So I am curious on this idea I have. I am thinking of making this item and give it a NBTTagCompound of uses, I would set it to 5 uses, Now what I want to do is when used in crafting it will not consume the item and set the uses to 4(3,2,1,0). Once it hits 0 I want it to then consume the item.

 

Mock code/idea:

public boolean hasContainerItem(ItemStack itemStack)
    {
       return true;
    }
    @Override
    public ItemStack getContainerItem(ItemStack itemStack)
    {
        ItemStack stack = itemStack.copy();
        
         if(uses !=0){
  
        stack.setItemDamage(stack.getItemDamage() - 1);
}
else {
//allow item to be removed 
}
        

        return stack;
    }

 

now the one thing is I don't know how to make the item not be used up when crafted, and I was debating on using the oncreated() function but read that, that's best to use only for vanilla crafting tables.

again this was more of a thought, I'm more curious if this would work or not and like I said it was a mock code I don't actually have that code any where so technically there is no where uses is being defined, but I would define like this

// I don't fully know where I would put this cause the item will not be crafted but found in a chest
stack.setTagCompound(new NBTTagCompound());
stack.stackTagCompound.setInteger("uses", 4);

 

then I would use stack.getTagCompound().getInteger("uses") to define uses

"// I don't fully know where I would put this cause the item will not be crafted but found in a chest" The best way to handle something like that is to check if the tag exists before you read it and if it dose not then you create it. It helps to have an NBT helper class to do all that for you.

again Mock Code if I was to actually put this in which i will soon, I would check to see if the NBTtag exists if not then to create it,

now the one thing is I don't know how to make the item not be used up when crafted I think that is my initial place to start.

 

I also want to apologize for my scatter brain, this is just how I think and work.

 

It depends on what exactly it is you want to do. You will need to ether make it a container item or create your own IRecipe implementation

 

Like I said in my first post what I am looking to do is have this item not be used up in crafting until its uses hits 0 again the reason why we were talking about the uses NBTTag, even though that part I knew how to do, the part I don't know is the item not being used up part.

 

Not to sound rude but did any one read the first post fully, or was it just the way I worded things. If it was the way I word things I want to apologize.

I am guessing no help?

Wait really but I thought container item still gets used when crafted with, and if it doesn't how would I make it use the item up once it hits 0.

 

I'm just really confused now

I totally forgot about the has container item part duh it works i finally made the full on code thank you desbien, again I apologize I'm just a total scatter brain
