So, I'm working on a server with bases, I won't say much more because the idea is unique and has never been done before.

I want to be able to have by default, an open gate comprised of 1-2 objects that will close when an enemy player comes close to them.

So basically, you have the gate open, and if a player comes near it, they will close until he goes away from them.

I don't need you to make it for me, I simply want an explanation of how this works, because I am a new scripter trying to learn.
