can someone please tell me how to use it I have no idea how to use it and I don't really understand the wiki.
It's basically a function onTouched() that can also be used as a button at times. Basically, it carries out some sort of action.
Personally, I'd stick with using "function onTouched()" as that service seems a bit difficult to use efficiently. If you don't know how to use function onTouched() either, shoot me a PM and I'll assist.
