Hi Guys,

Could anyone please explain why this code won't activate e.g. the checkbox won't tick

Code:

[ENABLE]

//-----------------------------------------------------------
// Ammo
//-----------------------------------------------------------
aobscanmodule(aobAmmo,FC_m64.dll,8B 43 0C 48 8B 5C 24 30)
registersymbol(aobAmmo)
alloc(varAmmoMemory,1024,FC_m64.dll)

label(lblAmmoCode)
label(lblAmmoSkip)
label(lblAmmoReturn)
globalalloc(varAmmo,4)

varAmmo:
  dd 0

//-----------------------------------------------------------
 
varAmmoMemory:
  cmp [varAmmo],1
  jne lblAmmoSkip


lblAmmoCode:
  // Activated Code
  mov eax,(int)99
  mov rbx,[rsp+30]
  jmp lblAmmoReturn

lblAmmoSkip:
  // Deactivated Code
  mov eax,[rbx+0C]
  mov rbx,[rsp+30]
  jmp lblAmmoReturn

aobAmmo:
  jmp varAmmoMemory
  nop
  nop
  nop

lblAmmoReturn:

//-----------------------------------------------------------

[DISABLE]

//-----------------------------------------------------------
// Ammo
//-----------------------------------------------------------
aobAmmo:
  db 8B 43 0C 48 8B 5C 24 30

unregistersymbol(aobAmmo)
dealloc(varAmmoMemory)


But this code does activate

Code:

[ENABLE]
aobscanmodule(aob_Ammo,FC_m64.dll,8B 43 0C 48 8B 5C 24 30)
registersymbol(aob_Ammo)
alloc(newmem_Ammo,1024,FC_m64.dll)
label(return_Ammo)

newmem_Ammo:
  mov eax,[rbx+0C]
  mov rbx,[rsp+30]
  jmp return_Ammo

aob_Ammo:
  jmp newmem_Ammo
  nop
  nop
  nop
return_Ammo:

[DISABLE]
aob_Ammo:
  db 8B 43 0C 48 8B 5C 24 30

unregistersymbol(aob_Ammo)
dealloc(newmem_Ammo)


I'm pretty sure I'm missing something here but I can't see it.

Didn't really see a reason why it wouldn't activate.
try pressing Ctrl+Alt+A put the enable code there and execute, this tends to give better error messages.

The cmp instruction is attempting to directly address a memory location that could be outside the range RIP-relative addressing allows.

Instead of using globalalloc, you could define it as a label inside the allocated memory and register the symbol.
Code:
...
label(varAmmo)
registersymbol(varAmmo)

varAmmoMemory+300:
varAmmo:
  dd 0
...
Don't forget to unregister the symbol in the disable section.

@TheyCallMeTim13 Thank you for your reply, is that for the API Hook Template?

@ParkourPenguin Thank you, that is exactly what was stopping it from activating. weird I've used that code on quite a few games without problem

It's for any Auto Assembler code.
