Yet Another Unity Tween Library

Tween.cs

No need for using, everything necessary is in global namespace. Just drop Tween.cs anywhere in your project.

yield return new Tween(gameObject)
    .Position.X.Add(10, Easing.BounceOut)
    .Scale.To(Vector2.one * 0.5f, Easing.BounceOut)
    .Duration(1)
    .Then
    .Color.To(Color.red)
    .Duration(0.5f)
    .StartCoroutine(this);

Tween class provides shortcuts for .Transform.Position, .Transform.Scale and .Transform.Rotation...

yield return new Tween(gameObject)
    // This
    .Position.To(Vector3.left)
    .Scale.X.From(0).Add(2)
    .Rotation.Z.From(0).To(90)
    .Duration(1)
    .Then
    // Equals to this
    .Transform.Position.To(Vector3.left)
    .Transform.Scale.X.From(0).Add(2)
    .Transform.Rotation.Z.From(0).To(90)
    .Duration(1)
    .StartCoroutine(this);

... and for color and alpha (works for Graphic, SpriteRenderer and CanvasGroup)

yield return new Tween(gameObject)
    .Color.To(Color.red)
    .Alpha.To(0)
    .Duration(1)
    .StartCoroutine(this);

There are also a couple of extensions for common components

yield return new Tween(gameObject)
    .Image().FillAmount.To(1)
    .Text().FontSize.From(20).To(24)
    .AudioSource().Volume.To(0)
    .Duration(5)
    .StartCoroutine(this);

All easings can be passed in To() and Add() methods

yield return new Tween(gameObject)
    .Position.Add(Vector3.one, Easing.SineOut)
    .Scale.X.From(0).Add(2, Easing.BounceInOut)
    .Rotation.Z.From(0).Add(90, Easing.ExpoOutIn)
    .Color.To(Color.red, Easing.QuartIn)
    .Duration(1)
    .StartCoroutine(this);

StartCoroutine(this) is necessary for things to work.

Todo

• Different playbacks (like loop, backwards, etc.)
• Attach different game object
• Wait(), Set(), Delay()

Maybe?

• Custom Unity editor
• Standard tweens (then we will need Tweens to be tweakable after constructing)
