Métodos

  • Cancel():()

    Detiene la reproducción y restablece las variables preadolescentes.Si luego llamas a TweenBase:Play(), las propiedades del preadolescente reanudan la interpolación hacia su destino, pero toman toda la longitud de la animación para hacerlo.

  • Pause():()

    Detiene la reproducción del intermediación/interpolación de movimiento.No restablece sus variables de progreso, lo que significa que si llamas a TweenBase:Play(), el preadolescente reanuda la reproducción desde el momento en que se pausó.

  • Play():()

    Comienza la reproducción de un intermediación/interpolación de movimiento.Tenga en cuenta que si la reproducción ya ha comenzado, llamar Play() no tiene efecto a menos que el preadolescente haya terminado o se haya detenido (ya sea por TweenBase:Cancel() o TweenBase:Pause() ).

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)

Cancel

()

Detiene la reproducción de un Tween y restablece las variables de transición.

Solo restablece las variables de preadolescente, no las propiedades que cambia el intermediación/interpolación de movimiento.Si cancelas un preadolescente a mitad de su animaciones, las propiedades no se restablecen a sus valores originales.Difiere de TweenBase:Pause() en que una vez reanudada, toma la duración completa del preadolescente para completar la animaciones.

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

()

Detiene la reproducción del intermediación/interpolación de movimiento.No restablece sus variables de progreso, lo que significa que si llamas a TweenBase:Play(), el preadolescente reanuda la reproducción desde el momento en que se pausó.

Si quieres restablecer las variables de progreso del intermediación/interpolación de movimiento, usa TweenBase:Cancel().

Solo puedes pausar a los adolescentes que están en el PlaybackState de Enum. PlaybackState.Playing ; los adolescentes en otros estados no se pausarán.Si un preadolescente está en una diferente PlaybackState tal como Enum. PlaybackState.Delayed (como resultado de que su TweenInfo.DelayTime sea mayor que 0), intentar pausar al preadolescente fallará y el preadolescente se reproducirá después de su tiempo de retraso especificado.

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

()

Comienza la reproducción de un intermediación/interpolación de movimiento.Tenga en cuenta que si la reproducción ya ha comenzado, llamar Play() no tiene efecto a menos que el preadolescente haya terminado o se haya detenido (ya sea por TweenBase:Cancel() o TweenBase:Pause() ).

Múltiples adolescentes pueden jugarse en el mismo objeto al mismo tiempo, pero no deben animar la misma propiedad.Si dos adolescentes intentan modificar la misma propiedad, el tween inicial se cancela y se reemplaza por el tween más reciente (ver ejemplos).

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

Completed

Se enciende cuando el perfil termina de jugar o cuando se detiene con TweenBase:Cancel() .

Pasa el Enum.PlaybackState de la preadolescente a cualquier función conectada para dar una indicación de por qué terminó la preadolescente.Tenga en cuenta que llamar TweenBase:Pause() no activa el evento Completed.

Parámetros

playbackState: Enum.PlaybackState

El Enum.PlaybackState de la preadolescente al terminar.

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

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)
