Again I come back to see absolutely nothing useful contributed to this thread. That's fine. All I asked was for those who wanted to help me come into contact with me, and they've done so, and I am being helped now.
somewhat.
As for progress, things seem to be going about as smooth as I had hoped. The game is still a buggy mess, the slope collisions still suck (mostly because I have no idea what the proper way to do them would be), I totally rewrote the majority of the Lua-handling code at this point with more changes on the way, to make things easier script-side in the long run...
This is taking priority over rewriting the network code as well, and then after that I still have to make the inventory menu and the map system and etc. And at some point, add scripting stuff for allowing custom HUDs, background movement types, dialogs, and so on... Still a really long ways to go.
As far as teaching you to script objects in Lua... Well, I can only do what I can, unfortunately.
All the documentation for what extra resources you have in scripting objects for AGL is kept in Generic.lua (global.lua in the SVN and next release...) Otherwise, it's just Lua, a convoluted scripting branch off languages like BASIC and C.
I don't know how to teach someone to program in general, but at least I've written out a listing of what everything does and can be used for, as well as provided ample example in writing the code for so many of the objects in the game already.
This is all I can do to help you aside from answering every question you have and helping you make what objects you want to, for which you need to come in contact with me in the IRC channels or my own message board, provided specifically for such.
