我怎样才能等待3秒然后在C#中将bool设置为true？

Question

我的脚本/游戏/东西使游戏对象向右移动,当我点击舞蹈(我创建的按钮)时,它停止.然后当计数器(我可能不需要计数器,但我想要等待3秒)达到3(一旦你点击舞蹈计数器开始)我的游戏对象假设继续向右移动.

如果你能纠正那些很酷的代码.如果你能纠正它并向我解释我做错了什么就会更加棒极了.我刚开始在Unity上学习C#.

using System;
using UnityEngine;
using System.Collections;

public class HeroMouvement : MonoBehaviour
{
    public bool trigger = true;
    public int counter = 0;
    public bool timer = false;

    // Use this for initialization

    void Start()
    {
    }

    // Update is called once per frame

    void Update()
    {  //timer becomes true so i can inc the counter

        if (timer == true)
        {
            counter++;
        }

        if (counter >= 3)
        {
            MoveHero();//goes to the function moveHero
        }

        if (trigger == true)
            transform.Translate(Vector3.right * Time.deltaTime); //This moves the GameObject to the right
    }

    //The button you click to dance 
    void OnGUI()
    {
        if (GUI.Button(new Rect(10, 10, 50, 50), "Dance"))
        {
            trigger = false;
            timer = true;//now that the timer is set a true once you click it,The uptade should see that its true and start the counter then the counter once it reaches 3 it goes to the MoveHero function      
        }
    }

    void MoveHero()
    {  //Set the trigger at true so the gameobject can move to the right,the timer is at false and then the counter is reseted at 0.
        trigger = true;
        timer = false;
        counter = 0;
    }
}

您可以使用协同程序轻松完成:

void Update()
{
    if (trigger == true)
        transform.Translate(Vector3.right * Time.deltaTime); //This moves the GameObject to the right
}

void OnGUI()
    {
        if (GUI.Button(new Rect(10, 10, 50, 50), "Dance"))
        {  
           StartCoroutine(DoTheDance());
        }
    }


 public IEnumerator DoTheDance() {
    trigger = false;
    yield return new WaitForSeconds(3f); // waits 3 seconds
    trigger = true; // will make the update method pick up 
 }

有关Coroutines以及如何使用它们的更多信息,请参见http://docs.unity3d.com/Documentation/ScriptReference/index.Coroutines_26_Yield.html.在尝试进行一系列定时活动时,它们非常整洁.

我认为最简单的方法是使用Invoke:

Unity3D调用

if (timer == true) Invoke("MoveHero", 3);

Answer 3

首先让计数器成为一个浮动。然后更改counter++;为counter += Time.deltaTime. 每帧都会调用 Update()，因此第三帧上的计数器将为 3。Time.deltaTime 为您提供此帧与上一帧之间的时间。总结起来就像一个计时器。
