状态机框架

封装传递的数据类型

public class StateDeve
{
public Type type;//类型
public object data;//任意数据

//回调类型自己就是自己
public static StateDeve Creat(Type type, object data) {
    StateDeve state = new StateDeve();
    state.type = type;
    state.data = data;
    return state;
}

}

状态的基类

public abstract class StateBase
{
public abstract int ID { get; }
public abstract void Enter(StateDeve stateDeve);//开始
public abstract void Stye (StateDeve stateDeve);//执行中
public abstract void Exite(StateDeve stateDeve);//结束
}

状态机
public class FsmCure
{
public StateBase curstateBase;//当前状态
public StateBase pvrstateBase;//上一个状态

public StateDeve date;//类型

public void Change(StateBase state,StateDeve curdate,StateDeve pvrdata) {
   
    if (curstateBase != null && state.ID == curstateBase.ID) return;
    //结束状态
    if (pvrstateBase != null) pvrstateBase.Exite(pvrdata);
    //当前状态为传进来的类型
    curstateBase = state;
    //类型为当前类型
    date = curdate;
    //开始
    curstateBase.Enter(date);
}

/// <summary>
/// 为执行Change方法
/// </summary>
/// <param name="state"></param>
/// <param name="curdate"></param>
/// <param name="pvrdata"></param>
public void Start(StateBase state, StateDeve curdate, StateDeve pvrdata)
{
    Change(state,curdate,pvrdata);
}
/// <summary>
/// 执行中的状态
/// </summary>
public void Update()
{
    if (curstateBase == null) return;
    curstateBase.Equals(date);
}

}

例子 某个脚本调用等待状态
public class FsmModle : MonoBehaviour
{
FsmCure fsm;//状态机控制

FsmGame fsmgo;//封装的 this 类

StateDeve fsdata;//封装的类型

public void Init()
{
    fsm = new FsmCure();
    fsmgo = new FsmGame();

    //获取本身的动画
    fsmgo.anim = this.GetComponent<Animator>();
    //获取本身
    fsmgo.obj = this.gameObject;
    //获取状态机
    fsmgo.fsm = fsm;
    //把类型封装好准备传
    fsdata = StateDeve.Creat(fsmgo.GetType(),fsmgo);
}


// Start is called before the first frame update
void Start()
{
    //调用初始化
    Init();

    fsm.Start(new Idle(),fsdata,null);
   


}

// Update is called once per frame
void Update()
{
    
}

}
//定义一个本身类
public class FsmGame {
public Type type = typeof(FsmGame);
public Animator anim;
public GameObject obj;
public FsmCure fsm;

}

例子 等待状态
public class Idle : StateBase
{

public override int ID { get {
        return 0;
    } }

public override void Enter(StateDeve stateDeve)
{
FsmGame fsmGame=(stateDeve.data) as FsmGame;
//fsmGame.anim.(…);动画随意
Debug.Log(“1”);
}

public override void Exite(StateDeve stateDeve)
{
    FsmGame fsmGame = (stateDeve.data) as FsmGame;
    //fsmGame.anim.(.......);动画随意
    Debug.Log("3");
}

public override void Stye(StateDeve stateDeve)
{
    FsmGame fsmGame = (stateDeve.data) as FsmGame;
    //fsmGame.anim.(.......);动画随意
    Debug.Log("2");
}

}
