires more manual memory management and has less simple abstraction. Furthermore, taking advantage of the new <tt>SQL_ThreadQuery</tt> native will require nothing short of a rewrite for most plugins, as it is ''asynchronous'' instead of ''synchronous''. Because of this, the new SQLX modules also implement the old DBI functionality, for both backwards compatibility and for plugin developers familiar with the old API. All three APIs - SQL-threaded, SQL-non-threaded, and DBI, are still fully supported.

==Usage==
Since SQLX is an expansive API, showing a single plugin of its usage would be difficult. It is highly recommended that users interested in the new API look at the [http://svn.tcwonline.org/viewvc.cgi/trunk/plugins/testsuite/sqlxtest.sma?root=amxmodx SQLxTest] plugin, which compares two different DBI methods and both SQL methods of querying a database. It is highly useful for both regression testing and for getting an idea of how the API works.

The most important concept of SQLX is "Handles," which are a precursor to a system planned for SourceMod. Handles are datatypes that store internal information that you should not modify. Whenever you create a handle, you must also free it, with <tt>SQL_FreeHandle</tt>().

==Native Overview==
The basic natives of SQLX are:
*<tt>SQL_MakeDbTuple</tt> (or simple stock version, <tt>SQL_MakeStdTuple</tt>) - This creates a variable that holds information about a database. It does not connect to the database. This is so you don't have to keep retrieving cvar info on every connection. You do not have to free these handles, although it is a good idea if you create them dynamically.
*<tt>SQL_Connect</tt> - Connects to a database and returns a new Handle, or <tt>Empty_Handle</tt> on failure.
*<tt>SQL_PrepareQuery</tt> - Prepares a query for execution, and returns a new Handle to the query.
*<tt>SQL_Execute</tt> - Executes a prepared query, and returns 0 on failure (1 on success).
*<tt>SQL_MoreResults</tt> - Returns 1 if there are more results in the query result queue, 0 if none.
*<tt>SQL_ReadResult</tt> - Reads the current row result by the column's numerical index, similar to dbi_field/dbi_result.
*<tt>SQL_NextRow</tt> - Advances to the next result row. '''Compatibility Warning''': This does not need to be called first! Unlike <tt>dbi_nextrow</tt>, the query is automatically at the first row. If you call <tt>SQL_NextRow</tt> before <tt>SQL_ReadResult</tt>, your are actually skipping a row.
*<tt>SQL_FreeHandle</tt> - Frees a Handle. You must do this or else memory will leak.
*<tt>SQL_ThreadQuery</tt> - Places a query and connection info into a threaded queue. In another thread, the connection is established, the query is executed, and the connection is dropped. The query results are then posted back into the main thread and given to the plugin on the next server-frame.
**Note that while powerful, the mechanism is very simplistic. Similar to <tt>set_task</tt>, you must differentiate multiple queries having the same callback by packing binary data into an array. Furthermore, you can only make one query at a time, since the queue is "push one, resolve one, pop one." If you plan on making five queries in a row in order to get aggregate information about a player, you must make each of these five queries in separate stages, and you must also take into account asynchronous factors such as the player dropping during the middle of a query. (One way to do this is to pack the player's authid and client index into the callback data and verify it when the query finishes.)
**Note that you should currently not call this native during <tt>plugin_end</tt>(). The backend threader freezes the query queue at this time and flushes all remaining queries back to the main thread. It is likely your plugin will simply deadlock (freeze idly). Even if this is corrected, there is no reason to use threaded queries in <tt>plugin_end</tt>() anyway, because all remaining threaded queries are executed as non-threaded before the mapchanges.

=New Natives / Native Changes=
==Register Message==
The <tt>register_message</tt> set of natives, including <tt>get/set_msg_block</tt>, has been moved to Core. This is to facilitate users who prefer to use FakeMeta, and like the simplicity and speed of using Engine's message interception functions.
 
This change is backwards compatible.

