Problem with Enemy 1 for the 8-bit space shooter

So I changed the sprite for the ship that flies back and fourth across the screen, and now it won’t move. I tried all I could think of, but still nothing. How can I get it to move again? I’m new to game development, so go easy on me if this is a stupid question.

Did you change the name of the animations? I think the exact same names are needed by the behavior that moves the enemy back and forth.
If you’re not sure, you can start over from the example.

My advise is that you create another project from the example then copy paste the object and just change the Sprites, previously delete the object but not the references.

I think that may be it. Thanks for telling me!
