Call native functions, hook callbacks - IllidanS46 - 31.12.2010

Hello, can you help me how to call effectively native functions and hook callbacks (OnPlayerConnect) in plugin?

Re: Call native functions, hook callbacks - jaymac407 - 31.12.2010

To hook native functions, just put your plugins function inside the callback you want to hook, e.g.:

Code:

public OnGameModeInit()
{
	return NET_OnGameModeInit();
}

All functions are different, and you'll have to do some godmode reading through AMX and SA-MP SDK.

I found a way to call native function:
SetWeather(weather)

Code:

cell* params = (cell*)malloc(8);
params[0] = 4;
params[1] = 5; //weather 5
int idx;
amx_FindNative(amx, "SetWeather", &idx);
cell result;
amx_Callback(amx, idx, &result, params);
free(params);

When I first run it, weather has set to 5, but next time weather has set to 96 (0x60) and never more changed. Does anyone know where the problem is?

Ok, about hooking I know enough, but I still don't know how to correctly call native functions.
