Hi,

i am playing around with custom mobs. The beast will not drop what i want him to drop. I've copied the original loot table from a zombie, but nothing. Even no error on the console.

 

My Entity class

Create your loot-tables resource location like this:
 

final ResourceLocation lootTable = new ResourceLocation(yourMODID, "loot_table_name_without_modid_folder_and_fileending");

 

Register your loot-tables resource location in preInit like this:

LootTableList.register(yourLootTableResourceLocation);

 

Then pass it along in your entity as before.

Clarification.

I did this way before. Was like

public static final ResourceLocation deathLootTable = new ResourceLocation(TheWizardMod.MODID, "loot_table/entities/weird_zombie");

 

As result got a warning. With ending the warning will not come, but still no drops.

[Server thread/WARN]: Couldn't find resource table thewizardmod:loot_table/entities/weird_zombie

 

I've also change from EntityMob to EntityZombie. All that chances is that they now burning in sunlight.

 

Mean time i've registered an onEntityDrop event in my event handlers. That will do the job. But the loot table still not working.

 

You shouldn't have to handle the event for your own custom mob. Events are mostly for changing behavior of vanilla mobs.

 

Your error is that the resource location is still not pointing to the proper file. I think that is because I don't think you need the loot_table/ in your resource location -- it already knows to look there. Instead maybe you should have:

 

public static final ResourceLocation deathLootTable = new ResourceLocation(TheWizardMod.MODID, "entities/weird_zombie");

Also not working. No warnings in the console, but still no droppings from the loot table.

And i've got a second problem. How can i display the spawn egg in my own creative tab? Because it's not an item, as it's registered with

RenderingRegistry.registerEntityRenderingHandler(EntityWeirdZombie.class, RenderWeirdZombie.FACTORY);

Can't use setCreativeTab. It allways will be only in the misc tab.

Oh wait. it's registered here like this :

EntityRegistry.registerModEntity(EntityWeirdZombie.class, "WeirdZombie", id++, TheWizardMod.instance, 64, 3, true, 0x996600, 0x00ff00);

Are you calling LootTable.register() in your pre-init event handler?

I did

 

package thewizardmod.entity;

import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityList;
import net.minecraft.entity.EnumCreatureType;
import net.minecraft.init.Biomes;
import net.minecraft.world.storage.loot.LootTableList;
import net.minecraftforge.fml.common.registry.EntityRegistry;
import thewizardmod.TheWizardMod;


public class StartupCommon
{
	private static int entityID = 0;

	public static void preInitCommon()
	{
        int id = 1;
        EntityRegistry.registerModEntity(EntityWeirdZombie.class, "WeirdZombie", id++, TheWizardMod.instance, 64, 3, true, 0x996600, 0xff00ff);
//        EntityRegistry.addSpawn(EntityWeirdZombie.class, 100, 3, 5, EnumCreatureType.MONSTER, Biomes.PLAINS, Biomes.ICE_PLAINS);

        LootTableList.register(EntityWeirdZombie.deathLootTable);
	}

	public static void initCommon()
	{
}

	public static void postInitCommon()
	{
	}
	

}

 

It's registered. I've commend out the spawn, because i only spawn them in my custom dimension.
