You race with a Gokart, and your other friend stay on the Gokart with one Minigun. My friend have make so the Minigun don't do damage, so it just push you Thats the race. But we make the map in Team Action gamemode, thats make me need 2 scripts so it will work full out. 1 I need a script that creates Chekpoints that go to an other Checkpoint.
