I am trying to create a vertical shoot'em up. I have been successful in display the ship to the screen, being able to move the ship and fire a single bullet from the ship. My only concern is being able to fire more than one bullet at a time. I added extra code to add this function into my programme, but as yet it has done nothing except to fire a single bullet, which can only be seen when I add the wait function, which slows everything down. I also encounter a problem when the sprite of the bullet reaches the top of the screen as it comes up with an error BOB does not exist on line 108. Please tell me what I am doing wrong and how I can alter my code to fire more than one bullet at a time.
