Using the above setup we can create a Duration variable that is accessible to be exposed for easy tweaking of the playback of any timeline. The Target of the Set Play Rate should be the Timeline itself, dragged in from the components list. An example of usage would be to set the Duration to a higher value, thereby slowing the playback of the Timeline by increasing its duration.
Timeline Key Points and Concepts
Timelines can act as essentially On Tick operators.
Update — Will do the following throughout the update period. Reverse will reverse the update from the point the timeline stops. If you want to update from the end of the timeline, then do so.
Finished — Will do the following after the update period. Play direction does not matter, this will always happen after the update.
Direction — Drag off and add an ETimeline Direction switch to determine which direction (forwards or backwards) the timeline is playing.
