Example 1 with SharedSeedRandom

use of net.minecraft.util.SharedSeedRandom in project NetherEx by LogicTechCorp.

the class CaveChunkGenerator method decorate.

@Override
public void decorate(WorldGenRegion region) {
    int chunkX = region.getMainChunkX();
    int chunkZ = region.getMainChunkZ();
    int posX = chunkX * 16;
    int posZ = chunkZ * 16;
    BlockPos pos = new BlockPos(posX, 0, posZ);
    BiomeData biomeData = NetherEx.BIOME_DATA_MANAGER.getBiomeData(this.getBiome(region.getBiomeManager(), pos.add(8, 8, 8)));
    SharedSeedRandom random = new SharedSeedRandom();
    long decorationSeed = random.setDecorationSeed(region.getSeed(), posX, posZ);
    if (biomeData != BiomeData.EMPTY) {
        for (GenerationStage.Decoration stage : GenerationStage.Decoration.values()) {
            biomeData.decorate(stage, this, region, decorationSeed, random, pos);
        }
    }
