I haven't really done much Lua programming in the last 5 months, but I realised on my calculator yesterday there was a program I had been making, most likely in late 2012, fiddling with lines and curves. It is called Transport Chooser atm. I think I was unsure with what to do with it at the time, and also unsure with what to do it now or what I was intending to use it for. Still it is worth sharing, even though it is extremely simple.
Basically Transport allows you to choose different types of tiles/tracks, that are straight lines, curves, intersections and the like. You can currently cycle through the different tracks using the number keys and move the track position, but you can't currently place it. Most likely would have to create an array for that, and haven't really programmed with arrays yet. That's pretty much it.
Thanks, and I hope to share more new and improved Lua creations soon.
