Reason:
For instance if I defined symbols (JumpHack) & (No_Damage). If I fail to unregister (No_Damage) & reActivate the JumpHack Script. CE will use the registered memory location of (JumpHack). This doesnt Always happen but it happens from time to time. Especially when I crash the game.

Just wondering if there is a way to Unregister all symbols with a simple LUA action.

Not entirely sure that I follow. However...

In memory viewer, select view from the drop-down menu. Click on Userdefined symbols. From here, you can delete them all, or, a single entry at a time.

Alternatively:

Ctrl+M, Ctrl+U, right-click delete/delete all

Writing a simple LUA script to do that for you should be easy, but someone else will have to chime in for that. Perhaps, having an option under settings to automatically remove any remaining, user-defined symbols upon attachment of target process would be a good idea.

Writing an LUA script to perform this task should be easy for the LUA experts on this forum. All you would have to do is drop it in to your autorun folder, and it could run in the background, every time you started CE.

I don't think there's any easy way of unregistering all userdefined symbols.

If you have two scripts, then try to keep the symbols separate from each other. If one script is dependent on another one being active, then add it as a child of the script that needs to be active, right click on the main one, and select "Group config -> Hide children when deactivated".

If you're talking about the prompt you get when you reattach CE to another process while a script is still active asking you if you want to disable the scripts without executing the [DISABLE] section, then of course it's not going to unregister the symbol since you're not telling it to. I'm not entirely sure in what order CE executes an AA script, but maybe Lua code is run before it looks up the symbols. If that's the case, unregister it by using unregisterSymbol(symbolname) in a luacall or {$lua} section in [ENABLE]. If that fails, you should be able to use the function registerSymbolLookupCallback(function(string):integer, location): ID to make it safe.

Posting all applicable scripts would be helpful.

I've made it:
put the lua file in the autorun folder in cheat engine dir.
it adds a button just below speedhack that unregisters all the registered symbols.
KNOWN ISSUES:
when you click execute on the AA window, then click cancel, it still counts the symbols as registered, not a big issue, I could fix it if needed.
[important] does not remove the registered symbols from the list when you unregister them in script, I'll fix it soon.
FEATURE
supports block comments, for example:

Yeah This Awesome. Thank You.

And my apologizes for the confusion about the intial post it was only a Reason for the request. I always find some strange bug when i am hacking into a game.

Thanks Redouane. Do you care if I edit and reuse your contribution?

Good work, Redouane! I'm curious about why you chose not to have the script utilize CE's delete user-defined symbols feature?

Thanks.

++METHOS - I'm not sure if there are any besides unregisterSymbol(name). I tried searching through main.lua but couldn't find anything that would give any reference to all registered symbols.

Redouane - Your script also doesn't take into account symbols registered manually and symbols registered via a Lua script w/ either registerSymbol(...) or SymbolList.register(). This also won't work if there's anything before the AA call to registersymbol(...) (i.e. spaces), nor will it work if anyone capitalizes any letter in registersymbol (e.g. registerSymbol(...) is perfectly valid).

Hmm. I wish I knew LUA, but I don't. So something like this can't be done with LUA(?):

The documentation in main.lua explains it well enough. When you call register(), it basically just takes every symbol in the list and registers it. I've never used it nor have I ever seen anyone else use it, so it's probably a pretty rare thing.
