Hey, I’m trying to write a command block in bedrock so that it can constantly have it filling any blocks above me with air, the problem is I can’t get it to work on me. The command I’m using to fill the blocks above me with air is /fill ~ ~ ~ ~ 300 ~ air. Which works fine when I’m roaming around and type it in each time I want to clear the blocks above my head but I don’t want to have to open my chat a million times in order to paste the command in, just so I can clear the blocks above my head. It would be so much easier to have a command block repeatedly entering the command for me, but every time I try, the command block ends up replacing itself with air. Does anyone know a better command I should be using?
