Item not generating with Global Loot Modifiers.

I made a Global Loot Modifier that doesn't seem to be working. I've probably messed up in the FireSwordInChest.java file. Here is FireSwordInChest.java:

package com.juder.elementalswords.event.loot;

import com.google.gson.JsonObject;
import net.minecraft.resources.ResourceLocation;
import net.minecraft.util.GsonHelper;
import net.minecraft.world.item.Item;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.level.storage.loot.LootContext;
import net.minecraft.world.level.storage.loot.predicates.LootItemCondition;
import net.minecraftforge.common.loot.GlobalLootModifierSerializer;
import net.minecraftforge.common.loot.LootModifier;
import net.minecraftforge.registries.ForgeRegistries;

import javax.annotation.Nonnull;
import java.util.List;

public class FireSwordFromChestAdditionModifier extends LootModifier {
    private final Item addition;

    protected FireSwordFromChestAdditionModifier(LootItemCondition[] conditionsIn, Item addition) {
        super(conditionsIn);
        this.addition = addition;
    }

    @Nonnull
    @Override
    protected List<ItemStack> doApply(List<ItemStack> generatedLoot, LootContext context) {
        System.out.println("YO!");
        generatedLoot.add(new ItemStack(addition, 1));
        return generatedLoot;
    }

    public static class Serializer extends GlobalLootModifierSerializer<FireSwordFromChestAdditionModifier> {

        @Override
        public FireSwordFromChestAdditionModifier read(ResourceLocation name, JsonObject object, LootItemCondition[] conditionsIn) {
            Item addition = ForgeRegistries.ITEMS.getValue(new ResourceLocation(GsonHelper.getAsString(object, "addition")));
            return new FireSwordFromChestAdditionModifier(conditionsIn, addition);
        }

        @Override
        public JsonObject write(FireSwordFromChestAdditionModifier instance) {
            JsonObject json = makeConditions(instance.conditions);
            json.addProperty("addition", ForgeRegistries.ITEMS.getKey(instance.addition).toString());
            return json;
        }
    }
}

Any help would be appreciated.

Please don't put anything from 1.16.5, 1.12.2, 1.14, 1.15, 1.0, or anything not 1.18.x or 1.19.x!

Nope, that class looks fine.
Did you register the serializer? Did you add it to the forge/global_loot_modifiers.json list?

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

If you are using 1.19 the GLM doesn't use a serializer anymore.

It uses Codecs.

You can see some examples in the forge tests:

https://github.com/MinecraftForge/MinecraftForge/blob/1.19.x/src/test/java/net/minecraftforge/debug/gameplay/loot/GlobalLootModifiersTest.java

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.
