python做俄罗斯方块手机版下载_小游戏|用Python实现俄罗斯方块

游戏规则&＃xff1a;

由小方块组成的不同形状的板块陆续从屏幕上方落下来&＃xff0c;玩家通过调整板块的位置和方向&＃xff0c;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&＃xff0c;给新落下来的板块腾出空间&＃xff0c;与此同时&＃xff0c;玩家得到分数奖励。没有被消除掉的方块不断堆积起来&＃xff0c;一旦堆到屏幕顶端&＃xff0c;玩家便告输&＃xff0c;游戏结束。

环境

操作系统&＃xff1a;Windows

Python 版本&＃xff1a;3.6

涉及模块&＃xff1a;sys、random、PyQt5

实现

首先安装第三方模块 PyQt5&＃xff0c;使用

pip install PyQt5 即可。
