Updates all tweens started on individual items and chains. The time value allows you to control how quickly the tweens advance, and in most cases the result of GetFrameTime should be used. The time can be set negative so that any playing tweens will play in reverse until they reach their start points, however they will not stop playing when they reach the beginning and will instead wait for the time to become positive again or wait for you to stop them manually.
