Hooking CallBack(s) - How to Hook any callback

Hello all,
This tutorial is about hooking callback(s)-(any).

Let's start with simple example of OnFIlterScriptInit hook:

Код:

public OnFilterScriptInit()
{
	CallLocalFunction("RL@_OnFilterScriptInit", "");
	//Your code here!
}
#if defined _ALS_OnFilterScriptInit
	#undef OnFilterScriptInit
#else
	#define _ALS_OnFilterScriptInit
#endif
#define OnFilterScriptInit RL@_OnFilterScriptInit
forward RL@_OnFilterScriptInit();

First we need to call the public that we want no hook:

Код:

public OnFilterScriptInit()
{
	
}

Next we need to add this code to hook the callback:

Код:

#if defined _ALS_OnFilterScriptInit
	#undef OnFilterScriptInit
#else
	#define _ALS_OnFilterScriptInit
#endif
#define OnFilterScriptInit PRE_OnFilterScriptInit

And the last step, we need to forward the hook callbcack:

Код:

forward PRE_ OnFilterScriptInit();

Now, when OnFilterScript will called the hook public wiil called to.

Enjoy!
