解释：
之前用的screentogif录屏，因为上传的.gif最大不超过5mb，所以做了不少删帧和色彩弱化等处理，这才导致色彩看上去不是很舒服，不要盯着它看太久，不然会有点难受…
由于使用的素材是现成的，没有花时间精力去扒，所以细节方面可能不是做的很好。
说明：
这次的甜品消消乐虽然看上去好像挺简单普通的，但是相对于之前的坦克大战，某种程度上已然提升难度了，归类到了算法类层的游戏。
拉到最后看代码你就能理解我的意思了，坦克大战的所有代码加起来还不如消消乐两个类的代码多，其他各种细节，坦克也只能望其项背…
如果坦克大战是低阶的，那么甜品消消乐就是中阶的，有着不少的动画效果和交互（碰撞检测和甜品的控制等），游戏运行的所有机制和功能需要在模型层上进行操控。
这次的消消乐需要一定的逻辑思维、算法基础、unity综合能力和编程基础。
方正粗圆的字体和布灵布灵的闪光特效会赋予游戏可爱风的氛围感。
我们把物体分为模型层和渲染层，这样它们各司其职，降低工作的耦合性。
由于12.29日放假前还剩 两门课设答辩和一门考试，不足之处以后再补充…
游戏资源（音频、图片、特效等）
场景和包（动画。渲染精灵和控制器等）
游戏脚本（ui、runtime等）
……太多了，只选择了部分作为展示
在gizmos目录下，可以找到对应按钮隐藏摄像机，这样处理场景的时候会舒服很多
clone都放上会有些杂乱，都删掉，只放了一个背景图
开始按钮（玩家通过点击开始按钮，进入新的一局游戏）
重玩按钮（玩家可以及时返回开始界面进行相应操作）
时钟（显示游戏剩余时间，一局游戏初始化时间是60s）
计分板（显示当前游戏得分）
普通甜品（甜甜圈、糖果、起司…至少同时有3个在同一排或同一列时，可以消除）
特殊甜品（一定条件下会触发2种特殊甜品道具，一种是带有左右晃动特效的甜品，可以消除一整排的甜品；另一种是带有上下晃动特效的甜品，可以消除一整列的甜品）
积分面板（游戏时间结束后，会用类似飞跃的动画效果产生得分界面窗口，逐渐变大显示，最终定格。点击重玩立即开始下一局游戏，叉掉返回开始界面）
小虾选用的是unity个人版，采用的是unity一个较新的版本-2021.1.16，这里建议小伙伴们下载和教程相同版本的，不然真的会有可能遇到卡点消耗心情哈。
可以和我一样在unity hub里面安装，hub感觉挺好用的。
但是每次重启后都要手动激活许可证，这是真的挺烦的。
小虾在这里主要介绍部分核心代码实现，想知道其他部分实现的小伙伴在下方留言，我再添加~
