Getting object position in screen coordinates
I have a user moving an avatar from the 3rd person view (moving arms/hands).
I want to check if the avatars hand is 'on top' of an on object from the view of the user, is there a way to get the projection transformation matrix and apply that to the object positions to get the screen coordinates of both objects then compare them?

Search the documentation for "worldToScreen", there should be a few examples showing how to convert a 3d location to a 2d location.
