 |
|
When i'm trying to put a script from CE to a inline asm in C++ it's working perfectly unless the script contains pointers. I take an example script I'm trying to use:
| Code: | _declspec(naked) void UnlimitedAttack()
{
__asm
{
push ebx
push eax
mov eax,[0x00804FD4]
mov ebx,[eax+0x5F4]
inc ebx
mov eax,[eax+0x14B4]
cmp eax, 0x50
pop eax
cmovge eax,ebx
pop ebx
mov [ebx],eax
mov edi,[ebp+0x10]
jmp dwUnlimitedAttackRet
}
} |
When this work properly it will move my char when the attack counter is at 80 (50 in hex) and then back again. But all this does when I activate it is to move me instantly and its like that until I turn it off. It gets like CSEAX X for those who played Maple. This script is working perfectly in CE but not here and I dont understand why :S. This only happens when there are pointers involved. My question is how to use pointers in inline asm, Any help is appreciated.

My assembler isnt that good, but I am quite sure you need to define dwUnlimitedAttackRet before you can use it.
Not sure about c++ inline, but i would try to define it like this
| Code: | _dwUnlimitedAttackRet:
push blah blah
mov your code here blah blah |

Here already has the DWORD define (DWORD dwUnlimitedAttackRet = . . .) or else it would give an error.

Then the jump should work as its unconditional as far as i can see... =/

C++ is a bit different than asm.
| Code: |
mov eax,[0x00804FD4]
mov eax,[eax]
mov ebx,[eax+0x5F4] |
will wwork.

| Code: |
mov eax,[0x00804FD4]
mov eax,[eax]
mov ebx,[eax+0x5F4] |
will wwork. |
Or just do
| Code: | mov eax,dword ptr ds:[0x00804FD4]
mov ebx,[eax+0x5F4] |

C++ is diffrent than ASM. 
The inline asm isn't. 
When you don't specify the size, the compiler ignores the brackets, it treats the opcode "mov reg32,val32" instead of "mov reg32,size seg:[val32]".
CE simply treat the value as the size of the register you're using, eax is a 32-bit register so it treats the value as a DWORD, you can simply write: "mov eax,dword ptr ds:[Address]", like smartz said.
