Detailed Description

Base class for all UI objects.

UIObject represents a user interface element in the scene. It inherits from GameObject and adds properties specific to UI elements, such as width, height, pivot, and anchor points.

Note

UIObjects are intended to be used within a UI system and may have specific rendering and update logic.

This should be overridden by derived classes to implement specific rendering logic.

update()

inlinevirtual

Update the UI object.

This should be overridden by derived classes to implement specific update logic. Such as handling animations or state changes (e.g pressed, hovered, etc.).

Parameters

dt	Delta time since the last update.

Reimplemented in UIButton, UIInput, UIFPS, UIImage, and UIText.
