blocks not droping


Recommended Posts

I am making a mod and am adding blocks, but when I break them, they don't drop anything! I don't know what's wrong.

The code of the block:

Spoiler

package flamepoint1544.flames_additions.block;

 

import net.minecraft.world.level.block.state.BlockState;

import net.minecraft.world.level.block.state.properties.NoteBlockInstrument;

import net.minecraft.world.level.block.state.BlockBehaviour;

import net.minecraft.world.level.block.SoundType;

import net.minecraft.world.level.block.Block;

import net.minecraft.world.level.BlockGetter;

 

import net.minecraft.core.BlockPos;

 

public class UltimatiumOreBlock extends Block {

    public UltimatiumOreBlock() {

        super(BlockBehaviour.Properties.of().instrument(NoteBlockInstrument.BASEDRUM).sound(SoundType.STONE).strength(3f, 10f).requiresCorrectToolForDrops().speedFactor(1.1f).jumpFactor(1.1f).hasPostProcess((bs, br, bp) -> true)

                .emissiveRendering((bs, br, bp) -> true));

    }


 

    @Override

    public int getLightBlock(BlockState state, BlockGetter worldIn, BlockPos pos) {

        return 6;

    }

 

}

Your block needs a loot table. Either write one manually as a datapack json file (see the vanilla wiki) or use data generation (recommended):

https://docs.minecraftforge.net/en/1.20.x/datagen/server/loottables/

Datagen explanation:

Spoiler


e.g. this class is the main provider and contains all your subproviders:

... extends LootTableProvider {

public ModLootTableProvider(PackOutput output) {
	super(output, Set.of(), List.of(
		new SubProviderEntry(ModBlockLoot::new, LootContextParamSets.BLOCK)
	));
}

And this one does the loot for blocks specifically

public class ModBlockLoot extends BlockLootSubProvider {
    
    protected ModBlockLoot() {
        super(Set.of(), FeatureFlags.REGISTRY.allFlags());
    }

    @Override
    protected Iterable<Block> getKnownBlocks() {
        return ModBlocks.BLOCKS // Get all registered entries
                .stream() // Stream the wrapped objects
                .flatMap(RegistryObject::stream) // Get the object if available
                ::iterator; // Create the iterable
    }

    @Override
    protected void generate() {
      	// some basic examples
        this.dropSelf(ModBlocks.SOMETHING_LIKE_DIRT.get());
        this.dropWhenSilkTouch(ModBlocks.SOMETHING_LIKE_GLASS.get());
      	// some other kinds use this format, see vanilla examples
        this.add(ModBlocks.SOMETHING_LIKE_VINES.get(), BlockLootSubProvider::createShearsOnlyDrop);
    }

Then add your provider:

in main mod constructor or something {
	...
	modEventBus.addListener(this::gatherData);
	...
}


public void gatherData(final GatherDataEvent event) {
        DataGenerator generator = event.getGenerator();
        PackOutput out = generator.getPackOutput();
  
  		generator.addProvider(event.includeServer(), new ModLootTableProvider(out));
 		// other providers can go here too.
    }

When you use the runData run configuration it'll generate the json files for you.
