In this guide, I will show you how to make something happen (In my case, to run a repeater) when you are in a area.
First, you place down a zone, then place down a counter and wire repeater. Set the wire repeater’s delay to 0.0. Then, make wires like this: Player enters zone -----> increment counter. Then, make these wires: Player leaves zone -----> Repeat the wire pulse and make these wires: When the wire repeater receives a pulse -----> Decrement counter. This is what it should look like now:
Then, place a property, call it “In zone” then edit the counter so that the when the counter changes, update a property. And change the property type to a number. Then, place down a checker and set it to check the value of the property. Make check one see if the property is one.
