SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Matter.js provides a robust 2D physics engine to simulate rigid-body dynamics, collisions, and constraints in web apps, removing the guesswork from interactive physics.

Core Features & Use Cases

Engine-based physics: simulation of bodies, collisions, and constraints in 2D.
Interactive demos and games: draggable objects, springs, and gravity-based scenes.
Use Case: build browser-based physics demos, educational visualizations, or UI motion experiments.

Quick Start

Initialize Matter.js in your project and create a simple world with a few bodies.

FAQPage Schema

How do I simulate 2D rigid-body physics in a web application?▼

To simulate 2D rigid-body physics in a web application, you can use Matter.js to set up an Engine, Render, and Runner, then add bodies and constraints to a World composite for interactive dynamics.

What is the best way to add draggable objects and collisions to a canvas demo?▼

Adding draggable objects and collisions to a canvas demo involves using a 2D physics engine with Mouse and Events modules, allowing users to interactively drag rigid bodies within a simulated world.

Can I use a 2D physics engine for browser-based games and UI motion?▼

Yes, a 2D physics engine supports browser-based games and UI motion by simulating gravity, springs, and constraints, enabling interactive visualizations and realistic object movements on the web.

How do I install and initialize Matter.js using npm or CDN?▼

Installing and initializing Matter.js via npm or CDN provides the Engine, World, and Bodies modules needed to quickly create a simple 2D physics world with rigid bodies in your project.

Does Matter.js handle constraints and springs for physics-based visualizations?▼

Matter.js handles constraints and springs for physics-based visualizations by allowing you to attach rigid bodies together, simulating realistic joint movements and elastic forces in 2D environments.

When should I not use a 2D rigid-body physics engine for web simulations?▼

You should not use a 2D rigid-body physics engine when your web simulation requires 3D spatial dynamics or non-rigid soft body deformations, as these fall outside the scope of standard 2D rigid-body constraints.
