如何在一定时间后将变量设置为零

问题描述：

因此，我正在尝试将乒乓游戏作为Unity的学习活动。我正在努力为乒乓球制造一个复位系统，如果它被卡在永久弹跳下来的话。如何在一定时间后将变量设置为零

我设置的底壁对撞机触发和顶壁撞机触发1。例如递增一个接触变量，如果球击中了游戏的顶壁HitsTop变量将通过1

递增

对于底壁同样如此。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。

我想添加一些代码，在一段时间后，比如说5秒，将重置HitsTop和HitsBottom变量。

这是可能的C＃？

我的代码，例如：

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; 
     } 
    } 
}

是有可能在C＃ - 请张贴一些代码。 –

答

使用Time.deltaTime递减的变量。

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，当你增加HitsTop或HitsBottom，计时器重置为5

这段代码对我来说非常合适。非常感谢！ :) –

很高兴成为服务 –
