 |
|
I changed the question:
CE:
| Code: | alloc(Apple,8)
alloc(begin,24)
begin:
mov [Apple+4], eax |
If I put that into C++, Apple wouldn't be defined, how would I define it?
I tried this, but DCed from game:
| Code: | void _declspec(naked) begin(void)
{
_asm
{
mov [Apple+4], eax
Apple:
}
} |

Why to change the question? Why not to post a reply with an another question?
The answer: new operator.

Look at the code:
| Code: | alloc(Apple,8)
alloc(begin,24)
begin:
mov [Apple+4], eax |
It allocates "begin" and "Apple" and makes changes at "begin", simply allocate memory and there make your changes. (mov [Apple+4], eax and whatever you need)
Jump from the address you want to code cave to that address you allocated and at the end of your code cave jump back. (look for a code caving tutorial, see how a code cave works)

I'm stuck at allocating memory for Apple  .
i'll just give the whole code out :\
| Code: | void _declspec(naked) CamVacON(void)
{
_asm
{
push edx
push ecx
mov edx,[0x00850460]
mov ecx,[edx+658]
cmp esi,ecx
je normal
mov [y], eax //eax = y
mov ecx,[edi-4]
mov [x], ecx //ecx = x
cmp [edx+380],6
je dotele
cmp [edx+380],2
je dotele
jmp normal
dotele:
mov ecx,[x]
sub ecx, 50 //ecx =x
mov [edx+0xF00],ecx
mov ecx,[y] //eax = y
sub ecx, 15 //eax = y
mov [edx+0xF04],ecx
mov [edx+380],13
normal:
pop ecx
pop edx
mov [edi],eax
mov ebx,[ebp+14]
jmp returnhere
returnhere:
}
} |
Look at the script, the "x" and "y" isn't identified and I'm pretty much stuck on allocating memory for them. So when I allocate memory for it, they are defined right?

Use VirtualAlloc/VirtualAllocEx to allocate memory of a given size.

Just define them as DWORDs outside of the function?
DWORD X;
DWORD Y;
At the top under your includes. They are given memory addresses then and can be used to store values. You can also access them from other functions if need be.
