Hi Forge Users

 

I have search for ages after a tutorial on how to get items to take damage when used in crafting recipe.

 

I know that in older versions of forge i could use CraftingHandler.

But it's been made to an event know.

 

The problem is that i cant find any tutorials on how to make it with events...

 

If anyone know how to do this please help me!

Event Class:

package dudesmods.lozmod.lozmod3.proxy;

import net.minecraft.block.Block;
import net.minecraft.item.ItemStack;
import net.minecraft.potion.Potion;
import net.minecraft.potion.PotionEffect;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.PlayerEvent;
import dudesmods.lozmod.lozmod3.LOZmod;

public class LOZmodEVENT {

@SubscribeEvent
public void onCrafting(PlayerEvent.ItemCraftedEvent e) {

	for(int i=0; i < e.craftMatrix.getSizeInventory(); i++)
	  {         
	      if(e.craftMatrix.getStackInSlot(i) != null)
	      {
	       ItemStack j = e.craftMatrix.getStackInSlot(i);
	       if(j.getItem() != null && j.getItem() == LOZmod.magic_powder)
	       {
	        ItemStack k = new ItemStack(LOZmod.magic_powder, 2, (j.getItemDamage() + 1));
	        e.craftMatrix.setInventorySlotContents(i, k);
	       }
	      }  
	  }
}

}

 

Stuff in main class:

@EventHandler
public void PreInitialization(FMLPreInitializationEvent event) {
//blah blah blah
FMLCommonHandler.instance().bus().register(new LOZmodEVENT());
//blah blah blah
}

Hi Diesievben07

 

I've tried to do this but i cant....

 

MainClass:

 

package dk.vikke.lefood;

 

import net.minecraft.creativetab.CreativeTabs;

import net.minecraft.init.Items;

import net.minecraft.item.Item;

import net.minecraft.item.Item.ToolMaterial;

import net.minecraft.item.ItemStack;

import net.minecraftforge.common.util.EnumHelper;

import cpw.mods.fml.common.FMLCommonHandler;

import cpw.mods.fml.common.Mod;

import cpw.mods.fml.common.Mod.EventHandler;

import cpw.mods.fml.common.event.FMLPreInitializationEvent;

import cpw.mods.fml.common.eventhandler.Event;

import cpw.mods.fml.common.registry.GameRegistry;

import dk.vikke.lefood.items.BSlice;

import dk.vikke.lefood.items.Knife;

 

@Mod(modid = MainClass.MODID, name = MainClass.NAME, version = MainClass.VERSION)

public class MainClass {

public static final String MODID = "lefood";

public static final String NAME = "Le Food";

public static final String VERSION = "1.0.0";

 

//Creative Tab

public static CreativeTabs leFoodTaB = new CreativeTabs("leFoodTab") {

@Override

public Item getTabIconItem() {

return BSlice;

}

};

 

//Food

public static Item BSlice = new BSlice(2, 0.3F, false).setUnlocalizedName("BSlice");

 

//Tools

public static ToolMaterial leFoodKnife = EnumHelper.addToolMaterial("leFoodKife", 0, 19, 1.0F, 1.0F, 0);

public static Item Knife = new Knife(leFoodKnife).setMaxStackSize(1).setUnlocalizedName("Knife");

 

public MainClass() {

//Registry

GameRegistry.registerItem(BSlice, "BSlice");

GameRegistry.registerItem(Knife, "Knife");

 

//Crafting

GameRegistry.addShapelessRecipe(new ItemStack(BSlice, 2), new ItemStack(Items.bread), new ItemStack(Knife.setContainerItem(Knife)));

GameRegistry.addShapedRecipe(new ItemStack(Knife, 1), new Object[]{ "X", "Z", 'X', Items.iron_ingot, 'Z', Items.stick});

}

}

 

 

Knife Class:

 

package dk.vikke.lefood.items;

 

import dk.vikke.lefood.MainClass;

import net.minecraft.item.Item;

import net.minecraft.item.ItemStack;

import net.minecraft.item.ItemSword;

 

public class Knife extends ItemSword {

 

public Knife(ToolMaterial id) {

super(id);

this.setCreativeTab(MainClass.leFoodTaB);

this.setTextureName(MainClass.MODID + ":" + "Knife");

 

@Override

this.getContainerItem();

this.hasContainerItem(true);

}

 

}

 

package yourpackage;

public class item_damagable extends Item{

public String data ="mod"+ ":" + this.getClass().getName();

public item_damagable()

    {

        super();

        setMaxStackSize(1);

        setNoRepair();

        setMaxDamage(128);  //how often is it usable? now 128

        this.setUnlocalizedName(data);

        this.setTextureName(data);

        this.setCreativeTab(tab);

    }

 

@SideOnly(Side.CLIENT)

    public boolean hasEffect(ItemStack par1ItemStack)            // the item has a enchanting effect. delete it if you don't want it

    {

        return true;

    }

 

    @Override

    public boolean doesContainerItemLeaveCraftingGrid(ItemStack itemStack)

    {

        return false;

    }

 

    @Override

    public boolean getShareTag()

    {

        return true;

    }

 

    public boolean hasContainerItem(ItemStack itemStack)

    {

    return true;

    }

    @Override

    public ItemStack getContainerItem(ItemStack itemStack)

    {

        ItemStack stack = itemStack.copy();

 

        stack.setItemDamage(stack.getItemDamage() + 1);

        stack.stackSize = 1;

 

        return stack;

    }

   

And in the crafting recipe like this:

GameRegistry.addShapelessRecipe(new ItemStack(Blocks.tallgrass, 1 , 0), new ItemStack(Blocks.tallgrass, 1 , 3), new ItemStack(ITEMNAMEOFTHEITEMTHATTAKESDAMAGE, 1, OreDictionary.WILDCARD_VALUE));

 

Hope that helps

Hi SantacreeperLP

 

Your code worked after i edited some stuff

Im so thanks full

 

Heres my code now:

 

Knife Class

 

package dk.vikke.lefood.items;

 

import net.minecraft.item.Item;

import net.minecraft.item.ItemStack;

import cpw.mods.fml.relauncher.Side;

import cpw.mods.fml.relauncher.SideOnly;

import dk.vikke.lefood.MainClass;

 

 

public class Knife extends Item{

  public String data ="mod"+ ":" + this.getClass().getName();

  public Knife()

    {

        super();

        setMaxStackSize(1);

        setNoRepair();

        setMaxDamage(19);  //how often is it usable? now 128

        this.setUnlocalizedName("Knife");

        this.setTextureName(MainClass.MODID + ":" + "Knife");

        this.setCreativeTab(MainClass.leFoodTab);

    }

 

    @Override

    public boolean doesContainerItemLeaveCraftingGrid(ItemStack itemStack)

    {

        return false;

    }

 

    @Override

    public boolean getShareTag()

    {

        return true;

    }

 

    public boolean hasContainerItem(ItemStack itemStack)

    {

      return true;

    }

    @Override

    public ItemStack getContainerItem(ItemStack itemStack)

    {

        ItemStack stack = itemStack.copy();

 

        stack.setItemDamage(stack.getItemDamage() + 1);

        stack.stackSize = 1;

 

        return stack;

    }

}

 

 

And The Recipe:

 

GameRegistry.addShapelessRecipe(new ItemStack(BSlice, 2), new ItemStack(Items.bread), new ItemStack(Knife, 1, OreDictionary.WILDCARD_VALUE));
