实现目的

2048，作为一款极其经典的游戏，从发行到现在，已经有了极多的版本和玩法，各种优秀应用游戏层出不穷。

本游戏注重"视觉展现效果和更快速的动画"、注重数据储存，是一种对于算法和 UI 设计有一定要求的应用设计。

本小组秉承课程所学与外部优秀知识技术相结合的观念，多人合作，共同研究学习。

以 C 语言为基础、C++ 语言库函数为辅助、Windows 程式应用编程和状态机思想为框架、搜索和多线程运行等算法知识为技术核心。

游戏玩法介绍

选择上下左右任何一个方向去滑动
每滑动一次，所有的数字方块都会往滑动的方向靠拢外
系统在滑动之后会在空白的地方随机出现一个数字方块（一般是2或4）
相同数字的方块会相加成一个数字
不断的叠加最终拼凑出2048这个数字就算成功。

实现流程与作品架构

使用 Windows 窗口编程，创建窗口
在消息循环中创建 Game 程序实现主体，使用 C++ 语言中new 创建 Game 类，用于游戏的初始化
Game 类包含以下内容
- 窗口创建时的一些属性
- 游戏初始化部分
- 游戏运行时四个方向的移动函数
- 移动判断函数
- 图片的绘制函数
定时器的程序运行
游戏移动消息循环接受和对应操作的实现
在不断进行的消息循环中，进行绘图的操作（不停的擦除和重绘）

总结感想

JingWenxing's

这次课程设计，是编程生涯的第一次多人合作。虽然之前对于多人合作有一定的感想和思考，但是实践出真知，我还是发现了很多问题。

作为一个多人合作的队伍，首先需要的就是任务的细化和代码沟通的通常。这点我们并没有做的很好。任务一直没有很好的定下来，并且个人任务混杂，互相干涉，效率不高。代码沟通上之前并没有使用“码云”，导致每次都要自行寻找各版本中的不同之处。

除此之外就是任务逾期的问题。几乎所有的项目，都没有在规定的时间内完成，都有多多少少的拖沓情况。这在多人合作中是致命的。这也是今后需要极为注意的地方

自身的知识水平和技术也是一大问题。“现学现用”在本次合作中可以说是贯穿全场。不论是C+＋、Windows，还是EasyX，状态机。虽然学习了新的东西收获慢慢，但是仍然发现了自己技术上的不足。

暑假里我将完成以下的学习，继续深造：

学习任务	学习任务	学习任务
计算机网络	Linux	DirectX 3D 11
Google test	Java	C / C++
算法	英语	数学

Crush‘s

在这次以小组为单位的课程设计中，我觉得有收获也有所欠缺，课程设计本身就是一个问题，需要我们小组成员一起去解决的问题，我们大家给出自己的想法和思路怎么去把这个课程设计完美的做出来，因此每个人可能需要分配一些各自的任务，然后各自去完成自己负责的部分，起初我认为这样是比较合理的。

但是在完成各自任务的过程中，我觉得还是需要大家一起去讨论才能够选出最佳方案，比如游戏的美工和界面，就需要征集大家的意见，才能确定一个适合大众口味的风格。

确定好之后再分配到个人去搜集素材并整理好，这个过程中，需要用到一些相关软件，如ps，但我们对ps的操作还是有很多不会的地方，所以还需要加强这方面的学习。

还有就是大家的积极性可能会因为无法实现自己想要表达的效果而减退，很多时候无法在规定的时间内完成任务，导致进度过慢，这点在今后的小组课程设计中一定要改正，小组成员要时刻保持绝对的积极性，面对困难不退缩，迎难而上，认真完成课程设计任务。

LILI’s

这次的课程设计是我学习专业以来，自己的第一次实际操作，在这次小组课程设计中，我学到了许多东西，也发现了许多问题，和自己的许多不足之处。

在这次设计中，我发觉最大的问题就是我们对游戏的设计并不坚定，总是一次又一次的推翻自己之前的想法。在知道要课程设计一个游戏时，首先我们对游戏的主题结构进行了构思，在第一次游戏构思时，队长和我通过天马行空的想象，将一个完整的故事线构思好了，再将其细节也进行了细化，但在实际操作的过程中，发现游戏所需素材太多，操作困难，然后迅速放弃，一切重头再来。在这期间我们浪费了许多的时间。

在游戏设计的过程中，发现自己不懂的实在是太多，所以我也在一直不断的学习（因为我就是菜鸡本菜），除了对c的知识更加深入的学习以外，我还学习了c++类等知识。虽然我还是有很多的不足，但会继续努力。
