如何在C#中检查玩家低于y坐标的时间

using System;

public class PlayerChecker
{
    private float thresholdY = 0; // 指定的y坐标阈值
    private DateTime lastCheckTime; // 上次检查的时间

    public void CheckPlayerYPosition(float playerY)
    {
        if (playerY < thresholdY)
        {
            DateTime currentTime = DateTime.Now;
            if (lastCheckTime == DateTime.MinValue)
            {
                lastCheckTime = currentTime;
            }
            else
            {
                TimeSpan timeSinceLastCheck = currentTime - lastCheckTime;
                Console.WriteLine("玩家低于y坐标的时间: " + timeSinceLastCheck.TotalSeconds + "秒");
                lastCheckTime = currentTime;
            }
        }
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        PlayerChecker playerChecker = new PlayerChecker();
        // 模拟玩家坐标变化
        playerChecker.CheckPlayerYPosition(10); // 假设玩家初始y坐标为10
        playerChecker.CheckPlayerYPosition(5); // 假设玩家低于y坐标
        playerChecker.CheckPlayerYPosition(3); // 假设玩家低于y坐标
        playerChecker.CheckPlayerYPosition(8); // 假设玩家回到y坐标以上
        playerChecker.CheckPlayerYPosition(2); // 假设玩家低于y坐标
    }
}
