I have a full 2D environment, with sprites going around as landscape, characters, etc.
To make it more state-of-art looking, I want to implement a motion blur effect, similar to modern FPS games (i.e. Crysis) blur when moving the camera quickly.
In a sidescroller, the desired effect is having this slight blur appearing to give the idea of fast movement when the camera is moving. If anyone could give me some tips on doing this, I'm assuming in a pixel shader, I'd be grateful.
