Tween

Show deprecated

Tweens are used to interpolate the properties of instances. The Tween object itself controls the playback of the interpolation. Creating and configuring tweens is done with the TweenService/Create function. This is the only way to create tweens. 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 interpolation, a new tween must be created. Further information on how to create Tweens can be found on the TweenService page.

Multiple tweens can be played on the same object at the same time, but they must not be animating 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 (see examples).

Although other methods exist for tweening objects, such as GuiObject/TweenSizeAndPosition, Tweens allows multiple properties to be modified and for the animation to be paused and cancelled at any point.

Properties

Instance

Instance

[ReadOnly] [NotReplicated]

The read-only Instance property of a Tween points to the Instance whose properties are being interpolated by the tween.

TweenInfo

TweenInfo

[ReadOnly] [NotReplicated]

Read-only property that includes information on how the interpolation of the Tween is to be carried out, using the TweenInfo data type.

Inherited from TweenBase: Show Hide

PlaybackState

PlaybackState

[ReadOnly] [NotReplicated]

Read only property that shows the current playback Enum/PlaybackState of the Tween.

Inherited from Instance: Show Hide

int

DataCost

[ReadOnly] [NotReplicated]

The cost of saving the instance using data persistence.

Instance

Parent

Determines the hierarchical parent of the Instance.

bool

RobloxLocked

If true, the Instance and its descendants cannot be indexed or edited by a Script or LocalScript and will throw an error if it is attempted.

string

ClassName

[ReadOnly] [NotReplicated]

A read-only string representing the class this Instance belongs to.

string

Name

A non-unique identifier of the Instance.

bool

Archivable

Determines if an Instance can be cloned using /Instance/Clone or saved to file.

Functions

Inherited from TweenBase: Show Hide

void

Play ( )

The Play function starts the playback of its Tween. Note that if a tween has already begun calling Play will have no effect unless the tween has finished or has been stopped (either by TweenBase/Cancel or TweenBase/Pause).

void

Pause ( )

The Pause function halts playback of its Tween. If TweenBase/Resume is called again the tween will resume playback from the moment it was paused.

void

Cancel ( )

The Cancel function halts playback of its Tween and resets the tween variables. If TweenBase/Play is called again the Tween's properties will resume interpolating towards their destination but, as the tween variables have been reset, take the full length of the animation to do so.

Objects

GetChildren ( )

Returns an array containing all of the Instance's children.

void

Destroy ( )

Sets the Instance/Parent property to nil, locks the Instance/Parent property, disconnects all connections and calls Destroy on all children.

Instance

FindFirstChild ( string name , bool recursive )

Returns the first child of the Instance found with the given name.

RBXScriptSignal

GetPropertyChangedSignal ( string property )

Get an event that fires when a given property of an object changes.

string

GetFullName ( )

Returns a string describing the Instance's ancestry.

Instance

FindFirstChildWhichIsA ( string className , bool recursive )

Returns the first child of the Instance for whom Instance/IsA returns true for the given className.

Array

GetDescendants ( )

[CustomLuaState]

Returns an array containing all of the Instance's descendants.

bool

IsAncestorOf ( Instance descendant )

Returns true if an Instance is an ancestor of the given descendant.

bool

IsDescendantOf ( Instance ancestor )

Returns true if an Instance is a descendant of the given ancestor.

Instance

FindFirstChildOfClass ( string className )

Returns the child of the Instance with the given name. If the child does not exist, it will yield the current thread until it does.

string

GetDebugId ( int scopeLength )

[NotBrowsable]

Returns a coded string of the Instances DebugId used internally by Roblox.

Instance

Clone ( )
