1.新建一个普通的java项目
2.新建一个文件夹imags是用来放图片素材
3.在src创建一个文件夹com.sxt是用来放实体类的
步骤
1.窗口绘制
2.绘制图片
3.线绘制
4.线摇摆
5.线抓取
6.创建金块
7.双缓存
8.抓取判定
9.抓取返回
10.创建多个金块
11.石块创建
12.拉取速度
13.创建多种金块
14.物体堆叠
15.线完善
16.积分设置
17.爆破
18.关卡设置
19.游戏状态
20.游戏计时效果
21.成功效果
22.失败效果
23.游戏重置效果
24.商店购物效果
4.在com.sxt文件夹创建六个实体类Bg、Gametest、Gold、line、Object、Rock
