i am trying to make a diamond junction rail connect to all the rails around it. i have been picking though BlockBaseRailLogic and can't seem to come up with a way to trick it into connecting to more then 2 rails. i know it has been done before by other mods, but can't figure out how.

Umm, if it connects into all 4 directions, does it need Logic at all then? Its just a cross, right? It doesn't need to change, so you shouldn't need to use Rail logic at all.

 

the problem is that it doesn't connect to all 4 directions, it will only connect to 2, i want it to connect to all 4.

the cart already moves over it the way i want it to, the problem is the rails next to it are not connecting. i would add a screen shot showing the problem, but i keep getting an error. 

 

edit: if you place the junction and then put a track north and south of it then place two more east and west of it. the ones on the east and west sides will not connect to the junction.

I don't think that is possible. Vanilla rails can only connect to 2 sides, so you'd need to have it like this:

  ||

==XX==

  ||

  ||

where XX is your cross. That should make the rails "connect" even though they are not.

 

i was hopping there was something in the code that i missed since making players use that work around feels kind of iffy, but thanks for trying to help.

I haven't messed with rails, but this should be possible.  Afterall, Railcraft did it.
