32    @file Asteroids2D.cc
33    @brief Implementation of the Asteroids2D class.
34
35    TODO:
36        - Implement a counting system for the score
37        - HUD can be improved (display health, points, level etc.
38        - Problem: The asteroids spawn randomly on the playing field.
39            During spawn or level up, there is the possibility that they pawn at the position of the ship.
40            ->spawn somewhere with a safty distance/radius
41        - look over collisionshapes of the stones ->  sometimes collison with stone is not triggered for bigger stones
42        - modify parameters in data/levels/templates/spaceshipAsteroids2D.oxt for a better playing experience -> mass, damping, rotation etc.
43
44    IDEAS:
45        - make Asteroids more beautiful! (setting, ship, explosion particles, stones)
46        - particle effect after you got hit -> during bImmune is true
47        - implement shield -> object that can be triggered
48        - Projectiles should also move over the boarders and appear on the other side
49            -> they can also hurt the player
