Today's update includes one of the most important features of any subway simulator: the correct behavior of trains on slopes. We can't say it hasn't been a thing at all, but that system had many cons and wasn't quite suited for use on metro trains which move on splines.
How it works: every bogie tracks the spline and its checkpoints, so we can easily take that data to obtain our values of height and distance between these checkpoints. These values are being processed through a formula, and so we get our slope angle. After that, we just calculate the average slope for all bogies - it's the slope angle for the whole train. This value gets multiplied by a special coefficient so that we can get influence on train acceleration. We just have to sum this with acceleration from controller.
Also, we'd like to mention that acceleration time and stopping distances are very close to table values.
Meanwhile, we're continuing to fix bugs to begin working on a new scenario soon!
