Question

我有一个带有多点触控功能的Unity脚本，可以检测触摸，看看触摸是否碰到了对手（游戏对象的一部分），然后检查它是否是正确的对撞机，并将其摧毁。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。现在我想在那里添加一个计时器，我希望它有时间触摸。我想这样做，如果玩家可以点击，并将他们的手指放在鱼上并且它会计数，只要在1秒钟内将手指移过鱼。这是我写的脚本，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，这就是我所拥有的一切。我尝试使用return语句，这在Void Update（）函数中不起作用。我尝试使用while循环创建另一个函数，该循环将等到每个帧完成后再通过另一个循环。那没用。这个想法会起作用吗？

Answer 1

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

CheckTimer()

在您的情况下，您可以在满足条件时将bool设置为true，然后使其socket.on('connect', function () { port.postMessage('connect'); }); socket.on('disconnect', function () { port.postMessage('disconnect'); });仅在条件为真时运行。

要解决此问题，请通过在顶部实例化并按以下步骤操作，使计时器成为全局变量

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

public class GameController : MonoBehaviour 

{
public float timer;
public float duration;

void Start(){
duration = 1; //you can set this in code or in your hierarchy in Unity 
}
    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)
                {
                    timer = Time.time + duration;
                }
if(Time.time < timer){
                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
                }
            }
}
        }
    }
}

我没有其余的代码来确保这可行，但其背后的逻辑确实如此。您希望将计时器设置为当前时间加上给定的持续时间。如果当前时间小于你在玩家做某事时设定的计时器，那么你知道他们在到达计时器之前就做了他们的动作。这有意义吗？

我知道我并不想通过说谢谢来占据评论空间，但感谢Jonnus。现在唯一让我感到困惑的是我怎么没有早点想到这一点。无论如何，这里是任何需要多点触控脚本帮助的人的代码。

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

    Private float timer;      //  Control variable
    Public float duration;    //  How long you want your touch to be valid

Void Start ()
{
    duration = 1;             // Also adjustable in the interface
}

Void Update ()
{
    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)
            {
                timer = Time.time + duration;
            }
            RaycastHit2D objectPlayerTouched = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(touch.position), Vector2.zero);
            // var objectPlayerTouched is the 2DCollider for whatever the player tapped on.
            if (objectPlayerTouched != null && Time.time < timer) // Triggered if player taps an object and time is still valid
            {
                objectPlayerTouched(destroy); // This means whatever object the player tapped is now destroyed
            }
        }
    }
}

再一次，非常感谢Jonnus。我认为这会复杂得多。另外，不要做我做的事情，忘记在界面中设置持续时间，最后花10分钟寻找问题......相信我这很烦人。