==Argument Formatting==
The <tt>format_args</tt> function is now replaced with a much faster, more compatible <tt>vformat</tt> function. Its usage is slightly different (read the include file, <tt>string.inc</tt>), but it accepts %L, whereas format_args does not. A quick example:
<pawn>debugprint(const fmt[], ...)
{
static temp[2048]
vformat(temp, sizeof(temp)-1, fmt, 2)
log_message("[DEBUG] %s", temp)
}</pawn>

==Other Core Natives==
*<tt>register_plugin</tt> - Now returns a plugin id.
*<tt>get_amxx_verstring</tt> - Returns the AMX Mod X version string.
*<tt>get_weaponid</tt> - Gets a weapon id from a weapon name.

==FakeMeta==
===New Natives===
*<tt>get_orig_retval</tt> - Gets the original return value of an engine or game DLL function.
*<tt>copy_infokey_buffer</tt> - Copies the given infobuffer pointer into output buffer.
*<tt>get/set_cd</tt> - Gets or sets members of a clientdata data structure (used with UpdateClientData).
*<tt>get/set_es</tt> - Gets or sets members of an entity_state data structure (used with AddToFullPack).
*<tt>get/set_uc</tt> - Gets or sets members of a usecmd data structure (used with CmdStart).

===New Engine/GameDLL Functions===
The <tt>register_forward</tt> native now allows for hooking a number of new functions from the engine or game DLL including:
*<tt>UpdateClientData</tt>
*<tt>AddToFullPack</tt>
*<tt>CmdStart</tt>
*<tt>CmdEnd</tt>
*<tt>CreateInstBaselines</tt> - Game DLL function
*<tt>CreateInstBaseline</tt> - Engine function
*<tt>CreateBaseline</tt>
*<tt>GetInfoKeyBuffer</tt>
*<tt>AlertMessage</tt> - This now can be called via <tt>engfunc</tt>
*<tt>ClientPrintf</tt>

These functions can also be called via <tt>engfunc</tt> or <tt>dllfunc</tt>.

===Breaking Changes===
Using <tt>engfunc</tt> in order to call <tt>EngFunc_InfoKeyValue</tt>, <tt>EngFunc_SetKeyValue</tt>, or <tt>EngFunc_SetClientKeyValue</tt> now requires passing an infobuffer pointer. An infobuffer pointer can be obtained by calling <tt>EngFunc_GetInfoKeyBuffer</tt>. For example:
<pawn>some_function(id, name[])
{
new infokey = engfunc(EngFunc_GetInfoKeyBuffer, id)
engfunc(EngFunc_SetClientKeyValue, id, infokey, "model", name)
}</pawn>

If you hook ClientUserInfoChanged via Fakemeta, an infobuffer pointer is now also forwarded to your function in addition to the client id.

==Cstrike==
*<tt>cs_get_user_mapzones</tt> - Returns bitwise flags of where on the map a player is located such as buy zone, bomb site, hostage rescue zone, VIP safety zone, and escape zone.
*<tt>cs_set_user_vip</tt> - Now takes two additional (but optional) parameters for determining whether or not the player model and scoreboard get updated.
*<tt>cs_set_user_zoom</tt> - Sets a zooming type on a player for any weapon.
*<tt>cs_get_user_zoom</tt> - Returns the zooming type of a player.

==DoD==
===Forwards===
*<tt>dod_client_changeteam(id, team, oldteam)</tt> - This Forward is called when a player changes team, it contains the player id, the new team they have joined and the old team they were on.
*<tt>dod_client_changeclass(id, class, oldclass)</tt> - This Forward is called just after player spawns if a player changes class, it contains the player id, the new class number and the old class number.
*<tt>dod_client_spawn(id)</tt> - This Forward is called when a player spawns, it contains the player id.

===Stocks===
*<tt>dod_set_model(id, model[])</tt> - Sets the model for a player, good for if you want to have special models. The models used MUST be located in the following directory: dod/models/player/ And should look something like this: dod/models/player/models-name/model-name.mdl dod/models/player/models-name/model-nameT.mdl
*<tt>dod_set_body_number(id, bodynumber)</tt> - Sets the model number for a players model
*<tt>dod_clear_model(id)</tt> - Turns off the special model for a player

==New Stocks==
===Engine===
*<tt>IsInWorld</tt> - Checks if an entity is within the bounds of the world (from HLSDK).

