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!

Well since there is finally a tutorial about hooking
Can someone please tell me what does hooking mean?
What's the benefit of hooking a callback?

And why don't you use y_hooks it will save you from all the hassle anyways just hook TheCallback

and as ****** said this is not explained good, i think even you don't know what those codes do.

Really I didn't understand nothing from this tutorial and what you are talking about. What ALS and PRE mean?

The tutorial is not explained well.

Anyway, use y_hook its more faster than ALS.

Excuse me sir, but i did bother and searched, but i couldn't find exactly what does Hooking mean, i just found hooking methods without explaination.
If you can send me the tutorial through PM would be appreciated.

And I can't see any single reason to post it after a few users have already done that. :X
