How to Stop Mobs From Destroying Blocks

“Mob griefing” covers anything a mob does that changes the world itself, rather than just fighting players — a creeper crater in a wall, an enderman walking off with a block, a ravager flattening a fence. The mobgriefing gamerule turns all of it off in one switch.

Disabling It

bash

gamerule mobgriefing false

Run that from the panel’s Terminal tab — no / needed. In-game it’s /gamerule mobgriefing false, and needs operator permission. The log confirms:

text

[INFO] Game rule mobgriefing has been updated to false

With it off:

Creeper, ghast, and wither explosions no longer destroy blocks (they still damage players and entities)
Endermen stop picking up and placing blocks
Ravagers stop destroying blocks as they charge

Note

mobgriefing doesn’t touch TNT — that’s a separate, Bedrock-only gamerule called tntexplodes. If TNT is the actual problem, that’s the one to turn off.

Warning

mobgriefing is all-or-nothing — there’s no vanilla gamerule that disables explosion damage to blocks while leaving the rest of the list above untouched.
