At the moment I have the controls working: rotation, thrust and fire. I have implemented the ship and the "bullets" simulation and now I am going to develop the asteroids and the interactions between bodies.
One interesting thing is that the shots fly at a constant speed, so if the ship is advancing at top speed, a shock wave is produced.
when I have all the physics working maybe I'll change the colors and some behaviours, shall see.
I'll keep you updated, regards.
