Perhaps in another thread, since this is about Lua? Please make it, since both AngelScript, Falcon and Chai are scripting languages that should be discussed more!

Just wondering... but I would actually like to create a thread about it, to see how many are actually using it. I'll do that.

- What I do to reference objects, is that objects inside the core engine are simply named; so if the Lua code tries to reference an object that doesn't exist on the C++ side of things, just print an error that it couldn't find "frog_prince_23". This helps with debugging a lot, much better than leaky pointers and/or segfaults because something was removed from the game engine.

This works great for games with few entities. In my case my game has over 100,000 entities, and looking them up by string would be excruciatingly slow. In cases where you have more than a handful of entities, you can use userdata for super fast access, and allow Lua to manage object lifetime with it's garbage collector.

Could you please write a tutorial on the subject  of userdata? I've embedded lua before but never seem to understand this thing so it's like an unfinished business

Hehe, I have a comprehensive Lua tutorial in the tutorials section right now. It covers userdata and metatables. It shows you how to export C++ classes to Lua in a way that makes it easy to use and extend them, plus use Lua garbage collection with C++ destructors.

BTW, mods, I demand to be levelled up, or for the tutorials section's description to be cleansed of empty promises. I've posted two tutorials and have yet to receive my accolades. [/tantrum]

Terrific! Thank you so much!
