[1.15.2] Armor Set and Potion Effects


Recommended Posts


I'm making a mod that gives the player an effecet when wears the full set, but it doesn't work while Minecraft is running.

I've tried writting onArmorTick method in my ModArmorMaterial but nothing happens, also IntelliJ doesn't allow me use @Override



package com.TitanKnight.dragonCrystals.util;

import com.TitanKnight.dragonCrystals.DragonCristalsMod;
import com.TitanKnight.dragonCrystals.armor.ModArmorMaterial;
import com.TitanKnight.dragonCrystals.blocks.*;
import com.TitanKnight.dragonCrystals.items.ItemBase;
import com.TitanKnight.dragonCrystals.tools.ModItemTier;
import net.minecraft.block.Block;
import net.minecraft.inventory.EquipmentSlotType;
import net.minecraft.item.ArmorItem;
import net.minecraft.item.Item;
import net.minecraftforge.fml.RegistryObject;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;

public class RegistryHandler {

    public static final DeferredRegister<Item> ITEMS= new DeferredRegister<>(ForgeRegistries.ITEMS, DragonCrystalsMod.MOD_ID);
    public static final DeferredRegister<Block> BLOCKS = new DeferredRegister<>(ForgeRegistries.BLOCKS, DragonCrystalsMod.MOD_ID);

    public static void init(){

    public static final RegistryObject<Item> AQUAMARINE = ITEMS.register("aquamarine", ItemBase::new);

    public static final RegistryObject<Item>AQUAMARINE_HELMET = ITEMS.register( "aquamarine_helmet", () ->
            new ArmorItem(ModArmorMaterial.AQUAMARINE, EquipmentSlotType.HEAD, new Item.Properties().group(DragonCrystalsMod.TAB)));

    public static final RegistryObject<Item>AQUAMARINE_CHESTPLATE = ITEMS.register( "aquamarine_chestplate", () ->
            new ArmorItem(ModArmorMaterial.AQUAMARINE, EquipmentSlotType.CHEST, new Item.Properties().group(DragonCrystalsMod.TAB)));

    public static final RegistryObject<Item>AQUAMARINE_LEGGINGS = ITEMS.register( "aquamarine_leggings", () ->
            new ArmorItem(ModArmorMaterial.AQUAMARINE, EquipmentSlotType.LEGS, new Item.Properties().group(DragonCrystalsMod.TAB)));

    public static final RegistryObject<Item>AQUAMARINE_BOOTS = ITEMS.register( "aquamarine_boots", () ->
            new ArmorItem(ModArmorMaterial.AQUAMARINE, EquipmentSlotType.FEET, new Item.Properties().group(DragonCrystalsMod.TAB)));

    public static final RegistryObject<Block> AQUAMARINE_ORE = BLOCKS.register("aquamarine_ore", AquamarineOre::new);
    //Blocks Items
    public static final RegistryObject<Item> AQUAMARINE_ORE_ITEM = ITEMS.register("aquamarine_ore", ()->new BlockItemBase(AQUAMARINE_ORE.get()));


This is my RegistryHandler class where I register items an blocks

import net.minecraft.util.SoundEvents;
import net.minecraft.world.World;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.api.distmarker.OnlyIn;

import java.util.function.Supplier;

public enum ModArmorMaterial implements IArmorMaterial {

    AQUAMARINE(DragonCrystalsMod.MOD_ID + ":aquamarine_armor", 25, new int[]{2, 5, 6, 2}, 18,
            SoundEvents.ITEM_ARMOR_EQUIP_GENERIC, 0.0F, () -> {
        return Ingredient.fromItems(RegistryHandler.AQUAMARINE.get());

    private static final int[] MAX_DAMAGE_ARRAY = new int[]{11, 16, 15, 13};
    private final String name;
    private final int maxDamageFactor;
    private final int[] damageReductionAmountArray;
    private final int enchantability;
    private final SoundEvent soundEvent;
    private final float toughness;
    private final Supplier<Ingredient> repairMaterial;

    ModArmorMaterial(String name, int maxDamageFactor, int[] damageReductionAmountArray, int enchantability,
                     SoundEvent soundEvent, float toughness, Supplier<Ingredient> repairMaterial) {
        this.name = name;
        this.maxDamageFactor = maxDamageFactor;
        this.damageReductionAmountArray = damageReductionAmountArray;
        this.enchantability = enchantability;
        this.soundEvent = soundEvent;
        this.toughness = toughness;
        this.repairMaterial = repairMaterial;

    public int getDurability(EquipmentSlotType slotIn) {
        return MAX_DAMAGE_ARRAY[slotIn.getIndex()] * this.maxDamageFactor;

    public int getDamageReductionAmount(EquipmentSlotType slotIn) {
        return this.damageReductionAmountArray[slotIn.getIndex()];

    public int getEnchantability() {
        return this.enchantability;

    public SoundEvent getSoundEvent() {
        return this.soundEvent;

    public Ingredient getRepairMaterial() {
        return this.repairMaterial.get();

    public String getName() {
        return this.name;

    public float getToughness() {
        return this.toughness;


