Hello my name is Lifeofsenpai and I have a quick question. I will start by saying I have a small amount of knowledge on how to code in java and have wrote small mods before, however I have no idea how to do this. For the mod-pack I am currently working on, I want to include galacticraft's low gravity and no air in my super flat world. I am only looking for a addon or way to have an empty world with low gravity and no air. If anyone has any answers to this question please tell me. Thank you for your time.
