Which coaster is hardest for you to build with? in General Discussion Posted July 24, 2016 · Edited July 24, 2016 by X7123M3-256 · Report reply Just now, DaKoasterNerd said: That is completely true. I find that the Air Powered RC trains were originally designed to go upside down. I have used an Air-Powered train on Twister Track - made the loop with no graphic issues at all. They weren't designed to go upside down and neither were the real ones. However, an interesting quirk of the game is that any ride that has sprites for vertical slopes must also have sprites for vertical loops. So those sprites were rendered but apparently never intended to be used. An even more extreme example is the reverse freefall coaster - it has sprites for turns, sloped turns, steep turns, verticals and loops, but it can't do any turns or loops. It has hundreds of sprites and only uses a small fraction of them. I don't know why they bothered rendering these sprites instead of just leaving them blank, but those images have to be present in the file in order to have the vertical slopes. Just now, DaKoasterNerd said: The Heartline Twister coaster is a bit difficult to work with (limited elements available). For the park I am building at the moment, I have merged it with LIM coaster track so it can turn and do immelmann type elements (for example). TOGO pipeline coasters don't turn. They're also pipeline coasters - they wouldn't be able to run on traditional coaster track, hence the unusual tubular track design. All but one is a stock layout, though there is one with a dive loop in place of one of the reversing sections. They're limited in game because they're limited in real life, but they're even more limited in game than they are IRL. The real ones have a vertical elevator lift to start the ride - since this can't be done in game and you don't even have a vertical slope with which to fake it, you'd have to use a track merge just to make a realistic layout. I also like building 4D coasters - one of the most interesting designs to work with for certain. However, the real life layouts are very large, all very similar, and difficult to do well in game, which doesn't give a lot of flexibility, so I usually build mine based on the Arrow concept layouts instead of the designs actually found in parks today. They're smaller, more practical, and have more diverse layouts so you can do things like put a raven turn straight off the lift hill. I wish one had been built.
