Embedding Lua in C++ #26 - Creating Native Objects Using Run Time Type Information

Показать описание

The stub project for these videos is available here.

How to embed Lua into a C++ application and interface with the Lua C API.
To follow along you should be familiar with how to code in C++, some knowledge of the Lua scripting langage itself is preferable as this is not a scripting language tutorial.
The tutorial is on Windows and using CMake and Visual Studio, but you could build this code on pretty much any platform.

I've found that I can take what you've taught and VERY easily integrate it with Qt's QMetaObject implementation. Great stuff! Very helpful :)

Another topic of discussion would be passing arguments to the constructor.

You have an extra *lua_pushvalue* in your binding loop. Right before you create "new". *lua_setfield* doesn't pop the table off the stack. I needed to delete that otherwise I get some memory bugs. Idk 100% if that is the cause of my bugs, but removing that fixed the duplicate tables on the stack and my bug is gone (for now).

I only noticed an issue after I bound about 11 classes to it then started an empty script.
