Yeah, very glad to get replied.
I think one of the simplest of the solutions for the train jumping system is that, always rounding the distance to integers, and a min value to help voiding some boundry cases. If someone put coal into the motovitive, and ramp next to the station, the train might jump a very short distance. This is not very easy to calculate. It needs experience.
Another issue I found was that, if the train is long enough, such as 5 or more, and it accelerates slowly, it gets to the ramp not at it's max speed. In this case, the cargoes or motovatives in the front jump shorter, while the post parts jump longer. In some cases, the head is safe while the tail blasts.
When I tested the jumping pad for train, I couldn't even manage to get it to work. Train crashes with the pads all the time.
I think the usage of the jumping train, would probably limited to the intersections. So I said a fixed distance would be nice. But if this is prepared for something alike the roller coaster, ok, it's rides, not logistics.
Ok, let me think, if this mod is nod designed to be a part of the logistics, but something makes the game a purely funny. I have a lot ideas in this aspect.
But, I'm in China. I'll come back and write to you tomorrow.
Have a nice day.
