helow my friend! Hmm, if you are trying to make a game similar do abuse (where the actor can look to any direction and fire to the direction that he's looking), try to understand the demo of this game on the site. I nice trick that u can do is put two actors, and link them by the "pattern" function. one actor will be the "body" of the hero, wich will move to right/left/jump. The other actor will be his head, wich can look to anyu direction. To make the head looking, try to understand the asteroids demo on the site to see how u can rotate your actor and change the fire direction (you will use some angle functions. If you don't understand how to use that on the demo, ask me again). With these two actors linked and programmed, you will be able to walk left/right/jump and look to all directions and fire to that direction.
See you latter my friend!
