Unity怎么暂停协程Unity协程管理方案

协程是游戏开发中非常常用的方法，类似一个子线程单独出来处理一些问题，性能开销较小。当然我们更多时候用的是他的延时执行功能

使用多了，难免有这样那样的需求。比如：暂停。比如：管理大量协程等
协程要在Mono类执行，销毁物体会停止协程，咋办

下面提供协程的一个管理器方案。

核心类有3个：

使用的时候只需要使用CoroutineMgr
CoroutineItem

using System.Collections;using UnityEngine;public class CoroutineItem : MonoBehaviour{ public enum CoroutineState{       WAITTING,       RUNNING,       PASUED,       STOP } public CoroutineState State{get;set;} public IEnumerator Body(IEnumerator routine){       while(State == CoroutineState.WAITTING){          yield return null;       }       while(State == CoroutineState.RUNNING){          if(State == CoroutineState.PASUED){             yield return null;          }else{             if(routine!=null&&routine.MoveNext()){                   yield return routine.Current;             }else{                   State = CoroutineState.STOP;             }          }       } }}CoroutineCtrl

using System.Collections;using UnityEngine;public class CoroutineCtrl{ private static int _id; public int ID{get;private set;} private CoroutineItem _item; private MonoBehaviour _mono; private IEnumerator _routine; private Coroutine _coroutine; public CoroutineCtrl(MonoBehaviour mono, IEnumerator routine) {       _item = new GameObject().AddComponent<CoroutineItem>();       _mono = mono;       _routine = routine;       ResetData(); } public void Start() {       _item.State = CoroutineItem.CoroutineState.RUNNING;       _coroutine = _mono.StartCoroutine(_item.Body(_routine)); } public void Pause() {       _item.State = CoroutineItem.CoroutineState.PASUED; } public void Stop() {       _item.State = CoroutineItem.CoroutineState.STOP; } public void Continue() {       _item.State = CoroutineItem.CoroutineState.RUNNING; } public void ResetStart() {       if(_coroutine != null){          _mono.StopCoroutine(_coroutine);       }       Start(); } private void ResetData(){       ID = _id++; }}CoroutineMgr

using System.Collections;using System.Collections.Generic;using UnityEngine;public class CoroutineMgr : MonoSingleton<CoroutineMgr>{ private Dictionary<int,CoroutineCtrl> _ctrlDic; public CoroutineMgr(){       _ctrlDic = new Dictionary<int, CoroutineCtrl>(); } public int Execute(IEnumerator routine,bool autoStart = true){       CoroutineCtrl ctrl = new CoroutineCtrl(this,routine);       _ctrlDic.Add(ctrl.ID,ctrl);       if(autoStart){          StartExecute(ctrl.ID);       }             return ctrl.ID; } public void ExecuteOnce(IEnumerator routine){       CoroutineCtrl ctrl = new CoroutineCtrl(this,routine);       ctrl.Start(); } public void StartExecute(int id){       var ctrl = GetCtrl(id);       if(ctrl!=null){          ctrl.Start();       } } public void PauseExecute(int id){       var ctrl = GetCtrl(id);       if(ctrl!=null){          ctrl.Pause();       } } public void StopExecute(int id){       var ctrl = GetCtrl(id);       if(ctrl!=null){          ctrl.Stop();       } } public void RestartExecute(int id){       var ctrl = GetCtrl(id);       if(ctrl!=null){          ctrl.ResetStart();       } } private CoroutineCtrl GetCtrl(int id){       if(_ctrlDic.ContainsKey(id)){          return _ctrlDic[id];       }else{          Debug.LogError($"当前id不存在,id:{id}");          return null;       } }}MonoSingleton

//简易的Mono单例类，如无必要，代码中尽量少用using UnityEngine;public class MonoSingleton<T> : MonoBehaviour where T:MonoBehaviour{ private static T _instance; public static T Instance {       get {          if(_instance == null)          {             GameObject go = new GameObject(typeof(T).Name);             DontDestroyOnLoad(go);             _instance = go.AddComponent<T>();          }          return _instance;       } }}测试

using System.Collections;using UnityEngine;using UnityEngine.UI;public class CoroutineTest : MonoBehaviour{ public Button mBtnStart; public Button mBtnPause; public Button mBtnStop; private int id = 0; private void Awake() {       mBtnStart.onClick.AddListener(ClickStart);       mBtnPause.onClick.AddListener(ClickPause);       mBtnStop.onClick.AddListener(ClickStop); } private void Start() {       // CoroutineMgr.Instance.ExecueOnce(DoSomething()); 只需要执行一次，不需要控制的用这个       id = CoroutineMgr.Instance.Execute(DoSomething());//需要多次执行和管理的用这个，保存下id，用id调用控制方法 } void ClickStart() {       CoroutineMgr.Instance.RestartExecute(id); } void ClickPause() {       CoroutineMgr.Instance.PauseExecute(id); } void ClickStop() {       CoroutineMgr.Instance.StopExecute(id); } IEnumerator DoSomething() {       print($"当前携程ID为{id}");       print("协程开始");       var timer = 0;       while ( timer<30)       {          yield return new WaitForSeconds(1);          timer++;          print($"协程进行第{timer}秒");       }       print("协程完成"); }}
