Hi all, I'm still trying to get pbLua running on my brick. I've installed the LuaEclipse plugin which allows me to write (pb)Lua files in Eclipse with a decent editor support and written some programs. Yet, I still have absolutely no clue how to (...)

Thank you for your well commented adaptation. I'm still experiencing the same problem even though the values for the different variables as shown by 'watch the brick' check out. The problem is in a different place. I wrongly assumed wait 'ticks' and (...) (19 years ago, 26-Feb-07, to lugnet.robotics)

I've written some explanation on using constants in NXT-G implmentation VIs to optimize program size during compilation. You can read it here: (URL) Ziv NXTasy.org (19 years ago, 26-Feb-07, to lugnet.robotics.nxt)

Thanks. I thought setting maxlight before the 'if' statement would be enough, but moving it closer to the front (before the 'while' statement') did the trick. The bit after the while loop still gives me pain though. I've changed it a bit to be able (...) (19 years ago, 25-Feb-07, to lugnet.robotics)

(...) Looks like you're setting maxlight = SENSOR_2, then testing if (SENSOR_2 > maxlight), which will rarely (if ever) be true, because the value of SENSOR_2 is unlikely to change in such a short time. I think the first maxlight = SENSOR_2 (...) (19 years ago, 25-Feb-07, to lugnet.robotics)

Thanks for the reply. I see I overlooked something significant there. Going over it all again I think I don't need 'light' Also, the parse errors are due to my omitting the ; at the end of each statement I've also discovered that I should put some (...) (19 years ago, 25-Feb-07, to lugnet.robotics)

I'm very glad to know you got it working again. Incidently, the '1.02' I was talking about isn't the version number on NXT-G itself, but on the USB driver it uses. If you haven't updated that, you can still occassionally get locking into 'clicking (...) (19 years ago, 25-Feb-07, to lugnet.robotics.nxt)
