Please update Flagrush Tutorial Lesson 14 in wiki :)

Please Help me I'm going to study Game Programming and I going adapt Flagrush Tutorial for my Game.



I have many problem about Collision



It doesn't Work when I Load 3ds Charactor CollisionResults can't check  :?

I write this in InitGame()


CollisionTreeManager.getInstance().setTreeType(CollisionTree.AABB_TREE);
results = new TriangleCollisionResults();


And Write This to Update()
results.clear();
n1.findCollisions(n2, results);

if (results.getNumber() > 0) {

                             
              System.out.println("Hello Collision");
           
                        }


and build player with 3ds
       

      private void buildPlayer(){
      Node model = null;
    n1 = new Node("Node 1 for collision");
        try {
        MaxToJme C1 = new MaxToJme();
        ByteArrayOutputStream BO = new ByteArrayOutputStream();
            URL maxFile = Level4Again.class.getClassLoader().getResource("Model/zaara.3ds");
            C1.convert(new BufferedInputStream(maxFile.openStream()),BO);
            model = (Node)BinaryImporter.getInstance().load(new ByteArrayInputStream(BO.toByteArray()));
           
        model.setModelBound(new BoundingBox());
            model.updateModelBound();
       
            //scale it to be MUCH smaller than it is originally
            model.setLocalScale(.01f);
     } catch (IOException e) {
            logger.throwing(this.getClass().toString(), "buildPlayer()",
                            e);
        }

        //set the vehicles attributes (these numbers can be thought
        //of as Unit/Second).
        player = new Vehicle("Player Node", model);
        player.setLocalScale(10);
        ((Vehicle) player).setAcceleration(6);
        ((Vehicle) player).setBraking(6);
        ((Vehicle) player).setTurnSpeed(2);
        ((Vehicle) player).setWeight(15);
        ((Vehicle) player).setMaxSpeed(10);
        ((Vehicle) player).setMinSpeed(2);
       
        player.setLocalTranslation(new Vector3f(100,0, 100));
        n1.attachChild(player);
       
        scene.attachChild(player);
        scene.updateGeometricState(0, true);
        player.setRenderQueueMode(Renderer.QUEUE_OPAQUE);
}


and build model from class village

private void buildVillage(){
n2 = new Node("Node 2 for collision");
t = new Village();
        t.buildTower("Tower2","Model/Tower.3ds");
        t.setLocalScale(2);
        t.setLocalTranslation(new Vector3f(105,0,50));
        n2.attachChild(t);
        scene.attachChild(n2);}


When player walk near Node n2 Why if (results.getNumber() > 0) {}   not work ?
Sorry my english is bad.
