You can simply change the position of the camera with the triggers in the camera section of the triggers, like camera position and camera properties. Nothing special, mostly just create a camera in world editor that's in the exact spot you want it, then in the beggining of the map apply the game camera to that camera, then just every .01 or whatever seconds pan the camera to the position of the unit and change the facing of the camera to that of the unit. |
