Flex Mobile 4.6 TIC TAC TOE计算机移动 [英] Flex Mobile 4.6 TIC TAC TOE Computer Move
本文介绍了Flex Mobile 4.6 TIC TAC TOE计算机移动的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个Flex 4.6移动问题.屏幕上有9个框.当我单击第一个框(使用ID名称命名)时，它应该放置文本 X .我想要的是计算机通过插入 O 在其余的一个框中生成下一步动作.我相信您应该使用math.random还是数组?这是一个Tic Tac Toe游戏.
I have a Flex 4.6 mobile problem. I have 9 boxes on the screen. When I click on the first box (named using an ID name), it should place the text X. What I want is for the computer to generate the next move in one of the remaining boxes by inserting an O. I believe you should use math.random or an array? It's for a Tic Tac Toe game.
任何帮助将不胜感激.
谢谢.
推荐答案
我在html/javascript中做到了这一点，是使用minimax AI的井字游戏的示例，希望它可以作为Flex的参考实现项目(要进行测试，只需将代码复制并粘贴到空白html文档中，然后使用您喜欢的浏览器运行它即可):
I made this in html/javascript, is an example of a tic-tac-toe game using minimax AI, hope it helps as a reference implementation for your flex project (to test it, just copy and paste the code in blank html document and run it with your favorite browser):
