Description
Returns how many times the given ray intersects the given sphere.
RayCastSphereIntersect returns an integer number representing how many times the ray given through its position and direction intersects the given sphere. If the ray does not intersect the sphere, RayCastSphereIntersect returns 0. Otherwise RayCastSphereIntersect may return 1 (the ray intersects the sphere in exactly one point) or 2 (the ray intersects the sphere in two points--enters and exits the surface of the sphere).
