The title might be a litle confusing.
But what I want to do is by using “Ray collision detection” to pick and interact with a node on the scene.
The interaction from the node is defined in my LifeFormObject class that extends PhysicsCharacterNode!
So what I initially did was.
CollisionResult closestTarget = targets.getClosestCollision();
closestTarget.getGeometry().getParent(); this would return a node ( Node ).
This is actually pretty good, for my basic needs!
Then I tried to cast the node that I got up to (LifeFormObject) to be able to call it’s interact() method.
but that broke!
So what I wonder is how you guys would approach this problem?
// Krol
Never mind this 
I figured out the easy solution!
(LifeFormObject)interactables.getChild(closestTarget.getGeometry().getParent().getName());
Don’t know if this is “THE” solution, but it’s working pretty nice for my prototype…