===FakeMeta===
*<tt>DF_UpdateClientData</tt> - Calls UpdateClientData game DLL function.
*<tt>DF_AddToFullPack</tt> - Calls AddToFullPack game DLL function.
*<tt>DF_CmdStart</tt> - Calls CmdStart game DLL function.
*<tt>DF_CmdEnd</tt> - Calls CmdEnd game DLL function.
*<tt>DF_CreateBaseline</tt> - Calls CreateBaseline game DLL function.
*<tt>DF_CreateInstBaselines</tt> - Calls CreateInstancedBaselines game DLL function.
*<tt>EF_CreateInstBaseline</tt> - Calls CreateInstancedBaseline engine function.
*<tt>EF_GetInfoKeyBuffer</tt> - Calls GetInfoKeyBuffer engine function.
*<tt>EF_ClientPrintf</tt> - Calls ClientPrintf engine function.

==New Constants==
Various sound constants (<tt>SND_SPAWNING</tt>, <tt>SND_STOP</tt>, <tt>SND_CHANGE_VOL</tt>, and <tt>SND_CHANGE_PITCH</tt>) from the HL SDK as well as a constant for pi were added to <tt>amxconst.inc</tt>. <tt>TE_*</tt> (temp entity) message constants have also been added which will automatically be included with <tt>#include <amxmodx></tt>. And finally, a new <tt>hlsdk_const.inc</tt> file has been added that contains many more constants from the SDK. This is automatically included with <tt>#include <engine></tt> or <tt>#include <fakemeta></tt>.

=Module API=
The AMX Mod X module API received a small overhaul for 1.75.

==Versioning/Interface Additions==
The internal module interface version is 4. However, modules from M/SDK 3 will still load.

M/SDK Version 4 modules have two new members of public information: the library string, and the library class string. These contain comma delimited names of whatever libraries or library classes the module would like to be registered.

For backwards compatibility, M/SDK Version 4 modules have an automatically empty library class string, and a library string equal to the logtag string.

==New Callbacks==
Modules can now be informed of when plugins are about to be unloaded, and when plugins have been fully unloaded. This means that modules don't have to hook ServerActivate and ServerActivate_Post (implementation dependent), don't need to be loaded by Metamod, and don't need to detach simply to release resources.

==New Functions==
*<tt>MF_GetLocalInfo</tt> - Intended for modules using LOCALINFO, which required a Metamod attachment. This is equal to AMX Mod X's core function <tt>get_localinfo</tt>.
*<tt>MF_OverrideNatives</tt> - Given a native list, this specifies that any other module already providing these natives will no longer provide them. This was added to force backwards compatibility between SQLITE and MySQLX. Usage is not recommended.
*<tt>MF_FindLibrary</tt> - Essentially the same function as LibraryExists() for plugins.
*<tt>MF_AddLibraries</tt> - Adds a comma delimited list of libraries or library classes. You must specify a "parent" pointer that identifies the module. This is easily accomplished by taking the address of any static variable.
*<tt>MF_RemoveLibraries</tt> - Removes all library entries with the given parent pointer. This is useful if your module adds custom entries not in its defined list.

==MSVC8 Compatibility==
M/SDK Version 4 now contains preprocessor definitions for compatibility with Microsoft's Visual Studio 2005/8.0 (provided by [[User:Damaged Soul|Damaged Soul]]). These macros can be turned off in the <tt>moduleconfig.h</tt> file by uncommenting the definition of <tt>NO_MSVC8_AUTO_COMPAT</tt>.

=Minor Changes=
==Compiler Defines==
Since <tt>__DATE__</tt> was fixed in 1.75, the macro <tt>__TIME__</tt> was also added.

AMX Mod X 1.75 Scripting Changes

2006-11-11T22:41:15Z

MaximusBrood:

The AMX Mod X 1.75 release made important changes. While backwards compatibility was kept, intended functionality shifted in esoteric areas that will affect some plugins. Reading this article is highly recommended.

