帮助我用OnMouseButton()为手机改变我的"ClickCounter.cs"。我想显示我点击了多少次，但是我的var"count"在Update()中每帧递增。我的鼠标代码- "ClickCounter.cs"

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
public class ClickCounter : MonoBehaviour
{
    Text ScoreText; //var for my text
    void Start()
    {
        ScoreText = GameObject.Find("Score").GetComponent<Text>();
    }

    int count = 0;
    void OnMouseDown() //func count my click, but cant counting multitouch 
    {
       count++;
       ScoreText.text = "Score: " + count.ToString(); //text field with score (click count)
       GameObject.Find("Pride").GetComponent<Animator>().SetTrigger("Click"); //some animation
       Debug.Log(count);
    }
}

我的android代码

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
public class TouchCounter : MonoBehaviour
{
    Text scoreText;
    void Start()
    {
        scoreText = GameObject.Find("Score").GetComponent<Text>(); //same 
    }

    void Update ()
    {
            if (Input.touchCount > 0) Counter(); //touch check
    }
    int count = 0;
    void Counter() //
    {
            count++;
            scoreText.text = "Score: " + count.ToString();
            GameObject.Find("Pride").GetComponent<Animator>().SetTrigger("Click");
    }
}

多点触点计数

当一个手指或多个手指放在屏幕上时，if (Input.touchCount > 0)总是true。因为这是在Update函数中运行的，所以Counter()将根据你的帧率每秒被调用几十次。

您还必须检查TouchPhase.Ended或TouchPhase.Began。

if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended) Debug.Log("Tapped");

或

if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) Debug.Log("Tapped");

应该做。

即使这应该工作，还有另一个问题。如果有多个手指同时敲打，它就无法工作了。你必须在Input.touchCount上循环，使这个工作与多个手指。

另一件事是，一个点击应该有一个计时器。一个计时器，用于确定是否应将此视为轻击。例如，手指在屏幕上停留超过一秒钟不应该被称为点击。下面的解决方案解决了所有这些问题。timeOut变量可以用来设置玩家的手指在屏幕上停留多长时间才算点击。

默认情况下，任何超过0.5秒的动作都不是点击。

float[] fingerIdTimer = new float[5] { 0f, 0f, 0f, 0f, 0f }; //5 fingers max
bool[] fingerIdValid = new bool[5] { true, true, true, true, true }; //One determine invalid, must be rest in TouchPhase.Ended
const float timeOut = 0.5f; //Anything more than 0 and less than timeOut value is tap
void Update()
{
    //Loop over all finger touching the screen
    for (int i = 0; i < Input.touchCount; i++)
    {
        //Will only increment if finger is valid
        if (fingerIdValid[i])
        {
            fingerIdTimer[i] += Time.deltaTime;
        }
        //If we reach the time out value and finger is still valid reset the finger id
        if (fingerIdTimer[i] > timeOut && fingerIdValid[i])
        {
            fingerIdTimer[i] = 0f; //Reset Held Time
            fingerIdValid[i] = false; //Invalid
            OnTapFailed(i, fingerIdTimer[i]);
        }
        //After touch is released, Anything more than 0 and less than timerOut value is tap
        if (Input.GetTouch(i).phase == TouchPhase.Ended)
        {
            if (fingerIdTimer[i] > 0 && fingerIdTimer[i] < timeOut)
            {
                OnTapSuccess(i, fingerIdTimer[i]);
            }
            fingerIdTimer[i] = 0f; //Reset Held Time when released
            fingerIdValid[i] = true; //Reset Invalid when released
        }
    }
}
int count = 0;
//Tap was successful
void OnTapSuccess(int fingerId, float heldTime)
{
    count++; //Increment the tap count
    Debug.Log("Tapped Count: " + count + "'r'n"
        + "Finger ID: " + fingerId + "'r'n"
        + "Held Time: " + heldTime);
    //scoreText.text = "Score: " + count.ToString();
    //GameObject.Find("Pride").GetComponent<Animator>().SetTrigger("Click");
}
//Tap failed (Time out Occured)
void OnTapFailed(int fingerId, float heldTime)
{
    Debug.Log("Tap Failed: " + fingerId);
}

设置count = 0，但是在Update函数之外。所以在一次触摸之后，count总是为!0。
