How to make a on clicked regen button?

I only can remember publicly clicked, but here's what you need to do.

First, insert a ClickDetector into the Part you want to be used.

Next, insert a Script into the part

Now, insert this into the script:

(NOTE: This is just the functioning; there are different methods of Regenerating a part or game, so you insert your own method.)

function OnClicked()
-- This is where you insert your method.
end

script.Parent.ClickDetector.Clicked:Connect(OnClicked)

I hoped this worked, and wasn't confusing at all for you.
