Do you want the camera show more of the right screen when player moving right and the same idea when moving left?
If you only want the camera to be bit slow, do this:
Add a sprite and name it camera and add scroll to behavior
Every tic : camera set position to : lerp(self.X,Player.X,6*dt) - lerp(self.Y,Player.Y,6*dt)
Change the number "6" until you achieved what you want.
