状态机高阶讲解-16

2534
01:44:41,942 --> 01:44:44,140
那我们，你看这里

2535
01:44:45,170 --> 01:44:46,452
你看这里改之后

2536
01:44:46,452 --> 01:44:48,833
它代码就做新的调整了嘛

2537
01:44:48,833 --> 01:44:49,200
对吧

2538
01:44:50,150 --> 01:44:51,180
调整

2539
01:44:51,460 --> 01:44:52,189
同样的

2540
01:44:52,189 --> 01:44:54,740
我们也试一下，这些有没有问题

2541
01:44:54,740 --> 01:44:57,110
我们敲的代码有没有没问题

2542
01:44:57,890 --> 01:44:59,369
还有这个操作

2543
01:44:59,369 --> 01:45:00,637
有没有问题

2544
01:45:00,637 --> 01:45:01,060
生成

2545
01:45:08,520 --> 01:45:08,814

2546
01:45:08,814 --> 01:45:11,760
这里面它说什么那个

2547
01:45:12,430 --> 01:45:13,360

2548
01:45:16,020 --> 01:45:20,470
这个print里面缺少在什么前面

2549
01:45:20,750 --> 01:45:21,005

2550
01:45:21,005 --> 01:45:23,302
非法命名空间字符

2551
01:45:23,302 --> 01:45:25,598
那这里有问题了

2552
01:45:25,598 --> 01:45:25,854

2553
01:45:25,854 --> 01:45:27,130
刚才我们

2554
01:45:27,520 --> 01:45:27,860

2555
01:45:27,860 --> 01:45:29,560
敲错了，是吧

2556
01:45:33,180 --> 01:45:33,358

2557
01:45:33,358 --> 01:45:35,500
这个地方，看什么地方有问题

2558
01:45:40,020 --> 01:45:40,255

2559
01:45:40,255 --> 01:45:41,900
少了个冒号

2560
01:45:43,190 --> 01:45:44,380

2561
01:45:46,390 --> 01:45:47,700
这个地方

2562
01:45:47,700 --> 01:45:50,320
看有没有问题

2563
01:45:50,600 --> 01:45:50,817
好

2564
01:45:50,817 --> 01:45:51,470
确定

2565
01:45:51,470 --> 01:45:52,559
再来一遍

2566
01:45:52,559 --> 01:45:53,430
再来一遍

2567
01:46:08,900 --> 01:46:09,140
好

2568
01:46:09,140 --> 01:46:10,100
构建完成

2569
01:46:10,100 --> 01:46:11,540
你看，已搞定

2570
01:46:11,540 --> 01:46:14,660
就是说，这个对象已经生成了

2571
01:46:14,970 --> 01:46:16,570
已搞定这个地方

2572
01:46:18,270 --> 01:46:22,852
那么接下来呢，就要给它添加状态机了

2573
01:46:22,852 --> 01:46:24,200
怎么添加

2574
01:46:24,630 --> 01:46:24,889

2575
01:46:24,889 --> 01:46:26,702
右键点这个类了

2576
01:46:26,702 --> 01:46:27,220

2577
01:46:28,330 --> 01:46:31,220
新增，状态图，这里

2578
01:46:35,470 --> 01:46:36,330
好

2579
01:46:36,610 --> 01:46:39,260
得到一张空白的状态图了

2580
01:46:40,140 --> 01:46:42,546
那首先要放上一个状态

2581
01:46:42,546 --> 01:46:45,610
你看，工具栏这里，状态，点中这个

2582
01:46:47,210 --> 01:46:49,550
按住Ctrl，滚轮放大一点

2583
01:46:50,110 --> 01:46:50,374

2584
01:46:50,374 --> 01:46:52,223
状态名字我们叫

2585
01:46:52,223 --> 01:46:53,280
比如说，叫

2586
01:46:54,120 --> 01:46:55,020
Active

2587
01:46:58,620 --> 01:46:59,630
活跃的

2588
01:47:00,830 --> 01:47:01,134
好

2589
01:47:01,134 --> 01:47:02,353
这个有了

2590
01:47:02,353 --> 01:47:05,400
那我们再加一个缺省的

2591
01:47:06,570 --> 01:47:07,131
