        bool kill = Main.tile[x, y]?.active() == false;//方块是否被挖掉

        //遍历范围内的方块, 即使没相连也会被一起挖掉
        for (int i = x - Size; i < x + Size; i++)

        }

初始化修补

internal class PatchInit : Mod
{
    private const string patchId = "tPlainModLoader.Mod.test1.gamePatch";//修补的id, 应该写啥都行
    private Harmony harmony = null;

    public override void AddPatch(IAddPatch addPatch)//添加修补
    {
        harmony = new Harmony(patchId);
        harmony.PatchAll();//修补全部
    }

    public override void Unload()
    {
        harmony?.UnpatchAll(patchId);//卸载修补
        harmony = null;
    }
}

UI窗口

internal class PickWindow : UIWindow//继承了模板UIWindow
{
    public PickWindow(string title, int width, int height) : base(title, width, height)
    {
        UIStackPanel sp = new UIStackPanel();//竖向排列子控件
        sp.Width.Set(0, 1);
        sp.Height.Set(0, 1);
        Child.Append(sp);//将sp添加到窗口. 要向窗口添加控件就用这个

        UIItemSwitch enable = new UIItemSwitch(null, "启用");
        enable.OnValUpdate += v => PPlayer.Enable = v;
        enable.SetVal(PPlayer.Enable);
        sp.Append(enable);

        UIItemTextBox size = new UIItemTextBox(text: "半径");
        size.OnTextChanged += v =>
        {
            if (ushort.TryParse(v, out ushort val)) PPlayer.Size = val;
        };
        size.SetText(PPlayer.Size.ToString());
        sp.Append(size);

        UIItemSwitch pickEffect = new UIItemSwitch(null, "挖掘效果");
        pickEffect.OnValUpdate += v => PPlayer.PickEffect = v;
        pickEffect.SetVal(PPlayer.PickEffect);
        sp.Append(pickEffect);
    }
}

添加UI

internal class ModifyInterfaceLayers : PatchMain
{
    private UIState state = null;
    private UserInterface ui = null;
    private PickWindow window = null;

    //和tModLoader中一样在这插入ui
    public override void SetupDrawInterfaceLayersPostfix(List<GameInterfaceLayer> gameInterfaceLayers)
    {
        //"Vanilla: Inventory"是物品栏图层的名称
        int index = gameInterfaceLayers.FindIndex(i => i.Name == "Vanilla: Inventory");
        if (index == -1) return;

        window = new PickWindow("简易连锁挖矿", 260, 160);
        state = new UIState();
        ui = new UserInterface();
        //state.Append(window);控件在这里添加就行了, 由于UIWindow在打开的时候会自动添加所以不需要这句
        //state.Append(ui1);
        //state.Append(ui2);
        //state.Append(ui...);

        //在物品栏前插入
        gameInterfaceLayers.Insert(index, new LegacyGameInterfaceLayer(
            "StaticTile.test1: Inventory Prefix(属于你的图层名称, 写啥都行)",
            () =>
            {
                ui.Draw(Main.spriteBatch, Main.gameTimeCache);//绘制ui
                return true;
            },
            InterfaceScaleType.UI));
    }

    public override void UpdateUIStatesPostfix(GameTime gameTime)
    {
        if (ui == null) return;

        if (Main.gameMenu)//在游戏外
        {
            ui.SetState(null);//禁用ui
            return;
        }

        ui.SetState(state);//启用ui
        ui.Update(gameTime);//更新ui

        //快捷键'P'开关窗口
        if (Main.keyState.IsKeyDown(Keys.P) && Main.oldKeyState.IsKeyUp(Keys.P))
        {
            if (window.IsOpen) window.Close();//从state删除
            else window.Open(state);//添加到state
        }
    }
}
