for only having one biome in the Type its very simple :

Quote

    @Override
    public BiomeProvider getBiomeProvider(World world) {
        return new BiomeProviderSingle(Modbiome.WASTELAND);
    }

 

i tried now that:

 

public BiomeProvider getBiomeProvider(World world) {
        BiomeProvider bp = WorldType.DEFAULT.getBiomeProvider(world);
        bp.allowedBiomes.clear();
        bp.allowedBiomes.add(Modbiome.DRYEDLAKE);

        bp.allowedBiomes.add(Modbiome.WASTELAND);
        return bp;
    }

 

    public BiomeProvider getBiomeProvider(World world) {

        BiomeProvider bp =new BiomeProviderSingle(Modbiome.WASTELAND);
        bp.allowedBiomes.add(Modbiome.DRYEDLAKE);
        return bp;
    }

i tried that but the upper one will generate normal biomes and the lower one only my wasteland biome, it seems that the list dont affect the biomes that will spawn, how to change the biomeprovider to spawn both biomes?

Create your own BiomeProvider instance.

I dont know what to override in there everything i tried dont worked

I created a genLayerCustom for multiple biomes

public GenLayerWasteland(long p_i45560_1_, GenLayer p_i45560_3_, WorldType p_i45560_4_, ChunkGeneratorSettings p_i45560_5_)
    {
        super(p_i45560_1_);
        this.parent = p_i45560_3_;

        for(BiomeType type : BiomeType.values()) {
            int desertIdx = type.ordinal();
            
            if (biomes[desertIdx] == null) biomes[desertIdx] = new ArrayList<BiomeEntry>();
            biomes[desertIdx].add(new BiomeEntry(Modbiome.DRYEDLAKE, 10));
            biomes[desertIdx].add(new BiomeEntry(Modbiome.WASTELAND, 30));
        }
        
        if (p_i45560_4_ == WorldType.DEFAULT_1_1) {
            this.settings = null;
        }
        else {
            this.settings = p_i45560_5_;
        }
    }
