How to hook a function?

[BBB]

Can someone give me an example of hooking the "GameTextForPlayer"-function? I would like to get the content of its pushed parameters.

}

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
    new string[128];
    format(string, sizeof(string), "You are entering vehicle %i",vehicleid);
    SendClientMessage(playerid, 0xFFFFFFFF, string);
    return 1;

you can easily do that with or without sobeit....

char *text; //set your text.... like: "~r~imma 1337 nigger~w~!" 
int time; //time to show the text(in ms)... like: 1000ms(1sec)
int textsize; //size... like: 5 for example

uint32_t DoneAddr = g_dwSAMP_Addr/*BaseAddress*/ + 0x63F00/*0.3xR1*/;
__asm 
{
push textsize
push time
push text
call DoneAddr
}

in case you don't do it in sobeit, you just gonna have to set the base address of samp dll module by yourself(easy stuff).

...and in case you need such thing for other game(not GTA:SA:MP), its totaly different(i'm saying that because i'm sure that someone gonna try it ).

maybe I wasn't clear enough
by hooking I mean intercepting the function call and change it's behavior
using this I can change the parameters, or just do nothing etc.

i'm sure you wasn't clear enough(at least to me)... :| :|:|

this function basically is going to add the "game text" in your screen(according to the custom params that you gonna use before call it).
(you can trace the memory address in debuger to see by yourself... ).
here... look:

look at the address:

now going to the second call("01DC3BA1"):

the function(as a sample):

P.S.:
here is my base address: http://puu.sh/3dG2o.png

anyway... you said that you already solved.
(so nvm, just forget that this thread existed).
