So I've noticed in lots of animations, when a person is inside a moving car, they follow the rumbling motion the car makes as the engine is vibrating and the car is moving and the background is constantly moving in one direction. And I've been studying different animations of the vibrating effect and I'm still struggling understanding how to create that effect, so I figured I'd post it on here to get some help. Any advice would help and thanks!
Put everything in a moveclip or graphic symbol, wiggle it up and down a little bit.
