Can I destroy all the blocks on a superflat?

Question

I'm looking for a command compatible with my iOS MCPE Superflat, one which will destroy all dirt, bedrock, and grass blocks.

I've tried /setblock (~x ~y ~z) air 0 replace <block>, but it doesn't work.

If anybody knows a command that is able to do what I'm looking for, or knows a map for skyblock, please let me know.

Thank you :)

Answer 1

There is a superflat void preset for Java edition, but I assume that it doesn't exist for PE.

You cannot place or remove blocks in unloaded chunks, either, so it is impossible to destroy the entire world.

You can use the command /fill ~45 ~-1 ~45 ~-45 ~-4 ~-45 air (Don't go any higher than ~45 because the max amount of filled blocks is 32767). Or set 3 repeating command blocks, with these commands in them: /execute @a ~ ~ ~ fill ~45 ~-1 ~45 ~-45 ~-4 ~-45 air 0 replace grass, /execute @a ~ ~ ~ fill ~45 ~-1 ~45 ~-45 ~-4 ~-45 air 0 replace dirt, and /execute @a ~ ~ ~ fill ~45 ~-1 ~45 ~-45 ~-4 ~-45 air 0 replace bedrock. this will cover more area and all you have to do is walk (or fly) around.

Answer 3

you can use /fill ~x ~Y ~z ~x ~Y ~z air
