unity之通用FSM有限状态机 —>流程管理的使用（二）
上图：
启动流程、检查更新流程 ... 游戏关卡流程 等等 全部继承自流程基类，而流程又属于状态的一种，所以流程基类继承 父类FsmState。
流程属于状态，状态需要有一个拥有者来进行管理，切换状态。那么流程的拥有者就是流程管理器。
流程管理类：
1 using System;
2
3 /// <summary>
4 /// 状态枚举
5 /// </summary>
6 public enum TestProcedureStateEnum
7 {
8 Launch = 0,
9 CheckVersion = 1,
10 Preload = 2,
11 ChangeScene = 3,
12 LogOn = 4,
13 SelectRole = 5,
14 EnterGame = 6,
15 PVE = 7,
16 PVP = 8,
17 }
18
19 public class TestProcedureManager : IDisposable
20 {
21 /// <summary>
22 /// 当前状态机
23 /// </summary>
24 public TestFsm<TestProcedureManager> CurrFsm { get; private set; }
25
26 /// <summary>
27 /// 当前状态机的状态
28 /// </summary>
29 public TestFsmState<TestProcedureManager> CurrFsmState { get; private set; }
30
31 /// <summary>
32 /// 当前状态的枚举
33 /// </summary>
34 public TestProcedureStateEnum CurrStateEnum { get; private set; }
35
36 private readonly TestFsmState<TestProcedureManager>[] m_Status = null;
37 public TestProcedureManager()
38 {
39 m_Status = new TestFsmState<TestProcedureManager>[Enum.GetValues(typeof(TestProcedureStateEnum)).Length];
40 }
41
42 public void Init()
43 {
44 m_Status[(int)TestProcedureStateEnum.Launch] = new TestProcedureLaunch();
45 m_Status[(int)TestProcedureStateEnum.CheckVersion] = new TestProcedureCheckVersion();
46 m_Status[(int)TestProcedureStateEnum.Preload] = new TestProcedurePreload();
47 m_Status[(int)TestProcedureStateEnum.ChangeScene] = new TestProcedureChangeScene();
48 m_Status[(int)TestProcedureStateEnum.LogOn] = new TestProcedureLogOn();
49 m_Status[(int)TestProcedureStateEnum.SelectRole] = new TestProcedureSelectRole();
50 m_Status[(int)TestProcedureStateEnum.EnterGame] = new TestProcedureEnterGame();
51 m_Status[(int)TestProcedureStateEnum.PVE] = new TestProcedurePVE();
52 m_Status[(int)TestProcedureStateEnum.PVP] = new TestProcedurePVP();
53 CurrFsm = TestGameEntry.FsmMgr.CreateFsm(this, m_Status);
54 if (CurrFsm != null)
55 {
56 CurrFsmState = CurrFsm.GetState(CurrFsm.CurrState);
57 CurrStateEnum = (TestProcedureStateEnum)CurrFsm.CurrState;
58 }
59 }
60
61 public void ChangeState(TestProcedureStateEnum state)
62 {
63 if (CurrFsm != null)
64 {
65 CurrFsm.ChangeState((sbyte)state);
66 }
67 }
68
69 public void OnUpdate()
70 {
71 if (CurrFsm != null)
72 {
73 CurrFsm.OnUpdate();
74 }
75 }
76
77 public void Dispose()
78 {
79 if (CurrFsm != null)
80 {
81 CurrFsm.ShutDown();
82 }
83 }
84
85 }
流程基类，拥有者就是流程管理器 TestProcedureManager
public class TestProcedureBase : TestFsmState<TestProcedureManager>
{
}
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
1 void Update()
2 {
3 if (Input.GetKeyUp(KeyCode.Q))
4 {
5 TestGameEntry.ProcedureMgr.ChangeState(TestProcedureStateEnum.Launch);
6 }
7
8 if (Input.GetKeyUp(KeyCode.W))
9 {
10 TestGameEntry.ProcedureMgr.ChangeState(TestProcedureStateEnum.CheckVersion);
11 }
12
13 if (Input.GetKeyUp(KeyCode.E))
14 {
15 TestGameEntry.ProcedureMgr.ChangeState(TestProcedureStateEnum.EnterGame);
16 }
17 }
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。
