I'm creating a Death Race map and I want to make sure only "OP's" can stay in Game Mode 1 and all the rest of the players stay in Game Mode 2 (in Minecraft 1.12)
I tried to leave a Command Block causing specific people to stay in Game Mode 1, but it is a map with a lot of players and I want to make it possible in the future to easily change who is in Game Mode 1 and Game Mode 2.
