Timer两种计时器

一、倒计时计时器（常用语UI倒计时显示）

这个计时器是一个继承自MonoBehavior的脚本，使用的时候直接使用静态方法创建即可
可以同时控制多个物体互相不影响

计时器代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public delegate void TimerCompleteEvent();public delegate void UpdateEvent(int t);public class Timer : MonoBehaviour {/// <summary>/// 完成委托/// </summary>TimerCompleteEvent del;/// <summary>/// 实时委托/// </summary>UpdateEvent updatedel;/// <summary>/// 总秒数/// </summary>private int second = 10;/// <summary>/// 上前的时间/// </summary>private int previous = 10;/// <summary>/// 开关/// </summary>public bool isopen = false;/// <summary>/// 计时使用/// </summary>private float totalTime = 0;/// <summary>/// 计时器/// </summary>private void Timers(){//累加每帧消耗时间totalTime += Time.deltaTime;if (second == 0){if (del != null){del();}StopTimer();}if (totalTime >= 1)//每过1秒执行一次{second--;totalTime = 0;if (updatedel != null) updatedel(second);}}/// <summary>/// 开启计时器/// </summary>public void StartTimer(int total, TimerCompleteEvent timedel,UpdateEvent update){totalTime = 0;second = total;previous = total;isopen = true;del = timedel;updatedel = update;}/// <summary>/// 创建计时器/// </summary>/// <param name="name"></param>/// <returns></returns>public static Timer CreateTimer(string name){GameObject m_currTimer = new GameObject(name);Timer time = m_currTimer.AddComponent<Timer>();return time;}/// <summary>/// 暂停计时器/// </summary>public void PauseTimer(){isopen = false;}/// <summary>/// 继续计时器/// </summary>public void Continue(){isopen = true;}/// <summary>/// 重新计时/// </summary>public void ReStartTimer(){second = previous;totalTime = 0;}/// <summary>/// 停止计时/// </summary>public void StopTimer(){if (this == null) return;isopen = false;totalTime = 0;del = null;updatedel = null;Destroy(gameObject);}private void Update(){if (isopen){Timers();}}
}

用法如下：

using UnityEngine;public class TimerCtrl : MonoBehaviour {Timer tim;// Use this for initializationvoid Start () {tim = Timer.CreateTimer("TimerCtrl1");tim.StartTimer(10,()=> {Debug.LogError("TimerCtrl1完成");},(time)=> {Debug.LogError("TimerCtrl1:"+time);});}// Update is called once per framevoid Update () {if (Input.GetKeyDown(KeyCode.Q)){tim.PauseTimer();}if (Input.GetKeyDown(KeyCode.W)){tim.ReStartTimer();}if (Input.GetKeyDown(KeyCode.E)){tim.StopTimer();}}
}

二、技能CD计时器

代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public delegate void FinishEventHandler();public delegate void UpdateEventHandler(float time);public class MyTimer : MonoBehaviour {/// <summary>/// 打印开关/// </summary>public bool isLog = true;/// <summary>/// 实时调用委托/// </summary>UpdateEventHandler updateEvent;/// <summary>/// 实时调用委托/// </summary>FinishEventHandler finishEvent;/// <summary>/// 计时时间/// </summary>float timeTarget;/// <summary>/// 开始计时时间/// </summary>float timeStart;/// <summary>/// 现在时间/// </summary>float timeNow;/// <summary>/// 计时偏差/// </summary>float offsetTime;/// <summary>/// 是否开始计时/// </summary>bool isTimer;/// <summary>/// 计时结束后是否销毁/// </summary>bool isDestory = true;/// <summary>/// 计时是否结束/// </summary>bool isEnd;/// <summary>/// 是否忽略时间速率/// </summary>bool isIgnoreTimeScale = true;/// <summary>/// 是否重复/// </summary>bool isRepeate;/// <summary>/// 真实时间/// </summary>float _Time{get{/// realtimeSinceStartup 是开始运行的时间切换应用不对其影响（真是时间）/// time 是开始运行的时间切换应用不对其影响（实际时间）return isIgnoreTimeScale ? Time.realtimeSinceStartup : Time.time;}}/// <summary>/// 当前所用时间/// </summary>float now;private void Update(){if (!isTimer) return;timeNow = _Time - offsetTime;now = timeNow - timeStart;if (updateEvent != null) updateEvent(Mathf.Clamp01(now/timeTarget));//与目标值的比例当为1的时候完成if (now > timeTarget) //超过目标值{if (finishEvent != null) finishEvent();if (!isRepeate) Destory();else ReStartTimer();}}/// <summary>/// 经过的时间/// </summary>/// <returns></returns>public float GetLeftTime(){return Mathf.Clamp(timeTarget - now,0,timeTarget);}private void OnApplicationPause(bool pause){if (pause){PauseTimer();}else{ConnitueTimer();}}/// <summary>/// 计时结束/// </summary>private void Destory(){isTimer = false;isEnd = true;if (isDestory) Destroy(gameObject);}/// <summary>/// 暂停时间/// </summary>float _pauseTime;/// <summary>/// 暂停计时器/// </summary>public void PauseTimer(){if (isEnd){if (isLog) Debug.LogError("计时已经结束");}else{if (isTimer){isTimer = false;_pauseTime = _Time;}}}/// <summary>/// 重新计时/// </summary>public void ConnitueTimer(){if (isEnd){if (isLog) Debug.LogError("计时已经结束!请重新开始!");}else{if (!isTimer){offsetTime += (_Time - _pauseTime);isTimer = true;}}}/// <summary>/// 重新计时/// </summary>public void ReStartTimer(){if (!isTimer) isTimer = true;if (isEnd) isEnd = false;timeStart = _Time;offsetTime = 0;_pauseTime = 0;}/// <summary>/// 停止计时器/// </summary>public void StopTimer(){Destory();}/// <summary>/// 开始计时/// </summary>public void StartTiming(float _time,FinishEventHandler finishdel,UpdateEventHandler updatedel = null, bool _isIgnoreTimeScale = true, bool _isRepeate = false,bool _isDestory = true){//设置目标时长timeTarget = _time;//设置委托if (finishdel != null) finishEvent = finishdel;if (updatedel != null) updateEvent = updatedel;isDestory = _isDestory;isIgnoreTimeScale = _isIgnoreTimeScale;isRepeate = _isRepeate;timeStart = _Time;offsetTime = 0;isEnd = false;isTimer = true;}/// <summary>/// 创建计时器：名字/// </summary>/// <returns></returns>public static MyTimer CreateTimer(string objName = "Timer"){GameObject go = new GameObject(objName);MyTimer timer = go.AddComponent<MyTimer>();return timer;}
}

使用方法如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class MyTimer1 : MonoBehaviour {MyTimer myTimer;// Use this for initializationvoid Start () {myTimer = MyTimer.CreateTimer();myTimer.StartTiming(5,()=>{Debug.LogError("完成回调=====>");},(t)=> {Debug.LogError("实时刷新Timer1=="+t);});}// Update is called once per framevoid Update () {if (Input.GetKeyDown(KeyCode.Q)){myTimer.PauseTimer();}if (Input.GetKeyDown(KeyCode.W)){myTimer.ConnitueTimer();}if (Input.GetKeyDown(KeyCode.E)){myTimer.ReStartTimer();}if (Input.GetKeyDown(KeyCode.R)){myTimer.StopTimer();}}
}
