The Zoetropic Animation system is a 2D animation system targeted for developers that do not have 2D animation software, do not have Unity Pro, or do not know how to or are not able to do 2D animations in any case. What this system does is take individual images and iterates through them as if they were frames of an animation. Essentially what it does is uses an array to hold the images used, then iterates through them in the order you wish and the speed that you wish.
The animation types that I've included are very similar to the types of 3D animations in Unity. I have code examples written for Loop, PlayOnce, Clamp, PingPong, and an example of Input Based animation. Included is a PDF showing the code snippet of each of the examples and I describe them too.
