Summary
The UI Toolkit is still in development, but Unity is actively working on it as a system to replace the current uGUI system (that the rest of this book has focused on up to this point). It uses the concepts of web development to develop UI and can provide a cleaner, more performant UI than uGUI. However, since it is still in development, it doesn’t do everything uGUI does … yet. While you might not be able to fully transition over to the UI Toolkit system for your UI needs, it is helpful to have an idea of how it works, since one day, it will be your only option.
To help introduce the concepts of the UI Toolkit to you, we discussed the general concepts of the system as well as how to use it to make UI in the Editor and Runtime UI.
In the next chapter, we will discuss yet another UI system used within Unity: IMGUI.
