Just finished an Offset Camera behaviour with the help of Meestar.
Although I needed this for my game, its a handy behaviour for anyone that wants the camera to be 'ahead' of the player so they can see more of whats to come. It will smoothly switch directions and centre on the screen when not moving. It has a couple of attributes to set the offset amount and the speed of the offset movement.
Anyhow, thought Id mention it, as I dont recall seeing a camera behaviour like this one before. Is now up on 3.0 forge at moment.
