Hooked use

[Peter12]

Hello,
I have problem with hooked Tibia 7.72 use.
I hooked it like this:

typedef void _UseContainerItem(int arg1, int arg2, int arg3, int arg4, int arg5, int arg6);
static _UseContainerItem *UseContainerItem = (_UseContainerItem*)0x438FA6;
When Tibia calls this function it looks like this:

But when i call this function:


UseContainerItem(0, 2, 0xE0F, 2, 0x40, 0xFFFF);
it looks like this:

Could anyone tell me what is wrong?

the 0x40 argument is carried via EDI, not the stack.

So how should i modify this?

Not sure if this will work, could you show us some more of what is done in asm before the function is called?



DWORD arg5 = 0xFFFF;
DWORD arg4 = 2;
DWORD arg3 = 0xE0F;
DWORD arg2 = 2;
DWORD arg1 = 0;
DWORD EDIarg = 0x40;

DWORD function = 0x438FA6;

__asm{
PUSH arg1
PUSH arg2
PUSH arg3
PUSH arg4
PUSH arg5
MOV EDI, EDIarg
CALL function
}

@edit
ok, i figured it out.
Just wrong address. I should enter the function first.
