how do i stop players from breaking blocks in my world?
Hi @bossosking:Hm, I'm not entirely sure about de-opping friends in your world. I'll let you know! However, you can also type in /close to close your server so that no one can join for now.
Load your world and go onto Host Privileges and put Trust Players on it will stop them from breaking, placing, or harming in your world.
I just found out about this topic. You can do /gamemode 2 which will change that player's game mode to Adventure mode. You could also try de-opping them so they can't change back.
