How can you make it so only one player or certain group of players can walk through a brick. I do not wish to accomplish this with killing, teleporting, or setting the cancollide so that two players could go in at once. I've seen it done more and more and I'm dying to know. Don't give me code, just tell me how its done, like what I should look into to figure it out.
Turn on FilteringEnabled and make a LocalScript that sets the door's CanCollide to false if the player is that one player or in that group of players.
