The object in my game doesn't turn around.

Hi. I’m trying to make a small game. I used the behaviors:flip once collided with(false door),and it isn’t working. Here’s a link to my game. Can you help me? It would be great if you would.

Your false door object has no default sprite, so it doesn’t have anything to build a hitbox around. Try setting your default sprite to the ‘Door open’ animation, and then using the alpha behavior block.

Thanks for the help!
