使用QT开发2048小游戏

众所周知……在雷课堂后大部分人都掌握了QT界面的能力。 本着浪费人生与无聊写游戏的宗旨，我决定用QT写一个2048玩玩。（以后可能还会更新黑白棋和五子棋哟！） 那么2048其实难度不大，主要考虑几个点，一个是刷新，需要随机更新2或4，一个是堆叠和合并，因为堆叠过程中由于可能出现一行4个2这些情况，所以合并后要再次堆叠。于是乎，首先需要一个游戏界面，一个游戏核心类，外加一个主界面。所以QT先是把Mainwindow设计好，然后处理游戏。 在这过程中还要进行打分，并且还自带了log类似的功能。 先看看总体是这样! 那么再看看核心类 gamecore.h

class gamecore { public: gamecore(); //构造函数 ~gamecore(); //析构函数 void RESET(); //初始化棋盘 int judgewin(); //分析是否胜利，返回值为1则胜利，0则未胜利，2则输 bool push(char x); //推动数字，若能推动则堆叠并返回1，否则返回0表示无法堆叠 bool mix(char x); //将可能可合并的数字合并 void create(); //随机生成一个数字在空白区域，可能为2或4 int getcurrentscore();//获取当前分数 int gethighestscore();//获取当前最高分 bool savetodata(); //保存游戏 int board[4][4]; //棋盘 private: int highest_score; //记录历史最高分 int current_score; //记录当前分数 QString situation; //记录游戏情况，类似于log }; #endif // GAMECORE_H

emmm是不是非常浅显易懂。 对于玩游戏的play界面，主要问题一个是显示，要把board上的数字显示到QLabel上，同时还要把颜色标清楚，所以有点麻烦（超级麻烦 但感谢我健壮有力的肝和搬砖的决心，即使不知道怎么ui传参，我也硬怼出来了 下面放上我惨不忍睹的代码……○|￣|_ play.h
