Subject: Ore distribution: Deeper iron, diamond and mese block, tune gold (#2107)
X-Git-Tag: 5.0.0~87
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=8d8f2f79d02ff4cd2a03b67ae19ab23b9a566c41;p=oweals%2Fminetest_game.git

Ore distribution: Deeper iron, diamond and mese block, tune gold (#2107)

Iron at y = 0 was far too easy to find.
Adjust gold lower region to be twice the depth of highest level, like
all other ores.
Diamond at y = -500 was too easy to progress to.
Make diamond and mese block deeper to create a depth progression from
mese crystal to diamond, to reflect tool progression.
This all creates a satisfying 2^n depth progression, with lower regions
being at twice the depth of highest levels.
