I am porting an Assembly script to Lua and I couldn't get it to work properly.

Could you please show me how to do it properly?

Until @ParkourPenguin arrives, let me give you an example.

There seems to be no errors for the code scheme.

But I can't be sure about the AA script.

Thank you that didn't do anything per se however you showed me that I could just use my assembly script the way it is and just pass it on to autoassemble(). Now it works better and everything in the Enable section works fine. But not the Disable section. in the Disable it only brings back the original bytes but doesn't deallocate.

tip: You don't need to use {$lua} other than once it will recognise [Enable] and [Disable] sections without {$asm}

[AylinCE]

I don't know much about AA script. You will do something there.

But if you wanted to use this in a Lua script, it would look like this with the help of a "CheckBox".

(I won't touch the disable allocation or code AA script code.)

Well, I could only appreciate your help. I also don't know much about Lua if any. It's all thanks to you and ParkourPenguin if I know some Lua at this point.

And Yes, this code you just provided can be helpful )

"It doesn't work" isn't a good description of the problem.

You're not doing any error handling. That should be the first thing you do when something isn't working. You should be doing it all the time anyway even when you expect everything to work properly.
Check if AOBScanModuleUnique returns nil or 0. Check if allocateMemory returns nil or 0. Check if autoAssemble worked properly.

The second parameter to `allocateMemory` needs to be an integer, not some arbitrary address string. Use `getAddress(process)`

`newmem_infHealth` and `oldBytes_infHealth` are undefined in the [DISABLE] section. Enabling and disabling the script are two separate script invocations: local variables aren't carried over.

I could explain more if you need me to.

The instance that was provided by AylinCE didn't do anything when I activated it. It didn't allocate nor did it place a jump and that's evidential if we look closer at the code. The code was supposed to run as Lua however it got passed on to autoAssemble() which expects a string of assembly.

What I also mentioned is that what he showed me by passing everything on to autoAssemble() was a great idea and it worked' It placed a jump at the expected location wrote the expected piece of code and jumped back to the next set of instructions as a normal AA script would behave. However, the only difference between this and a normal AA script is that this doesn't deallocate the chunk allocated so the cave remains untouched although the script is disabled and the original bytes got written back.

It unregisters the symbols as expected but does not deallocate.
side note it also doesn't recognise asterisks as all definitions

You're not keeping track of the disableinfo at all, and you're still not checking for errors...

I've got everything to work properly except for one thing. The script checkbox will turn on even if the script is not activated due to unfound AOB.

I want to know how to disable a script when it's unable to find the AOB.

I've seen somewhere that this line will disable the script. However, this doesn't let my script run because of an error it gives. When using it without wrapping it in function the script runs but it doesn't disable the script. So in this case using return is still better.

{$lua} blocks are run in the process of enabling a script. When they're executed, the AA script is neither enabled nor disabled. Trying to access, let alone change, a script's Enabled property in such a state doesn't make sense.