=Module Requirement System=
As part of the new Automatic Module Loading, the old <tt>#pragma library</tt> has been deprecated. You must now use:
<pawn>#pragma reqlib <library>
</pawn>
This means "require library". Plugins still compiled with <tt>#pragma library</tt> will still fail on load if the given module is not found. However, core will try to load each module given the rules below under "Automatic Module Loading".

=Auto Plugin Files=
With the introduction of callfunc and register_native, many people now distribute plugins in large sets. To make this easier on users, you can now distribute an "extended plugin file." For example, say you have five plugins in a set. Normally, you would have to ask the user to write each name into plugins.ini, like so:
<pre>
file1.amxx ;file1
file2.amxx ;file2
file3.amxx ;file3
file4.amxx ;file4
file5.amxx ;file5
</pre>

With AMX Mod X 1.75, any file in the configs folder which follows a certain name pattern will be auto-loaded as an additional plugins.ini file. The pattern is: plugins-*.ini.

For example, you could distribute <tt>plugins-carmod.ini</tt> as:
<pre>
;put a semi-colon to disable a plugin
cars_honda.amxx
cars_toyota.amxx
cars_ford.amxx
cars_bmw.amxx
cars_gaben.amxx
</pre>

This way, you can easily distribute an extractable install, rather than giving the user overcomplicated instructions. Furthermore, the file is easily disabled by simply modifying the name (for example, "disabled-carmod.ini").

=Automatic Module Loading=
==Overview==
As of AMX Mod X 1.75, there is a new, powerful automatic module loading system. That means that <tt>modules.ini</tt> is largely deprecated for general use. Instead, modules are loaded as plugins need them. This is done dynamically by core before plugins are even loaded, without the need to patch <tt>modules.ini</tt> and then change the map.

Modules can now define "Libraries" and "Library Classes". A library is a specific identifier that should match the filename of the module. For example, Engine's defined library is "engine". FakeMeta's library is "fakemeta", and so on.

A "library class" defines membership to a set of modules. For example, CSX has the library name "csx", but it is part of the library class "xstats". Library classes are also used for DBI and SQLX. This is very useful for being able to require one module type of any implementation.

==New API==
===Compiler Pragmas===
This is expanded with a number of new <tt>#pragma</tt> directives:
*<tt>#pragma reqlib <library></tt> - Requires that a given library must be loaded.
*<tt>#pragma reqclass <libclass></tt> - Requires that a given library class must be loaded.
*<tt>#pragma loadlib <library></tt> - Automatically attempts to load a given library (see more info below).
*<tt>#pragma expectlib <library1> <library2></tt> - If the first library is not loaded, the second one will be attempted to load (not very useful).
*<tt>#pragma expectclass <class> <library></tt> - If the expected class is not found, the given library will be attempted to load. This is useful for defining a default module to be loaded with a given class of modules.
*<tt>#pragma defclasslib <class> <library></tt> - Same as <tt>expectclass</tt>, however, <tt>defclasslib</tt> waits until all expectations are resolved. This lets plugins override defaults by adding their own expectations.

===Module Filtering===
The module_filter prototype now includes a second parameter, which tells you whether the requirement is a class or library.

Furthermore, module_exists has been deprecated for LibraryExists().

==How it Works==
The precise order of events is as follows:
*When the first entity is spawned, AMX Mod X loads all unloaded modules in <tt>modules.ini</tt>.
*After <tt>modules.ini</tt> is parsed, <tt>plugins.ini</tt> is read. Each file is mapped into a cache.
*The cache is previewed.
**First, the "library" table is read. This table is read for backwards compatibility with AMX Mod X 1.71 and prior. Each entry is read as a module file shortname, and the module is loaded if it exists.
**Next, the "pubtags" table is read. Each entry is decoded to one of the special #pragma commands.
***All loadlib commands are executed, and the modules loaded.
***All expect commands are executed.
***All defclasslib commands are executed.
*AMX Mod X then waits until ServerActivate is called.
*All plugins are loaded. If the plugin is in the cache, the cache is read instead. For each plugin...
**The library table is read. For each library that is both nonexistant and unhandled by a module filter, the plugin fails to load.
**The pubtags table is read. For each reqlib and reqclass entry that are both nonexistant and unhandled by a module filter, the plugin fails to load.
*The plugin cache is invalidated and the server is considered "loaded".

