Matter.js JavaScript Physics
Matter.js is a JavaScript physics engine for 2D. You define bodies (circles, rectangles, polygons), set properties (mass, friction, restitution), and Matter.js simulates interactions: gravity pulls things down, bodies collide realistically, constraints keep things together. Use cases: games, interactive visualizations, educational simulations, physics demos. Mastery takes 3-4 weeks. Specialists earn 5-10% premium for interactive, engaging experiences. The skill sits between game development and web development.
什麼是 Matter.js JavaScript Physics
Matter.js is a 2D rigid-body physics engine written in JavaScript. You create physics objects (bodies) with properties like mass, friction, and velocity. Matter.js simulates interactions: gravity, collisions, constraints (joints). You render bodies to Canvas or WebGL and users see realistic motion. A simple example: create a box (body), set gravity to 9.8 m/s², drop it. Matter.js computes position each frame. Box falls realistically, bounces off ground (if restitution > 0), gradually stops (if friction > 0).
