What problem does it solve? Building realistic physics in Phaser games by hand means writing O(n²) collision loops, manual gravity integration, and custom joint logic. This Skill provides structured guidance for using Phaser's Matter.js integration to create realistic bodies, constraints, and collision handling without reinventing a physics engine. ## Core Features & Use Cases - Body Creation: Configure rectangles, circles, polygons, and compound bodies with bounce, friction, density, and static/sensor states. - Constraints & Joints: Build chains, ropes, springs, and hinges using Matter constraints, including multi-plank bridge construction. - Collision Events: Label bodies and listen to collisionstart events to trigger game logic like coin collection. - Use Case: You are building a physics puzzle game where the player topples stacked crates onto targets. Use this Skill to create a stable box pyramid with tuned friction and density, then detect collisions via labeled bodies to score hits. ## Quick Start Ask the AI to set up a Phaser 3 scene with Matter physics containing a bouncing ball, a static ground, and a rope made of constrained links.
