sternenseemann / grav2ty

2d space flight game with realistic physics

grav2ty 🚀

the most realistic asteroids-like game in existence.

controls

• up/down: increase/decrease thruster power (ship acceleration)
• left/right: rotate ship (counter)-clockwise
• c: toggle centered view
• +/-: zoom in/out
• space: fire a projectile

roadmap

• simulation of gravity
• controllable spaceship
• collision detection
• make measurements more realistic
• allow for zooming the viewport
• Free viewport (mouse moved)
• time scaling / fast forward
• rework HUD, log additional info to console
  • Add speed to HUD
• projectiles
  • Limit firerate
  • make projectiles self-destruct
• performance improvements
  • don't calculate gravity to every little object
  • don't do collision detection at a safe distance
• multi player support
• Prevent library user from creating a broken state (by hiding lenses etc. if possible)
• cosmetics (improved models, stars, …)
• switch rendering engine
• orbit visualization / prediction
