Class Shape

java.lang.Object
  com.badlogic.gdx.physics.box2d.Shape

Direct Known Subclasses:

ChainShape, CircleShape, EdgeShape, PolygonShape

public abstract class Shape
extends java.lang.Object

A shape is used for collision detection. You can create a shape however you like. Shapes used for simulation in b2World are created automatically when a b2Fixture is created. Shapes may encapsulate a one or more child shapes. NOTE: YOU NEED TO DISPOSE SHAPES YOU CREATED YOURSELF AFTER YOU NO LONGER USE THEM! E.g. after calling body.createFixture();
