Hi Ralph,
I have some more questions about pbLua...
Is the NXT-Lua-API public available ?
My idea is to use your pbLua-functions at my PC running Lua-Interpreter,
replaceing low level stuff with own functions...
This allows me to write and runs programs local (NXTpbLuaSim).
The next step is to connect this NXTpbLuaSim via luasocket to a virtual
3D-Simulation like ct-Sim
(http://www.heise.de/ct/ftp/projekte/ct-bot/ct-sim.shtml)...
Some german guys started this project last year and we had much fun with
simulating simple AVR-based robots.
What do you think about this idea ?
I just need you Lua-Tables 8-)
Thanx for some notes
Bye
Christian
