  • Refresh and reset the debug UI based on runtime changes.
  • Provides a global instance for easy access from anywhere in the codebase.
Examples
{
    /// Create a list to store the new DebugUI widgets
    /// by creating different DebugUI.Values that display a label with a value.
    var list = new System.Collections.Generic.List<DebugUI.Widget>
    {
        new DebugUI.Value { displayName = "Lighting Intensity", getter = () => 1.0f, setter = value => Debug.Log($"Lighting Intensity set to {value}") },
        new DebugUI.Value { displayName = "Light Color", getter = () => Color.white, setter = value => Debug.Log($"Light Color set to {value}") }
    };
    var items = list.ToArray();

    /// Obtain the panel from the DebugManager instance, and add the Widgets that we want to display there.
    var panel = DebugManager.instance.GetPanel("Lighting", true);
    panel.children.AddRange(items);
