I'm not savvy with code, i have no idea what to do here. I've been playing with Ooblets and suddenly the code i was using doesn't work. Says Error while scanning for AOB. Below is what is printed in the box. I'm so sorry if this isn't the right place to ask this. I'm not new to Cheat Engine as far as using it, but vie never known how to fix this error and I've had it on other games as well. If anyone could help ya girl out i would very thankful <3

Hello,
just from looking at your AOB (array of bytes) is wrong:

This is what your scanning for:
E8 F3 0F 5A C0 F2 0F 5A E8 F3 0F 11 AF 38 01 00 00

This is the correct AOB:
E8 F3 0F 11 AF 38 01 00 00 F3 0F 10 87 38 01 00 00

You could add some wildcard's like this:
E8 F3 0F ?? ?? ?? ?? ?? ?? F3 0F ?? ?? 38 01 00 00

If you follow the way I've shown you by not allocating memory and using the INJECT point your AOB's will stay the same and you won't need the wildcard's ?? to fix the broken AOB.

Cheat Engine thread on how to use alloc:
https://wiki.cheatengine.org/index.php?title=Auto_Assembler:alloc

alloc(energy1,8,INJECT) this is 8 bytes right if you look at the broken AOB below:
E8 F3 0F 5A C0 F2 0F 5A E8 F3 0F 11 AF 38 01 00 00
Correct AOB below:
E8 F3 0F 11 AF 38 01 00 00 F3 0F 10 87 38 01 00 00
Count the bytes that are different it's exactly 8.
Correct way:
alloc(energy1, 0x4)
A float is exactly 4 bytes not 8 bytes.

I gathered the correct AOB from your script by looking at the bottom!

Your alloc energy1 inject is the culprit for your skewed/changing AOB's, so in future try out the methods I've posted for you.

You can just use label to be a memory address instead of allocating a small chunk of memory, if you want to edit this amount just registersymbol the labelname and add an address to your table as the exact symbolname!

@apocalypticx thank you so much, you are a wonderful human! I really appreciate you taking time to help me <3

No worries, if you want any examples of how to have an editable address in your cheat table that can be used to manually input any value let me know.

SO this isnt *mine* its from a 2 year old forum post from another site. I honestly have no idea how to do any of this. The only other thing i would possibly want in this would be the ability to add items to my inventory. There was an old ooblets table that could do it on the same post that doesn't work any more sadly, that used to be able to do it.
