Collision between two objects

[Kumaraswamy]

I am new to 3d models and handling them, I want to know if there are any examples to detect collision between two objects? 

So far I have tried

First model:

Code: [Select]

object3D.setCollisionMode(Object3D.COLLISION_CHECK_OTHERS | Object3D.COLLISION_CHECK_SELF);
        object3D.addCollisionListener(new CollisionListener() {
            @Override
            public void collision(CollisionEvent collisionEvent) {
                Log.d("Renderer", "collision: " + collisionEvent);
            }

            @Override
            public boolean requiresPolygonIDs() {
                return false;
            }
        });

And

Code: [Select]

((MyModel) mymodel).getObject3D().setCollisionMode(Object3D.COLLISION_CHECK_OTHERS | Object3D.COLLISION_CHECK_SELF);
        ((MyModel) mymodel).getObject3D().addCollisionListener(new CollisionListener() {
            @Override
            public void collision(CollisionEvent collisionEvent) {
                Log.d("Model3d", "collision: " + collisionEvent);
            }

            @Override
            public boolean requiresPolygonIDs() {
                return false;
            }
        });
        SimpleVector vector = new SimpleVector();
        vector.y = 10;
        ((MyModel) mymodel).getObject3D().checkForCollision(vector, 100);

So far, the event is not triggered 
Am I missing something?

How do I listen to collisions?

You have to enable collisions on the object to be registered. Maybe this helps: https://www.jpct.net/wiki/index.php?title=Collision_detection
