Hello,

 

I'm in the process of updating my 1.14.4 mod to 1.15.1.

 

It has an ore generation class that handles interesting custom ores into biomes.

 

Here is the existing class.

//My version being ported from 1.14.4 to 1.15.1

public class OreGenerator
{
    public static void setupOregen()
    {
        for(Biome biome : ForgeRegistries.BIOMES)
        {
            if(GeneralModConfig.BORNITE_ORE_GENERATION.get())
                biome.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(NATURAL_STONE, BlockList.bornite_ore.getDefaultState(), GeneralModConfig.BORNITE_ORE_SIZE.get().intValue()), COUNT_RANGE, new CountRangeConfig(GeneralModConfig.BORNITE_ORE_CHANCE.get(), GeneralModConfig.BORNITE_ORE_MIN_HEIGHT.get(), GeneralModConfig.BORNITE_ORE_MIN_HEIGHT.get(), GeneralModConfig.BORNITE_ORE_MAX_HEIGHT.get())));
 
            if(GeneralModConfig.CASSITERITE_ORE_GENERATION.get())
                biome.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(NATURAL_STONE, BlockList.cassiterite_ore.getDefaultState(), GeneralModConfig.CASSITERITE_ORE_SIZE.get().intValue()), COUNT_RANGE, new CountRangeConfig(GeneralModConfig.CASSITERITE_ORE_CHANCE.get(), GeneralModConfig.CASSITERITE_ORE_MIN_HEIGHT.get(), GeneralModConfig.CASSITERITE_ORE_MIN_HEIGHT.get(), GeneralModConfig.CASSITERITE_ORE_MAX_HEIGHT.get())));
            
            if(GeneralModConfig.WOLFRAMITE_ORE_GENERATION.get())
                biome.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(NATURAL_STONE, BlockList.wolframite_ore.getDefaultState(), GeneralModConfig.WOLFRAMITE_ORE_SIZE.get().intValue()), COUNT_RANGE, new CountRangeConfig(GeneralModConfig.WOLFRAMITE_ORE_CHANCE.get(), GeneralModConfig.WOLFRAMITE_ORE_MIN_HEIGHT.get(), GeneralModConfig.WOLFRAMITE_ORE_MIN_HEIGHT.get(), GeneralModConfig.WOLFRAMITE_ORE_MAX_HEIGHT.get())));
        }
    }
}

 

In Eclipse with 1.15.1, the createDecoratedFeature highlights with the text of "The method createDecoratedFeature(Feature<OreFeatureConfig>, OreFeatureConfig, Placement<CountRangeConfig>, CountRangeConfig) is undefined for the type Biome".

 

So, I traced the usage difference from 1.14.4 to 1.15.1

 

1.14.4 version

public static void addOres(Biome biomeIn) {
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, Blocks.COAL_ORE.getDefaultState(), 17), Placement.COUNT_RANGE, new CountRangeConfig(20, 0, 0, 128)));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, Blocks.IRON_ORE.getDefaultState(), 9), Placement.COUNT_RANGE, new CountRangeConfig(20, 0, 0, 64)));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, Blocks.GOLD_ORE.getDefaultState(), 9), Placement.COUNT_RANGE, new CountRangeConfig(2, 0, 0, 32)));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, Blocks.REDSTONE_ORE.getDefaultState(), 8), Placement.COUNT_RANGE, new CountRangeConfig(8, 0, 0, 16)));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, Blocks.DIAMOND_ORE.getDefaultState(), 8), Placement.COUNT_RANGE, new CountRangeConfig(1, 0, 0, 16)));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, Blocks.LAPIS_ORE.getDefaultState(), 7), Placement.COUNT_DEPTH_AVERAGE, new DepthAverageConfig(1, 16, 16)));
  }

 

1.15.1 version

  public static void addOres(Biome biomeIn) {
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Feature.ORE.func_225566_b_(new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, field_226791_az_, 17)).func_227228_a_(Placement.COUNT_RANGE.func_227446_a_(new CountRangeConfig(20, 0, 0, 128))));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Feature.ORE.func_225566_b_(new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, field_226740_aA_, 9)).func_227228_a_(Placement.COUNT_RANGE.func_227446_a_(new CountRangeConfig(20, 0, 0, 64))));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Feature.ORE.func_225566_b_(new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, field_226741_aB_, 9)).func_227228_a_(Placement.COUNT_RANGE.func_227446_a_(new CountRangeConfig(2, 0, 0, 32))));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Feature.ORE.func_225566_b_(new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, field_226742_aC_, 8)).func_227228_a_(Placement.COUNT_RANGE.func_227446_a_(new CountRangeConfig(8, 0, 0, 16))));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Feature.ORE.func_225566_b_(new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, field_226743_aD_, 8)).func_227228_a_(Placement.COUNT_RANGE.func_227446_a_(new CountRangeConfig(1, 0, 0, 16))));
     biomeIn.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Feature.ORE.func_225566_b_(new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, field_226744_aE_, 7)).func_227228_a_(Placement.COUNT_DEPTH_AVERAGE.func_227446_a_(new DepthAverageConfig(1, 16, 16))));
  }

 

I noticed the differences, but I don't understand what the "functionalists_255566_b" variable refers to in the 1.15.1 version.

 

I'm hoping someone could explain the format change.

 

Thank you in advance.

You mean the function?

Feature.ORE.func_225566_b_(...)

Its a function. Go look at what it does.

Got it, thanks. Figured it out.
