Hi

I began to compile some Lua API documentation (for 0.9.14, not all functions are available at 0.9.13). It's available at http://hedgewars.railsbox.eu/Lua%20API
As it's in wiki form, anyone can contribute and improve, and I hope so will.

I think Lua makes it easy to do some cool scripted maps/missions. Possible things include capture the flag like modes, and defending targets vs. attacking them.
