Subject: Retrieve mapblocks from the server in a sphere, not a cube
X-Git-Tag: 0.4.15~128
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e7c62edec90c476b54ea7cf7c44354f1609e4575;p=oweals%2Fminetest.git

Retrieve mapblocks from the server in a sphere, not a cube

Use unused range argument in 'isBlockInSight()' to limit mapblock sends
to a sphere of radius 'max block send distance'.
