## Overview
本项目为Flappy bird的桌面平台版，具备原版的所有功能，且相较于原版优化了游戏难度并加入移动型水管，让游戏更具可玩性。
### 游戏玩法
游戏只需空格键即可操作，每局游戏随机刷新所有元素，小鸟受到重力作用会不断下坠，敲击空格键小鸟就会振翅向上飞，游戏过程中需要玩家控制小鸟不断飞行，并注意躲避随机生成的水管，每飞过一对水管就会得分，飞行过程中如果撞到水管或掉落在地则游戏结束。
本项目为Flappy bird的桌面平台版，具备原版的所有功能，且相较于原版优化了游戏难度并加入移动型水管，增加可玩性。
## How to play
直接运行FlappyBird.jar即可开始游戏。
游戏使用空格键操作。
每局游戏随机刷新所有元素，小鸟受到重力作用会不断下坠，敲击空格键使小鸟振翅向上飞，游戏过程中需要玩家控制小鸟不断飞行，并注意躲避随机生成的水管，每飞过一对水管就会得分，飞行过程中如果撞到水管或掉落在地则游戏结束。
