Java实现升级版布谷鸟闯关游戏的示例代码

时间：2022-11-10 09:22:17|栏目：JAVA代码|点击：次

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
