I'm trying to apply effects to the emerald armor but it doesn't work, I read that the onArmorTick() method doesn't work anymore, but I tried with inventoryTick, onInventoryTick and onArmorTick but they don't apply the effect either, I don't know if I'm writing it wrong, so I need help to fix it.

This is the code in question:

public class ModArmorItem extends ArmorItem{

    private static final Map<ArmorMaterial, MobEffectInstance> MATERIAL_TO_EFFECT_MAP =
        (new ImmutableMap.Builder<ArmorMaterial, MobEffectInstance>())
            .put(ModArmorMaterials.EMERALD, new MobEffectInstance(
                MobEffects.HERO_OF_THE_VILLAGE,
                200, 
                1,
                false, 
                false, 
                true))
                .build();
    
    public ModArmorItem(ArmorMaterial pMaterial, Type pType, Properties pProperties) {
        super(pMaterial, pType, pProperties);
    }
    
    @Override
    public void onArmorTick(ItemStack stack, Level world, Player player){
        if (!world.isClientSide()) {
            if (hasFullSuitOfArmorOn(player)) {
                evaluateArmorEffects(player);
            }
        }
    }

    private void evaluateArmorEffects(Player player) {
        for (Map.Entry<ArmorMaterial,MobEffectInstance> entry : MATERIAL_TO_EFFECT_MAP.entrySet()){
            ArmorMaterial mapArmorMaterial = entry.getKey();
            MobEffectInstance mapStatusEffect = entry.getValue();

            if (hasCorrectArmorOn(mapArmorMaterial, player)) {
                addStatusEffectForMaterial(player, mapArmorMaterial, mapStatusEffect);
            }
        }
    }

    private void addStatusEffectForMaterial(Player player, ArmorMaterial mapArmorMaterial, MobEffectInstance mapStatusEffect) {
        boolean hasPlayerEffect = player.hasEffect(mapStatusEffect.getEffect());

        if (hasCorrectArmorOn(mapArmorMaterial, player) && !hasPlayerEffect) {
            player.addEffect(new MobEffectInstance(mapStatusEffect));
        }
    }

    private boolean hasCorrectArmorOn(ArmorMaterial material, Player player) {
        for (ItemStack armorStack : player.getInventory().armor){
            if (!(armorStack.getItem() instanceof ArmorItem)) {
                return false;
            }
        }

        ArmorItem helmet = ((ArmorItem)player.getInventory().getArmor(3).getItem());
        ArmorItem brestplace = ((ArmorItem)player.getInventory().getArmor(2).getItem());
        ArmorItem leggins = ((ArmorItem)player.getInventory().getArmor(1).getItem());
        ArmorItem boots = ((ArmorItem)player.getInventory().getArmor(0).getItem());

        return helmet.getMaterial() == material && brestplace.getMaterial() == material && leggins.getMaterial() == material && boots.getMaterial() == material;
    }

    private boolean hasFullSuitOfArmorOn(Player player){
        ItemStack helmet = player.getInventory().getArmor(3);
        ItemStack breastplace = player.getInventory().getArmor(2);
        ItemStack leggins = player.getInventory().getArmor(1);
        ItemStack boots = player.getInventory().getArmor(0);

        return !helmet.isEmpty() && !breastplace.isEmpty() && !leggins.isEmpty() && boots.isEmpty();
    }

}

And here is the armor
 

public static final RegistryObject<Item> EMERALD_HELMET = ITEMS.register(
    "emerald_helmet", 
        () -> new ModArmorItem(ModArmorMaterials.EMERALD, ArmorItem.Type.HELMET, new Item.Properties())
    );
    public static final RegistryObject<Item> EMERALD_CHESTPLATE = ITEMS.register(
    "emerald_chestplate", 
        () -> new ModArmorItem(ModArmorMaterials.EMERALD, ArmorItem.Type.CHESTPLATE, new Item.Properties())
    );
    public static final RegistryObject<Item> EMERALD_LEGGINS = ITEMS.register(
    "emerald_leggins", 
        () -> new ModArmorItem(ModArmorMaterials.EMERALD, ArmorItem.Type.LEGGINGS, new Item.Properties())
    );
    public static final RegistryObject<Item> EMERALD_BOOTS = ITEMS.register(
    "emerald_boots", 
        () -> new ModArmorItem(ModArmorMaterials.EMERALD, ArmorItem.Type.BOOTS, new Item.Properties())
    );

I hope you can help me. Thanks.

Fixed

On the one off the last lines of code you have put && boots.isEmpty()

Instead of && !boots.isEmpty()

is that a typo?
