 |
|
So I play Nobody saves the world and try to cheat mana gain
what the code do is doubling the mana gain
it work for a while, but it will crash the game after a while (indefinitely)
my question is, is the problem lies within my code?
| Code: |
[ENABLE]
aobscanmodule(MANA,NStW_x64.exe,F3 42 0F 11 84 9B D4 00 00 00 48 8B 1C 24) // should be unique
alloc(newmem,$1000,MANA)
label(code)
label(return)
label(angka)
label(nol)
newmem:
comiss xmm0,[nol]
je code
comiss xmm0,[rbx+r11*4+000000D4]
jbe code
subss xmm0,[rbx+r11*4+000000D4]
mulss xmm0,[angka]
addss xmm0,[rbx+r11*4+000000D4]
angka:
dd (float)2.0
nol:
dd (float)0
code:
movss [rbx+r11*4+000000D4],xmm0
mov rbx,[rsp]
jmp return
MANA:
jmp far newmem
return:
registersymbol(MANA)
[DISABLE]
MANA:
db F3 42 0F 11 84 9B D4 00 00 00 48 8B 1C 24
unregistersymbol(MANA)
dealloc(newmem)
{

Instead of doubling, have you tried setting a fixed value that is not unreasonable?
On rare occasions, increasing values beyond their in-game maximums can cause targets to crash.

You have data in the middle of your code. After `addss`, the thread executes junk instructions. I'm surprised it doesn't crash immediately.
Move `angka` and `nol` after `jmp return`

I didn't notice that. That is probably the problem.
