Java布谷鸟闯关游戏
小虚竹and掘金 人气:0前言
《布谷鸟闯关-升级版》是一个基于java的布谷鸟闯关游戏，鼠标左键点击控制鸟的位置穿过管道间的缝隙，需要做碰撞检测，监听键盘事件，背景图片的切换，障碍物管道产生时y轴上需要随机位置。
主要设计
1.设计游戏界面，用swing实现
2.设计背景
3.设计移动墙
4.设计布谷鸟
5.设计障碍物
6.设计背景音乐和音效
7.新增用户账号注册登录功能
8.引用mysql数据库，管理用户账号密码和储存排行榜等信息
- 需要提前创建好数据库"game",字符集选“utf8mb4”
- 然后执行mysql表结构和初始化数据脚本
- 修改代码里的DBUtils的参数值
9.新增游戏商城模块
10.新增排行榜模块

}总结
通过此次的《布谷鸟闯关-升级版》实现，让我对JAVA的相关知识有了进一步的了解，对java这门语言也有了比以前更深刻的认识。
java的一些基本语法，比如数据类型、运算符、程序流程控制和数组等，理解更加透彻。java最核心的核心就是面向对象思想，对于这一个概念，终于悟到了一些。
