[SOLVED] Start modding

[Def Daemon]

Hello

I'm a total noob when it comes to modding, but I know some basics (can create blocks, items, ores, loottables etc), but now I want to create a custom weapon. It is a simple "wooden stake" to kill vampires with it. This weapon can be used once and will be removed after a single hit. Attack speed, harvesting level etc do not apply here.

My first question: Should I base this weapon on the Item class or should I write a class that inherits from the SwordItem class?

My second question: Where can I check if the entity I'm attacking is a vampire?

 

Thnx

Most checks in Minecraft rely on instanceof to check if something is a sword so you should extend SwordItem.

To check if the attacked entity is a vampire you can also use instanceof. You can override hurtEnemy in your item class to do something when it is used for attacking.

Okay, I will start with that...

I did some research on the Internet and came up with the code below. The only problem is that "wooden_stake" is not registered (Java Nullpointer error can't find "wooden_stake). What am I missing?

    public Main()
    {
        instance = this;
        IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus();
        modEventBus.addListener(this::setup);
        modEventBus.addListener(this::clientSetup);
        BlockList.BLOCKS.register(modEventBus);
        ItemList.ITEMS.register(modEventBus);
        EntityList.ENTITIES.register(modEventBus);
        MinecraftForge.EVENT_BUS.addListener(EventPriority.HIGH, OreGeneration::generatesOres);
        MinecraftForge.EVENT_BUS.register(this);
    }

items/WoodenStake class

public class WoodenStake extends SwordItem
{
    public WoodenStake(IItemTier tier, int attackDamageIn, float attackSpeedIn, Properties builder) {
        super(tier, attackDamageIn, attackSpeedIn, builder);
    }
}

list/ToolMaterialList

public enum ToolMaterialList implements IItemTier
{
    wooden_stake(1.0f,0.0f,1,0, 1000000, ItemList.WOODEN_STAKE.get());

    private float attackDamage, efficiency;
    private int durability, harvestLevel, enchantability;
    private Item repairMaterial;

    private ToolMaterialList(float attackDamage, float efficiency, int durability, int harvestLevel, int enchantability, Item repairMaterial)
    {
        this.attackDamage = attackDamage;
        this.efficiency = efficiency;
        this.enchantability = enchantability;
        this.durability = durability;
        this.harvestLevel = harvestLevel;
        this.repairMaterial = repairMaterial;
    }

    @Override
    public int getUses() {
        return this.durability;
    }

    @Override
    public float getSpeed() {
        return this.efficiency;
    }

    @Override
    public float getAttackDamageBonus() {
        return this.attackDamage;
    }

    @Override
    public int getLevel() {
        return this.harvestLevel;
    }

    @Override
    public int getEnchantmentValue() {
        return this.enchantability;
    }

    @Override
    public Ingredient getRepairIngredient() {
        return Ingredient.of(this.repairMaterial);
    }
}

lists/ItemList

public class ItemList {

    public static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, Main.MOD_ID);
    public static final RegistryObject<Item> WOODEN_STAKE = ITEMS.register("wooden_stake", () -> new WoodenStake(ToolMaterialList.wooden_stake, 0, 6.0f, new Item.Properties().tab(ItemGroup.TAB_COMBAT)));
}

I would highly suggest making a github repo for sharing your code, it makes it much easier to share, just a link instead of a wall of text.

Had this link bookmarked from ages ago (yeah I don't clean out my bookmarks) when someone asked me about it: https://readwrite.com/2013/09/30/understanding-github-a-journey-for-beginners-part-1/

You cannot access your items here yet, the registration has not happened yet. Store the supplier instead of the item.

You also haven't done this:
