ios - 如何添加计时器？

Question

我有一个具有多点触摸功能的Unity脚本，它将检测触摸，查看触摸是否撞到了撞机(gameObject的一部分)，然后检查它是否是正确的撞机，并销毁它。这是工作代码:

using UnityEngine.UI;
using UnityEngine;
using System.Collections;

public class GameController : MonoBehaviour 

{

    void Update () // Updates every frame
    {
        if (Input.touchCount != 0) // Triggered by a touch
        {
            foreach (Touch touch in Input.touches) // Triggered as many times as there are touches.
            {
                RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(touch.position), Vector2.zero);
                if (hit && touch.phase == TouchPhase.Began && hit.collider.gameObject.tag ==("Fish")) // Triggered if touch hits something, when touch just begins, and if the object hit was tagged as a "Fish"
                {
                    hit.collider.gameObject.GetComponent<FishScript>().TappedOut(); // Fish script activated
                }
            }
        }
    }
}

这是工作代码。现在，我想在其中添加一个计时器，并希望它可以计时触摸。我想做到这一点，只要玩家可以点击，然后将手指移到鱼上，它就会计数，只要在1秒钟内将手指移到鱼上即可。这是我编写的脚本，需要帮助:

using UnityEngine.UI;
using UnityEngine;
using System.Collections;

public class GameController : MonoBehaviour 

{

    void Update () // Updates every frame
    {
        if (Input.touchCount != 0) // Triggered by a touch
        {
            foreach (Touch touch in Input.touches) // Triggered as many times as there are touches.
            {
                if (touch.phase == TouchPhase.Began)
                {
                    float touchTimer = Time.time;
                    int i = touch.fingerId;
                }
                RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(touch.position), Vector2.zero);
                if (hit && hit.collider.gameObject.tag ==("Fish")) // Triggered if touch hits something, when touch just begins, and if the object hit was tagged as a "Fish"
                {
                    hit.collider.gameObject.GetComponent<FishScript>().TappedOut(); // Fish script activated
                }
            }
        }
    }
}

到目前为止，这就是我所拥有的。我尝试使用return语句，但在Void Update()函数中不起作用。我尝试用while循环制作另一个函数，该循环要等到每一帧完成之后再经历另一个循环。那没有用。这个想法行得通吗？

这是Unity中的一个简单计时器。将CheckTimer()放在Update()方法上。

private double counter = 0.000d;
public double time = 2.000d; // How many seconds you want your timer to run

void CheckTimer()
{
    counter+= Time.deltaTime;
    if (counter >= time)
    {
        // Time has passed
        counter = 0.000d;
        // Do stuff here..
    }
}

对于您的情况，可以在满足条件时将bool设置为true，然后进行设置，以便 CheckTimer()仅在条件为true时运行。
