Hey, I was wondering if there is a mod out there where it shows you the speed the coaster car would be going at a certain track piece? This would be very helpful if you are trying to make smoother rides. It could reduce G-Force and increase your excitement rating a lot. It would also be easier to know when to add brakes or if it is okay to add a barrel roll for example. If there isn't a mod out there like this then someone should make one. Another good idea is to have a track piece turn red if there is a lot of G-Force while going through that track piece.
I think there's a way you can do that with the same way that you can measure it through the course of the ride. Unfortunately I don't have photos of that but I know it exists in game.
While the coaster is running, click on the little graph icon on the side of the rides control panel. It will let you monitor speed, g-forces and other things in realtime as the coaster is running while opened or while testing or building the ride.
It can let you see where speeds and g-forces peak. If you are running multiple trains it will only monitor the first train that leaves the station. When it falls off an unfinished track the graph will stop until you restart the test mode.
