- Do not create over-limit.
- We are checking for any nodes of the mapblocks of the sector being beyond the limit.
- A sector is a vertical column of mapblocks, so sectorpos is like a 2D blockpos.
-
- At the negative limit we are checking for
- block minimum nodepos < -mapgenlimit.
- At the positive limit we are checking for
- block maximum nodepos > mapgenlimit.
-
- Block minimum nodepos = blockpos * mapblocksize.
- Block maximum nodepos = (blockpos + 1) * mapblocksize - 1.
