Beginner Question: Timedelta() use

Hello Everyone:

I was able to find out info from the wiki that if you use the “force” command, then you do not have to adjust/use Timedelta() since force already takes that into affect.

How about when rotating sprites, do you use timedelta() for rotating or not?

Essentially, I was only able to find 1 example of when not to use timedelta(), but i dont exactly know when to use it and when to not use it.

do you use if for rotating sprites or camera movement?

Any help would be greatly appreciated.
