Castspellbyid Injektion

[hamburger12]

Hello i search an way to castspellbyid ... whitch ways are possible and what is wrong with my code =( this is the code:

#include <windows.h>

void __stdcall DllMain(_In_ unsigned int SpellId)
{
	DWORD CastSpellById = 0x007E59C0;
	__asm
	{
		push 0
		push 0
		push 0
		push 45284
		call CastSpellById
		add esp, 0x10
		retn
	}
}

Its C++ Dll code.. If i do something wrong correct me pleas! thank you.

I don't code in cpp, but I'm pretty sure that you are doing it wrong..

DllMain Callback Function (Windows)

oh boy....

[lanman92]

Did that actually compile? :O

Alright, I may be tired, but to me that code should work.

The only major problem is that You Must Never Do Complicated Stuff in DllMain.

Couple it with the TLS stuff and a beginthread call, and it just might work.

Edit: oops, don't retn from the inline assembly snippet. It's implied by the function ending scope, and may well screw up your stack.

1) Learn C++
2) Learn Assembly

What you've pasted is a smorgasbord of crap.

Well, the ASM-Code is correct.
Guess he copied it somewhere, he is even cleaning up the stack.

[Flowerew]

But since you don't really need asm-code for that it's even more retarded.

The fact he's even using ASM for this to begin with is retarded.

Hey I never said it was good code, or a good idea. Just that it should, in theory, work.

... Sounds like an argument for communism ;-)

Mh is there an way to cast spells via Memorywriting?

[Ryns]

hamburger12,

CastSpellById is a function call, you cannot do anything useful to it through memory-writing. You are vaguely on the right track though, an injected DLL is the best way to do this, but you are right at the beginning.

I suggest you search around the forums about EndScene hooking, this will enable to call game engine functions from Wow's main thread, if you ever want to use CastSpellById or CTM you will need to learn this ... to start with your DLLMain should look something like this:

#include <windows.h>
#include <stdio.h>


HRESULT __stdcall MyEndSceneHook(IDirect3DDevice9* pDevice)
{
   // Call game engine functions, CTM etc. with relative safety

   // Lastly we call the original EndScene function
   return originalEndScene(pDevice);
}


BOOL APIENTRY DllMain( HMODULE hModule, DWORD  ul_reason_for_call, LPVOID lpReserved )
{
   switch (ul_reason_for_call)
   {
      case DLL_PROCESS_ATTACH:
         {
            MessageBoxA(NULL,"Hello there, I have just been injected into this process!","Test",MB_OK);
            
            // Hook the DirectX EndScene here replacing it with MyEndSceneHook
            
            break;
         }
      case DLL_PROCESS_DETACH:
         {
            MessageBoxA(NULL,"Sorry, gtg now, byyyeee!","Test",MB_OK);

            // Unhook the DirectX EndScene here

            break;
         }
      case DLL_THREAD_ATTACH:
      case DLL_THREAD_DETACH:
         break;
   }
   return TRUE;
}

When you get to the point that you have hooked the EndScene correctly, you'll be able to call any of the game engine functions without the need for any ASM.
