Troubleshooting General Help

Hi try to undertsand collision; I used that code to know if my pointer touch a sphere.I noticed that collisionSphere is equal to TWO but my pointer touche the sphere in one point

Why that?

[java]Vector3f origin = getCamera().getWorldCoordinates(

getInputManager().getCursorPosition(), 0.0f);

Vector3f direction = getCamera().getWorldCoordinates(

getInputManager().getCursorPosition(), 0.3f);

direction.subtractLocal(origin).normalizeLocal();

Ray ray = new Ray(origin, direction);

CollisionResults results = new CollisionResults();

int collisionSphere = sphere.collideWith(ray, results);[/java]

because you have a collision result each time the ray hit a polygon, so one for the front side and one for the back side of the sphere

with a box it’s the same i think.

Or i should use other code?
