              KX_Scene

An active scene that gives access to objects, cameras, lights and scene attributes.

The activity culling stuff is supposed to disable logic bricks when their owner gets too far from the active camera. It was taken from some code lurking at the back of KX_Scene - who knows what it does!

       import GameLogic
       
       # get the scene
       scene = GameLogic.getCurrentScene()
       
       # print all the objects in the scene
       for obj in scene.objects:
               print obj.name
       
       # get an object named 'Cube'
       obj = scene.objects["OBCube"]
       
       # get the first object in the scene.
       obj = scene.objects[0]

       # Get the depth of an object in the camera view.
       import GameLogic
       
       obj = GameLogic.getCurrentController().owner
       cam = GameLogic.getCurrentScene().active_camera
       
       # Depth is negative and decreasing further from the camera
       depth = obj.position[0]*cam.world_to_camera[2][0] + obj.position[1]*cam.world_to_camera[2][1] + obj.position[2]*cam.world_to_camera[2][2] + cam.world_to_camera[2][3]
