I actually figured it out!

Theres actually a better way to do this, by calling the setDefaultBlock function in GenerationSettings @Override public ChunkGenerator<?> createChunkGenerator(World world) { OverworldGenSettings settings = new OverworldGenSettings(); settings.setDefaultBlock(Blocks.GRANITE.getDefaultState()); return new OverworldChunkGenerator(world, new ModBiomeProvider(), settings) ; }

I created a new class that extends the OverWorldGenSetttings, and override the function to get the block state. Heres the code my world type where I use my custom Gen Settings that extend OverWorldGenSettings public class ModWorldType extends WorldType { public ModWorldType() { super("modworld_type"); } @Override public ChunkGenerator<?> createChunkGenerator(World world) { ModGenSettings settings = new ModGenSettings(); SingleBiomeProviderSettings single = new SingleBiomeProviderSettings(world.getWorldInfo()); return new OverworldChunkGenerator(world, new ModBiomeProvider(), settings); } } Here is my Custom Gen Settings Class that extends OverWorldGenSettings. public class ModGenSettings extends OverworldGenSettings { private final int field_202212_j = 4; private final int field_202213_k = 4; private final int field_202214_l = -1; private final int field_202215_m = 63; @Override public BlockState getDefaultBlock() { return Blocks.BLACK_STAINED_GLASS.getDefaultState(); } public int getBiomeSize() { return 4; } public int getRiverSize() { return 4; } public int getBiomeId() { return -1; } public int getBedrockFloorHeight() { return 0; } } (My formatting sucks because I've been messing around with a lot of things)

So I have created a world type that currently spawns my own custom biome and I also found a way to override stone as the block type, and I can set the world to generate and block that I wish. Structures like mineshafts spawn in this world because I have them added in the biome, however caves won't be generated. I think this is because my block isn't set as a carvable type of block which are found in the WorldCarver class. I'm not sure how I would set my Custom block to be carved for caves.

Thanks, I forgot to change my eclipse to run on Java 8, so that was causing the issue!

Hello, I just started creating a mod and minecraft crashes when launching through Eclipse. However, the game loads fine if I type gradlew runClient through command line. (It even loads my 1 item) Here is the crash report: ---- Minecraft Crash Report ---- // Don't do that.
