Hello, I am building my first mod (whoo!), and am trying to implement world generation. I am trying to generate my ores in the overworld, however my IDE can't define BASE_STONE_OVERWORLD BASE_STONE_OVERWORLD, BASE_STONE_NETHER, neither works. Help!
overworldOres.add(register("copper_ore", Feature.ORE.withConfiguration(new OreFeatureConfig(
OreFeatureConfig.FillerBlockType.BASE_STONE_OVERWORLD, RegistryHandler.COPPER_ORE.get().getDefaultState(), 4)) //Vein Size
.range(64).square() //Spawn height start
.func_242731_b(64))); //Chunk spawn frequency
