I want to make a deathmatch zone, but I don't want players to have weapons anywhere outside that deathmatch zone. So if a player, for example, teleports to /chainsawmatch, he will be teleported to the chainsaw deathmatch, and automatically gets a chainsaw. But when he drives/flys/teleports to somewhere else, that chainsaw will be gone.
How can I create this?
