Hi there,

Since I loss almost my scripts from my PC by an stupid accident then I need some help for write these asm code below to a function and also I dpn't know about asm too much :

Code:
[ENABLE]

aobscan(MOVES,89 48 24 8B 48 24 83) // should be unique
alloc(newmem,$1000)

label(code)
label(return)

newmem:

code:
mov ecx,#99
mov [eax+24],ecx
mov ecx,[eax+24]
jmp return

MOVES:
jmp code
nop
return:
registersymbol(MOVES)

[DISABLE]

MOVES:
db 89 48 24 8B 48 24

unregistersymbol(MOVES)
dealloc(newmem)

SCORE

[ENABLE]

aobscan(SCORE,89 70 14 8D 8B 80 09 00 00) // should be unique
alloc(newmem,$1000)

label(code)
label(return)

newmem:

code:
mov esi,#100000000
mov [eax+14],esi
lea ecx,[ebx+00000980]
jmp return

SCORE:
jmp code
nop
nop
nop
nop
return:
registersymbol(SCORE)

[DISABLE]

SCORE:
db 89 70 14 8D 8B 80 09 00 00

unregistersymbol(SCORE)
dealloc(newmem)

COINS

[ENABLE]

aobscan(COINS,89 41 24 8D 8B 80 09 00 00) // should be unique
alloc(newmem,$1000)

label(code)
label(return)

newmem:

code:
mov eax,#9999999999
mov [ecx+24],eax
lea ecx,[ebx+00000980]
jmp return

COINS:
jmp code
nop
nop
nop
nop
return:
registersymbol(COINS)

[DISABLE]

COINS:
db 89 41 24 8D 8B 80 09 00 00

unregistersymbol(COINS)
dealloc(newmem)

DIAMONDS

[ENABLE]

aobscan(DIAMONDS,89 41 28 8D 8B 80 09 00 00) // should be unique
alloc(newmem,$1000)

label(code)
label(return)

newmem:

code:
mov eax,#9999999999
mov [ecx+28],eax
lea ecx,[ebx+00000980]
jmp return

DIAMONDS:
jmp code
nop
nop
nop
nop
return:
registersymbol(DIAMONDS)

[DISABLE]

DIAMONDS:
db 89 41 28 8D 8B 80 09 00 00

unregistersymbol(DIAMONDS)
dealloc(newmem)


1. How to write that codes with correct syntax to a function ?.
2. And then I able to call that function by a button click. (This is easy and already knew)

Thanks

im not sure about what you mean with "correct syntax" and "to a function"

i read the script twice, there is no syntax error.
an exception for multiple enable-disable sections, CE wont accept it unless you combine them all under one enable-disable section.

Thanks OldCheatEngineUser, so no syntax error there, what I mean is something like this below :

Code:
function hack1()
  [ENABLE]
  aobscan(MOVES,89 48 24 8B 48 24 83) // should be unique
  alloc(newmem,$1000)
  label(code)
  label(return)

  newmem:
  code:
  mov ecx,#99
  mov [eax+24],ecx
  mov ecx,[eax+24]
  jmp return

  MOVES:
  jmp code
  nop
  return:
  registersymbol(MOVES)

  [DISABLE]

  MOVES:
  db 89 48 24 8B 48 24
  unregistersymbol(MOVES)
  dealloc(newmem)
  --- and so on.......
end

f = createForm()
b1 = createButton(f)

b1.onClick = hack1
f.show()


Is the function with asm codes written right ? or need typing something like "$Asm" or "[AutoAssemble]"..etc ?
Of course, a opened process already done in separate script.

To do it in Lua you just need to put your script in a string, then pass the string to the autoAssemble function.

TheyCallMeTim13, like this ? :

Code:
 local scriptStr = [==[
   [ENABLE]
  aobscan(MOVES,89 48 24 8B 48 24 83) // should be unique
  alloc(newmem,$1000)
  label(code)
  label(return)

  newmem:
  code:
  mov ecx,#99
  mov [eax+24],ecx
  mov ecx,[eax+24]
  jmp return

  MOVES:
  jmp code
  nop
  return:
  registersymbol(MOVES)

  [DISABLE]

  MOVES:
  db 89 48 24 8B 48 24
  unregistersymbol(MOVES)
  dealloc(newmem)
]==]

function hack1()
 ---- Enable script
 local enabledOk, disableInfo = autoAssemble(scriptStr)
 if enabledOk then
   print('The auto assembler script was enabled successfully.')
 else
   print('There was an error enabling the auto assembler script.')
 end
 ---- Disable script
 local disabledOk = autoAssemble(scriptStr, disableInfo)
 if disabledOk then
   disableInfo = nil
   print('The auto assembler script was disabled successfully.')
 else
   print('There was an error disabling the auto assembler script.')
 end
end

f = createForm()
b1 = createButton(f)

b1.onClick = hack1
f.show()

EDIT:
Yeah that looks good to me, and you can also use a new functions added in Cheat Engine version 6.7 to check syntax, autoAssembleCheck

But note that with "autoAssembleCheck" if you pass "TargetSelf" even as nil it will ignore the enable argument.
