Getting Radius of chunks

[Draco18s]

For the life of me, I can't figure out why you should even care. If you check "this chunk" and then the 3 neighbor chunks at +X, +Z, and +X+Z (all of which are guaranteed to already exist, even if they have not yet been populated) then you should be fine.

 

If they have been populated already, you don't cause further population. If the current chunk caused anything to appear in them, you find it. If they haven't been populated, you don't cause further population (because vanilla already expects cross-chunk-boundary placements to occur in this direction and not cascade population). If the current chunk caused anything to appear in them, you find it. If that chunk's own population would place it, but it hasn't populated yet, you don't need to care, because it will fire its own population event.

 

ALL OTHER CHUNKS ARE IRRELEVANT
