unity之通用FSM有限状态机 —>流程管理的使用（二）

上图：

 

流程管理类，其他比较简单，直接继承 FsmState即可

using System;

/// <summary>
/// 状态枚举
/// </summary>
public enum TestProcedureStateEnum
{
    Launch = 0,
    CheckVersion = 1,
    Preload = 2,
    ChangeScene = 3,
    LogOn = 4,
    SelectRole = 5,
    EnterGame = 6,
    PVE = 7,
    PVP = 8,
}

public class TestProcedureManager : IDisposable
{
    /// <summary>
    /// 当前状态机
    /// </summary>
    public TestFsm<TestProcedureManager> CurrFsm { get; private set; }

    /// <summary>
    /// 当前状态机的状态
    /// </summary>
    public TestFsmState<TestProcedureManager> CurrFsmState { get; private set; }

    /// <summary>
    /// 当前状态的枚举
    /// </summary>
    public TestProcedureStateEnum CurrStateEnum { get; private set; }

    private readonly TestFsmState<TestProcedureManager>[] m_Status = null;
    public TestProcedureManager()
    {
        m_Status = new TestFsmState<TestProcedureManager>[Enum.GetValues(typeof(TestProcedureStateEnum)).Length];
    }

    public void Init()
    {
        m_Status[(int)TestProcedureStateEnum.Launch] = new TestProcedureLaunch();
        m_Status[(int)TestProcedureStateEnum.CheckVersion] = new TestProcedureCheckVersion();
        m_Status[(int)TestProcedureStateEnum.Preload] = new TestProcedurePreload();
        m_Status[(int)TestProcedureStateEnum.ChangeScene] = new TestProcedureChangeScene();
        m_Status[(int)TestProcedureStateEnum.LogOn] = new TestProcedureLogOn();
        m_Status[(int)TestProcedureStateEnum.SelectRole] = new TestProcedureSelectRole();
        m_Status[(int)TestProcedureStateEnum.EnterGame] = new TestProcedureEnterGame();
        m_Status[(int)TestProcedureStateEnum.PVE] = new TestProcedurePVE();
        m_Status[(int)TestProcedureStateEnum.PVP] = new TestProcedurePVP();
        CurrFsm = TestGameEntry.FsmMgr.CreateFsm(this, m_Status);
        if (CurrFsm != null)
        {
            CurrFsmState = CurrFsm.GetState(CurrFsm.CurrState);
            CurrStateEnum = (TestProcedureStateEnum)CurrFsm.CurrState;
        }
    }

    public void ChangeState(TestProcedureStateEnum state)
    {
        if (CurrFsm != null)
        {
            CurrFsm.ChangeState((sbyte)state);
        }
    }

    public void OnUpdate()
    {
        if (CurrFsm != null)
        {
            CurrFsm.OnUpdate();
        }
    }

    public void Dispose()
    {
        if (CurrFsm != null)
        {
            CurrFsm.ShutDown();
        }
    }

}

测试用例：

Q键：进入启动    W键：进入检查更新    E键：进入进入游戏

void Update()
    {
        if (Input.GetKeyUp(KeyCode.Q))
        {
            TestGameEntry.ProcedureMgr.ChangeState(TestProcedureStateEnum.Launch);
        }

        if (Input.GetKeyUp(KeyCode.W))
        {
            TestGameEntry.ProcedureMgr.ChangeState(TestProcedureStateEnum.CheckVersion);
        }

        if (Input.GetKeyUp(KeyCode.E))
        {
            TestGameEntry.ProcedureMgr.ChangeState(TestProcedureStateEnum.EnterGame);
        }
    }

 

可看到 状态的进入 执行 离开。

 

是不是感觉像工厂的流水作业一样，逻辑清晰，流程解耦、一目了然。
