Firing a bullet makes my Sprite jump backwards

I have an issue I cant seem to stop from happening. In my game a ship is firing a bullet. For some reason when it fires the bullet the ship sprite jumps back.

This didn't always happen using the same logic for the mouse click so I am at a loss. Any help would be appreciated.

Hard to tell without a capx, what behaviors do you have on the ship and redball?

perhaps the ball is pushing the ship back with physics or something.

try spawning the ball elsewhere see if it helps, if it does, just add another image point away from the edge of the ship, far enough to fit the ball, and spawn it there.

maybe because it has solid behavior.

You were right! I was under the false assumption that an object needed to have the solid property to collide but I guess not. Thank you both for your ideas!

you're welcome. good luck on your game
