I am working on a game that require me to have a cannon controlled by arrows. I think I can get the movement to work but I need it so that way I can have the cannon shoot when I press a button. So I would have the canon moving (2 seperate images) and then the opening shoot a image. How would that work?

Looking for something like this ?
