The new GUI system is already released but there is no documentation about it, only few tutorials that don’t let me dive deep in making really functional GUI. Is the API can be found somewhere else or am I missing something?
Note the documentation is not exactly what I’d call brilliant yet. There are a few things missing that mean its not up to Unity’s normal standard. But I’d imagine that will be corrected in time.
In the mean time you can watch my UI tutorials on YouTube
There is scripting API documentation present for the new UI elements.
In scripting API Under UnityEngine → UnityEngine.UI contains the scripting information for the new UI.
Find image below for more information:
Or you can even click the ‘Help’ button shown for any component in the Unity Editor to go to the respective scripting API page of that component.
