Hi, I am trying to add a recipe that use two of my mod items and return a new Item with a property on a nbt tag increased. My problem is that the recipe is not loaded :

Where I register my recipe :

@Mod.EventBusSubscriber(modid = ThelastofcraftMod.MODID, bus = Mod.EventBusSubscriber.Bus.FORGE)
public class ModSetup {

    public static final IRecipeSerializer<ModToolRecipe> MODTOOL_CRAFTING = null;

    public static final ItemGroup ITEM_GROUP = new ItemGroup("thelastofcraft") {
        @Override
        public ItemStack createIcon() {
            return new ItemStack(Registration.MOLOTOV_ITEM.get());
        }
    };

    public static void init(final FMLCommonSetupEvent event) {
        Networking.registerMessages();
    	for (Biome biome : ForgeRegistries.BIOMES) {
    		  biome.getSpawns(EntityClassification.MONSTER).add(new Biome.SpawnListEntry(Registration.RUNNER.get(), 60, 3, 5)); 
    	}
    }

    @SubscribeEvent
    public static void registerRecipes(final RegistryEvent.Register<IRecipeSerializer<?>> event) {
        event.getRegistry().register(new SpecialRecipeSerializer<>(ModToolRecipe::new).setRegistryName(ThelastofcraftMod.MODID, "modtool_crafting"));
    }

    @SubscribeEvent
    public static void onPlayerLoggin(PlayerEvent.PlayerLoggedInEvent event) {
    	CompoundNBT nbt = event.getEntity().getPersistentData();
    	if(!nbt.contains("TLOC_pistol")) {
    		nbt.putBoolean("TLOC_pistol", true);
    		((PlayerEntity) event.getEntity()).inventory.addItemStackToInventory(new ItemStack(Registration.PISTOL.get()));
    		((PlayerEntity) event.getEntity()).inventory.addItemStackToInventory(new ItemStack(Registration.BULLET_ITEM.get(), 6)); 
    	}
    }
    
    @SubscribeEvent
    public static void onPlayerRespawn(PlayerEvent.PlayerRespawnEvent event) {
        ((PlayerEntity) event.getEntity()).inventory.addItemStackToInventory(new ItemStack(Registration.PISTOL.get()));
        ((PlayerEntity) event.getEntity()).inventory.addItemStackToInventory(new ItemStack(Registration.BULLET_ITEM.get(), 6)); 
    }
}

 

 

My recipe :

Spoiler

public class ModToolRecipe extends SpecialRecipe {

    public ModToolRecipe(ResourceLocation res) {
        super(res);
    }

    @Override
    public boolean matches(CraftingInventory inv, World worldIn) {
        ArrayList<ItemStack> modtool = new ArrayList<ItemStack>();
        for (int i = 0; i < inv.getSizeInventory(); i++) {
            ItemStack stack = inv.getStackInSlot(i);
            if (stack.getItem() == Registration.MODTOOL.get()) {
                modtool.add(stack);
            } else if(!stack.isEmpty()) {
                return false;
            }
        }
        
        return ModTool.readUpgradeAcquired(modtool.get(0)) == ModTool.readUpgradeAcquired(modtool.get(1)) && modtool.size() == 2;
    }

    @Override
    public ItemStack getCraftingResult(CraftingInventory inv) {
        ArrayList<ItemStack> modtool = Lists.newArrayList();
        for (int i = 0; i < inv.getSizeInventory(); i++) {
            ItemStack stack = inv.getStackInSlot(i);
            if (stack.getItem() == Registration.MODTOOL.get()) {
                modtool.add(stack);
            }else if(!stack.isEmpty()) {
                return ItemStack.EMPTY;
            }
        }
        if(modtool.size() != 2)
            return ItemStack.EMPTY;

        if(ModTool.readUpgradeAcquired(modtool.get(0)) != ModTool.readUpgradeAcquired(modtool.get(1)))
            return ItemStack.EMPTY;
        else {
            ItemStack itemout = new ItemStack(Registration.MODTOOL.get());
            ModTool.writeUpgradeAcquired(itemout, ModTool.readUpgradeAcquired(modtool.get(0))+1);
            return itemout;
        }
    }

    @Override
    public boolean canFit(int width, int height) {
        return width*height>=2;
    }

    @Override
    public IRecipeSerializer<?> getSerializer() {
        return ModSetup.MODTOOL_CRAFTING;
    }
}

 

and I have a json file in the recipes folder with my vanilla recipes :

{
  "type": "thelastofcraft:modtool_crafting"
}
