Ore not spawning

First, you need to do a class that implements IWorldGenerator, for example i use this (it also show you how to generate a metada blocks and flowers! :) )

public class WorldGenMinableMW implements IWorldGenerator {

@Override
public void generate(Random random, int chunkX, int chunkZ, World world,
		IChunkProvider chunkGenerator, IChunkProvider chunkProvider) {

	switch(world.provider.getDimensionId()) {
		case 0:
			generateOverworld(random, world, chunkX*16, chunkZ*16);
			break;
		default:
			generateOverworld(random, world, chunkX*16, chunkZ*16);
	}

}

private void generateOverworld(Random random, World world, int x, int z) {
	addOres(MWBlocks.ruby_ore, world, random, x, z, 4, 5, 0, 16);
	addMetaOres(MWMetadataBlocks.marble.getStateFromMeta(0), world, random, x, z, 6, 15, 0, 30);
	addMetaOres(MWMetadataBlocks.marble.getStateFromMeta(1), world, random, x, z, 6, 15, 0, 30);

	for(int i = 0; i < 2; i++)
	{
		int randPosX = x + random.nextInt(16);
		int randPosY = random.nextInt(250);
		int randPosZ = z + random.nextInt(16);
		(new WorldGenFlowers((BlockFlower)MWBlocks.blue_flower, BlockFlower.EnumFlowerType.DANDELION)).generate(world, random, new BlockPos(randPosX, randPosY, randPosZ));
	}

}

private void addOres(Block block, World world, Random random, int blockXpos, int blockZpos, int MaxVein, int spawnChance, int minY, int maxY) {

	WorldGenMinable minable = new WorldGenMinable(block.getDefaultState(), random.nextInt(MaxVein));
	for (int i = 0; i < spawnChance; i++) {
		int posX = blockXpos + random.nextInt(16);
		int posZ = blockZpos + random.nextInt(16);
		int posY = minY + random.nextInt(maxY - minY);
		minable.generate(world, random, new BlockPos(posX, posY, posZ));
	}

}

private void addMetaOres(IBlockState block, World world, Random random, int blockXpos, int blockZpos, int MaxVein, int spawnChance, int minY, int maxY) {

	WorldGenMinable minable = new WorldGenMinable(block, random.nextInt(MaxVein));
	for (int i = 0; i < spawnChance; i++) {
		int posX = blockXpos + random.nextInt(16);
		int posZ = blockZpos + random.nextInt(16);
		int posY = minY + random.nextInt(maxY - minY);
		minable.generate(world, random, new BlockPos(posX, posY, posZ));
	}

}
}

 

Then you need to register that class as a world generator by doing this in the init event of your main mod class (or in a sub class called by that method)

GameRegistry.registerWorldGenerator(new WorldGenMinableMW(), 1);

 

After this you're fine and your ores should generate as well :)

Don't blame me if i always ask for your help. I just want to learn to be better :)

When you "go to Minecraft", are you starting a new world, or are you entering an existing one? Generation only occurs when you visit a virgin chunk. Previously generated chunks will not be changed by new mods with new ore generators.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

    • They were already updated, and just to double check I even did a cleanup and fresh update from that same page. I'm quite sure drivers are not the problem here. 
    • i tried downloading the drivers but it says no AMD graphics hardware has been detected    
    • Update your AMD/ATI drivers - get the drivers from their website - do not update via system  
    • As the title says i keep on crashing on forge 1.20.1 even without any mods downloaded, i have the latest drivers (nvidia) and vanilla minecraft works perfectly fine for me logs: https://pastebin.com/5UR01yG9
    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
