Hello, how would I make an item retain its damage after being crafted with something else?

 

Item:

package tf2crates.item;

import java.util.List;

import net.minecraft.client.renderer.texture.IIconRegister;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.EnumRarity;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.EnumChatFormatting;
import net.minecraft.util.IIcon;
import net.minecraft.util.StatCollector;
import tf2crates.ReferenceTC;
import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;

public class ItemPaint extends Item {
public static final String[] TYPES = { "black", "red", "green", "brown", "blue", "purple", "cyan", "silver", "gray", "pink", "lime", "yellow", "lightBlue", "magenta", "orange", "white" };
public IIcon[] textures;

public ItemPaint() {
	super();

	this.setUnlocalizedName("paint");
	this.setMaxStackSize(1);

	this.hasSubtypes = true;

	this.setContainerItem(this);
}

@Override
@SideOnly(Side.CLIENT)
public void registerIcons(IIconRegister iconRegister) {
	textures = new IIcon[TYPES.length];

	for(int i = 0; i < TYPES.length; i++) {
		textures[i] = iconRegister.registerIcon(ReferenceTC.ID + ":paint/" + TYPES[i]);
	}
}

@Override
public String getItemStackDisplayName(ItemStack itemStack) {
	String res = StatCollector.translateToLocal("paint." + TYPES[itemStack.getItemDamage()] + ".name");
	return res;
}

@Override
@SideOnly(Side.CLIENT)
public void getSubItems(Item item, CreativeTabs tabs, List list) {
	for(int i = 0; i < TYPES.length; i++) {
		list.add(new ItemStack(item, 1, i));
	}
}

@Override
public EnumRarity getRarity(ItemStack itemStack) {
	return EnumRarity.rare;
}

@Override
@SideOnly(Side.CLIENT)
public void addInformation(ItemStack itemStack, EntityPlayer player, List info, boolean f) {
	info.add(EnumChatFormatting.YELLOW + "Combine this with the helmet of your choice!");
}

@Override
@SideOnly(Side.CLIENT)
public IIcon getIconFromDamage(int dmg) {
	return textures[dmg];
}

@Override
public boolean doesContainerItemLeaveCraftingGrid(ItemStack itemStack) {
	return false;
}
}

 

Recipe:

public boolean doesContainerItemLeaveCraftingGrid(ItemStack p_77630_1_)

 

I was able to make the item persist through crafting, but it resets its damage. I've seen some people recommend using a recipe handler (IRecipe), but it doesn't seem like there's anything to help with achieving this.

If your paint is like dye, then I think you need a separate recipe for each color (use a loop with a var incrementing 0-15 which gets applied to the itemStacks in your recipe statement). Unfortunately, I can't see your recipe in the box labeled "recipe", so I can't see what you're trying to do.

Oh, I must've not copy and pasted the right code segment haha

 

I was able to get the recipes working:

for(i = 0; i < 16; i++) {
   GameRegistry.addShapelessRecipe(new ItemStack(Blocks.wool, 1, BlockColored.func_150031_c(i)), new ItemStack(paint, 1, i), new ItemStack(Blocks.wool, 1, 0));
}

With that set of recipes, you can paint white wool into any color wool. If you want to paint from color to color, I think you can replace the white wool's zero "damage" with a wildcard value.

 

If you wanted to, you might also play with the stack sizes so that one paint could color several wool blocks (e.g. 4 wool in and 4 wool out for each paint used).
