What is Box2D
Box2D is a powerful 2D rigid body simulation library designed to bring realistic physics to your game world. It allows game developers to simulate the movement and interaction of objects in a way that mimics real-world physics.
Box2D Features
-
Rigid Body Simulation: Simulate the movement of objects with realistic physics, including mass, force, and torque.
-
Collision Detection: Efficient algorithms to detect and handle collisions between objects, preventing penetration and simulating friction and restitution.
-
Joint Constraints: Support for various joint types, including revolute, prismatic, and distance joints, with options for limits, motors, and springs.
-
Continuous Collision: Advanced algorithms to handle tunneling and ensure accurate collision detection over time.
-
Event Handling: React to simulation changes with events like body movement, contact begin and end, and contact hit events.
-
Modular Design: Includes math and collision features that can be used independently of the rigid body simulation.
