Hey there, so I'm really new to Assembly I read some Tut and watched videos about it, I got the basics but I want to understand why this script of mine keeps changing every time I open the game

Originalcode:

mov [rax+18],ecx
mov rax,[rdi+10]
jmp return

My New code was adding

mov [rax+18],(int)999

In the end the code looks like that

//mov [rax+18],ecx
mov [rax+18],(int)999
mov rax,[rdi+10]
jmp return

And now what exactly is your problem with this script???

Because the instructions are not using static address and its being created on runtime ?. Rolling Eyes

Template -> AOB Injection

My problem is that the script is not working as it should while I restart the game, can someone explain me what I need to do like step by step please ?

Or direct me to a specific guide for that ?

Yes AOB Injection used and unity game too.

Could you please post the whole script? Because AOB-Injection should do for you but it's hard to figure out a problem without seeing the content.

2 possible reasons:

1. code create on runtimes, so , you have to do something like opening the inventory/etc to dump the code before activation of script.

2. wrong injection location which maybe, the aobscan not unique enough. You can check this by scanning that aob signature eg: Value type set to Array of byte -> copy & paste the aob signature into the value to scan bar -> gray out all the protection eg:Writable/Executable/CopyOnWrite -> Scan -> if there're more than a result, make sure the first result is the right injection point -> else, make the aob signature longer/more unique.

When creating your scripts, in order to ensure that CE generates a more reliable AOB signature, it is better to not have any other scripts activated during that time, otherwise, the signature that CE generates for you may not be unique.

Oh I'll remember that, but yea this one was the only Script I was working on at the time nothing else, I will also have some time working on health, the issue about the Health is that the Address is sub the HP from AI's too, I tried using the Dissect data to find Different Values/Groups whatever but unfortunately did not worked.
