2D Physics Engine

Simulate complex physical interactions with real-time collision detection and gravity control

Canvas: 1280x480

Click "Add Box" and watch physics rules shape your digital world in real-time.

Box2D Integration

Leverage the industry-standard 2D physics library with advanced collision and distance detection tools.

Real-Time Simulation

Visualize physics calculations instantly with adjustable time-step controls and debug rendering.

Constraint Editor

Create complex joint systems and dynamic boundaries with interactive physics constraints.

// Physics Engine Demo
class PhysicsWorld {
  constructor() {
    this.box = new Box2D.b2BodyDef();
    this.fixture = new Box2D.b2FixtureDef();
    this.fixture.density = 1.0;
    this.fixture.friction = 0.3;
  }

  createBox(x, y) {
    this.box.position.Set(x, y);
    const body = world.CreateBody(this.box);
    body.CreateFixture(this.fixture);
    return body;
  }

  applyGravity(gravity) {
    world.SetGravity(new Box2D.b2Vec2(0, gravity));
  }
}

const world = new PhysicsWorld();

Interactive Demo

// Create your physics scene const world = new PhysicsWorld(); world.applyGravity(9.8); const box = world.createBox(5, 10);
