Résumé
Propriétés
Propriété de lecture seule qui montre l'état actuel de l'animationsTween.
Méthodes
Arrête la lecture et réinitialise les variables d'adolescent.Si vous appelez ensuite TweenBase:Play(), les propriétés de l'adolescent reprennent l'interpolation vers leur destination, mais prennent toute la longueur de l'animation pour le faire.
Arrête la lecture du tween.Ne réinitialise pas ses variables de progression, ce qui signifie que si vous appelez TweenBase:Play(), le préadolescent reprend le jeu à partir du moment où il a été interrompu.
Démarre la lecture d'un tween.Notez que si la lecture a déjà commencé, l'appel de Play() n'a aucun effet à moins que le pré-adolescent n'ait fini ou ne soit arrêté (par TweenBase:Cancel() ou TweenBase:Pause() ).
Évènements

In this example a part is rotated by a Tween back and forth several times. The TweenInfo in this case is configured to make the tween repeat twice after the first playback and pause between each playback. A function is connected to when the tween's PlaybackState changes. When run, this function will fire whenever the tween starts, pauses between playback, and ends.
local TweenService = game:GetService("TweenService")
local part = Instance.new("Part")
part.Position = Vector3.new(0, 10, 0)
part.Anchored = true
part.Parent = workspace
local goal = {}
goal.Orientation = Vector3.new(0, 90, 0)
local tweenInfo = TweenInfo.new(1, Enum.EasingStyle.Quad, Enum.EasingDirection.InOut, 2, true, 0.5)
local tween = TweenService:Create(part, tweenInfo, goal)
local function onPlaybackChanged()
print("Tween status has changed to:", tween.PlaybackState)
end
local playbackChanged = tween:GetPropertyChangedSignal("PlaybackState")
playbackChanged:Connect(onPlaybackChanged)
tween:Play()Méthodes
Cancel
Arrête la lecture d'un Tween et réinitialise les variables d'adolescent.
Ne réinitialise que les variables d'adolescent, pas les propriétés modifiées par l'adolescent.Si vous annulez un tween au milieu de son animations, les propriétés ne sont pas réinitialisées à leurs valeurs d'origine.Diffère de TweenBase:Pause() en ce sens qu'une fois repris, il prend la durée complète de l'adolescent pour terminer l'animations.

This sample demonstrates the impact of cancelling a tween.
A part is instanced in the Workspace and a tween is set up to move it along the Y axis. Mid way through the tween, it is cancelled. It can be observed here that the part does not return to its original position, but when it is resumed it takes the full length of the tween (5 seconds) to complete.
This is the key difference TweenBase:Pause() and TweenBase:Cancel().
local TweenService = game:GetService("TweenService")
local part = Instance.new("Part")
part.Position = Vector3.new(0, 10, 0)
part.Anchored = true
part.Parent = workspace
local goal = {}
goal.Position = Vector3.new(0, 50, 0)
local tweenInfo = TweenInfo.new(5)
local tween = TweenService:Create(part, tweenInfo, goal)
tween:Play()
task.wait(2.5)
tween:Cancel()
local playTick = tick()
tween:Play()
tween.Completed:Wait()
local timeTaken = tick() - playTick
print("Tween took " .. tostring(timeTaken) .. " secs to complete")
-- The tween will take 5 seconds to complete as the tween variables have been reset by tween:Cancel()Pause
Arrête la lecture du tween.Ne réinitialise pas ses variables de progression, ce qui signifie que si vous appelez TweenBase:Play(), le préadolescent reprend le jeu à partir du moment où il a été interrompu.
Si vous voulez réinitialiser les variables de progression du tween, utilisez TweenBase:Cancel() .
Vous ne pouvez suspendre que les adolescents qui se trouvent dans le PlaybackState de Enum. PlaybackState.Playing ; les adolescents dans d'autres états ne s'arrêteront pas.Si un adolescent est dans un autre PlaybackState tel que Enum. PlaybackState.Delayed (en raison de son TweenInfo.DelayTime étant supérieur à 0), l'essai de pause du adolescent échouera et le adolescent jouera après son temps de pause spécifié.

