As we start to look deep into the crystal ball, we gaze upon our first sights of the new Unity UI system. In a breath of fresh air, Unity UI has appeared to aid the weary UI developer, who just wants their UI their own way.
We start with the beginnings of Unity UI and the foundations that it builds upon, most notably the Sprite 2D system that was introduced with Unity 4.3. However, Unity UI takes these simple beginnings and takes a bold leap forward. Almost every underlying part of the new sprite system has been improved and stretched to build something that is sensible and just works. In those areas, where it does not stretch enough, there is a base framework for extensibility; don't like it the way Unity has put it together, then do it your own way.
The following is the list of topics that will be covered in this chapter:
The new Rect Transform
The Unity UI canvas
Layout and grouping systems
Unity Events and the new EventSystem
