本项目是一个基于安卓的象棋项目源码,为联网游戏而设计的。
配有java服务端,不过只能单开。
我没有测试具体的功能,感兴味的可以自己链接数据库试试吧。
下面是运行指南和开发设计文档。
本源码分为客户端和服务端客户端编译即可运行,socket连接为:127.0.0.1:9898运行服务端时,需要使用MySQL建表,建表语句如下:createdatabasechinachess;usechinachess;createtableuser(idintprimarykeyauto_increment,namechar(10)uniquenotnull,passwordchar(16)notnull,headintdefault0,scoreintdefault0,victory_countintdefault0,defeat_countintdefault0,draw_countintdefault0,join_timedatetime)charsetutf8collateutf8_general_ci;服务端DbUtil.java里面有连接数据库的配置简单的设计文档:1.图片收集①背景图片②棋子图片③按钮图片2.音乐收集①背景音乐②按钮点击音乐③选子音乐④吃子音乐⑤走棋音乐⑥胜利音乐⑦失败音乐3.界面设计(photoshop画图)①加载界面②菜单界面④匹配界面⑤游戏界面⑥结算界面4.技术点①socket②多线程同步③MySQL连接④游戏逻辑⑤通信数据格式5.软件①Java环境②安卓开发环境(adtbundle)③MySQL5.76.数据处理byte数据头*0:分割--发往服务器*1:登陆*2.注册*3.消息*4:匹配游戏*5:走棋*6:求和*7:同意求和*8:悔棋*9:同意悔棋*10:认输*11:心跳包--发往用户*12:登陆回调*13:注册回调*14:开始游戏*15:游戏数据*16:游戏结束7.游戏规则①车走直线,不能挡车②马走日,前压马腿③象走田,前压象腿,不可越河④士空走斜一,吃走斜一,不可越将营⑤将走直一,(吃将可走直线可越将营),不可越将营⑥炮空走直线,吃走炮台⑦兵可进不可退,走直一8.绝杀(选)定义:无论怎么走,将都会被杀的棋叫做绝杀实现:扫描每个己方棋子的每一步,只要有一步致使不会死帅,就不是绝杀之棋9.智能AI(略)10.流程

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