This sample demonstrates how the playback of a tween can be paused and resumed.
A part is instanced in the Workspace and a tween is setup that will move it 50 studs along the X axis. However during playback the tween is briefly paused, then resumed. To further illustrate this the BrickColor of the part changes from red to green while it is paused.
local TweenService = game:GetService("TweenService")
local part = Instance.new("Part")
part.Position = Vector3.new(0, 10, 0)
part.Anchored = true
part.BrickColor = BrickColor.new("Bright green")
part.Parent = workspace
local goal = {}
goal.Position = Vector3.new(50, 10, 0)
local tweenInfo = TweenInfo.new(10, Enum.EasingStyle.Linear)
local tween = TweenService:Create(part, tweenInfo, goal)
tween:Play()
task.wait(3)
part.BrickColor = BrickColor.new("Bright red")
tween:Pause()
task.wait(2)
part.BrickColor = BrickColor.new("Bright green")

Démarre la lecture d'un tween.Notez que si la lecture a déjà commencé, l'appel de Play() n'a aucun effet à moins que le pré-adolescent n'ait fini ou ne soit arrêté (par TweenBase:Cancel() ou TweenBase:Pause() ).
Plusieurs adolescents peuvent être joués sur le même objet en même temps, mais ils ne doivent pas animer la même propriété.Si deux adolescents tentent de modifier la même propriété, le tween initial est annulé et remplacé par le tween le plus récent (voir exemples).

In this example a Tween is created to animate the position and color of a Part. Because the position and color are part of the same tween, they will change at the exact same rate and will reach their goal at the same time.
local TweenService = game:GetService("TweenService")
local part = Instance.new("Part")
part.Position = Vector3.new(0, 10, 0)
part.Color = Color3.new(1, 0, 0)
part.Anchored = true
part.Parent = game.Workspace
local goal = {}
goal.Position = Vector3.new(10, 10, 0)
goal.Color = Color3.new(0, 1, 0)
local tweenInfo = TweenInfo.new(5)
local tween = TweenService:Create(part, tweenInfo, goal)
tween:Play()This code sample includes a demonstration of tween conflict. A part is instanced in the Workspace, and two tweens are created that attempt to move the part in conflicting directions.
When both tweens are played, the first tween is cancelled and overwritten by the second tween. This can be seen as the part moves along the Y axis as opposed to the Z axis.
To further demonstrate this, connections have been made for both tweens to the Tween.Completed event. Upon playing the tweens, the following is printed.
tween1: Enum.PlaybackState.Cancelled tween2: Enum.PlaybackState.Completed
These prints show that the first tween was cancelled (firing the Completed event) immediately upon the second tween being played. The second tween then went on to play until completion.
local TweenService = game:GetService("TweenService")
local part = Instance.new("Part")
part.Position = Vector3.new(0, 10, 0)
part.Anchored = true
part.Parent = game.Workspace
local tweenInfo = TweenInfo.new(5)
-- create two conflicting tweens (both trying to animate part.Position)
local tween1 = TweenService:Create(part, tweenInfo, { Position = Vector3.new(0, 10, 20) })
local tween2 = TweenService:Create(part, tweenInfo, { Position = Vector3.new(0, 30, 0) })
-- listen for their completion status
tween1.Completed:Connect(function(playbackState)
print("tween1: " .. tostring(playbackState))

In this example the walkspeed of any player joining the game will be slowed to 0 over 10 seconds using a Tween. The Completed event is used to reset the walkspeed after the Tween has finished playing.
local Players = game:GetService("Players")
local TweenService = game:GetService("TweenService")
local SLOW_DURATION = 10
local function slowCharacter(humanoid)
local goal = {}
goal.WalkSpeed = 0
local tweenInfo = TweenInfo.new(SLOW_DURATION)
local tweenSpeed = TweenService:Create(humanoid, tweenInfo, goal)
tweenSpeed:Play()
return tweenSpeed

local humanoid = character:WaitForChild("Humanoid")
local initialSpeed = humanoid.WalkSpeed

tween1:Play()
tween2:Play()This code sample includes an example of how Tween.Completed can be used to determine if a Tween has been successfully completed, or cancelled.
In this case a part is instanced and tweened towards 0, 0, 0. Once the tween has completed, if the final PlaybackState is Completed then the part will explode. Were the tween to be cancelled prior to completion, the explosion would not be created.
This method can be used to link tweens to other effects, or even chain several tweens to play after each other.
