Tween

Inherits from: TweenBase → Instance → Object

The Tween object controls the playback of an interpolation. Creating and configuring a Tween is done with the TweenService:Create() function; Instance.new() cannot be used for this particular object.

Note that while the configuration of a tween can be accessed after a tween has been created, it can not be modified. If new goals are needed for an interpolation, a new Tween must be created.

Also note that multiple tweens can be played on the same object at the same time, but they must not be interpolating the same property. If two tweens attempt to modify the same property, the initial tween will be cancelled and overwritten by the most recent tween.

Methods

Inherited from TweenBase

NameType / ReturnsDescription
TweenBase: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.
TweenBase: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.
TweenBase: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()).