=SQLX=
==Introduction==
SQLX is a new Database API that supercedes DBI. Its main feature is that you can load two SQLX modules at once, whereas you cannot with DBI. It also supports threaded queries, which let you process data without interrupting gameplay from a bad network connection.

These additions come at a hefty price. The SQLX API is significantly more complex than DBI. Although some might find it easier to use due to its simpler error checking and iteration, it requires more manual memory management and has less simple abstraction. Furthermore, taking advantage of the new <tt>SQL_ThreadQuery</tt> native will require nothing short of a rewrite for most plugins, as it is ''asynchronous'' instead of ''synchronous''. Because of this, the new SQLX modules also implement the old DBI functionality, for both backwards compatibility and for plugin developers familiar with the old API. All three APIs - SQL-threaded, SQL-non-threaded, and DBI, are still fully supported.

==Usage==
Since SQLX is an expansive API, showing a single plugin of its usage would be difficult. It is highly recommended that users interested in the new API look at the [http://cvs.tcwonline.org/viewvc.cgi/amxmodx/plugins/testsuite/sqlxtest.sma?view=log SQLxTest] plugin, which compares two different DBI methods and both SQL methods of querying a database. It is highly useful for both regression testing and for getting an idea of how the API works.

The most important concept of SQLX is "Handles," which are a precursor to a system planned for SourceMod. Handles are datatypes that store internal information that you should not modify. Whenever you create a handle, you must also free it, with <tt>SQL_FreeHandle</tt>().

==Native Overview==
The basic natives of SQLX are:
*<tt>SQL_MakeDbTuple</tt> (or simple stock version, <tt>SQL_MakeStdTuple</tt>) - This creates a variable that holds information about a database. It does not connect to the database. This is so you don't have to keep retrieving cvar info on every connection. You do not have to free these handles, although it is a good idea if you create them dynamically.
*<tt>SQL_Connect</tt> - Connects to a database and returns a new Handle, or <tt>Empty_Handle</tt> on failure.
*<tt>SQL_PrepareQuery</tt> - Prepares a query for execution, and returns a new Handle to the query.
*<tt>SQL_Execute</tt> - Executes a prepared query, and returns 0 on failure (1 on success).
*<tt>SQL_MoreResults</tt> - Returns 1 if there are more results in the query result queue, 0 if none.
*<tt>SQL_ReadResult</tt> - Reads the current row result by the column's numerical index, similar to dbi_field/dbi_result.
*<tt>SQL_NextRow</tt> - Advances to the next result row. '''Compatibility Warning''': This does not need to be called first! Unlike <tt>dbi_nextrow</tt>, the query is automatically at the first row. If you call <tt>SQL_NextRow</tt> before <tt>SQL_ReadResult</tt>, your are actually skipping a row.
*<tt>SQL_FreeHandle</tt> - Frees a Handle. You must do this or else memory will leak.
*<tt>SQL_ThreadQuery</tt> - Places a query and connection info into a threaded queue. In another thread, the connection is established, the query is executed, and the connection is dropped. The query results are then posted back into the main thread and given to the plugin on the next server-frame.
**Note that while powerful, the mechanism is very simplistic. Similar to <tt>set_task</tt>, you must differentiate multiple queries having the same callback by packing binary data into an array. Furthermore, you can only make one query at a time, since the queue is "push one, resolve one, pop one." If you plan on making five queries in a row in order to get aggregate information about a player, you must make each of these five queries in separate stages, and you must also take into account asynchronous factors such as the player dropping during the middle of a query. (One way to do this is to pack the player's authid and client index into the callback data and verify it when the query finishes.)
**Note that you should currently not call this native during <tt>plugin_end</tt>(). The backend threader freezes the query queue at this time and flushes all remaining queries back to the main thread. It is likely your plugin will simply deadlock (freeze idly). Even if this is corrected, there is no reason to use threaded queries in <tt>plugin_end</tt>() anyway, because all remaining threaded queries are executed as non-threaded before the mapchanges.

