计时器功能

http://blog.csdn.net/fucun1984686003/article/details/46919775

 

计时器主要实现功能：

在规定的时间内倒计时，其中可以暂停，可以继续，可以设置是否受时间速率的影响等；

倒计时过程中可以时刻返回倒计时的状态；

可以获取倒计时剩余时间，倒计时结束的回调。

using UnityEngine;
using System.Collections;
using System;

public delegate void CompleteEvent();
public delegate void UpdateEvent(float t);

public class Timer : MonoBehaviour
{
bool isLog = true;

UpdateEvent updateEvent ;

CompleteEvent onCompleted ;

float timeTarget; // 计时时间/

float timeStart; // 开始计时时间/

float timeNow; // 现在时间/

float offsetTime; // 计时偏差/

bool isTimer; // 是否开始计时/

bool isDestory = true; // 计时结束后是否销毁/

bool isEnd; // 计时是否结束/

bool isIgnoreTimeScale = true; // 是否忽略时间速率

bool isRepeate;

float Time_
{
get { return isIgnoreTimeScale ? Time.realtimeSinceStartup : Time.time; }
}
float now;
// Update is called once per frame
void Update()
{
if (isTimer)
{
timeNow = Time_ - offsetTime;
now = timeNow - timeStart;
if (updateEvent != null)
updateEvent(Mathf.Clamp01(now / timeTarget));
if (now > timeTarget)
{
if (onCompleted != null)
onCompleted();
if (!isRepeate)
destory();
else
reStartTimer();
}
}
}
public float GetLeftTime()
{
return Mathf.Clamp(timeTarget - now, 0, timeTarget);
}
void OnApplicationPause(bool isPause_)
{
if (isPause_)
{
pauseTimer();
}
else
{
connitueTimer();
}
}

/// <summary>
/// 计时结束
/// </summary>
public void destory()
{
isTimer = false;
isEnd = true;
if (isDestory)
Destroy(gameObject);
}
float _pauseTime;
/// <summary>
/// 暂停计时
/// </summary>
public void pauseTimer()
{
if (isEnd)
{
if (isLog) Debug.LogWarning("计时已经结束！");
}
else
{
if(isTimer)
{
isTimer = false;
_pauseTime= Time_;
}
}
}
/// <summary>
/// 继续计时
/// </summary>
public void connitueTimer()
{
if (isEnd)
{
if (isLog) Debug.LogWarning("计时已经结束！请从新计时！");
}
else
{
if (!isTimer)
{
offsetTime += (Time_ - _pauseTime);
isTimer = true;
}
}
}
public void reStartTimer()
{
timeStart = Time_;
offsetTime = 0;
}

public void changeTargetTime(float time_)
{
timeTarget += time_;
}
/// <summary>
/// 开始计时 :
/// </summary>
public void startTiming(float time_, CompleteEvent onCompleted_, UpdateEvent update = null, bool isIgnoreTimeScale_ = true, bool isRepeate_ = false, bool isDestory_ = true)
{
timeTarget = time_;
if (onCompleted_ != null)
onCompleted = onCompleted_;
if (update != null)
updateEvent = update;
isDestory = isDestory_;
isIgnoreTimeScale = isIgnoreTimeScale_;
isRepeate = isRepeate_;

timeStart = Time_;
offsetTime = 0;
isEnd = false;
isTimer = true;

}
/// <summary>
/// 创建计时器:名字
/// </summary>
public static Timer createTimer(string gobjName = "Timer")
{
GameObject g = new GameObject(gobjName);
Timer timer = g.AddComponent<Timer>();
return timer;
}

}

 

 

以上是计时器功能的实现；怎么用这个计时器呢？

 

我们可以在需要计时器的脚本中这样去创建一个计时器：

 

实现代码：

 

using UnityEngine;
using System.Collections;

public class Test : MonoBehaviour
{

// Use this for initialization
void Start ()
{
// 创建计时器
Timer timer = Timer.createTimer ("Timer");
//开始计时
timer.startTiming (1, OnComplete, OnProcess);
}

// Update is called once per frame
void Update ()
{

}
// 计时结束的回调
void OnComplete ()
{
Debug.Log ("complete !");
}
// 计时器的进程
void OnProcess (float p)
{
Debug.Log ("on process " + p);
}
}
