Fullbright with inline ASM

Hello guys

I have a problem... since a few days i play with ASM and i try to make a simple Fullbright cheat with inline ASM. (with dll injection)

But mw3 crash everytime when i inject the .dll.

My Code:

Code:

#include "stdafx.h"
#include <Windows.h>


void Fullbright(){
	DWORD dwFullbright = 0x06098CEC; 

	__asm{
		PUSH 0
			CALL [dwFullbright]
		MOV ESP, 9

	}

}
DWORD WINAPI Init(LPVOID unused)
{
   
    Fullbright();

}

BOOL WINAPI DllMain(HINSTANCE mod, DWORD DWORD_INITALIZE, LPVOID res)
{
    switch(DWORD_INITALIZE)
    {
    case DLL_PROCESS_ATTACH:  
        CreateThread(0, 0, &Init , 0, 0, 0); 

		 MessageBoxA(0, "Fullbright enabled", "Gangnamstyle is shit",0); 

        break;
     
     case DLL_PROCESS_DETACH:
 
                             MessageBoxA(0, "Fullbright disabled", "Gangnamstyle is very shit",0); 

        break;
    }
    return TRUE;
}

It would be nice if someone can tell me what i do wrong

.

Thanks.

Is that how you create a thread? I think that may be incorrect...
CreateThread(0, 0, (LPTHREAD_START_ROUTINE)Init, 0, 0, 0);

And try testing it without the breaks.

The create thread isn't the problem... I think :P

I'm not really good with asm, but I think "MOV dwFullBright, 4" should work.

Code:

void Fullbright(){
	DWORD dwFullbright = 0x06098CEC; 

        __asm MOV dwFullbright, 4

}

Thanks for the answers

with:

Code:

DWORD dwFullbright = 0x06098CEC; 

	__asm{
			
		MOV dwFullbright, 9

	}

mw3 don´t crash, but the fullbright doesn´t work :/.

I dont know why...

cheers

9 is the default value...

Write 4 for FullBright

Ohh i fail

Yeah thats right, but even when i write 4 it doesn´t work :O.

cheers

Got it to work(on 4D1) with:

Code:

void Loop(){
	DWORD Fb = 0x5F9690C;
	while(true){
		__asm MOV EAX, Fb
		__asm MOV DWORD PTR[EAX], 4
		Sleep(1000);
	}
}

Just change the offset :P

Pushes / calls you only use when you are using a FUNCTION
For an address simply use MOV as the guy up here said...
Although this doesn't help simplifying your code a thing since it will probably be compiled as a tbyte

Code:

B8 09 00 00 00; MOV EAX, 9
A3 EC 8C 09 06; MOV DWORD PTR DS[06098CEC], EAX

So nothing different.

Though nice that somebody finally takes up real coding challenges instead of making trainers all time with jorndel's class

Thank you very much Insane & Anonymouss =)

cheers :P

You don't need to use inline asm... You're only making it more complicated just to set a value inside an array... You could just use this (offsets for 1.9.453):

Code:

DWORD* mapLighting = (DWORD*)0x06098CEC;

void EnableFullbright()
{
    mapLighting[0] = 4;
    mapLighting[1] = 2; // Bonus: disables fog
}

void ResetLighting()
{
    mapLighting[0] = 9;
    mapLighting[1] = 5;
}

Credits to BaberZz and CoMPStR. I only updated the address.

Pretty sure he knows that... he's just "practicing" his asm, which is good

It's always better to not use asm, if he really needs to practice asm he should practice with something that he really needs to use it lol
