unity 状态机 + svn + 码云上篇

最近刚找到在实习，忙于公司一个c++ 项目，一直想写博客来着，没时间写今天熬夜打算先献上自己前几天自己封装的一个fsm状态机

话不多说，直接上正题，这篇博客主要是在学校的时候状态机一直使用的是player maker插件或者是自己使用if else (switch case)来实现自己的状态机

所谓的状态机不过是一种数据结构，可以遵循一定的顺序的状态循环而已 (PS:自己能力有限,有不对的地方欢迎大家指出)

public delegate void FsmEvent();

public class MyState<T>
{
    private T myState;
    public string name;
    public MyState(string name,T state)
    {
        this.name = name;
        myState = state;
    }


    public Dictionary<T, MyFSMTranslation<T>> TranslationDict = new Dictionary<T, MyFSMTranslation<T>>();

 
    public event FsmEvent DoBeforeEntering;

    public void DoBeforeEntery()
    {
        if (DoBeforeEntering != null)
        {
            DoBeforeEntering();
        }
        else
        {
            Debug.Log("没有添加事件");
        }
       
    }



    public event FsmEvent DoBeforeLeaving;

    public void DoBeforeLeave()
    {
        if (DoBeforeLeaving != null)
        {
            DoBeforeLeaving();
        }
        else
        {
            Debug.Log("没有绑定事件");
        }
       
    }


    public event FsmEvent Act;

    public void DoAct()
    {
        if (Act != null)
        {
            Act();
        }
        else
        {
            Debug.Log("没有绑定事件");
        }
    }
}

解释一下自己的代码，FsmEvent是自定义的fsm的事件，MyState<T> 是泛型的状态类，包含了状态和三个事件，分别为第一次进入，一直执行，退出

 1 public class MyFSMTranslation<T>
 2 {
 3     public MyState<T> fromState;
 4     /// <summary>
 5     /// 转换状态的名字
 6     /// </summary>
 7     public string name;
 8     public MyState<T> toState;
 9 
10     /// <summary>
11     /// 状态跳转
12     /// </summary>
13     /// <param name="fromState"> 当前状态</param>
14     /// <param name="name"> 状态跳转的名字</param>
15     /// <param name="toState"> 下一个要进入的状态</param>
16     public MyFSMTranslation(MyState<T> fromState, MyState<T> toState, string name = null)
17     {
18         fromState = fromState;
19         toState = toState;
20         name = name;
21     }
22 }

这是一个状态跳转类注释很详细就不解释了

重点到了

  1 public class FSMS<T>
  2 {
  3 
  4     private T myFsmType;
  5     public T FsmType
  6     { 
  7         get
  8         {
  9             return myFsmType;
 10         }
 11         
 12     }
 13 
 14     public string StateName
 15     {
 16         get
 17         {
 18             return StateDict[myFsmType].name;
 19         }
 20     }
 21 
 22 
 23     // 状态存贮
 24     Dictionary<T, MyState<T>> StateDict = new Dictionary<T, MyState<T>>();

 57             nextstate = StateDict[nextType];
 58         }
 59         else
 60         {
 61             return false;
 62         }
 63         if (StateDict[myFsmType].TranslationDict.ContainsKey(nextType))
 64         {
 65 
 66             //当期状态转换之后执行的函数
 67             //当期状态转换
 68             //下一个状态需要执行的函数
 69             //改变类里面的状态
 70             StateDict[myFsmType].DoBeforeLeave();
 71             myFsmType = nextType;
 72             nextstate.DoBeforeEntery();
 73 
 74         }
 75         else
 76         {
 77             return false;
 78         }
 79

 89         nextstate.DoAct();
 90     }
 91 
 92 
 93     /// <summary>

 96     public void Start(T fsmtype)

上面都有注释，就不在解释了，大家感觉有不对的地方欢迎指出
