UI Widgets is a collection of useful base ui scripts. Some of my assets include this package and extend from the base classes. You can download it using the Module Manager.
UIWidget is responsible for the management of widgets as well as animating them. Your custom widgets should extend from this class or from child classes. This way you can always track existing widgets by name in your game.
You can add a callback to control other elements of your game when dealing with a widget. Enable/Disable game objects, call a custom method if this widget is shown or closed.
