Start the example mission, on a hint you will have the CursorTarget, Supplycrate in a 20 Unit radius and the distance to that crate with an updateratio of 5 per secound.
Try to get the create in cursortarget it will take some time, for references there are two other objects near to create that will recognize just right after missionstart.
Distance to the crate will stay way to far for ever.
