Sometimes regular mods aren’t enough. For that you can create a custom window.

You can create one by creating a class extending BaseWindow:

public class MyWindow : BaseWindow
{
    public MyWindow()
    {
        Name = "My Window";
        TitleIcon = Lucide.Hexagon;
    }

    public override Group ConstructUI()
    {
        return new Group(Name);
    }

    public override void RefreshUI()
    {

    }
}

Then you can instantiate it in your Plugin’s Awake method:

private static MyWindow myWindow;

private void Awake()
{
    myWindow = new MyWindow();
}

The window should now appear in game and you can start adding UI elements to the Window:

public class MyWindow : BaseWindow
{
    public static Ref<float> MyFloat = new();

    private static bool initialized;

    public MyWindow()
    {
        Name = "My Window";
        TitleIcon = Lucide.Hexagon;

        if(initialized)
        {
            return;
        }

        MyFloat.Changed += num =>
        {
            Player.Speed = num;
        }

        initialized = true;
    }

    public override Group ConstructUI()
    {
        return new Group(Name,
            new DragFloat("My Float").WithValue(MyFloat)
        );
    }

    public override void RefreshUI()
    {
        MyFloat.Value = Player.Speed;
    }
}
