C语言项目实战：《连连看》基础项目！460 行源码注释，干货

这篇文章主要为大家详细介绍了C语言实现——《连连看》小游戏，示例代码介绍​的​非常详细，具有​想当​的参考价值，感兴趣的小伙伴们可以参考一下！

​​

​​

游戏介绍：

连连看小游戏速度节奏快，画面清晰可爱，适合细心的玩家。丰富的道具和公共模式的加入，增强游戏的竞争性。多样式的地图，使玩家在各个游戏水平都可以寻找到挑战的目标，长期地保持游戏的新鲜感。本期举例的项目类似宠物连连看，小动物造型的连连看游戏（这个主要看你准备好的图片素材）

游戏玩法

加载游戏后，点击画面中间的图像即进入游戏状态。使用鼠标左键即可，点击相同的两张图卡，用三根内的直线连在一起就可以消除。只要我们在有限的时间里，用我们智慧消除相连卡片，就可以获得最终的胜利。那么我们了解了规则之后，就动手来试试吧！

编译器：VS2013/2019最佳；

插件：图形库插件easyX，涉及图片素材可以自行百度找也可以关注文末领取；
