  3. Add arguments one at a timeUse completion and read the error after every added argument so the failing segment stays visible.
  4. Bound the target and areaReplace unfiltered @e with type, distance, tag, or score filters and recheck coordinate signs.
  5. Document the result and recoverySave the working command in a command block or function and keep a practical cleanup command nearby.

SAFETY & EFFICIENCY

Mistakes and dangers

  • Back up the world before commands that change blocks, entities, inventory, or data.
