Hi,
In the following code Adress is a newmem allocated in an other script PlayerBase is a pointer to a struct

Code:

[ENABLE]

define(Setinvincible,Character_CustomModule:PersistentUpdate) // should be unique
define(ResetBytes,Adress+A1)
registersymbol(Setinvincible)
registersymbol(ResetBytes)


ResetBytes:
  db 48 83 EC 08 48 83 C4 08


Adress+50:
  push rax
  mov rax, qword ptr[PlayerBase]
  add rax, 2A1
  mov byte ptr [rax], 01
  mov rax, qword ptr[ResetBytes]
  mov qword [Setinvincible], rax
  pop rax
  jmp Setinvincible

Setinvincible:
  jmp Adress+50
  nop
  nop
  nop

[DISABLE]

Adress+50:
  push rax
  mov rax, qword ptr[PlayerBase]
  add rax, 2A1
  mov byte ptr [rax], 00
  mov rax, qword ptr[ResetBytes]
  mov qword [Setinvincible], rax
  pop rax
  jmp Setinvincible

Setinvincible:
  jmp Adress+50
  nop
  nop
  nop

unregistersymbol(Setinvincible)
unregistersymbol(ResetBytes)


Cheat engine doesn't let me compile this script due to this line : mov rax, qword ptr[ResetBytes]
in the Disable section wich is the same as the one in Enable section, so i found a way to bypass that by just
modifying the Disable section like this :
Code:


[DISABLE]

Adress+5E:
  mov byte ptr [rax], 00

Setinvincible:
  jmp Adress+50
  nop
  nop
  nop

unregistersymbol(Setinvincible)
unregistersymbol(ResetBytes)

this solution works fine but it doesn't explain why it wouldn't let me compile even when it's literaly the same line at the same adress in the enable section

I'm not sure what's going on. Maybe the symbol `ResetBytes` is getting re-registered elsewhere...?

Does it work if you put `define(ResetBytes,Adress+A1)` above [ENABLE]?

Yep that was the problem apparently. I guess it just "undefine" it automaticly when disabling, im gonna add all my define in the parent script so it won't be a problem. Thanks you for the answer !
