Background
One of the great frontiers to migrate from Unity4 to Unity5 is no longer have code within the game using the old format to work with the interface for the player (UI). In the former Unity everything was done through OnGUI event and now I'm working heavily on migrating many many lines of code to the visual organization of objects within the hierarchy of the Unity.
Good part of the process of generation of the elements in the map screen of the game and the scenes that were derived from the choices made have already been migrated to Unity UI, the bright side is that I'm going to eliminate two scenes of compiling ... the downside is that I still have a lot of work to do.
