1、Java小程序之山寨版超級瑪麗一、游戲基本功能1、能夠向左向右行走（鍵盤監聽）2、能夠跳躍3、能夠發射子彈4、能夠檢測和障礙物之間的碰撞5、背景圖片的移動二、游戲運行界面三、游戲大致實現思路：1.窗體2.自己角色的添加3.背景圖片的添加4.背景圖片的移動5.人物的移動和跳躍6.磚頭、水管等等障礙物的添加7.任務和障礙物的碰撞難點分析：1.人物的多鍵控制1）給人物設定方向boolean變量：向左、向右、向上、向下2）通過鍵盤監聽來修改方向的變量值 按下某個鍵的時候，我們把相應方向改為true，釋放的時候改false2.地圖配置自定義文件讀取方式實現：文件流的使用和字符串String類的方法調用3

2、.碰撞檢測封裝一個Rectangle類的對象4.子彈添加1）先定義一個容器，這個用于封裝所有的子彈對象2）按下某個鍵的時候，創建一個子彈對象（以角色的坐標為基準初始化）3）把子彈對象添加到容器當中4）在paint方法中，遍歷容器，取出子彈對象并進行繪制5）檢測子彈如果超出了窗體邊界，則需要把當前子彈從容器當中移除掉四、程序源代碼：代碼結構圖：分了三個包、敵人類包、游戲界面類包、游戲地圖配置包com.huaxin.mario包：java view plain copy print?在CODE上查看代碼片派生到我的代碼片package com.huaxin.mario; import java.a
