Now, we will create the previously listed Java files as follows:

1. Add the following code to MyBulletInterface.java :

public interface MyBulletInterface extends Disposable {

public void init();

public void update(float delta);

public void remove(btRigidBody body);

public btDiscreteDynamicsWorld getWorld();

}

2. Add the following code to BulletWorld.java :

public class BulletWorld implements MyBulletInterface {
protected btDefaultCollisionConfiguration
collisionConfiguration;
protected btCollisionDispatcher dispatcher;
protected btDbvtBroadphase broadphase;
protected btSequentialImpulseConstraintSolver solver;
protected btDiscreteDynamicsWorld world;

protected BulletWorld() {

}

@Override
public void init() {
Bullet.init();
collisionConfiguration = new
btDefaultCollisionConfiguration();
dispatcher = new btCollisionDispatcher(collisionConfigur
ation);
broadphase = new btDbvtBroadphase();
solver = new
btSequentialImpulseConstraintSolver();
world = new btDiscreteDynamicsWorld(dispatcher,
broadphase, solver, collisionConfiguration);
world.setGravity(new Vector3(0, -9.81f, .1f));

}
