Hello! I'm very new to sourcemod and just passed through these tutorials:

https://wiki.alliedmods.net/Introduc...rceMod_Plugins
https://wiki.alliedmods.net/Writing_Extensions

However, I still have some questions which I did not find answers to.

Code from the tutorial (extension.cpp):

PHP Code:

#include "extension.h"

/**
 * @file extension.cpp
 * @brief Implement extension code here.
 */

FirstExtension g_FirstExtension;        /**< Global singleton for extension's main interface */

SMEXT_LINK(&g_FirstExtension);

IForward *g_pSayChat = NULL;

cell_t SquareNumber(IPluginContext *pContext, const cell_t *params)
{
    cell_t number = params[1];
    return number * number;
}

const sp_nativeinfo_t MyNatives[] =
{
    { "SquareNumber",    SquareNumber },
    { NULL,            NULL },
};

void FirstExtension::SDK_OnAllLoaded()
{
    sharesys->AddNatives(myself, MyNatives);
    g_pSayChat = forwards->CreateForward("OnPlayerSayChat", ET_Event, 2, NULL, Param_Cell, Param_String);
}

void FirstExtension::SDK_OnUnload()
{
    forwards->ReleaseForward(g_pSayChat);
}

/** Fires the say chat event in plugins.  Returns true to allow the text, false to block. */
bool FireChatEvent(int client, const char *text)
{
    if (!g_pSayChat)
    {
        return true;
    }

    cell_t result = 0;
    g_pSayChat->PushCell(client);
    g_pSayChat->PushString(text);
    g_pSayChat->Execute(&result);

    if (result == Pl_Handled)
    {
        return false;
    }

    return true;
} 


I don't understand, when exactly FireChatEvent gets called?

I tried to include this simple extension in tutorial plugin's code:
first_ext.inc:

PHP Code:

#if defined _firstext_included
#endinput
#endif
#define _firstext_included

/**
 * Returns the square of a number.
 *
 * @param num    Number to square.
 * @return    The square of num.
 */
native int SquareNumber(num);


/**
* @brief Called whenever a client says something in chat.
*
* @param client    Index of the client.
* @param text        String containing the say text.
* @return         Plugin_Handled to block text from printing, Plugin_Continue otherwise.
*/
forward Action OnPlayerSayChat(int client, const char[] text);

/**
 * Do not edit below this line!
 */
public Extension:__ext_firstext = 
{
    name = "First extension",
    file = "first.ext.2.csgo",
#if defined AUTOLOAD_EXTENSIONS
    autoload = 1,
#else
    autoload = 0,
#endif
#if defined REQUIRE_EXTENSIONS
    required = 1,
#else
    required = 0,
#endif
}; 


helloworld.sp:

PHP Code:

#include <sourcemod>
#include <sdktools>
#include <first_ext>

public Plugin myinfo =
{
    name = "My First Plugin",
    author = "Me",
    description = "My first plugin ever",
    version = "1.0",
    url = "http://www.sourcemod.net/"
};

ConVar g_cvarMySlapDamage = null;

public void OnPluginStart()
{
    PrintToServer("Hello world!");
    RegAdminCmd("sm_myslap", Command_MySlap, ADMFLAG_SLAY);
    
    g_cvarMySlapDamage = CreateConVar("sm_myslap_damage", "1", "Default slap damage");
    AutoExecConfig(true, "plugin_myslap");
    
    LoadTranslations("common.phrases.txt"); // Required for FindTarget fail reply
}
 
public Action OnPlayerSayChat(int client, const char[] text)
{
    PrintToChat(client, "[SM] %d", SquareNumber(5)); 
    return Plugin_Continue;
} 


REQUIRE_EXTENSIONS is defined in core.inc and my plugin loads successfully so I assume that the extension is also loaded. However, when I say something in chat I don't get "[SM] 25" printed as I expected.

So, either `OnPlayerSayChat` is never fired (in that case, what sould I do to actually get it working?) or it is fired and I just made some mistakes so I don't get expected result. If latter, what are these mistakes and how to fix them?

Thanks!
