I've want to make a skyblock where it is impossible to go in creative. I was thinking to do this with a commandblock. Cheats on is not a real problem (with open to LAN) but the cheat: /gamemode 1 do I want to avoid. I've maid a circuit with a clock so that every second the commandblock set the gamemode on survival. But I think this is not a very good idea because it makes everything quite slow. I have ever saw a map where this feature was. So the moment you've changed to creative, it goes back to survival. Anyone an idea?
