public abstract class Shape
extends 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();
