Java实现游戏飞机大战-III的示例代码
作者：小虚竹and掘金
这篇文章主要为大家介绍了如何利用Java实现经典的游戏之飞机大战，文中采用了swing技术进行了界面化处理，感兴趣的小伙伴可以动手试一试
前言
《飞机大战-III》是一款融合了街机、竞技等多种元素的经典射击手游。华丽精致的游戏画面，超炫带感的技能特效，超火爆画面让你肾上腺素爆棚，给你带来全方位震撼感受，体验飞行战斗的无限乐趣。
游戏是用java语言实现，采用了swing技术进行了界面化处理，设计思路用了面向对象思想。
主要需求
基于Java Swing，以飞机大战为原形，以抗日电视剧《亮剑》中的“李云龙”为主题，实现菜单、选关、难度、等级、技能等功能。
主要设计
①进入游戏后，请按下shift键（将键盘改为英文模式）
②技能为数字1（攻击）、2（治愈）、3（蓄气）
③数字4、5、6、7、8为创意音效，空格键为暂停
④使用1、2技能会消耗相应的技能蓝条，3技能消耗一定血量恢复一定蓝
⑤触碰游戏中随机出现的降落伞弹药可以回蓝
⑥触碰游戏中随机出现的闪光粒子可以随机更换1技能特效，且血量与蓝加2
⑦由鼠标控制角色位置，角色会自动发射相应等级的子弹
⑧每打败一个boss，角色升一级，子弹同行升级
⑨每过一关，角色血量和蓝自动增大并加满
⑩按下空格暂停游戏
本游戏该版本共三个关卡和三种难度，任君挑选

}总结
通过此次的《飞机大战-III》游戏实现，让我对swing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。
以上就是Java实现游戏飞机大战-III的示例代码的详细内容，更多关于Java飞机大战的资料请关注脚本之家其它相关文章！
