TweenService 用于创建Tweens ，它们可以使用或渐变属性。Tweens 可以用于任何具有兼容属性类型的对象，包括：
TweenService:Create() , 主要的建造功能，需要 TweenInfo 对�ween 的描述，生成 Tween 对象，可以用于播放�ween。
注意，Tweens 可以同时为多个属性 interpolate ，但它们不能相互 interpolate 。如果两个 tween 尝试修改相同的属性，初始 tween 将被取消并由最新的 tween 覆盖。
代码示例
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 an example of how a looped tween can be created. A part is instanced in the Workspace and a Tween is created using TweenService:Create() that is set to animate its position along the Y axis.
The looped effect is achieved by modifying the TweenInfo used in TweenService:Create(). Specifically, when RepeatCount is set to less than 0, the tween will play indefinitely. Also, setting Reverses to true will cause the tween to play in reverse once it has reached its destination. In combination this creates a looped effect.
The correct way to make a tween play indefinitely is to set RepeatCount to -1. You should avoid using large numbers or math.huge() as a substitute as this is unstable and may stop working at any point.
local TweenService = game:GetService("TweenService")
local part = Instance.new("Part")
part.Position = Vector3.new(0, 10, 0)
part.Anchored = true
part.Parent = workspace
local tweenInfo = TweenInfo.new(
2, -- Time
Enum.EasingStyle.Linear, -- EasingStyle
Enum.EasingDirection.Out, -- EasingDirection
-1, -- RepeatCount (when less than zero the tween will loop indefinitely)
true, -- Reverses (tween will reverse once reaching its goal)
0 -- DelayTime
)
local tween = TweenService:Create(part, tweenInfo, { Position = Vector3.new(0, 30, 0) })
tween:Play()
task.wait(10)
tween:Cancel() -- cancel the animation after 10 secondsThis 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")
tween:Play()概要
方法
- GetValue(alpha : number,easingStyle : Enum.EasingStyle,easingDirection : Enum.EasingDirection):number
计算一个新的 alpha ，其中 Enum.EasingStyle 和 Enum.EasingDirection .
- SmoothDamp(current : Variant,target : Variant,velocity : Variant,smoothTime : number,maxSpeed : number?,dt : number?):Tuple
属性
方法
Create
Create 创建器从三个参数中创建一个新的 Tween：对象来补间动画，TweenInfo 特定义，以及包含拐变和值的表。
PropertyTable 参数需要为字典，其钥匙是属性的字符串名（例如 Position 、 Transparency 或 1> Color1>），值是 twee补间动画 的终点。
使用此函数创建的 Class.Tween 对对象使用作为 实例nst 参数独一无二。要将同一的渐变应用到另一个对象，请使用新对象再次调用此函数。
参数
Class.Instance 的属性要求渐变。
用于�weening 的属性和其目标值的字典。
