npm install impact2dThis is a light wight 2d physics engine for web development. Gives reasonable physics simulation for 2d convex geometries.
Very simple to use and configure.
Copy library code main.js from ./dist folder
``js``
const {Engine, Shapes} = Impact2d
const {Circle, RegPoly} = Shapes;
// Create a world 2000 pixels * 2000 pixels
let world = new Engine({scale: 2000, delta: 0.02});
world.setGravity = 1;
// Circle
let body1 = new Circle({
id: 'body1',
x: 100,
y: 100,
r: 30,
m: 100
});
// Regular polygon with 6 faces
let body2 = new RegPoly({
id: 'body2',
x: 400,
y: 100,
r: 30,
sides: 6,
m: 50
});
world.addEntity(body1);
world.addEntity(body2);
// Run the simulation
const tick = () => {
world.tick();
requestAnimationFrame(tick)
}
requestAnimationFrame(tick)
- Maintained a Quadtree for storing spacial data for efficient search and thus good performance.
- Built-in renders for fast drawing on the canvas.
