I'm trying to make an Item that can be refilled/repaired after it gets used up, like a Cammel pack. I already got the whole getting used up part, but now I don't find any way to reapair my item in a vanilla crafting grit. It also should keep its NBT.

 

Any help is greatly appreciated. Thanks!!

A little more information is required, ,

how are you wanting to repair / refill the the item ,

custom block,?

putting it on the crafting table with another item to refill/recharge ?

 

 

I want to use the crafting bench/survival grid and a custom Item to repair it.

ok, in one of my mods i created a recipe that sets an item to data in another item,

this is how a player uses it,

put both items on the crafting table , and its done automatically the items remain on the crafting grid

 

here is the recipe

package me.el.LoonTools;

import net.minecraft.inventory.InventoryCrafting;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.item.crafting.IRecipe;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;

public class TrackerRecipe implements IRecipe {

public ItemStack getCraftingResult(InventoryCrafting inv) {
	return null;
}

public ItemStack getRecipeOutput() {
	return null;
}

public int getRecipeSize() {
	return 0;
}

public boolean matches(InventoryCrafting inv, World w) {
	ItemStack cr=null;
	ItemStack tr=null;
	int sn=0;
	for (int s=0;s<inv.getSizeInventory();s++){
		ItemStack i=inv.getStackInSlot(s);
		if (i!=null){
			Item it = i.getItem();
			if(it instanceof ItemCrystal){
				if (cr!=null) return false;
				cr=i;
			}else if(it instanceof ItemLocationTracker){
				if (tr!=null) return false;
				tr=i;
				sn=s;
			}else return false;
		}
	}
	if(cr==null || tr==null) return false;

	if (!cr.hasTagCompound()) return false;

	try {
		NBTTagCompound c = cr.getTagCompound();
		float x=c.getFloat("bx");
		float z=c.getFloat("bz");
		String wld=c.getString("bw");

		NBTTagCompound t;
		if (tr.hasTagCompound()){
			t=tr.getTagCompound();
			try {
				float tx = t.getFloat("bx");
				float tz = t.getFloat("bz");
				String tw=t.getString("bw");
				System.out.println(tx+" "+tz+" "+tw);
				System.out.println(x+" "+z+" "+wld);
				if (x==tx && z==tz && tw.equals(wld)) return false;
			} catch (Exception e) {
			}
		}else{
			t=new NBTTagCompound();
		}


		t.setFloat("bx", x);
		t.setFloat("bz", z);
		t.setString("bw", wld);

		ItemStack result = tr.copy();
		result.setTagCompound(t);
		result.setStackDisplayName(cr.getDisplayName());
		inv.setInventorySlotContents(sn, result);
		return false;
	} catch (Exception e) {
		return false;
	}
}
}

 

you will notice that everything is done in the matches method

you will also notice that matches always returns false, this prevents items being lost by consumption during crafting

 

Hope this helps

 

here is a brief explanation of the process

 

search slots for items you dont want on the crafting table

also getting the slot numbers of the items you do want

 

then perform the changes to the items

 

simple

 

oh, another thing you need to make sure of, is that you only make changes and replace the items on the crafting grid when necessary , otherwise you get a non exiting loop and a stack error crash

 

so in your case if the item is full / repaired , or the filling/repairing item is empty, exit with out changing either item

 

Thanks. Code should do, just I dont know how to implement it in my base class (register in GameRegistry like Craftinghandler?). Also I suppose your code doesnt need a recipe that you modify, like the CraftingHandler does, right?

 

Edit: Its a IRecipe, so I suppose I have to register a recipe?!

once you have created your recipe add it with

 

GameRegistry.addRecipe(new TrackerRecipe());

in your init event

 

Thanks, mate, you are a great help. I'm jumping to work now. I hope I'm not that dumb to fuck it up

If you, yes YOU, also want an item that is repaired in the crafting table or in the survival crafting grid then feel free to use this code

 

 

public boolean matches(InventoryCrafting inventory, World world) {
	ItemStack itemThatWillBeRepaired = null;
	ItemStack itemThatIsUsedToRepaire = null;
	for (int i=0; i < inventory.getSizeInventory(); i++){
		ItemStack itemStack = inventory.getStackInSlot(i);
			if (itemStack != null){
				if (itemStack.getItem() == YourMod.itemThatWillBeRepaired){
					if (itemThatWillBeRepaired != null)return false;
					itemThatWillBeRepaired = itemStack;
				}else if (itemStack.getItem() == Items.stick){
					if (itemThatIsUsedToRepaire != null)return false;
					itemThatIsUsedToRepaire = itemStack;
				}
			}
	}
	return itemThatWillBeRepaired != null && itemThatIsUsedToRepaire != null;
}

public int getRecipeSize() {
	return 9;
}
