Vein & Indicator Generators

Vein Generators

Layered Vein Generator

vein.layeredVeinGenerator(generator => generator
    .buildLayerPattern(pattern => pattern
        .layer(l => l.weight(3).mat(GTMaterials.Silver).size(2, 4))
        .layer(l => l.weight(2).mat(GTMaterials.Gold).size(1, 1))
        .layer(l => l.weight(1).block(() => Block.getBlock('minecraft:oak_log')).size(1, 1))
        .layer(l => l.weight(1).state(() => Block.getBlock('minecraft:oak_planks').defaultBlockState()).size(1, 1))
    )
)

Veined Vein Generator

vein.veinedVeinGenerator(generator => generator
    .oreBlock(GTMaterials.Silver, 4) // (1)
    .rareBlock(GTMaterials.Gold, 1) // (2)
    .rareBlockChance(0.25)
    .veininessThreshold(0.1)
    .maxRichnessThreshold(0.3)
    .minRichness(0.3)
    .maxRichness(0.5)
    .edgeRoundoffBegin(10) // (3)
    .maxEdgeRoundoff(0.2) // (4)
)

1. Param 1: Either a material or block state
   Param 2: Generation weight
2. Param 1: Either a material or block state
   Param 2: Generation weight
3. Determines how much the veins become thinner towards their ends
4. Determines how much the veins become thinner towards their ends

Noise Parameters

The vein's noise parameters can be summarized as follows: - veininessThreshold defines how "sharp" the edges of the vein are.
Higher values result in more "blurry" edges. - maxRichnessThreshold defines how many ores generate inside the vein (must be >= veininessThreshold).
A higher distance between the values results in less "filled" veins. - minRichness and maxRichness allow you to limit the output of this calculation to a specific range.

The output of this calculation determines the chance for each block in the vein to generate.

Height Ranges

The height range of the generator is automatically inferred if you use heightRangeUniform() or heightRangeTriangle() in the vein definition, before setting the generator. Otherwise you need to set the height range manually:

generator.minYLevel(10)
generator.maxYLevel(90)

Dike Vein Generator

vein.dikeVeinGenerator(generator => generator
    .withBlock(GTMaterials.Silver, 3, 20, 60) // (1)
    .withBlock(GTMaterials.Gold, 1, 20, 40)
)

1. Param 1: Either a material or block state
   Param 2: Generation weight
   Param 3: Min Y Position
   Param 4: Max Y Position

Height Ranges

The height range of the generator is automatically inferred if you use heightRangeUniform() or heightRangeTriangle() in the vein definition, before setting the generator. Otherwise you need to set the height range manually:

generator.minYLevel(10)
generator.maxYLevel(90)

Standard Vein Generator

Not yet documented

vein.standardVeinGenerator(generator => /* ... */)

Geode Vein Generator

Not yet documented

vein.geodeVeinGenerator(generator => /* ... */)

Indicator Generators

Surface Rock Indicators

vein.surfaceIndicatorGenerator(indicator => indicator
    .surfaceRock(GTMaterials.Platinum) // [*] (1)
    .placement("above") // (2)
    .density(0.4)
    .radius(5)
)

1. Instead of a surface rock, you can also define any other block:
   

   // Using a block:
   indicator.block(Block.getBlock('minecraft:oak_log'))
   
   // Using a block state:
   indicator.state(Block.getBlock('minecraft:oak_log').defaultBlockState())
   

2. Valid options:
   surface generates indicators on the world's surface
   above generates indicators in the next free space above
   below generates indicators in the next free space below
   
   Default: surface
