Hey guys, sorry I hijacked the thread with a piece about sideways gravity in space stations, it wasn't really even the right place for that (but it helps me to get the ideas written down in a logical way).
Thank you @JakXLT for bringing the thread back on topic.
We have short-range teleporters so why not gravity generators, I guess. I'll talk to micdoodle8 about it. They might not be seen until GC4. But I can see the hilariousness of a gravity generator suddenly being switched off. Our freefall code would need a bit more work, I think you'd want players, mobs, items and liquids all to start floating about in mid-air when that happens.
Sure thing. Keep us posted, if you guys decide you want to add in gravity generators there are some other ways it can be done, without the use of magnets.
