Undo and redo
⌘Z takes back anything you did in the editor, even deleting a level. ⇧⌘Z puts it back again.
How to
- Press ⌘Z, or ↶ Undo in the toolbar, or Edit → Undo.
- Press it again to go back one more step. Keep going as far as you need.
- Went too far? Press ⇧⌘Z, or ↷ Redo, to put a step back.
What it can undo
| In the Level tab | Moving, adding, deleting and duplicating objects. Make a grid. Changing any setting on the right. Renaming. |
|---|---|
| In the Game tab | Adding, moving, duplicating and deleting levels. After a delete NutHouse says “Level deleted” and reminds you that ⌘Z brings it back. |
| In the Events tab | Adding and deleting rules, conditions and actions. Changing their settings. Moving rows into groups. |
| In the Sprite editor | Every pencil stroke, fill, flip and paste. |
| In the tutorial | Do it for me does a step while you watch. Then ⌘Z puts the step back for you to try yourself. |
What it cannot undo
Saving a file, sharing a web page, and anything that happened while the game was playing. Playing runs on a copy, so there is nothing to undo there anyway: press Esc and the level is exactly as you left it.
Changing the mode is not a change to your game either, so Undo does not go back through Simple, Advanced and Expert. Click the mode you want.
Undo is per game
The undo list belongs to the game you have open. When you press New, Open or pick a sample, the list starts again from empty. That is one more reason to save before you open something else.
