Orange: This section gathers all the values needed to calculate things.
Texturematrix = [pos x, pos y, time, speed, normalized x distance, normalized y distance, velocity x, velocity y, distance]

Blue: This section finds the angle between the velocity*textscale and the position of the Missile relative to scene.my.pos using atan2. Textscale changes how much velocity affects the angle.


Red: This section controls the angle of the rocket with the angle found in the blue section.

Green: This section spawn a circle every 3 frames (reduces memory leak).
Purple: This caps the speed at 100 m/s, it can be changed.
