At the moment I'm trying to make a AOB scan, with the help of Rydian guide (?t=572465).
The most I got to work I just make a few mistakes why it doesn't works at the very end.

I was able to make the following steps:
1. Search the right address.
2. Find the offset.
3. Subtract the offset of the address (1).
4. Here comes the tricky part if I'm doing it right.
Adding the address manually, then I'm not sure if I need to manually add the first address or the subtract address (I assume the first address).
After I'm not sure if I need to fill in the field the first address or the subtract address.
5. I was be able to get a few samples and compared make them compare to each other.
6. I was able to add the script with my signature.

Whenever I did activate the script nothing much happened.
Also I wasn't able to remember the address when switching over to different level or restarting the game.

I'm testing this on the game Offspring Fling!
Any help would be appreciated, thanks in advance.

I think you messed up at step 4. You have to fill in the suctracted address (which is the base address)
And you don't really have to "Add address manually", you can just open the Memory View menu, in the bottom half, right click and "goto address", paste in the subtracted address, then work out the AOB of that base address and then continue !
Also if your AOB scan doesn't work then maybe one byte of your AOB changes when restarting the game. If your address change when switching over to different level but the AOB doesn't then just simply deactivate then reactivate the script.

Did you forget the offsets you mentioned?

player+88:

player2+90:

Then the label becomes the correct address reference.

You forgot the offsets. Daijobu has pointed it out right there.
Your script should look like this

Seems like _player one works even without the offset (I guess since I already subtracted that with the calculator).
But it only works on the first level, but won't work on level 2 and 3 for example.
The won't even activate at level 2 and 3 only on level 1.

_player2 won't work at all, with or without the offset.

EDIT: I searched in the Memory View the abstracted address, I did this correct ?

Then your one or some bytes of AOB changes when switching levels, try to work out another better AOB.
Sorry I don't have that game to help you.

When I keep scanning those 2 different addresses start to look identical to eachother.
I probably did something very wrong somewhere.

I searched in the Memory View the abstracted address, I did this correct ? Or should I search for the scanned address ?

EDIT:
I just did a clean scan
Here some results I got:

00 00 00 00 01 00 00 00 01 00 00 00 10 00 00 00

Which results to a failure again.
I am thinking that I might need more lines, gonna test that right now, I will keep you up to date about result, any advice in meentime is welcome. Smile

You cannot scan for half of a byte. 0?, ?0, 9?, and anything similar is treated simply as ??.

No success at what? Does the script not activate? Or you simply don't know the correct offset?
You know that +88 is hex, right? You're moving over 136 bytes.
If you only want to move over 88 bytes, it should be +58.

Also, do an Array of Bytes scan using the Table.
Is that string of bytes returning more than 1 address?

Select Array of byte from the Value Type dropdown.
Then simply paste your full string (with spaces) into the search box.
?? 00 00 20 ?? ?? ?? ?? ?? ?? ?? ?? 00 00 00 00 01 00 00 00 02 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00 01 00 00 00 01 00 00 00 10 00 00 00 1C 00 00 00 08 00 00 00 0E 00 00 00 00 00 00 00 00 00 00 00 ?? ?? ?? ?? ?? ?? ?? ?? A8 AD ?? 04 28 C3 ?? 03 ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? 00 00 00 00 00 00 00 00 00 00 00 00 ?? ?? ?? ?? 00 00 00 00 ?? ?? ?? ?? A0 ?? ?? ??

If you get no results, then you messed up those bytes and that's why you can't enable your script.
