我们知道,现在很多流行的游戏几乎都是c语言开发的,而一些小型游戏使用java开发也是可以的,毕竟java也是当今最流行的开发语言,那Java怎么写游戏下面来我们就来给大家讲解一下java写游戏脚本教程。
我们以开发扫雷游戏为例:
主要需求
1、要有难度等级,初级,中级,高级
2、由玩家逐个翻开方块,以找出所有地雷为最终游戏目标。如果玩家翻开的方块有地雷,则游戏结束
3、游戏主区域由很多个方格组成。使用鼠标左键随机点击一个方格,方格即被打开并显示出方格中的数字;方格中数字则表示其周围的8个方格隐藏了几颗雷。
4、用户右键可标记雷的位置
5、雷都被标记出来则胜利
主要设计
1、格子格数固定为10*10格
2、难度等级,初级:12,中级:24,高级:36
3、点击格子时,产生没有引爆的地图效果;
4、点击格子时,此格子是雷,则显示所有雷的位置,并递归清空非雷格子,结束游戏
5、实现检查所有的雷是否都被标记出来了,如果是,则胜利算法。
6、实现计时器算法,用来计时显示游戏开始多少秒
7、实现难度等级,雷数的显示
8、实现鼠标左键的实现逻辑
9、实现鼠标右键的标记逻辑

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。
这样我们就完成了java开发扫雷游戏的全部过程了,其实开发游戏最重要的还是逻辑,这就要求我们要掌握java的基础语法、程序流程控制等知识,只有将java该学的知识都理解并会使用,才能开发游戏!最后大家如果想要了解更多java实例知识,敬请关注奇Q工具网。
