Previously the distance constraint actuator was always working in local axis. The local flag allows to cast the ray along a world axis (when the flag is not selected). The N flag works differently in this case: only the object orientation is changed to be parallel to the normal at the hit point. The linear velocity is now changed so that the speed along the ray axis is null. This eliminates the need to compensate the gravity when casting along the Z axis.
