Why is my animation not working

My animations aren’t working and whenever I try to use them my sprite just disappears and I don’t know how to fix it because I thought it would be so simple. I have tried changing things but nothing I’ve tried is working (The shotgun is supposed to play a firing animation when space is pressed)

That can happen if you have an image for the sprite’s animation that has been deleted or renamed. Make sure all the images for shotgun animation “1” exist.

Maybe you need to pause the animation after you set it at the start of the scene. It might be playing to the end before the scene starts.
