Take the object position (object->GetMovable ()->GetFullPosition ()) then transform it to camera space using the camera->GetTransform(). Then using iCamera->Perspective() you can convert that to screen space. > > 2. So far I have been creating all my entities in Blender2CS and running > the game from there.

If you load that plugin then you can go to it by using tab (by default) and then you can do various things like show all entities. Type 'help' in the celconsole to see what commands you have. > > 3.
