HI, when I set MAX_DAMAGE_FACTOR greater than 1 this error comes, for example I set the Max damage factor to 2 - 

Error loading mods

1 error has occurred during loading

Forge Mod (forge_mod) encountered an error during the common_setup event phase 

java.lang.ArrayIndexOutOfBoundsException: Index 6 out of bounds for length 4

 

whereas if I set the MAX_DAMAGE_FACTOR 3 this error comes - 

Forge Mod (forge_mod) encountered an error during the common_setup event phase 

java.lang.ArrayIndexOutOfBoundsException: Index 9 out of bounds for length 4

 

My Code - 

package com.anirudh.forgemod.armor;

public enum ModArmorMaterial implements ArmorMaterial {

    RUBY(ForgeMod.MOD_ID + ":ruby",2, new int[] { 2, 5, 6, 2}, 999999999,

    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;

    ModArmorMaterial(String name, int maxDamageFactor, int[] damageReductionAmountArray, int enchantability,

        this.name = name;
        this.maxDamageFactor = maxDamageFactor;
        this.damageReductionAmountArray = damageReductionAmountArray;
        this.enchantability = enchantability;
        this.soundEvent = soundEvent;
        this.toughness = toughness;
        this.repairMaterial = repairMaterial;
    }

    @Override
    public int getDurabilityForSlot(EquipmentSlot equipmentSlot) {
        return MAX_DAMAGE_ARRAY[equipmentSlot.getIndex() * this.maxDamageFactor];
    }

    @Override
    public int getDefenseForSlot(EquipmentSlot equipmentSlot)
     {
        return this.damageReductionAmountArray[equipmentSlot.getIndex()];

        return this.repairMaterial.get();
    }

   @OnlyIn(Dist.CLIENT)

    @Override
    public String getName() {
        return this.name;
    }

    @Override
    public float getToughness() {
        return this.toughness;
    }

    @Override
    public float getKnockbackResistance() {
        return 0;
    }
}

 

The thing is I can set it to 1 but then the Armor will be very weak

I don't think there is an error in this part of the text, or is it? I don't get it, Can you please explain.

what is 3 * 7? < that's wrong

But how does return MAX_DAMAGE_ARRAY[equipmentSlot.getIndex() * this.maxDamageFactor]; effect the length of the array?

MAX_DAMAGE_ARRAY is 4 elements long, you want to get element 6 that is why you get ArrayIndexOutOfBoundsException

ok thans

It doesn't say higher than 3, but says higher than 4

I know some basics, but I don't know some of them For eg. final

Ok thanks for all the info

Ok thanks for all the info

How do I fix the problem? Should I add more Items to the Array?

or is there something like .push?

I didn't I watched this tutorial - 

 

ok, one last question

In one of the lines I wrote

    RUBY(ForgeMod.MOD_ID + ":ruby",1, new int[] { 2, 5, 6, 2, }, 999999999,
            SoundEvents.AMBIENT_CAVE, 1000.0F, () ->{ return Ingredient.of(RegistryHandler.RUBY.get()).group(); });

The error is - Cannot resolve method 'group' in Ingredient, I think the name has changed but to which name?

In registry Handler - 

    public static final RegistryObject<ArmorItem> RUBY_HELMET = ITEMS.register("ruby_helmet", () ->
            new ArmorItem(ModArmorMaterial.RUBY, EquipmentSlot.HEAD, new Item.Properties().group()));

the same error as the previous one

The method is tab but while registering which tab the tutorial says  .group(ItemGroup), but their is no ItemGroup, so is their a name for that as well?

    @SubscribeEvent
    public static void generateOres(FMLLoadCompleteEvent event){
        for (Biome biome : ForgeRegistries.BIOMES){

            if (biome.getBiomeCategory() == Biome.BiomeCategory.NETHER){

            } else if (biome.getBiomeCategory() == Biome.BiomeCategory.THEEND){

            } else {
