The C# UI makes it possible to quickly create a simple UI without using external tools such as Scaleform. Currently the C# UI is able to:

Introduction

The UI in C# runs basically on two classes. The first class is the UIElement-class, which inherits from SceneObject and adds support for a RectTransform. The RectTransform defines information about the location, orientation and size of each UIElement. The second class is the UIComponent-class, which defines the behavior of the UIElement. Each UIElement can have multiple UIComponents.

Every UI starts with a Canvas. The Canvas is responsible for drawing the UI to the screen or to a render texture and delegating events to its child UIElements. Every UIElement has to be a child of a Canvas. A scene can have multiple Canvas instances at the same time.