This is myModArmorMaterial


	 public void onArmorTick(ItemStack stack, World world, PlayerEntity player) {
        if (player.getItemStackFromSlot(EquipmentSlotType.HEAD).getItem() == RegistryHandler.AQUAMARINE_HELMET.get()
            && player.getItemStackFromSlot(EquipmentSlotType.CHEST).getItem() == RegistryHandler.AQUAMARINE_CHESTPLATE.get() &&
            player.getItemStackFromSlot(EquipmentSlotType.LEGS).getItem() == RegistryHandler.AQUAMARINE_LEGGINGS.get() &&
            player.getItemStackFromSlot(EquipmentSlotType.FEET).getItem() == RegistryHandler.AQUAMARINE_BOOTS.get()
        ) {
            player.addPotionEffect(new EffectInstance(Effects.SPEED));

When I use #Override, it says 'Anotations are not allowed'


public class ItemBase extends Item {
    public ItemBase() {
        super(new Item.Properties().group(DragonCrystalsMod.TAB));
	public void onArmorTick(World world, PlayerEntity player, ItemStack itemStack){
        if(player.getItemStackFromSlot(EquipmentSlotType.HEAD).getItem() == RegistryHandler.AQUAMARINE_HELMET.get()
                && player.getItemStackFromSlot(EquipmentSlotType.CHEST).getItem() == RegistryHandler.AQUAMARINE_CHESTPLATE.get() &&
                player.getItemStackFromSlot(EquipmentSlotType.LEGS).getItem() == RegistryHandler.AQUAMARINE_LEGGINGS.get() &&
                player.getItemStackFromSlot(EquipmentSlotType.FEET).getItem() == RegistryHandler.AQUAMARINE_BOOTS.get()
        ) {
            //player.addPotionEffect(new EffectInstance(Effects.SPEED));

This is my Item class

It does not allow you to override the method because it is different from its parent method.

it should be 

onArmorTick(ItemStack stack, World world, PlayerEntity player)


onArmorTick(World world, PlayerEntity player, ItemStack itemStack)

not sure if it's changed in 1.15.2+ tho, but you can always find it in Item class.

Btw you have an extra curly braces here

	public void onArmorTick(World world, PlayerEntity player, ItemStack itemStack){
        if(player.getItemStackFromSlot(EquipmentSlotType.HEAD).getItem() == RegistryHandler.AQUAMARINE_HELMET.get()
                && player.getItemStackFromSlot(EquipmentSlotType.CHEST).getItem() == RegistryHandler.AQUAMARINE_CHESTPLATE.get() &&
                player.getItemStackFromSlot(EquipmentSlotType.LEGS).getItem() == RegistryHandler.AQUAMARINE_LEGGINGS.get() &&
                player.getItemStackFromSlot(EquipmentSlotType.FEET).getItem() == RegistryHandler.AQUAMARINE_BOOTS.get()
        ) {   <---------------------
            //player.addPotionEffect(new EffectInstance(Effects.SPEED));

Thanks for your help, that constructor was part of the problem.

I also create a new CustomArmor class to replace ArmorItem class in my register


public class CustomArmorAquamarine extends ArmorItem {

    public CustomArmorAquamarine(IArmorMaterial materialIn, EquipmentSlotType slot, Properties builder) {
        super(materialIn, slot, builder);

    public void onArmorTick(ItemStack itemstack, World world, PlayerEntity player) {
	//check armor
	player.addPotionEffect(new EffectInstance(Effects.SPEED, 300, 0));

    • Hm. I did try adding that in the user_jvm_args.txt but I get this:  Error: Could not find or load main class C:Program FilesJavajdk-17.0.9binjavaw.exe Caused by: java.lang.ClassNotFoundException: C:Program FilesJavajdk-17.0.9binjavaw.exe Press any key to continue . . . I tried both with "\jdk-17\" (as it appears in the program files) as well as "\jdk-17.0.9\"  No luck. am I placing it in the wrong file? Could the second part be incorrect? 
    • Hello, I am trying to make a drowned transform into a custom mod I made (called Hot Drowned) when it goes through a magma bubble column. I already have the mob fully working in game, but the code for the transformation is giving me trouble. Since I can't edit the drowned code, I tried to make it check on Living Tick Event for a drowned that is doing the ticking and check its position from there in relation to a magma block but its not working. My code is below, thank you in advance. @SubscribeEvent(priority = EventPriority.HIGHEST) public void entityJoinWorld(LivingEvent.LivingTickEvent event, ServerLevel pServerLevel) { System.out.println("Entity Ticked"); Entity entity = event.getEntity(); if (entity.isAlive() && entity instanceof Drowned) { Drowned drowned = (Drowned) entity; BlockPos bPos = BlockPos.of(drowned.blockPosition().get(Direction.Axis.Y)); BlockState bPosBlock = pServerLevel.getBlockState(bPos); int dHieght = bPos.getY(); if (bPosBlock == Blocks.WATER.defaultBlockState() || bPosBlock == Blocks.MAGMA_BLOCK.defaultBlockState()){ if (bPosBlock == Blocks.MAGMA_BLOCK.defaultBlockState()){ ModEntities.HOT_DROWN.get().spawn(pServerLevel, BlockPos.of(drowned.blockPosition().get(Direction.Axis.Y)), NATURAL); }else { for (int x = dHieght + 64; x > 0; x--) { bPos = BlockPos.of(bPos.below().get(Direction.Axis.Y)); bPosBlock = pServerLevel.getBlockState(bPos); System.out.println(bPosBlock); if (bPosBlock == Blocks.MAGMA_BLOCK.defaultBlockState()) { ModEntities.HOT_DROWN.get().spawn(pServerLevel, BlockPos.of(drowned.blockPosition().get(Direction.Axis.Y)), NATURAL); } else { return; } } } } } } }
