i’m doing a project about car animation,
1? - how do i make the wheel to spin alot, like it’s moving
2? - how can i make the background move from right to left over and over again, like car motion moving.

1.make wheel, after a few frames, insert keyframe, select motion tween/rotation.
when used, this clip will constantly rotate (the wheel is a clip)
