If you want another level, you can base it off an existing one like this:

  • Switch to the scene for the level you want to duplicate
    • If it’s not already open, find the corresponding file in the FileSystem tab, and double-click on it
  • From the Scene menu, choose Save Scene As:

Save Scene As

Now we have a separate file for our scene, and we can make changes without affecting the previous scene.

  • Press F6 to test the currently active scene, or use the Run Current Scene button:

Run Current Scene

  • Or, in the FileSystem tab, Right-click on the scene file and choose Set as Main Scene:

Set as Main Scene

This makes it the scene that is loaded when you play the game using F5 or when you export the game.
