when you're making a film, first person head bob normally would need to be done by shaking the mouse. why not instead have head bob as though the player's head actually bobs.
now, I don't mean bouncing up and down, that'd be ridiculous. what i mean is if head bob uses the effect that occurs when using the test explosions/any explosions happening near the player/the player falls. i guess it would intensify as the player got faster, but only when the feet are touching the ground/bricks.
