This demo shows a very basic setup for a two player "split screen" camera mode. In the demo you have two players ( a blue ship and a red ship) that are controlled independently and are placed at opposite ends of the room. Both player ships have their own view port and camera assigned to them, and the views will follow each player ship independently.
Controls for P1 are WASD to move and Space to shoot, while P2 controls are Arrow Keys to move and Numpad0 to shoot.
Cameras are set up in the "o_camera" object Create event, and the HUD is drawn in the "o_game" object Draw event.
