centerY = (CAMERA_HEIGHT - this.mSpriteATextureRegion.getHeight()) / 2;
final FixtureDef objectFixtureDef = PhysicsFactory.createFixtureDef(0,
0.5f, 0.5f);
spriteA= new Sprite(centerX, centerY, this.mSpriteATextureRegion);
body = PhysicsFactory.createBoxBody(mPhysicsWorld, spriteA,
BodyType.DynamicBody, objectFixtureDef);
mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(spriteA,
body, true, true));
final PhysicsHandler physicsHandler = new PhysicsHandler(spriteA);
spriteA.registerUpdateHandler(physicsHandler);
