TweenService
TweenService is used to create Tweens which interpolate, or tween, the properties of instances. Tweens can be used on any object with compatible property types, including:
TweenService:Create(), the primary constructor function, takes TweenInfo specifications about the tween and generates the Tween object which can then be used to play the tween.
Note that Tweens can interpolate multiple properties at the same time, but they must not be interpolating 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.

Methods
Creates a new Tween given the object whose properties are to be tweened, a TweenInfo, and a dictionary of goal property values.
- GetValue(alpha : number,easingStyle : Enum.EasingStyle,easingDirection : Enum.EasingDirection):number
Calculates a new alpha given an Enum.EasingStyle and Enum.EasingDirection.
- SmoothDamp(current : Variant,target : Variant,velocity : Variant,smoothTime : number,maxSpeed : number?,dt : number?):Tuple
Properties
Methods
Create
The Create() constructor creates a new Tween from three arguments: the object to tween, the TweenInfo specifications, and a table containing the properties to tween and values to tween to.
The propertyTable parameter needs to be a dictionary where the keys are the string names of the property (for example Position, Transparency, or Color), and the values are the property targets at the end of the tween.
The Tween created using this function is unique to the object given as the instance parameter. To apply the same tween to another object, call this function again with the new object.
Parameters
A dictionary of properties, and their target values, to be tweened.

Returns a new alpha value for interpolating using the given alpha value, Enum.EasingStyle, and Enum.EasingDirection. The provided alpha value will be clamped between 0 and 1.
Parameters
An interpolation value between 0 and 1.
The easing style to use.
The easing direction to use.
Returns
A new alpha value generated from the given easing style and direction.
