Abstract base class for in-between interpolation handlers; parent class of Tween.

Summary

Properties

View all inherited from Instance
View all inherited from Object

Methods

  • Cancel():()

    Halts playback and resets the tween variables. If you then call TweenBase:Play(), the properties of the tween resume interpolating towards their destination, but take the full length of the animation to do so.

  • Pause():()

    Halts playback of the tween. Doesn't reset its progress variables, meaning that if you call TweenBase:Play(), the tween resumes playback from the moment it was paused.

  • Play():()

    Starts playback of a tween. Note that if playback has already started, calling Play() has no effect unless the tween has finished or is stopped (either by TweenBase:Cancel() or TweenBase:Pause()).
