Also, your link to Zeblote's roller coaster parts links to "https://www.mediafire.com/?undefined", I think you can see why that's not much help.
Edit: I forgot to mention, what's wrong with using the default forwards, backwards, and brake keys? I'm already low on directional keys that make sense.
The link should be fixed now.
As for the second thing, I think it's better to give people the functionality they are most likely to want than the functionality that is harder to code and may cause some people to complain.
This. It took me forever to figure out exactly what the guide pieces do, and I still can't get a turn working correctly. The guide bricks' shapes make no sense.
The Guide Bricks for corners are the shape that is easiest to work with. Since it is impossible to have any kind of "cornery" brick without getting some kind of BLB professional involved, this is the next best thing.
I look forward to your tutorial.
Yes, I'll just add it to my incredibly long list of things I need to do...
Hey Chris, could you contact me over Steam? We've been working on rebooting Halloweenfest for 2014, and I updated the Trains mod. Now whenever I load up the map a very large portion of the train bricks are missing. We can't rebuild the rollercoasters.
This is probably because the previous version of Halloweenfest used the ALPHA version of the mod. Since then, track peices have been moved, renamed, added, removed and all manner of other things. You're probably going to have to do some rebuilding work, so I'm sorry. I can offer help if you need me to.
