I just bought official minecraft and I'm in a middle of migrating my modpack from 1.7.10 to 1.12.2.
I'm trying to find a mod that will add an Enviromine-like physics to the 1.12.2. I found the SchopCraft mod that ports thurst/temperature/sanity, but not the physics.
The BlockPhysics mod doesn't port yet.
So kinda dunno, should I write it by myself or not.
P.S. What about achievements mods?
I too am looking for this, but I have not found any yet. If you can or want to write it yourself I'd be very grateful!
