因此，我正在尝试将乒乓球游戏作为 Unity 的学习活动。我正在为乒乓球制作一个重置系统，如果它被卡在永远上下弹跳。

我设置了一个底墙对撞机触发器和一个顶墙对撞机触发器，以将接触变量增加 1。例如，如果球击中游戏的顶墙，则该HitsTop变量将增加 1。

对于底墙也是如此。我的问题是，当球击中底壁和顶壁十次时，它会重置球的位置。

我想添加将在一段时间后重置HitsTop和变量的代码，比如 5 秒。HitsBottom

这在 C# 中可能吗？

我的代码是这样的：

using UnityEngine;
using System.Collections;

public class GameManager : MonoBehaviour {

    public static int PlayerScore1 = 0;
    public static int PlayerScore2 = 0;
    public static int HitsTop = 0;
    public static int HitsBottom = 0;

    public GUISkin layout;

    Transform theBall;

    // Use this for initialization
    void Start () {
        theBall = GameObject.FindGameObjectWithTag("Ball").transform;
    }

    public static void Score (string wallID) {
        if (wallID == "rightWall")
        {
            PlayerScore1++;
        } else if (wallID == "leftWall") {
            PlayerScore2++;
        }

        if (wallID == "topWallTrigger")
        {
            HitsTop++;
        } else if (wallID == "bottomWallTrigger") {
            HitsBottom++;
        }
    }

    void OnGUI () {
        GUI.skin = layout;
        GUI.Label(new Rect(Screen.width / 2 - 150 - 12, 20, 100, 100), "" + PlayerScore1 + HitsTop);
        GUI.Label(new Rect(Screen.width / 2 + 150 + 12, 20, 100, 100), "" + PlayerScore2 + HitsBottom);

        if (GUI.Button(new Rect(Screen.width / 2 - 60, 35, 120, 53), "RESTART"))
        {
            PlayerScore1 = 0;
            PlayerScore2 = 0;
            HitsTop = 0;
            HitsBottom = 0;
            theBall.gameObject.SendMessage("RestartGame", 0.5f, SendMessageOptions.RequireReceiver);
        }

        if (PlayerScore1 == 10)
        {
            GUI.Label(new Rect(Screen.width / 2 - 150, 200, 2000, 1000), "PLAYER ONE WINS");
            theBall.gameObject.SendMessage("ResetBall", null, SendMessageOptions.RequireReceiver);
        } else if (PlayerScore2 == 10)
        {
            GUI.Label(new Rect(Screen.width / 2 - 150, 200, 2000, 1000), "PLAYER TWO WINS");
            theBall.gameObject.SendMessage("ResetBall", null, SendMessageOptions.RequireReceiver);
        }
        if (HitsTop == 10) {
            theBall.gameObject.SendMessage("RestartGame", 1.0f, SendMessageOptions.RequireReceiver);
            HitsTop = 0;
        } else if (HitsBottom == 10) {
            theBall.gameObject.SendMessage("RestartGame", 1.0f, SendMessageOptions.RequireReceiver);
            HitsBottom = 0;
        }
    }
}

用于Time.deltaTime递减变量。

float timer = 5;    

void Update()
{
  //This will decrement the timer's value by the time. Once this hits zero, the timer is reset to its original value.
  timer -= Time.deltaTime;
  if(timer <= 0)
  {
   //Call reset game function
    timer = 5;
  }
}

此外，当您增加HitsTop或时HitsBottom，将计时器重置为 5。
