 Posted: Sun Sep 26, 2021 2:14 pm Post subject: Help with multi-level pointers script |
 |
|
Hello everyone!
I'm struggling with a AoB script and maybe you can help.
As you can see from the attached file, what I would like to do is to copy the value of the Item4, then replace it to 0 and paste the value in Item6.
But I can't find a way to do it...
I could copy the value without problem.
But I tried many ways to move the value, and it's never the same value that appears in Item6...
What I did so far is this:
| Code: |
aobscanmodule(MoveValue,GameAssembly.dll,48 8B FA 48 8B D9 75 12 8B 0D) // should be unique
alloc(newmem,$1000,MoveValue)
label(code)
label(code2)
label(return)
// Structure
label(_PUI)
registersymbol(_PUI)
// Value to copy
label(_COPY_Item4)
registersymbol(_COPY_Item4)
newmem:
code:
mov rdi,rdx
mov rbx,rcx
mov [_PUI],rbx
push rbx
mov rbx,rcx
cmp rbx,0
je code2
mov rbx,[rbx+60]
cmp rbx,0
je code2
mov rbx,[rbx+10]
cmp rbx,0
je code2
push rax
lea rax,[rbx+40]
cmp rax,0
je code2
mov [_COPY_Item4],rax
pop rax
// -------------------------------
// Not working from here
//push rax
//lea rax,[rbx+50]
//cmp rax,0
//je code2
//mov [rax],_COPY_Item4
//pop rax
// not working either
//lea rbx,[rbx+50]
//cmp rbx,0
//je code2
//mov [rbx],_COPY_Item4
// not working either
//mov rbx,[rbx+50]
//cmp rbx,0
//je code2
//mov [rbx],_COPY_Item4
// -----------------------------
pop rbx
jmp return
code2:
mov rdi,rdx
mov rbx,rcx
jmp return
_COPY_Item4:
dq 0
_PUI:
dq 0
MoveValue:
jmp newmem
nop
return:
registersymbol(MoveValue)
[DISABLE]
MoveValue:
db 48 8B FA 48 8B D9
unregistersymbol(MoveValue)
unregistersymbol(_PUI)
unregistersymbol(_COPY_Item4)
dealloc(newmem)

| This isn't Lua. It's auto assembler.

Indeed, I first tried in assembler but it's a mess kinda.
Wanted to see in lua if it could be done easily maybe
I tried using {$lua} writeBytes, using the good offsets (takes less place than in asm) and so on but it was a dead end too.

This will find the entry in the table with Lua, set its value and then remove the value from the other entry.
| Code: |
[ENABLE]
{$LUA}
local al = getAddressList()
local item4 = al.getMemoryRecordByDescription('Item4 (offset+40)')
local item6 = al.getMemoryRecordByDescription('Item6 (offset+50)')
if item4 ~= nil and item6 ~= nil then
item6.value = item4.value
item4.value = 0
end
{$ASM}
[DISABLE]

Wow, thanks!
Extremely short and it works perfectly, couldn't expect better!

I hope it's understandable what the code is actually doing too. If you're curious about what Lua functions are available for Cheat Engine, you should check out celua.txt

Very clear, didn't think of using my local structure that way.
Was still trying to do everything, memory side lol
But yes as long as description is unique, it's a good way to extract things from the address list!
Thanks again for this method
