libGDX Box2D Physics

Quick reference for the libGDX Box2D JNI wrapper (com.badlogic.gdx.physics.box2d.*). Covers World, Body, Fixture, Shape, filtering, contacts, joints, debug rendering, and the PPM pattern.

Units — Box2D Works in Meters

Box2D is tuned for objects 0.1–10 meters. Using pixel coordinates causes sluggish movement (internal velocity cap is 2 units/timestep).

Approach 1 — PPM constant:

public static final float PPM = 100f; // 100 pixels = 1 meter

// Creat
