Hi,
I never coded lua. I wonder if it is possible to script a mini-game when i enter in a room like a tic tac toe.
Thanks
Yes this is possible, there are probably various ways of doing it depending on how you want the gameplay of the mini-game.
This will be a non-trivial script, so the prerequisite is to know Lua. I recommend the Programming in Lua book: http://www.lua.org/pil/contents.html
