Aether.Physics2D is a 2D collision detection system.


Web Demos:


  • Continuous collision detection (with time of impact solver)
  • Contact callbacks: begin, end, pre-solve, post-solve
  • Convex and concave polyons and circles.
  • Multiple shapes per body
  • Dynamic tree and quad tree broadphase
  • Fast broadphase AABB queries and raycasts
  • Collision groups and categories
  • Sleep management
  • Friction and restitution
  • Stable stacking with a linear-time solver
  • Revolute, prismatic, distance, pulley, gear, mouse joint, and other joint types
  • Joint limits and joint motors
  • Controllers (gravity, force generators)
  • Tools to decompose concave polygons, find convex hulls and boolean operations
  • Factories to simplify the creation of bodies

private Body _playerBody;
private Body _groundBody;
private float _playerBodyRadius = 1.5f / 2f; // player diameter is 1.5 meters
private Vector2 _groundBodySize = new Vector2(8f, 1f); // ground is 8x1 meters

//Create a world
_world = new World();

// Create the player
Vector2 playerPosition = new Vector2(0, _playerBodyRadius);
_playerBody = _world.CreateBody(playerPosition, 0, BodyType.Dynamic);
Fixture pfixture = _playerBody.CreateCircle(_playerBodyRadius, 1f);
// Give it some bounce and friction
pfixture.Restitution = 0.3f;
pfixture.Friction = 0.5f;

// Create the ground
Vector2 groundPosition = new Vector2(0, -(_groundBodySize.Y / 2f));
_groundBody = _world.CreateBody(groundPosition, 0, BodyType.Static);
Fixture gfixture = _groundBody.CreateRectangle(_groundBodySize.X, _groundBodySize.Y, 1f, Vector2.Zero);
