How do i make the player roll to a maxium of 20º while the player is panning? The player must also roll to the side the player is panning.

my.pan = ((1 - (SmoothSpeed / 25) * time_step) * (my.pan - camera.pan) + camera.pan); // This is the code used to pan the player.

Thanks.

You'll need to find the change in speed, not just the speed. If your speed changes, then you want to roll (I suppose).

my.roll = clamp( my.roll + changeOfSpeed * time_step, -20, 20 )
