Adding animation (using AnimationFactory ) to physical Node

I have physical object and everything works well until I add to it animation. After it it’s not rigid anymore, and other objects can go through ir, here is the code how I add animation. Do you have any suggestions how to make it rigid? Or what is the problem?

    float[] knots = {0.0f, 0.4f, 0.5f, 0.9f, 1.0f };
    // Transform[] transforms = new Transform[knots.length];
    Transform[] transform = new Transform[knots.length];
    transform[0] = new Transform(new Vector3f(0.0f, 2.0f, 5.0f),
         new Quaternion(0.0f, 0.0f, 0.0f, 1.0f)    , Vector3f.UNIT_XYZ);
   transform[1] = new Transform(new Vector3f(0.0f, 2.0f, 200.0f),
            new Quaternion(0.0f, 0.0f, 0.0f, 1.0f), Vector3f.UNIT_XYZ);
   transform[2] = new Transform(new Vector3f(0.0f, 2.0f, 200.0f),
            (new Quaternion().fromAngleAxis(FastMath.PI, new Vector3f(0, 1, 0))), Vector3f.UNIT_XYZ);
   transform[3] = new Transform(new Vector3f(0.0f, 2.0f, 5.0f),
           new Quaternion().fromAngleAxis(FastMath.PI, new Vector3f(0, 1, 0)), Vector3f.UNIT_XYZ);
   transform[4] = new Transform(new Vector3f(0.0f, 2.0f, 5.0f),
            (new Quaternion().fromAngleAxis(2*FastMath.PI, new Vector3f(0, 1, 0))), Vector3f.UNIT_XYZ);
    // Time duration for the animation
    float animTime = 30;
    // Frames per second for the animation
    int fps = 60;
    AnimationFactory animFactory = new AnimationFactory(animTime, "OtoPath", fps);
     for (int i = 0; i < knots.length; i++) {
        // Add the knot to the AnimationFactory
        animFactory.addTimeTransform(knots[i] * animTime, transform[i]);
     // Build the animation
    Animation anim = animFactory.buildAnimation();
    // Create control for the spatial animation
    AnimControl control = new AnimControl();
    // Hashmap of available animations
    HashMap<String, Animation> animations = new HashMap<String, Animation>();
    animations.put("OtoPath", anim);
    // Add control to target spatial
    // Create channel for the animation, that enables us to play the animation
    AnimChannel channel = control.createChannel();   
    channel.setLoopMode(LoopMode.Loop); [/java] 

and this is the node itself

Oto = (Node) assetManager.loadModel(“Models/Oto/Oto.mesh.xml”);
Oto.move(new Vector3f(0, 2, 5));
CollisionShape shape = CollisionShapeFactory.createDynamicMeshShape(Oto);
Oto.addControl(new RigidBodyControl(shape, 1));

What do you mean by rigid? Because I don’t think it means what you think it means…

I mean before I added animation to Oto, physical Node could not go through it, there was collision, one object pushed another and so on. after adding it, physical object is not colliding with it, and it can go through it. The most interesting part is that I have enabled to see physics doing


and I see how collision shapes go through each other, but it was not so before adding animation

never used the AnimationFactory, but if it’s just a Spatial animation, then you can set oto’s RigidBody control to kinematic

Thanks for advice, Here is what I did

CollisionShape shape = CollisionShapeFactory.createDynamicMeshShape(Oto);
RigidBodyControl rb = new RigidBodyControl(shape, 1);

and it works perfectly
