LUA weapons

How do I make my script know which weapons are available in the player's character?

I want to try to enable the old 1.09.4 feature (was that version?) where you could get the automatic ring and the rail ring to fire automatic firing rail rings, but with the actual weapons.

Looking at the useable structures post from Monster's Lua documentation thread(You should bookmark this, it's your best friend, seriously), the information you're looking for is most likely in ringweapons, from the player_t structure.

To make sense of what's in there, download the source code(see download zip, on the right) and do a search for ringweapons using Windows from within the src folder, making sure to have it search for text inside of files. That should point you in the right direction.
