Module ore_veinifier 

Ore vein generation during terrain fill.

Matches vanilla’s OreVeinifier. Evaluates the three vein density functions (vein_toggle, vein_ridged, vein_gap) per solid block to decide whether to replace stone with copper/iron ore, raw ore blocks, or filler (granite/tuff).

Structs

OreVeinifier

Ore vein generator. Holds cached block state IDs and the positional random splitter used for per-block randomness.

VeinType 🔒

A vein type with its Y range and block variants.

Constants

CHANCE_OF_RAW_ORE_BLOCK 🔒

Probability of placing a raw ore block instead of ore.

EDGE_ROUNDOFF_BEGIN 🔒

Within this many blocks of the vein type’s Y boundary, the threshold tightens.

MAX_EDGE_ROUNDOFF 🔒

Maximum tightening applied at the very edge of the Y range.

MAX_RICHNESS 🔒

Maximum richness (at veininess >= 0.6).

MIN_RICHNESS 🔒

Minimum richness (at veininess = 0.4).

SKIP_ORE_IF_GAP_BELOW 🔒

Vein gap noise must be above this to place ore (otherwise filler).

VEININESS_THRESHOLD 🔒

Veininess magnitude must exceed this (after edge roundoff) to place any vein block.

VEIN_SOLIDNESS 🔒

Probability of NOT skipping a vein block (nextFloat must be <= this).
