2 Problems, (Playing a sound and Lightning (spotlight)) [BOTH SOLVED!!]

[Dark88]

Forget what I said it's working. but only if I make it so the callback won't be removed. (It's an option inside the LEVEL EDITOR)

But I actually want it to only be able to happen once.
Is there a special function that would do this? (Maybe to delete the sound of delete the callback?

Oh 1 more thing. I read somewhere that there is a function page which shows all the function but I can't find it.

Do you maybe know where I could find it?

Thanks in advance

I really appreciate it man!

The PlayerInteractCallbackAutoRemove check box just under where you put the PlayerInteractCallback should AutoRemove it if checked.
