使用JavaFX完成刽子手游戏

1.1 题目说明

1.2 分析过程

本题让我画一个小人，首先使用new Arc()命令绘制半个椭圆当基座，然后使用new Line()绘制线条，line1和line2绘制杆，line3绘制绳子，然后用new Circle()命令画圆，circle当做小人的头，用line4、line5画小人的手、line6画身子和line7、line8画脚，准备做好后，创建一个Pane面板，然后使用getChildren()方法中的add()方法将所有小组件放到面板中。

2.1 题目说明

结合以上两个功能，实现动画方式的侩子手游戏，当用户猜错 7 次，绞刑架上的人摆动。当一个单词完成后，用户使用回车键继续猜下一个单词。

初始状态如下：

2.2 分析过程

创建一个名为missNum和guessNum，都为int类型的私有数据域，missNum为猜错的次数，guessNum为猜测的次数，同时声明一个名为missWord、wordMessage、word,类型为String的私有数据域，由于题目要求，当全部输出错误的时候，小人需要晃动，所以我在这里设置了两个Pane面板，一个名为pane的面板用于整体布局，一个用于名为laterPane的面板，当回答七次之后，在上面绘制小人，然后让这个面板转动起来。arc用于绘制基座，line1和lin2用于绘制杆，名为message和word的Label标签用于显示信息，一个名为info用于显示错误信息，一个名为textField的文本域供用户输入,这里使用setLayoutX()方法和setLayoutY()方法进行布局。

设置完界面之后，便开始进行事件处理，使用getText()方法获取用户在文本框中输入的信息，系统在这个使用已经调用了chooseWord()方法随机生成了一个单词，用户没进行一次猜测的时候，guessNum都会加1，当missedNum小于7的时候，判断用户输入的字母是否在单词中，如果在的话，使用for循环和if判断语句看单词中是否出现多次，使用一个字符串str存储输入的字符，如果不在的话，str加上*号，每一次输入完成后，都需要将str赋值给wordMessage,如果猜测的单词和系统产生的单词相同，则把画出相应的部分，当猜测的时候，猜错一个单词就会依次画出绳子、小人的头、左手、身子、右手、左脚、右脚，这里我使用了一个switch判断，当猜测错误一次的时候，向面板中添加绳子；当猜测错误为两次时，向面板中添加头；当猜测错误为三次时，向面板中添加左手；当猜测错误为四次时，向面板中添加身体；当猜测错误为五次时，向面板中添加右手；当猜测错误为六次时，向面板中添加左腿；当猜测错误为七次时，向面板中添加右腿；然后将这些组件添加到laterPane面板里，我在这里使用setRotate方法进行面板的旋转，newRotate()方法进行角度设置，然后一个double类型的数据。

由于无论猜测成功还是失败，我们都需要重新开始游戏，所以我设置了一个事件处理，但按下回车键并且猜测成功或猜错次数大于7次的时候，重置面板，初始错误次数为0，猜测次数为0，并且面板上有基座和杆。
