Hello,
i'd like it if you (or I/me -> continue reading) could replace all that instanceOf checks of minecart regarding BlockRailBase by an instanceOf check to an interface that could be extracted from the class.
Reason for that is that it would be nice if you could create a new rail block that doesn't have to extend BlockRailBase but indeed alows spawning of minecarts on it.
If you can give me an easy link to "how to contribute to mcforge" (setup etc) i'd be grateful and if it's ok i'd change that myself since it's not that hard extracting an interface from a class using eclipse
