[SAMP 0.3.7] Handy function for debugging...

[T3KTONIT]

hello, just found this function and its really helpful. i named it "DebugLog", anyways, its the internal debug/warning/error logger function that samp uses.

and it's the function responsible for printing the startup messages, the warnings(Warning: couldn't create vehicle type: %u), etc...

i figured i could share it with y'all so dat u can use it for debugging and stuff...

#define SAMP_CHAT_INFO_OFFSET     0x21A0E4
#define SAMP_FUNC_DEBUGLOG        0x64520


typedef int  (__cdecl    *__DebugLog)(void *g_Chat, char *log, ...);
__DebugLog DebugLog = (__DebugLog)(SAMP + SAMP_FUNC_DEBUGLOG);

//example usage :
void* g_Chat = (void*)*(DWORD*)(SAMP + SAMP_CHAT_INFO_OFFSET);
DebugLog(g_Chat, "This is a test %d %d %d  Hello ugbase!", 1, 2, 3);

Nice, here's the one for info messages, green text.
#define FUNC_INFOMSG 0x644A0

Sorry for writing here, but how get the pointer of chat message ?
(Like: "SAMP_INFO_OFFSET", "SAMP_CHAT_INFO_OFFSET")

i already defined SAMP_INFO_OFFSET...

you can find the offsets by disassembling samp.dll.

Oh Ok, Thanks, but i have problem with code (sorry if I'm bumbing like an idio..):

Don't define g_Chat as a global variable like that ...

do this :

void * g_Chat = NULL;
void Main(void)
{
 LoadSAMP();
 while (true)
 {
 if(!g_Chat)
 g_Chat = (void*)*(DWORD*)(g_dwSAMP_Addr + SAMP_CHAT_INFO_OFFSET);

  //AddClientMessage("WORKS?"); // NOT WORKS
  if(g_Chat)
  DebugLog(g_Chat, "WORKS?");
  Sleep(100);
 }
}

or better : (not tested)

#define g_Chat (void*)*(DWORD*)(SAMP + SAMP_CHAT_INFO_OFFSET);

main()
.
.
.
.
.
etc

EDIT: make a dll project ofcourse...

Spoiler

BOOL WINAPI DllMain(HMODULE hDll, DWORD dwReason, LPVOID lpReserved)
{

	DisableThreadLibraryCalls(hDll);

	if (dwReason == DLL_PROCESS_ATTACH)
	{
		CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)Main, NULL, NULL, NULL);
	}
	return TRUE;
}

nice try reviving code section, but now you get zombie  mg_run:

Doesn't Work

i would like to have that AddChatMessage "Trainer" too.
But mine is also not working..