=New Natives / Native Changes=
==Register Message==
The <tt>register_message</tt> set of natives, including <tt>get/set_msg_block</tt>, has been moved to Core. This is to facilitate users who prefer to use FakeMeta, and like the simplicity and speed of using Engine's message interception functions.
 
This change is backwards compatible.

==Argument Formatting==
The <tt>format_args</tt> function is now replaced with a much faster, more compatible <tt>vformat</tt> function. Its usage is slightly different (read the include file, <tt>string.inc</tt>), but it accepts %L, whereas format_args does not. A quick example:
<pawn>debugprint(const fmt[], ...)
{
static temp[2048]
vformat(temp, sizeof(temp)-1, fmt, 2)
log_message("[DEBUG] %s", temp)
}</pawn>

==Other Core Natives==
*<tt>register_plugin</tt> - Now returns a plugin id.
*<tt>get_amxx_verstring</tt> - Returns the AMX Mod X version string.
*<tt>get_weaponid</tt> - Gets a weapon id from a weapon name.

==FakeMeta==
===New Natives===
*<tt>get_orig_retval</tt> - Gets the original return value of an engine or game DLL function.
*<tt>copy_infokey_buffer</tt> - Copies the given infobuffer pointer into output buffer.
*<tt>get/set_cd</tt> - Gets or sets members of a clientdata data structure (used with UpdateClientData).
*<tt>get/set_es</tt> - Gets or sets members of an entity_state data structure (used with AddToFullPack).
*<tt>get/set_uc</tt> - Gets or sets members of a usecmd data structure (used with CmdStart).

===New Engine/GameDLL Functions===
The <tt>register_forward</tt> native now allows for hooking a number of new functions from the engine or game DLL including:
*<tt>UpdateClientData</tt>
*<tt>AddToFullPack</tt>
*<tt>CmdStart</tt>
*<tt>CmdEnd</tt>
*<tt>CreateInstBaselines</tt> - Game DLL function
*<tt>CreateInstBaseline</tt> - Engine function
*<tt>CreateBaseline</tt>
*<tt>GetInfoKeyBuffer</tt>
*<tt>AlertMessage</tt> - This now can be called via <tt>engfunc</tt>
*<tt>ClientPrintf</tt>

These functions can also be called via <tt>engfunc</tt> or <tt>dllfunc</tt>.

===Breaking Changes===
Using <tt>engfunc</tt> in order to call <tt>EngFunc_InfoKeyValue</tt>, <tt>EngFunc_SetKeyValue</tt>, or <tt>EngFunc_SetClientKeyValue</tt> now requires passing an infobuffer pointer. An infobuffer pointer can be obtained by calling <tt>EngFunc_GetInfoKeyBuffer</tt>. For example:
<pawn>some_function(id, name[])
{
new infokey = engfunc(EngFunc_GetInfoKeyBuffer, id)
engfunc(EngFunc_SetClientKeyValue, id, infokey, "model", name)
}</pawn>

If you hook ClientUserInfoChanged via Fakemeta, an infobuffer pointer is now also forwarded to your function in addition to the client id.

==Cstrike==
*<tt>cs_get_user_mapzones</tt> - Returns bitwise flags of where on the map a player is located such as buy zone, bomb site, hostage rescue zone, VIP safety zone, and escape zone.
*<tt>cs_set_user_vip</tt> - Now takes two additional (but optional) parameters for determining whether or not the player model and scoreboard get updated.
*<tt>cs_set_user_zoom</tt> - Sets a zooming type on a player for any weapon.
*<tt>cs_get_user_zoom</tt> - Returns the zooming type of a player.

==DoD==
===Forwards===
*<tt>dod_client_changeteam(id, team, oldteam)</tt> - This Forward is called when a player changes team, it contains the player id, the new team they have joined and the old team they were on.
*<tt>dod_client_changeclass(id, class, oldclass)</tt> - This Forward is called just after player spawns if a player changes class, it contains the player id, the new class number and the old class number.
*<tt>dod_client_spawn(id)</tt> - This Forward is called when a player spawns, it contains the player id.

