About this Mod
Format
Use this tool to generate NBT areas or JSON advancement areas.
Examples of areas
NBT: [x=0,y=0,z=0,dx=0,dy=0,dz=0]
JSON: "position":{"x": {"min":-529,"max":4},"y":{"min":3,"max":106},"z":{"min":3,"max":112}}
This makes the pain-stacking time it takes to write all the numbers down a lot easier.
