I have a mob, but his / her loot table isn't working

Loot table class:

package com.Egietje.degeweldigemod.mobs;

import java.util.Set;

import net.minecraft.world.storage.loot.LootTableList;

import com.Egietje.degeweldigemod.Reference;
import com.google.common.collect.Sets;

import net.minecraft.util.ResourceLocation;

public class LootTables extends LootTableList {
public static final ResourceLocation ENTITIES_CHEESE_COW = register("cheese_cow");

private static ResourceLocation register(String id) {
        return register(new ResourceLocation(Reference.MODID, id));
    }
}

Loot table json:

{
{
"pools":
	[
		{
			"rolls":1,
			"entries":
			[
				{
					"type": "item",
					"name":"dgm:cheese",
					"weight":1,
					"functions":
					[
						{
							"function":"set_count",
							"count":

							"conditions":
							[
								{
									"condition":"entity_properties",
									"entity":"this",

						}
					]
				},

								}
							]
						}
					]
				}
			]
		}
	]
}
}

Eclipse console:

It looks to me like you have an extra set of curly braces around everything.

Try removing 1 set from the top/bottom and see if that helps.

 

This is the loot json for a mob I made when I was tinkering around with stuff, and it worked:

{
    "pools": [
        {
            "rolls": {
                "min": 1,
                "max": 2
            },
            "entries": [
                {
                    "type": "item",
                    "name": "minecraft:feather",
                    "weight": 1,
                    "functions": [
                        {
                            "function": "minecraft:set_count",
                            "count": {
                                "min": 1,
                                "max": 2
                            }
                        }
                    ]
                }
            ]
        }
    ]
}

/bin/assets/dgm/loot_tables/cheese_cow.json
com.google.gson.JsonParseException: Loot Table "dgm:cheese_cow" Missing `name` entry for pool #0

 

That's the error, but I honestly don't know where you went wrong.

My loot table is in assets\newmod\loot_tables\entities, called "DeathJaw.json".

I never extended the LootTable class, I just have this line in a basic class that I planned to use for storing all my loot table registrations:

public static final ResourceLocation ENTITIES_DEATHJAW = LootTableList.register(new ResourceLocation("newmod","entities/DeathJaw"));

 

The only thing I can think to give a try based on what I see is try changing dgm:cheese to dgm:cheese_cow in your loot table json.

*edit: but that doesn't even make sense, since name as far as I can tell is what you want to drop. What is the name of your loot table json, and where is it located?

I honestly have no idea; my advice would be to trim down your loot table so that it only drops 1 simple item, then slowly build up from there.

 

Also, where you have set_count, I have "minecraft:set_count", not sure if that makes a difference or not, but might be worth a try if it keeps giving you trouble.

Didn't help

 

Did you try trimming down your loot table to make it simple, to see if it works with just dropping 1 single simple item? For example, try using the loot table I posted that just drops a feather or 2. If that works, start changing 1 small thing at a time and testing.

Forge requires non-vanilla loot tables to provide a 

"name"

entry for each loot pool. You can see a working loot table here.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
