MonoGame UI Slider

A slider lets the user pick a float value within a [MinValue, MaxValue] range by dragging a thumb along a track. Supports horizontal and vertical orientation, optional step snapping, keyboard navigation, and gamepad control.

Assumed Contract

Extends UIElement from monogame-ui-core. Receives pointer events from monogame-ui-interaction (OnPointerDown, OnPointerUp, pointer position). Participates in focus via monogame-ui-focus for keyboard/gamepad increment.

Constructor

var slider = new Slider(pixel);          // pixel = 1×1 white Texture2D
slider.MinValue = 0f;
slider.MaxValue = 100f;
slider.Step     = 1f;                    // 0 = continuous float
slider.Orientation = Orientation.Horizontal;
