How can I use C++ code in Lua?

[jime]

Im tring to make a mod and I hope I can use my previous code.

Factorio mods only support writing them in Lua. So the answer is: you can't.

Even if you could, I don't see how it would be useful to recycle old code. You need to use a lot of factorio specific features. What exactly are you trying to do/reuse?

If you don't want to reinvent the wheel, take a look at some of the existing mod libraries, like Factorio Library . You can use any of them as a dependency for your mod, and use the functions they maintain.
