ImmuneOne and s.bat, please continue your discussion via PM, this thread was made to find out if the community was intrested in trying Lua, not if it was easy to do your own scripting language etc etc.
Emme I would love to see you do this. The commuinty could use this in sources. I use a lua npc engine build right in my source. My engine is only in fact really like 80 percent lua becasue the main part of the engine is threaded and built under c#. I would love to see this be released good luck.
I'm pretty sure Emme knows what to do already.
Anyway, I think it is interesting, it won't make your server any slower, and it is efficient.
However, I'm not sure if its beneficial to add it, since it might take a while.
