• 贪吃蛇游戏和俄罗斯方块

    一、创建新项目

    创建一个新的项目，并命名。

    创建一个名为images的文件夹用来存放游戏相关图片。

    然后再在项目的src文件下创建一个com.xxx.view的包用来存放所有的图形界面类，

    创建一个com.xxx.controller的包用来存放启动的入口类(控制类)

    俄罗斯方块
    游戏规则：
    由小方块组成的不同形状的板块陆续从屏幕上方落下来，玩家通过调整板块的位置和方向，使它们在屏幕底部拼出完整的一条或几条。这些完整的横条会随即消失，给新落下来的板块腾出空间，与此同时，玩家得到分数奖励。没有被消除掉的方块不断堆积起来，一旦堆到屏幕顶端，玩家便告输，游戏结束。

    整体代码分为三个模块：方格模块，七种图形模块，俄罗斯方块主模块。

    三、效果展示

    规则

    按下空格键，方块瞬间下落， 按下P键游戏暂停，消除一行分数为1（此处由分数池进行控制）

      按下C键游戏继续。

    方块占满，游戏结束，此时可以按下S键重新开始游戏
