篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了unity 一个拼图demo（七巧板）和一个切割demo—2相关的知识，希望对你有一定的参考价值。
前面好久之前只是讲到了七巧板的和切割的原理，这节就讲一下2个demo的主游戏逻辑的代码。先说一下切割demo的逻辑代码，首先我们的准备一个题库，这个题库最好做成Excel表，然后最好直接转成ScriptObject序列化的文件，如果大家有这方面的需要我也可以提供代码，还有一种简单的就是直接由Excel转json，然后通过json读数据这样显然跟家复杂并且比第一种方法慢些。题目的格式得自己去定了，就是Excel表的内容得自己定，例如可能存的是多边形每个角的坐标位置，还有怎么分的问题。贴一下MainSliceGame这个类：
