// 模态确认框

{
    // 回调函数类型定义
    public delegate void CfmDlgCallBackFunc();

    // 点击确认按钮后的回调函数
    private CfmDlgCallBackFunc _confirmFunc;

    // 点击取消按钮后的回调函数
    private CfmDlgCallBackFunc _cancelFunc;

    // 显示提示
    public static void ShowTips(Node parent, string tips, CfmDlgCallBackFunc confirmFunc, CfmDlgCallBackFunc cancelFunc = null)
    {
        ConfirmationDialogEx dlg = new ConfirmationDialogEx();

    // 设置提示

        parent.AddChild(this);
        DialogText = tips;
        PopupExclusive = true;
        WindowTitle = "提示";
        GetOk().Text = "确定";
        GetCancel().Text = "取消";
        PopupCentered();
        Connect("popup_hide", this, nameof(OnClose));
        GetOk().Connect("pressed", this, nameof(OnOk));

    // 点击确认按钮
    private void OnOk()
    {

    // 点击取消（关闭）按钮
    private void OnCancel()
    {
        if (null != _cancelFunc)
            _cancelFunc();
    }

    // 关闭对话框
    private void OnClose()
    {
        Node parent = GetParent();
        if (null != parent)
            parent.RemoveChild(this);

        QueueFree();
    }
}

使用：

using Godot;

public class Main : Control
{
    public override void _Ready()
    {
        GetNode("Button").Connect("pressed", this, "OnClick");
    }

    void OnClick()
    {
        ConfirmationDialogEx.ShowTips(this, "你好吗?",
        () => {
            GD.Print("我很好！");
        },
        () => {
            GD.Print("不太好。");
        });
    }
}
