I am not sure you will find a way to debug your Lua scripts directly with
the engine unless the engine itself provides some sort of debugging hooks.

Which engine are you using? Have you tried to contact them to inquire about
debugging capabilities for Lua scripts? There are a number of programs out
there for Lua to allow you to edit and run scripts, however, unless they
know how to interface with your game engine they won't be of much help.

Usually game engines that come as "black boxes", where you only have the
game engine to run itself without sources, have some sort of facility to
enter a debugging mode... or come with a special debugging version of
the engine you can run while developing. Another issue is that standalone
Lua editors will not have access to the libraries present in the game
engine, making debugging scripts externally pretty much impossible.

I would suggest trying to contact the vendor of the game engine as they
will be more in a position to help you with your debugging issues.

Good luck with your game!
