sol2 兼容BUG - Githubissues

tyler-chang commented 7 months ago

我们项目中使用 sol2 3.2.3 作为绑定库. 在不使用 sol2 注册任何类型时. 调试一切正常. 当使用sol2注册一个类型: 如下代码: m_lua.new_usertype<CLogger>("CLogger", "debug_print", &CLogger::DebugPrint); 再进行调试时, 调试器就会崩溃. 提示以下错误:

CScript: sol: runtime error: sol: cannot call '__pairs/pairs' on type 'sol::as_container_t<CLogger>': it is not recognized as a container

注: 崩溃不会立即发生. 在点击调试器 Global 时崩溃(如下图)

我看到是 getGlobalVariable 在序列化全局变量时出错了。原因是导入的CLogger类型无法用pairs遍历。导致遍历时出错

这里的修复需要有接口能够判断是so2导入类型，并对导入类型进行序列化，也可以简单点处理对导入类型不做遍历操作。这个库我之前没用过，有空的时候我看一下

好的, 谢谢. sol2 绑定库用的人还是蛮多的. 可以适当兼容一下.
