Unity计时器（全）

Unity计时器

 

 

游戏中有非常多的计时功能，比如:各种cd,以及需要延时调用的方法；

一般实现有一下几种方式：

1.手动计时

float persistTime = 10f
float startTime = Time.time;
if(Time.time - startTime > persistTime)
{Debug.Log("计时结束");
}float curTime = 0;
curTime += Time.deltaTime;
if(curTime > persistTime)
{Debug.Log("计时结束");
}

2：协程

private float persistTime = 10f;
IEnumerator DelayFunc()
{yield return persistTime;Debug.Log("计时结束");
}private void Start()
{StartCoroutine(DelayFunc());
}

3.Invoke回调

private void Start()
{Invoke("DelayFunc", persistTime);
}

计时器功能

计时是为了到特定的时间，执行某个功能或方法；

计时器（Timer）：设计了计时暂停，计时重置，计时开始方法，计时中方法，计时结束方法，固定间隔调用方法，计时器可设置复用或单次；

计时管理器（TimerMa）：负责倒计时，以及执行计时器方法；

代码：

using System;
using System.Collections.Generic;
using UnityEngine;
using Object = System.Object;public class Timer
{public delegate void IntervalAct(Object args);//总时间和当前持续时间private float curtime = 0;private float totalTime = 0;//激活public bool isActive;//计时结束是否销毁public bool isDestroy;//是否暂停public bool isPause;//间隔事件和间隔事件——Dotprivate float intervalTime = 0;private float curInterval = 0;private IntervalAct onInterval;private Object args;//进入事件public Action onEnter;private bool isOnEnter = false;//持续事件public Action onStay;//退出事件public Action onEnd;public Timer(float totalTime, bool isDestroy = true, bool isPause = false){curtime = 0;this.totalTime = totalTime;isActive = true;this.isDestroy = isDestroy;this.isPause = isPause;TimerMa.I.AddTimer(this);}public void Run(){//暂停计时if (isPause || !isActive)return;if (onEnter != null){if (!isOnEnter){isOnEnter = true;onEnter();}}//持续事件if (onStay != null)onStay();curtime += Time.deltaTime;//间隔事件if (onInterval != null){curInterval += Time.deltaTime;if (curInterval > intervalTime){onInterval(args);curInterval = 0;}}//计时结束if (curtime > totalTime){curtime = 0;isActive = false;if (onEnd != null){onEnd();}}   }//设置间隔事件public void SetInterval(float interval, IntervalAct intervalFunc, Object args = null){this.intervalTime = interval;onInterval = intervalFunc;curInterval = 0;this.args = args;}//重置计时器public void Reset(){curtime = 0;isActive = true;isPause = false;curInterval = 0;isOnEnter = false;}//获取剩余时间public float GetRemainTime(){return totalTime - curtime;}
}

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class TimerMa : MonoBehaviour
{#region 单例private static TimerMa instance;TimerMa() {}public static TimerMa I{get{if (instance == null)instance = new TimerMa();return instance;}}#endregionprivate List<Timer> timerList;private void Awake(){instance = this;timerList = new List<Timer>();}public void AddTimer(Timer t){timerList.Add(t);}void Update(){for (int i = 0; i < timerList.Count;){timerList[i].Run();//计时结束，且需要销毁if(!timerList[i].isActive && timerList[i].isDestroy)timerList.RemoveAt(i);else++i;}}
}

测试计时器

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Object = System.Object;public class Test : MonoBehaviour
{public Text mText1;public Text mText2;private Timer timer;private int count = 0;void Start(){timer = new Timer(5f,false);timer.SetInterval(1f, OnInterval);timer.onEnter = OnStart;timer.onEnd = OnExit;}void Update(){Debug.Log(count);mText1.text = timer.GetRemainTime().ToString("f2");if (Input.GetKeyDown(KeyCode.A)){if (!timer.isPause){timer.isPause = true;mText2.text = "暂停计时";}}if (Input.GetKeyDown(KeyCode.S)){if (timer.isPause){timer.isPause = false;mText2.text = "取消暂停计时";}}if (Input.GetKeyDown(KeyCode.D)){timer.Reset();mText2.text = "重置计时";}}private void OnStart(){mText2.text = "开始计时";}private void OnExit(){mText2.text = "结束计时";}private void OnInterval(Object value){count++;mText2.text = $"间隔事件调用{count}";}
}
