uGUI: Under the Hood

Unity Engine
1

Has anyone seen any blogs/articles/tutorials/posts/anything about how uGUI works?

I’ve been looking through the source code on BitBucket, but I’m struggling to get my head around it. Some kind of guide or primer would be really helpful.

I’m especially interested in how Recasting is implemented for GUI objects (if indeed it is used at all).

Thanks

THe events dont use raycasting for UI objects. It uses a point inside a rectangle algorithm to determine if the mouse is inside one of the UI objects.
