ARM7 坦克大战实验报告 嵌入式

1、嵌入式课程设计实验报告 -坦克大战学 院： 信息电子学院 班 级： 07电信实验班 组 员： 铁舰 电子工程师指导老师： 日 期： 2012年12月20日 目录一、实验目的3二、游戏内容简介3三、原理分析与代码3四、游戏结果17五、改进预想方案17六、收获与体会18一、 实验目的1、通过本次实验熟练掌握嵌入式开发板的应用；2、通过开发小游戏提高编程能力，培养严谨的编程思维；二、 游戏内容简介 本游戏初始画面为一片草地，中间隔着一条河流，河的两边各一辆坦克，左边坦克为我方，右边为敌方，坦克上方各显示五滴血量，屏幕左上角显示坦克炮筒的调整角度。进入界面即可开始游戏。游戏采取回合制。每一回合均由我方

2、坦克先进行攻击，攻击前可移动坦克位置并调整炮筒角度，如果击中敌方坦克即消耗其一滴血量，然后无论击中与否，敌方坦克将随机移动至另一位置并且攻击我方坦克一次，如若击中消耗我方坦克一滴血量，然后无论击中与否此回合将结束。下一回合与之类似。如此下去，看哪方坦克血量先被扣完，如果我方胜利，则将出现“WIN”界面，将发射键可继续玩；如果敌方胜利，则屏幕将花屏，同样按发射键可重玩。数字键和可移动坦克，和可调整坦克炮筒角度，enter为发射键。三、 原理分析与代码本次设计包括三个模块，分别为游戏界面初始化模块，游戏模块，及游戏结束显示模块。主程序流程图如下图所示：其中，游戏模块playgame流程框图如下图所
