Transform.root

public Transform root;

Descripción

Returns the topmost transform in the hierarchy.

(This never returns null, if this Transform doesn't have a parent it returns itself.)

	// Is a collision between two objects in different hierarchies?
	function OnCollisionEnter(collision : Collision) {
		if ( collision.transform.root != transform.root ) {
			print("The colliding objects are not in the same hierarchy");
		}
	}

        if (collision.transform.root != transform.root)
            print("The colliding objects are not in the same hierarchy");
        
    }
