I'm fiddling about tryign to integrate a lua interpreter into a groupAI dll, but I realise all I knwo about lua I learnt in the last hour ro two. SO please post anythign of use here.

I know nothing of lua. All I know when it comes to interpreted languages right now is python (which isn't much faster than Java).

And I do know there is a lua <> python bridge.

LUA (loo-ah) is an interpreted AND a compiled language. Yes, it can be both.

There's something called LUA Bind that's Object-based LUA, very snazzy.

afaik basic python is one of the slowest interpreted languages around.

good idea though, it would be good to support basically any other language to allow more people to work on an AI

Python is entirely interpreted though. Such slowness is expected if you have to parse all of the tokens again when you load the program up again. When using compiled python files (which python now uses by default now), you get quite a performance boost. Lua is still a better choice for game scripting, because its a lot lighter weight than python is.

The fact of the matter is that all interpreted languages are slow, so your best bet is just going with the one that is the fastest. Impliment it so that it isn't consulted every single cpu cycle and you are in luck. =)

BF2 uses Python...

That is cool....

I like python...

I think python is more like it's own language. LUA looks like a ripoff of C -language, which is hard to learn.

Whereas Python is exceptionally easy to learn...

Yes, I'm also a Python fan.

I still hate "self". I hate typing that in....I really do.

BF2 also has the worst engine backend I've ever seen in a game. It ran twice as worse as Doom 3 while struggling to get graphics that rivalled Unreal... just Unreal. As in Unreal I. Come on, I ran Doom 3 at medium settings at 800x600 and HL2 at high across the board, except water, with 2xAA at 1024x768, and those games are around a year old already! BF2 has no excuse for such a shitty engine.

C++ isn't hard to learn.

And what the hell is twice as worse?

Perhaps your eysesight is failing you, but BF2 graphics arefar better than Unreal

BitTorrent, Google... just some more notable users of Python.

still, a number of apps using python doesn't mean it's fast enough for a game like spring.

Its important to know what it was doing, rather than that it was just doing something.

Whoa, I love Python, but don't use it in-game for scripting the units or AI.

No, Lua has absolutely nothing to do with C.

Lua has the advantage of being lighter and faster than Python, but is less powerful.
Another lightweight language which can be nearly as fast as Lua and is slightly better equipped while retaining its lightness is Squirrel .

Very true. I think that Spring is (much) more CPU intensive than the average game, and I don't believe that's because of lack of optimization.

About the way it is pronounced, you can think of it as this:
Let's put a little bit!

This way, the translation of letters into sounds can be thought of as other similar translations we do in english.
