I am making a script in assembly and would like the change the blink distance for the power "Blink" in Dishonoured 2, but the issue is that when it is chnaged in the script it didn't change back, and I want to use this script to auto switch it bacl. I tried to rectify this by writing the script below but it just crashes my game after activation, I'm really not 100% sure why and would love and answer

Code:
Code:
[ENABLE]

aobscanmodule(BlinkDist2,Dishonored2.exe,F3 44 0F 10 44 D1 24 F3 0F 10 A6) // should be unique
alloc(newmem,$1000,BlinkDist2)
alloc(StoreValue,256)

label(code)
label(BlinkDistance)
label(StoreBlink)
label(OldBlink)
label(return)
registersymbol(BlinkDistance)
registersymbol(StoreBlink)
registersymbol(OldBlink)

StoreBlink:
  dd #1

BlinkDistance:
  dd (float)15

StoreValue:
  OldBlink:
  dd (float)0
  push rbx
  mov rbx,[OldBlink]

newmem:
  cmp [StoreBlink],#1
  jne code
  mov [StoreBlink],#0
  push rax
  mov rax,[rcx+rdx*8+24]
  mov [OldBlink],rax
  pop rax
  jmp code

  code:
    push rax
    mov rax,[BlinkDistance]
    mov [rcx+rdx*8+24],rax
    pop rax
    movss xmm8,[rcx+rdx*8+24]
    jmp return

BlinkDist2:
  jmp newmem
  nop 2
return:
registersymbol(BlinkDist2)

[DISABLE]
mov [rcx+rdx*8+24],rbx
pop rbx

BlinkDist2:
  db F3 44 0F 10 44 D1 24

unregistersymbol(StoreBlink)
unregistersymbol(BlinkDist2)

Your DISABLE section is wrong.
Where are you writing that code?

@Csimbi I’m writing it back to the address that was originally used (in vanilla game) for blink distance ([rcx+rds*8+24]) as to restore the the value from OldBlink back into it, the OldBlink value being in rbx…

mov [rcx+rdx*8+24],rbx
pop rbx

BlinkDist2:
db F3 44 0F 10 44 D1 24

SHOULD BE

[DISABLE]
BlinkDist2:

Thank you very much but how would I move the OldBlink value back into the address on disable?
