or there are other ways to handle this?

I guess this is the function that handles drop count in diomand_ore json file, but I could not find where to fix my own ore(now it only drop one) { "function": "minecraft:apply_bonus", "enchantment": "minecraft:fortune", "formula": "minecraft:ore_drops" }

I made an ore in my mod. When I copied the loot table json file from diomand_ore in vanilla, I found it only drop one item, not like other vanilla ores. I compared other json file of vanilla ores(diomand_ore, coal_ore and so on), they have no difference except the name of loot. Where can I handle the drop count of ores?

It works. Thank U

I created a custom wood in the game, but it can not burn down. I used flint and steel, I used lava, but the custom wood just burned a while, then the fire ceased, the wood remained. I add vanilla tag(logs, logs that burn) to my wood, and the material of my wood block is Wood, but it still didn't disappear. I wonder how could my wood behave like the vanilla ones?

Thank you! It helped me a lot.

How could I display HP at living entity head? I want to display a HP bar at entity head, kind of a floating rectangle. But I have no idea what method I could use or what class I should concern. Could some experienced modders give me some guidance? Please🙏🙏🙏

I wander how to use World.addParticle to add custom particle effect, or is there any other ways to add? Or is there anything wrong with my particle effect?

These are my particle effect classes, they are all copied from a tutorial. public class Juan1ParticalType extends ParticleType { public Juan1ParticalType() { super(false, Juan1ParticalData.DESERIALIZER); } @Override public Codec<Juan1ParticalData> func_230522_e_() { return Codec.unit(new Juan1ParticalData(new Vector3d(0, 0, 0), new Color(0xF63900), 0)); } } public class Juan1ParticalData implements IParticleData { private final Vector3d speed; private final Color color; private final float diameter; public static final IDeserializer<Juan1ParticalData> DESERIALIZER = new IDeserializer<Juan1ParticalData>() { @Override public Juan1ParticalData deserialize(ParticleType<Juan1ParticalData> particleTypeIn, StringReader reader) throws CommandSyntaxException { final int MIN_COLOUR = 0; final int MAX_COLOUR = 255;reader.expect(' '); double speedX = reader.readDouble(); reader.expect(' '); double speedY = reader.readDouble(); reader.expect(' '); double speedZ = reader.readDouble(); reader.expect(' '); int red = MathHelper.clamp(reader.readInt(), MIN_COLOUR, MAX_COLOUR); reader.expect(' '); int green = MathHelper.clamp(reader.readInt(), MIN_COLOUR, MAX_COLOUR); reader.expect(' '); int blue = MathHelper.clamp(reader.readInt(), MIN_COLOUR, MAX_COLOUR);reader.expect(' '); int alpha = MathHelper.clamp(reader.readInt(), 1, MAX_COLOUR);reader.expect(' '); float diameter = reader.readFloat(); return new Juan1ParticalData(new Vector3d(speedX, speedY, speedZ), new Color(red, green, blue, alpha), diameter); } @Override public Juan1ParticalData read(ParticleType<Juan1ParticalData> particleTypeIn, PacketBuffer buffer) { final int MIN_COLOUR = 0; final int MAX_COLOUR = 255; double speedX = buffer.readDouble(); double speedY = buffer.readDouble(); double speedZ = buffer.readDouble(); int red = MathHelper.clamp(buffer.readInt(), MIN_COLOUR, MAX_COLOUR); int green = MathHelper.clamp(buffer.readInt(), MIN_COLOUR, MAX_COLOUR); int blue = MathHelper.clamp(buffer.readInt(), MIN_COLOUR, MAX_COLOUR); int alpha = MathHelper.clamp(buffer.readInt(), 1, MAX_COLOUR); float diameter = buffer.readFloat(); return new Juan1ParticalData(new Vector3d(speedX, speedY, speedZ), new Color(red, green, blue, alpha), diameter); } }; public Juan1ParticalData(Vector3d speed, Color color, float diameter) { this.speed = speed; this.color = color; this.diameter = diameter; } @Override public ParticleType<?> getType() { return Utils.ParticleRegistry.JUAN_1_PARTICLE.get(); } @Override public void write(PacketBuffer buffer) { buffer.writeDouble(this.speed.x); buffer.writeDouble(this.speed.y); buffer.writeDouble(this.speed.z); buffer.writeInt(this.color.getRed()); buffer.writeInt(this.color.getGreen()); buffer.writeInt(this.color.getBlue()); buffer.writeInt(this.color.getAlpha()); buffer.writeFloat(this.diameter); } @Override public String getParameters() { return String.format(Locale.ROOT, "%s %.2f %i %i %i %i %.2d %.2d %.2d", this.getType().getRegistryName(), diameter, color.getRed(), color.getGreen(), color.getBlue(), color.getAlpha(), speed.getX(), speed.getY(), speed.getZ()); } public Vector3d getSpeed() { return speed; } public Color getColor() { return color; } public float getDiameter() { return diameter; } } public class Juan1Particle extends SpriteTexturedParticle { public Juan1Particle(ClientWorld world, double x, double y, double z, Vector3d speed, Color color, float diameter) { super(world, x, y, z, speed.x, speed.y, speed.z); maxAge = 100; setColor(color.getRed() / 255F,color.getGreen() / 255F,color.getBlue() / 255); this.setAlphaF(color.getAlpha()); final float PARTICLE_SCALE_FOR_ONE_METER = 0.1F; particleScale = PARTICLE_SCALE_FOR_ONE_METER * diameter; this.canCollide = true; } @Override public IParticleRenderType getRenderType(){ return IParticleRenderType.PARTICLE_SHEET_TRANSLUCENT; } } public class Juan1ParticleFactory implements IParticleFactory<Juan1ParticalData> { private final IAnimatedSprite sprites; public Juan1ParticleFactory(IAnimatedSprite sprite) { this.sprites = sprite; } @Override public Particle makeParticle(Juan1ParticalData typeIn, ClientWorld worldIn, double x, double y, double z, double xSpeed, double ySpeed, double zSpeed) { Juan1Particle particle = new Juan1Particle(worldIn, x, y, z, typeIn.getSpeed(), typeIn.getColor(), typeIn.getDiameter()); particle.selectSpriteWithAge(sprites); return particle; } }

This is where I want to call the addParticle() method, it is in the livingTick() in an entity. But it shows no particle effect. @Override public void livingTick() { double x = rand.nextGaussian() * 0.02D; double y = rand.nextGaussian() * 0.02D; double z = rand.nextGaussian() * 0.02D; double px = this.getPosX() + 4.0D * rand.nextDouble() - 2.0D; double py = this.getPosY() + rand.nextDouble() - 0.5D; double pz = this.getPosZ() + 4.0D * rand.nextDouble() - 2.0D; world.addParticle(new Juan1ParticalData(new Vector3d(x, y, z), new Color(0xae6be2), 0), px, py, pz, x, y, z); } When I change "new Juan1ParticalData(new Vector3d(x, y, z), new Color(0xae6be2), 0)" to "ParticleTypes.DRAGON_BREATH" , the particle effects appeared.

I made a particle effect of my own, and I can only display the particle effect in the game through the command : /particle mymod:juan1particle 0 0 0 0 0 255 100 3. When I want add the particle through World.addParticle(IParticleData particleData, double x, double y, double z, double xSpeed, double ySpeed, double zSpeed), it does not show at all. But when I change the particleData Parameter from my particledata's instance to those in the ParticleTypes in the vanilla, It works without problem. So it seems that only my particle effect can't be added into the game, but those in the vanilla can be added.

OK, Thanks for your advice.

The URL I saw in the 1.16 tutorial to get the latest Mapping is now unavailable. My mapping now is : mappings channel: 'snapshot', version: '20210309-1.16.5' Could someone tell me a way to get the latest Mapping, or tell me the latest Mapping?