转换

2592
01:47:07,131 --> 01:47:08,440
它这里叫转换

2593
01:47:08,440 --> 01:47:10,310
我们平时叫迁移

2594
01:47:13,150 --> 01:47:13,889
点中这个

2595
01:47:13,889 --> 01:47:15,922
但是你看，点这里的话

2596
01:47:15,922 --> 01:47:17,585
它不出现一个黑点

2597
01:47:17,585 --> 01:47:19,434
EA里面是什么

2598
01:47:19,434 --> 01:47:20,543
点这里出现黑点

2599
01:47:20,543 --> 01:47:21,467
然后再拉过来

2600
01:47:21,467 --> 01:47:23,130
它这个，点不行的

2601
01:47:23,130 --> 01:47:23,870
你还得指向

2602
01:47:24,150 --> 01:47:27,686
某个，指向认定这个是

2603
01:47:27,686 --> 01:47:30,211
这是缺省状态

2604
01:47:30,211 --> 01:47:31,980
点中这个才有

2605
01:47:32,820 --> 01:47:33,079
好

2606
01:47:33,079 --> 01:47:36,450
就得到了一个缺省的迁移了

2607
01:47:39,030 --> 01:47:41,820
那我们就要对这个缺省的迁移

2608
01:47:43,540 --> 01:47:44,670
来

2609
01:47:46,640 --> 01:47:50,320
配置一下迁移的内容

2610
01:47:50,770 --> 01:47:56,933
那就是进入这个初始的这个缺省状态的时候

2611
01:47:56,933 --> 01:47:59,399
我们先设置这个属性

2612
01:47:59,399 --> 01:48:00,632
属性是哪个

2613
01:48:00,632 --> 01:48:02,851
是count那个

2614
01:48:02,851 --> 01:48:05,070
这个属性嘛

2615
01:48:07,370 --> 01:48:08,930
设这个属性的值

2616
01:48:09,210 --> 01:48:09,477

2617
01:48:09,477 --> 01:48:10,280
比如说

2618
01:48:11,880 --> 01:48:12,947
怎么设置

2619
01:48:12,947 --> 01:48:15,082
你看双击这个迁移

2620
01:48:15,082 --> 01:48:16,150
然后这里

2621
01:48:19,590 --> 01:48:21,091
在这个地方

2622
01:48:21,091 --> 01:48:22,163
这里叫操作

2623
01:48:22,163 --> 01:48:23,236
这个不对的

2624
01:48:23,236 --> 01:48:24,952
应该是动作，action

2625
01:48:24,952 --> 01:48:27,525
所以这个翻译是有问题的

2626
01:48:27,525 --> 01:48:32,030
可能是他们IBM中国公司的人翻译的这个

2627
01:48:32,720 --> 01:48:34,724
不知道找什么人翻译的

2628
01:48:34,724 --> 01:48:35,560
不知道了

2629
01:48:35,970 --> 01:48:36,181

2630
01:48:36,181 --> 01:48:37,452
这是action

2631
01:48:37,452 --> 01:48:40,630
它把它跟operation混在一起了

2632
01:48:42,700 --> 01:48:42,942

2633
01:48:42,942 --> 01:48:44,636
比如说，我们代码

2634
01:48:44,636 --> 01:48:47,300
count

2635
01:48:48,000 --> 01:48:49,252
=10

2636
01:48:49,252 --> 01:48:51,130
一开始是10嘛

2637
01:48:52,790 --> 01:48:54,070

2638
01:48:54,630 --> 01:48:54,935
好

2639
01:48:54,935 --> 01:48:55,241

2640
01:48:55,241 --> 01:48:56,770
然后呢

2641
01:48:57,050 --> 01:48:58,000
print 

2642
01:49:00,710 --> 01:49:01,057

2643
01:49:01,057 --> 01:49:02,100
已开始

2644
01:49:03,020 --> 01:49:03,950

2645
01:49:08,690 --> 01:49:08,882

2646
01:49:08,882 --> 01:49:09,650
类似这样

2647
01:49:11,470 --> 01:49:12,230
好

2648
01:49:12,230 --> 01:49:12,990
OK
