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。

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:
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。
相关函数:
paintHead():画小人的头
PaintLeftArm():画小人的左手
PaintRope():画绳子
PaintRightArm():画小人的右手
PaintBody():画小人的身子
paintLeftLeg():画小人的左腿
PaintRightLeg():画小人的右腿
