In Roblox Obby Creator , the usual way to delete everything is to enter Edit Mode, open the selection tools, select all parts in the obby, and then hit Delete. A tutorial result also notes that if someone else deleted your entire obby and you have edit access, you may be able to restore it with the Revert button in Settings.

How to clear everything

  1. Go into Edit Mode.
  2. Use the multi-select or select-all option to highlight the parts in your obby.
  3. Press Delete to remove the selected parts.
  4. If you deleted the wrong thing, use Undo ; on PC, tutorials mention Ctrl+Z for undo and Ctrl+Y for redo.

If you mean the whole obby

  • If you want to remove the entire creation, the safest route is usually to select everything first and delete it in one go.
  • If the obby was damaged or wiped by someone with edit access, the wiki and tutorial sources mention a Revert option in Settings as a recovery method.

Important note

One wiki page warns not to give edit access casually, because another editor can delete the entire obby. That makes backup habits and careful permissions especially important.
