You can simply use the function break this will break the function of your loop also you can use a return because return breaks loops/values

If you're looking to PAUSE a function, I don't believe there an official function for that BUT you can do it a hacky way.

repeat wait() until value == true

This would yield the script until the value (it may be a local value or an instance value) turns true.

If you're looking to break a function completely though, you can simply use the break or return functions.
