Metode

  • Cancel():void

    Menghentikan pemutar dan mengatur ulang variabel tween. Jika Anda kemudian memanggil TweenBase:Play(), proporsi tween mereka berakhir setelah interpolasi ke tujuan mereka, tetapi ambil panjang animasi untuk melakukannya.

  • Pause():void

    Menghentikan pemutar tween. Tidak mengatur ulang variabel kemajuan tween, yang berarti bahwa jika Anda memanggil TweenBase:Play(), tween akan melanjutkan pemutaran dari saat tertunda.

  • Play():void

    Memulai pemutaran tween. Catat bahwa jika pemutaran telah dimulai, menelepon Play() tidak berpengaruh kecuali tween telah selesai atau dihentikan (untuk menghentikan, TweenBase:Cancel() atau Class.TweenBase:Pause()).

Contoh Kode

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.

Tween PlaybackState
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)

Metode

Cancel

void

Menghentikan pemutaran dari Tween dan mengatur ulang variabel tween.

Hanya mengatur ulang variabel tween, bukan properti yang diubah oleh tween. Jika Anda menyetel ulang tween setengah melalui animasi, properti tidak akan diatur ulang ke nilai aslinya. Berbeda dari TweenBase:Pause() di mana setel ulang, durasi tween penuh diperlukan untuk menyelesaikan animasi.

Contoh Kode

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().

Tween 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

void

Menghentikan pemutar tween. Tidak mengatur ulang variabel kemajuan tween, yang berarti bahwa jika Anda memanggil TweenBase:Play(), tween akan melanjutkan pemutaran dari saat tertunda.

Jika Anda ingin mengatur ulang variabel kemajuan tween, gunakan TweenBase:Cancel() .

Anda hanya dapat menghentikan tweens yang berada dalam PlaybackState dari Enum. PlaybackState.Playing ; tweens di neg

Contoh Kode

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.

Pausing a Tween
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")

tween:Play()

Play

void

Memulai pemutaran tween. Catat bahwa jika pemutaran telah dimulai, menelepon Play() tidak berpengaruh kecuali tween telah selesai atau dihentikan (untuk menghentikan, TweenBase:Cancel() atau Class.TweenBase:Pause()).

Beberapa remaja dapat dimainkan pada objek yang sama pada saat yang sama, tetapi mereka tidak boleh menganimasikan properti yang sama. Jika dua remaja mencoba untuk mengubah properti yang sama, tween awal dibatalkan dan ditulis ulang oleh tween terbaru (lihat contoh).

void

Contoh Kode

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.

Tween Creation
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.

Tween Conflict
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))

end)

tween2.Completed:Connect(function(playbackState)

	print("tween2: " .. tostring(playbackState))

end)



-- try to play them both

Acara

Completed

Dibakar saat tween selesai bermain atau saat dihentikan dengan TweenBase:Cancel() .

Mengembalikan Enum.PlaybackState dari tween ke fungsi terhubung untuk memberikan indikasi mengapa tween berakhir. Catat bahwa memanggil TweenBase:Pause() tidak mengecualikan acara Completed.

Parameter

playbackState: Enum.PlaybackState

ENSEMBLE.PLAYBACKSTATUS dari tween setelah selesai.


Contoh Kode

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.

Tween Completed
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

end



local function onCharacterAdded(character)

	local humanoid = character:WaitForChild("Humanoid")

	local initialSpeed = humanoid.WalkSpeed

	local tweenSpeed = slowCharacter(humanoid)

	tweenSpeed.Completed:Wait()

	humanoid.WalkSpeed = initialSpeed

end



local function onPlayerAdded(player)

	player.CharacterAdded:Connect(onCharacterAdded)

end



Players.PlayerAdded:Connect(onPlayerAdded)

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.

Verifying a Tween has Completed
local TweenService = game:GetService("TweenService")



local part = Instance.new("Part")

part.Position = Vector3.new(0, 50, 0)

part.Anchored = true

part.Parent = workspace



local goal = {}

goal.Position = Vector3.new(0, 0, 0)



local tweenInfo = TweenInfo.new(3)



local tween = TweenService:Create(part, tweenInfo, goal)



local function onTweenCompleted(playbackState)

	if playbackState == Enum.PlaybackState.Completed then

		local explosion = Instance.new("Explosion")

		explosion.Position = part.Position

		explosion.Parent = workspace

		part:Destroy()

		task.delay(2, function()

			if explosion then

				explosion:Destroy()

			end

		end)

	end

end



tween.Completed:Connect(onTweenCompleted)
