I'm trying to make a block that uses a special crafting system

There are two inputs and one output

I'm getting stuck at the part were I ask for the recipe list

I want the crafting to be like in an anvil/alchemy station

I just fix it with the finding of the recipe class but now it removes the items that will be used in the recipe and returns nothing.

Class Recipe: https://github.com/NeoSup2130/Neo/blob/master/BloodTransRecipe

 

Not the cause but should your <=1 should be <= 0

 

 

 

if(this.slots[0].stackSize <= 0 && this.slots[1].stackSize <= 1) {

this.slots[0] = null;

this.slots[1] = null;

System.out.println("Aaaaaand it's gone");

}

 

 

 

right below "ItemStack itemstack = BloodTransRecipe.Transforming().getTransformingResult(this.slots[0]);", put a print statement to make see what it is telling you it found as an item.  That will probably answer what is up.  I'm betting it is null.

 

 

I haven't messed with custom recipes like that much, but something is up.  you are passing in two source items, but only using the first one as you progress through your functions.

 

 

    private BloodTransRecipe()

    {

        this.func_151396_a(Items.iron_sword, MainClass.CorruptedBlood, new ItemStack(MainClass.CorruptedIronSword));

    }

 

    public void func_151396_a(Item inputI, Item inputI2, ItemStack output)

    {

        this.func_151394_a(new ItemStack(inputI, 1, 32767), output);

    }

 

    public void func_151394_a(ItemStack inputI, ItemStack output)

    {

        this.CraftList.put(inputI, output);

    }

 

 

 

right below "ItemStack itemstack = BloodTransRecipe.Transforming().getTransformingResult(this.slots[0]);", put a print statement to make see what it is telling you it found as an item.  That will probably answer what is up.  I'm betting it is null.

True I'm not returning anything back

Maybe the recipe class is messed up....

I bet that's what it is

Can someone help please?

Did you look at the other items I mentioned above?

Yes

And it didn't return anything when I did System.out.println(itemstack);

I told you to look at two other things than that.

I just fixed it !

Thanks delpi
