如何在Slick2D中使用JBox2D调试绘图？

Question

JBox2D , the Java port of the Box2D physics engine, features an extensible module for creating debug drawing of shapes. How can I use this with the Slick2D game library?

Answer 1

Using the JBox2D DebugDraw class for Slick2D it is simple to add debug drawing. Put the below code in your init method:

Slick2DJBox2DDebugDraw debugDraw = new Slick2DJBox2DDebugDraw(gameContainer);
debugDraw.setFlags(DebugDraw.e_shapeBit);
world.setDebugDraw(debugDraw); // Where world is your JBox2D world
