Engine Chams

[iHakk]

I've got a little problem with engine chams.
If I start CS:S and join/create a server, everything works fine. But as soon as I leave the server and join/create another one, CS:S crashes.
Does anybody have a solution for this?

?dit:
I setup the hook in HudUpdate, whether it's necessary or not.

if(g_pModelRender)
		{
			gDrawModelEx.Hook((DWORD)&new_DrawModelEx,(PDWORD)g_pModelRender,19);
			_log->con("DrawModelEx Hooked: 0x%.8X",gDrawModelEx.FunctionAddress());
		}

normally you hook it once and only not on each frame.
wait for lawgiver or avitamin to reply for more info incase u did it correctly.

Exactly, no need to call it every frame. Now you are checking if( g_pModelRender ) and if everything works as should it's true all the time and hook + logging get's called all the time. You should call it at your main hooking function (the one that is one parameter of CreateThread in DLLMain ).

What i mean:

DWORD WINAPI Hookenz( LPVOID lpArgs )
{
   // do stuff
   gDrawModelEx.Hook((DWORD)&new_DrawModelEx,(PDWORD)g_pModelRender,19);
}

DLLMain:

CreateThread( NULL, NULL, (LPTHREAD_START_ROUTINE)&Hookenz , NULL, NULL, NULL);

[iHakk]

I call it in HudUpdate only once, like the console output so I can check all functions have been hooked correctly.

#define DO_ONCE( func )\
	static bool once= false;\
	if( once == false ) \
{\
	once = true;\
	func\
}

so all functions are just called once when everything is initialized.

€dit:
I thought about that what mencore said and created a class for hooking a function with another class (if I said it right) and hook DrawModelEx where I hook g_pModelRender:

. . .
	{
		g_pModelRender = (IVModelRender*)EngineFactory(VENGINE_HUDMODEL_INTERFACE_VERSION, NULL);//VENGINE_HUDMODEL_INTERFACE_VERSION
		_log->con( "g_pModelRender: [0x%.8X]", (DWORD)g_pModelRender);	
		hook.DrawModelX.Hook((DWORD)&new_DrawModelEx,(PDWORD)g_pModelRender,19);
		_log->con("DrawModelEx Hooked: 0x%.8X",hook.DrawModelX.FunctionAddress());
	}
. . .

but still crashing when I try to create another server.

Uh, why can't you fix things yourself? Debug, it isn't difficult...

[iHakk]

d?j?-vu.
I just asked if someone does know how to fix it/why the crash appears. It's completely the same code as aVitamin posted, I just changed the offsets to ->GetHealth() and ->GetTeamNumber() because I like the way w/o offsets.

EDIT: I looked at your source and decided against helping you.

uhm. okay. I didn't know I posted my Source code anywhere.

[badsta]

Well that epically failed, ok I am a retard. But basically what I was going to say was, make sure you only change the materials whilst ingame. Also I believe you only need to edit them once per load.

I got you mixed up with somebody else, my bad...

[iHakk]

I can load the textures and apply them on the players.
but if I uncomment this

//if(g_pTextureGreen->GetMaterialVarFlag(MATERIAL_VAR_IGNOREZ) == FALSE)
//	g_pTextureGreen->SetMaterialVarFlag(MATERIAL_VAR_IGNOREZ, TRUE);

or

pTexture = g_pTextureRed;
pWallHackTexture = g_pTextureYellow;
//pWallHackTexture->SetMaterialVarFlag(MATERIAL_VAR_IGNOREZ,true);

just for example, it instantly crashes. any ideas?
