nice black magic f***ery :)
I had simillar idea after seeing that famous reddit post, but didnt figure out how to actually do it :(
this was my idea .... maybe u get inspiration from it :)
- bridge-rail:
- cannot rotate - horizontal only
- has no collision box (read: collision box that will not collide with veritical/diagonal/curved rail)
- cannot be "crossed" by horizontal rail (makes no sense)
- is at least 1 waggon wide
- can be placed on odd vertical tiles (vanilla rails can be placed on even tiles) => will not connect to normal rail without ramp
2) on-off ramp: (without it bridges would be too easy to build - basically every intersection would become bridge)
- again no rotation
- has "standard" rail collision box + machine collision => cannot be crossed by another rail
- is at least 1 waggon wide
end result would look like this: (warning: mspaint job) http://i.imgur.com/Fud0dPc.png
