2.7.1任务描述
本任务是对“媒体播放器”的项目进行总结和测评，小组总结各自项目的长处与不足，小组成员总结自己在项目完成过程期间的成败得失，教师对项目进行最后点评与总结。测评的方式采用小组内自评、组间互评、教师总评相结合。
2.7.2任务目的
本任务的目的完成项目的总结和测评，通过完成本次任务，可以帮组学生掌握项目总结与测评的方法，提高学生文档书写能力，积累学习经验，为以后学习做准备，加强学生团队协作和与人沟通的能力。养成自我评价与学习他人的良好风气。
2.7.3任务实现
游戏设计与实践是一项复杂而庞大的工作，在选题之后，意识到过程的艰难，因为以前从来都没有接触过游戏设计，刚开始有点迷茫和彷徨。后来通过翻阅书籍和在网上查阅资料，逐渐找到了一些感觉，在老师的指导下，自己也手动编写了几个简单的游戏，打地鼠游戏和网络N子棋双人对战游戏，本文以连连看游戏为例予以说明。
本次设计初步懂得了电子游戏涉及到的有关技术、方法，包括电子游戏选题、构思、设计步骤等。并实现一些可演示的游戏软件，其中有很多应用了学习的相关技术，并且做到了界面、声音都能实际演示。此次设计过程中印象最深的收获有：1、学到了很多新知识，并且对老知识进行了回顾。经过长时间的学习，更进一步熟悉了Qt编程、通过不断上机实验，调试程序，总结经验，从对课题的不理解到能够开始动手去做，提出新问题并自己想办法去解决问题，自己多实践，所以增强了动手能力。2、提高了中、英文资料的检索能力。这次毕业设计过程中查阅了多资料，包括一些期刊、杂志，还有网络中的电子文档、电子书籍、网页及下载的视频教学课程；不但有中文资料还有英文资料。这些资料，眼界更开阔，对课题的认识更加深刻，编写程序的时候思路更加清楚，少走了很多弯路。
回顾此次设计过程，学到了许多书本上没有学到的知识。通过这次自己制作的软件，丰富了自己的实践技能，扩张了本专业的知识面，同时也体验到了搞软件开发的难度。在这次设计的同时，由于对这样的软件开发还只是一个开始，了解的不多，这其中或许还有很多的不足，有些模块做得不是很好，有些功能还不能够完全的实现，如播放背景音乐时，只能播放一遍，因为游戏Qt类库中封装的东西太多，有些函数它底层的具体实现可能还没有真正的理解，所以，这也许就是本次游戏设计的不足之处。
