如果我想自己做一个block,该怎么做呢 #3

  1. 用json定义该block，参考built-in blocks (/Source/JsonBlocks/ 目录下)；
  2. 如果使用C#，解释该Block的行为(code interpreter)，参考built-in blocks (/Source/Script/CodeDB/CSharp/Interpreters/ 目录下)； 3.如果使用Lua，为该Block生成Lua代码(code generator)，参考built-in blocks (/Source/Script/CodeDB/Lua/Generators/ 目录下)； 4.如果是特殊的block（带有变形功能），需要提供可供编辑变形的UI。（这一步比较麻烦，可能你并不需要）

json定义和code interpreter都写了，但是会报错，不知道哪边细节没做好。

从这个log里我看不出问题出在哪里。 方便把你的case给我一下，我试一下。 或者你自己也可以debug源代码看一下？

问题出在你没有给新加的block定义一个“类别”，如果你是直接加在built-in的类别里面，比如说couroutine，那么blockType需要加上couroutine的前缀用来区分“类别”，也用于UI的的类别显示，例如 coroutine_find_obj. 如果你要自己新加一个类别，那么需要在 UBlocklyData/Toolboxs/Configs/toolbox_default.json中加一个。 抱歉，文档欠缺，我后面补全，谢谢～
