Java小程序之山寨版超级玛丽

1、Java小程序之山寨版超级玛丽一、游戏基本功能1、能够向左向右行走（键盘监听）2、能够跳跃3、能够发射子弹4、能够检测和障碍物之间的碰撞5、背景图片的移动二、游戏运行界面三、游戏大致实现思路：1.窗体2.自己角色的添加3.背景图片的添加4.背景图片的移动5.人物的移动和跳跃6.砖头、水管等等障碍物的添加7.任务和障碍物的碰撞难点分析：1.人物的多键控制1）给人物设定方向boolean变量：向左、向右、向上、向下2）通过键盘监听来修改方向的变量值 按下某个键的时候，我们把相应方向改为true，释放的时候改false2.地图配置自定义文件读取方式实现：文件流的使用和字符串String类的方法调用3

2、.碰撞检测封装一个Rectangle类的对象4.子弹添加1）先定义一个容器，这个用于封装所有的子弹对象2）按下某个键的时候，创建一个子弹对象（以角色的坐标为基准初始化）3）把子弹对象添加到容器当中4）在paint方法中，遍历容器，取出子弹对象并进行绘制5）检测子弹如果超出了窗体边界，则需要把当前子弹从容器当中移除掉四、程序源代码：代码结构图：分了三个包、敌人类包、游戏界面类包、游戏地图配置包com.huaxin.mario包：java view plain copy print?在CODE上查看代码片派生到我的代码片package com.huaxin.mario; import java.a
