AnimationTimeIndex
is an option to Animator and related functions that specifies the current time index for the animator.
Details
- AnimationTimeIndex runs from 0 to the duration of the animation, in seconds.
- AnimationTimeIndex is 0 at the animator's minimum value and duration at the maximum.
- The typical default setting of AnimationTimeIndex -> Automatic will calculate the appropriate value from the animation.
- While Animator[Dynamic[var],…] is running, changing var outside the animator will have no effect on AnimationTimeIndex.
- AnimationTimeIndex varies continuously, even for discrete animations.
- AnimationDirection has no impact on AnimationTimeIndex.

Changing the DefaultDuration will change the maximum time index:

Interactively changing a paused animator will also change the value of AnimationTimeIndex:

Possible Issues (1)Common pitfalls and unexpected behavior
To change a running animator programmatically, change the value of AnimationTimeIndex, not the animation variable:
