How to generate multiple ores

Posted December 19, 201311 yr

Hi guys, I'm very new to modding, both with Minecraft and Forge, and I am having difficulty working out how to get multiple ores to generate in the overworld.

Currently, I only have one class file to generate one ore in the overworld, and it works, but I don't know if I need to have multiple generation classes or if I can get all my ore to generate from one class. Could someone please point me in the right direction of what I would need to do?

This is my my working generation class:

package Syn.Tutorial;

import java.util.Random;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import cpw.mods.fml.common.IWorldGenerator;
import cpw.mods.fml.common.IWorldGenerator;

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

	switch(world.provider.dimensionId){

	case 0 : generateSurface(world, random,chunkX*16,chunkZ*16);
	}
}

private void generateSurface(World world, Random random, int BlockX, int BlockZ) {
for(int i =0; i<10;i++){
	int Xcoord = BlockX + random.nextInt(16);
	int Zcoord = BlockZ + random.nextInt(16);
	int Ycoord = random.nextInt(50);
	(new WorldGenMinable(DivineMetals.OrichOre.blockID, 4)).generate(world, random, Xcoord, Ycoord, Zcoord);
}
}
}

Any help is greatly appreciated

You actually can generate it in your current method. I generated multiple ores in the nether like this:

package engineer.morenether.worldgen;

import java.util.Random;

public class NetherOreGen implements IWorldGenerator
{
public NetherOreGen()
{
	GameRegistry.registerWorldGenerator(this);
	// This will only work when you create this class in: @EventHandler FMLInitializationEvent
}

@Override
public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider) 
{
	if(world.provider.dimensionId == -1)
	{
		int x = chunkX * 16;
		int z = chunkZ * 16;

		this.generateCoal(world, x, z, random);

		this.generateEmerald(world, x, z, random);
	}
}

private void generateCoal(World world, int x, int z, Random r)
{	
	for(int i = 0; i < 200; i++)
	{
		int xCoord = x + r.nextInt(16);

	}
}

	}
}

private void generateLapis(World world, int x, int z, Random r)
{	
	for(int i = 0; i < 240; i++)
	{
		int xCoord = x + r.nextInt(16);
		int yCoord = r.nextInt(117) + 10;
		int zCoord = z + r.nextInt(16);

		WorldGenMinable gen = new WorldGenMinable(BlockID.NetherOre, 3, r.nextInt(, Block.netherrack.blockID);
		gen.generate(world, r, xCoord, yCoord, zCoord);
	}
}

private void generateGold(World world, int x, int z, Random r)
{	
	for(int i = 0; i < r.nextInt(140); i++)
	{
		int xCoord = x + r.nextInt(16);
		int yCoord = r.nextInt(117) + 10;
		int zCoord = z + r.nextInt(16);

		WorldGenMinable gen = new WorldGenMinable(BlockID.NetherOre, 4, r.nextInt(11), Block.netherrack.blockID);
		gen.generate(world, r, xCoord, yCoord, zCoord);
	}
}

private void generateDiamond(World world, int x, int z, Random r)
{
	for(int i = 0; i < r.nextInt(60); i++)
	{
		int xCoord = x + r.nextInt(16);
		int yCoord = r.nextInt(117) + 10;
		int zCoord = z + r.nextInt(16);

		WorldGenMinable gen = new WorldGenMinable(BlockID.NetherOre, 5, r.nextInt(7), Block.netherrack.blockID);
		gen.generate(world, r, xCoord, yCoord, zCoord);
	}
}

private void generateEmerald(World world, int x, int z, Random r)
{	
	for(int i = 0; i < r.nextInt(125); i++)
	{
		int xCoord = x + r.nextInt(16);
		int yCoord = r.nextInt(117) + 10;
		int zCoord = z + r.nextInt(16);

		WorldGenMinable gen = new WorldGenMinable(BlockID.NetherOre, 1, r.nextInt(5), Block.netherrack.blockID);
		gen.generate(world, r, xCoord, yCoord, zCoord);
	}
}
}

I am fairly new to Java and modding, so my answers are not always 100% correct. Sorry for that!

Thanks for the reply! I'll give that a try

How to add my mob to another mod's biome in 1.20.1.

You can add mob spawns using Forge's Biome Modifiers feature. I won't go into details on how to use a data generator for them, but here's a simple example:
{ "type": "forge:add_spawns", // Required "biomes": "#namespace:biome_tag", // Accepts a biome id, [list of biome ids], or #namespace:biome_tag "spawners": { "type": "namespace:entity_type", // Type of mob to spawn "weight": 100, // int, spawn weighting "minCount": 1, // int, minimum pack size "maxCount": 4 // int, maximum pack size } }This JSON file would go somewhere like this: data/modid/forge/biome_modifier/your_biome_modifier.json

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)

Help with file conversion

Many Forge users seek help with file conversions. Similarly, managing your health can benefit from structured tools like the https://wellness-app.com/calculator/fasting-calculator/ and a free intermittent fasting calculator. These tools help you plan and personalize your fasting and eating windows based on your lifestyle and goals. By entering your preferred fasting duration and meal times, you receive a tailored schedule that makes intermittent fasting easier to follow. Just as mastering file conversions improves modding success, using a fasting calculator brings clarity and structure to your health routine, supporting better results over time.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated
