where should be player on if many node under player?

h3dCastRay argument 1 is node to check,
what node is chosen in case of picture.

Hi.

h3dCastRay (node, ...) searches node and all of node's children recursively for intersection.
So, if you can't guarantee that the nodes you want to intersect with are below a certain GroupNode, you will
have to specify H3DRootNode as starting node for the raycast. Then you will get all intersected nodes (within the ray's length)
