 |
|
Hello, I'm new to Cheat Engine and there's a small trainer I'd like to make for Ethan Meteor Hunter.
After following the tutorial I was able to find the value to freeze in the game via a code replaced with 'nop' because the address changes each time.
This works very well but I'd like to add a keyboard shortcut to perform the code replacement. I can't see any way to do that in the code list, and there's nothing in the cheat table to allow for a hotkey to be created.
How could I do ?

If you're just NOPing an instruction, then you can make a script that'll do it for you. Then, assign the script to your cheat table, right click on it, and select "Set Hotkeys". CE will explain what to do from there.
Making a script to just NOP an instruction is relatively easy. Go to Memory View -> Tools -> Auto Assemble, then Template -> Cheat Table framework code. If the address of the instruction is inside a module (anything of the form asdf.exe+X, where X is some offset), then you can just type it out like that using this:
| Code: | // instruction is:
// asdf.exe+777 - 89 5C 24 18 - mov [esp+18],ebx
[ENABLE]
asdf.exe+777:
nop
nop
nop
nop
// nop 4 times because the instruction is 4 bytes long
// alt: db 90 90 90 90
[DISABLE]
asdf.exe+777:
mov [esp+18],ebx
// replace with original bytes on disable
// alt: db 89 5C 24 18 |
If that instruction isn't inside a module, then it's being dynamically allocated, meaning the code won't be in the same position if you restart the process. In that case, you'll need to do an AoB scan to get the address:
| Code: | // instruction is:
// 01931142 - 89 5C 24 18 - mov [esp+18],ebx <--the one we want to NOP
// 0193113F - 8B 7E 1C - mov edi,[esi+1C]
// 01931149 - 89 7C 24 20 - mov [esp+20],edi
[ENABLE]
// scans for this AoB, stores address of first byte into addyOfInstruction
aobscan(addyOfInstruction,89 5C 24 18 8B 7E 1C 89 7C 24 20) // must be unique
registersymbol(addyOfInstruction)
addyOfInstruction:
nop
nop
nop
nop
[DISABLE]
addyOfInstruction:
db 89 5C 24 18
unregistersymbol(addyOfInstruction) |
Note that the signature for the AoB scan must be unique. To check that, set the "writable" and "executable" checkboxes to grey in the main CE window, and scan for that AoB. If only one result comes up, you're good. If more than one comes up, get more bytes in your AoB signature.
