事件系统（二）多播事件

先创建字典保存所有的事件

Dictionary<EPlayerEvt, List<Action<object, object[]>>> _phList = new Dictionary<EPlayerEvt, List<Action<object, object[]>>>();

1.事件添加

 public void addEventHandler(EPlayerEvt eventID, Action<object, object[]> handler)
    {
        if (_phList == null) return;
        if (!_phList.ContainsKey(eventID)){
            _phList[eventID] = new List<Action<object, object[]>>();
        }
        var funcList = _phList[eventID];
        if (funcList == null) return;
        funcList.Add(handler);

    }

2.事件删除

public void delEventHandler(EPlayerEvt eventID, Action<object, object[]> handler)
    {
        if (_phList.ContainsKey(eventID))
        {
            var funcList = _phList[eventID];
            var action =  funcList.Find(i=> i == handler);
            if (action != null)
            {
                funcList.Remove(action);
            }
        }
    }

3.事件触发

 public void fireEvent(EPlayerEvt eventID, object sender, object[] args)
    {
        if (_phList.ContainsKey(eventID))
        {
            var actList = _phList[eventID];
            if (actList != null)
            {
                for (int i = 0; i < actList.Count; i++)
                {
                    var item = actList[i];
                    if (item != null)
                    {
                        item(sender, args);
                    }
                }
            }
        }
    }

4.删除所有事件

 public void delAllEventHandler(EPlayerEvt eventID)
    {
        if (_phList.ContainsKey(eventID))
        {
            var funcList = _phList[eventID];
            if (funcList != null)
            {
                funcList.Clear();
            }
        }
    }

5.重置事件系统

  public void Reset()
    {
        if (_phList == null) return;
        _phList.Clear();
        _phList = null;
    }
