概述:华容道
Java 华容道完整源码,本代码实现华容道游戏的整体功能。程序执行后,点击相应的人物,然后按上下左右键可以移动。点击重新开始按钮,可以将各个人物的位置重置。如果目的地的面积能够容得下当前要移动的人物,则认为可以移动。当sfdwdm移动到“sfdwdm到达该位置”的位置的时候,认为程序结束。
本示例中,利用Java的图形技术和消息响应机制完成了三国游戏华容道的制作。通过图形界面的技术,完成了用户提示和颜色设置。通过运用Windows下程序的键盘事件的响应,很好的实现了用户动作判断。

打开计算机的命令提示符窗口,然后在命令提示符窗口中,定位到javaprograms目录,输入javac HuaRongRoad.java 来编译程序,最后将程序加载到网页上。在javaprograms文件夹下新建一个记事本文件,内容为:
然后保存为HuaRongRoad.html,用浏览器打开HuaRongRoad.html文件便可以看到制作效果。