===Stocks===
*<tt>dod_set_model(id, model[])</tt> - Sets the model for a player, good for if you want to have special models. The models used MUST be located in the following directory: dod/models/player/ And should look something like this: dod/models/player/models-name/model-name.mdl dod/models/player/models-name/model-nameT.mdl
*<tt>dod_set_body_number(id, bodynumber)</tt> - Sets the model number for a players model
*<tt>dod_clear_model(id)</tt> - Turns off the special model for a player

==New Stocks==
===Engine===
*<tt>IsInWorld</tt> - Checks if an entity is within the bounds of the world (from HLSDK).

===FakeMeta===
*<tt>DF_UpdateClientData</tt> - Calls UpdateClientData game DLL function.
*<tt>DF_AddToFullPack</tt> - Calls AddToFullPack game DLL function.
*<tt>DF_CmdStart</tt> - Calls CmdStart game DLL function.
*<tt>DF_CmdEnd</tt> - Calls CmdEnd game DLL function.
*<tt>DF_CreateBaseline</tt> - Calls CreateBaseline game DLL function.
*<tt>DF_CreateInstBaselines</tt> - Calls CreateInstancedBaselines game DLL function.
*<tt>EF_CreateInstBaseline</tt> - Calls CreateInstancedBaseline engine function.
*<tt>EF_GetInfoKeyBuffer</tt> - Calls GetInfoKeyBuffer engine function.
*<tt>EF_ClientPrintf</tt> - Calls ClientPrintf engine function.

==New Constants==
Various sound constants (<tt>SND_SPAWNING</tt>, <tt>SND_STOP</tt>, <tt>SND_CHANGE_VOL</tt>, and <tt>SND_CHANGE_PITCH</tt>) from the HL SDK as well as a constant for pi were added to <tt>amxconst.inc</tt>. <tt>TE_*</tt> (temp entity) message constants have also been added which will automatically be included with <tt>#include <amxmodx></tt>. And finally, a new <tt>hlsdk_const.inc</tt> file has been added that contains many more constants from the SDK. This is automatically included with <tt>#include <engine></tt> or <tt>#include <fakemeta></tt>.

=Module API=
The AMX Mod X module API received a small overhaul for 1.75.

==Versioning/Interface Additions==
The internal module interface version is 4. However, modules from M/SDK 3 will still load.

M/SDK Version 4 modules have two new members of public information: the library string, and the library class string. These contain comma delimited names of whatever libraries or library classes the module would like to be registered.

For backwards compatibility, M/SDK Version 4 modules have an automatically empty library class string, and a library string equal to the logtag string.

==New Callbacks==
Modules can now be informed of when plugins are about to be unloaded, and when plugins have been fully unloaded. This means that modules don't have to hook ServerActivate and ServerActivate_Post (implementation dependent), don't need to be loaded by Metamod, and don't need to detach simply to release resources.

==New Functions==
*<tt>MF_GetLocalInfo</tt> - Intended for modules using LOCALINFO, which required a Metamod attachment. This is equal to AMX Mod X's core function <tt>get_localinfo</tt>.
*<tt>MF_OverrideNatives</tt> - Given a native list, this specifies that any other module already providing these natives will no longer provide them. This was added to force backwards compatibility between SQLITE and MySQLX. Usage is not recommended.
*<tt>MF_FindLibrary</tt> - Essentially the same function as LibraryExists() for plugins.
*<tt>MF_AddLibraries</tt> - Adds a comma delimited list of libraries or library classes. You must specify a "parent" pointer that identifies the module. This is easily accomplished by taking the address of any static variable.
*<tt>MF_RemoveLibraries</tt> - Removes all library entries with the given parent pointer. This is useful if your module adds custom entries not in its defined list.

==MSVC8 Compatibility==
M/SDK Version 4 now contains preprocessor definitions for compatibility with Microsoft's Visual Studio 2005/8.0 (provided by [[User:Damaged Soul|Damaged Soul]]). These macros can be turned off in the <tt>moduleconfig.h</tt> file by uncommenting the definition of <tt>NO_MSVC8_AUTO_COMPAT</tt>.

=Minor Changes=
==Compiler Defines==
Since <tt>__DATE__</tt> was fixed in 1.75, the macro <tt>__TIME__</tt> was also added.
