Lightweight tween library for Unity aimed at making tweening objects dead simple and completely flexible. The wiki contains some usage information and examples.Short answer: anything. You can tween any property on any object of type Vector2, Vector3 (including through a series of Vector3s), Vector4, int, float or Color. These make up what we call generic tweens. Generic tweens are slightly slower than specific tweens. We did some heavy-duty benchmarking and used some .NET trickery to make them pretty darn fast though. That being said, the library also offers what we call specific tweens. These are confined to a specific target object type and property and use direct access for the tween making them hyper fast. The available specific tweens are eulerAngles, localEulerAngles, material colors (_Color, _SpecColor, _Emission and _ReflectColor), position, localPosition (along with following a path) and scale. You can also always make your own specific Tweens using the fully extensible TweenProperty system.
