Hi all. I have an item in the mod with durability, from which another item is crafted. Can I somehow transfer durability to a new item?

 

here is the item class code:

 

package com.zombier.slimesing.items;

import net.minecraft.world.item.CreativeModeTab;

import net.minecraft.world.item.Item;

import net.minecraft.world.item.ItemStack;

 

public class NeedlepItem extends Item {

public NeedlepItem(){

     super(new Properties()

     .tab(CreativeModeTab.TAB_TOOLS)

    .stacksTo(1) .defaultDurability(128)

    .setNoRepair() );

} 

     @Override public boolean hasContainerItem(ItemStack stack){ return true; }

     @Override public ItemStack getContainerItem(ItemStack itemStack) {

     ItemStack stack = itemStack.copy();

     stack.setDamageValue(itemStack.getDamageValue() + 1);

     return stack;

}

}

 

If I'm returning the item, don't mind it, I'll fix it. The main thing is to understand how to transfer strength to a new item. It must be damaged by the same number of units as the previous one. The idea is that I have a needle that has durability, and I have a needle with thread that should take on the same durability after crafting.

that sounds like a vanilla feature where you combine two items in crafting table. doesn't matter that it's not the same.

did you look at RepairItemRecipe class?

You need to make your own subclass of CraftingRecipe (I assume this is the crafting table?) along with a Serializer for it.

Then override Recipe.assemble() to do what you want.

 

See for example FireworkRocketRecipe.

Thank you. I will try to apply your advice, I hope I succeed.

Could you provide a link to an example? I can't find it on the internet. Sorry if my questions are stupid, I'm just learning modding.

I wrote a class, but I don't understand from which class it should be inherited.

 

Code:

public class CraftingRecipe extends RepairItemRecipe {

    public CraftingRecipe(ResourceLocation resourceLocation) {

    super(resourceLocation);

   }

}

then stop and breathe.

place a cursor on "RepairItemRecipe" identifier and press ctrl+b (or ctrl+click it). study that class until you understand it completely. do not proceed until you understand repair recipe class and firework recipe class.

Thanks for the advice. I have overridden the method. How can I initialize it in the code so that this craft will work? I understand that most likely it is somewhere in the main class, but how?

register the recipe serializer in similar manner to how you register blocks (DeferredRegister<RecipeSerializer<?>>, RegistryObject<RecipeSerializer<?>>).

Thanks a lot, you helped me a lot!
