RESOLVED [1.7.10-] Damaging crafting item bug?


Recommended Posts

Okay. I've tried everything, and I cannot figure out what I'm doing wrong. This seems like the only help there is on this subject: http://pastebin.com/SnPaAvUd, and it doesn't work. Instead of the item being damaged, it gets used up. This is my code that I'm working with:


// My item class.

public class ItemKnifeBase extends Item {

public ItemKnifeBase(ToolMaterial material) {
	this.setUnlocalizedName(ToolForgeryMod.MOD_ID + ":knife_" + material.toString().toLowerCase());
	this.setTextureName(ToolForgeryMod.RESOURCES_PREFIX + "knife_" + material.toString().toLowerCase());

public ItemStack getContainerItem(ItemStack itemStack) {
	ItemStack result = itemStack.copy();
	result.setItemDamage(result.getItemDamage() + 1);
	result.stackSize = 1;
	return result;

public boolean doesContainerItemLeaveCraftingGrid(ItemStack p_77630_1_) {
	return false;



// Registering the crafting recipe in the preInit() method.

GameRegistry.addShapelessRecipe(new ItemStack(Blocks.planks, 4, 0), new ItemStack(Blocks.log, 1, 0), new ItemStack(TFItems.knife_stone, 1, OreDictionary.WILDCARD_VALUE));


To clarify, the recipe shows up, and I can use it, but instead of damaging the knife, the knife gets used up. And I'm registering the item before the recipe.


SOLUTION: You need to add


public boolean hasContainerItem() {
return true;


to the item's class.

if (user.hasKnowledgeOfJava) {

    if (user.question.hasCode) {

        return interpetHelpfulResponse(user.getQuestion());

    } else {

        return "Could you post your code please?";


} else {

    return "Learn some freaking Java!";
