[1.10.2] Get a random metadata Item

Recommended Posts

Hi. I'm trying to make my first mod. 

On my mod, when I right click with item A,  I get another item B(ModItems.konpen).

And I registered metadata of item B.

Now I want to change to " another random metadata item."

Please teach me how I can do it.

 

 

here is current code.

Spoiler

@Override
    public ActionResult<ItemStack> onItemRightClick(ItemStack stack, World world, EntityPlayer player, EnumHand hand) {
            player.attackEntityFrom(DamageSource.magic, 4.0F);
            player.getHeldItem(hand).stackSize--;
            player.inventory.addItemStackToInventory(new ItemStack(ModItems.konpen));
        return super.onItemRightClick(stack, world, player, hand);
    }

To make an ItemStack with metadata, use the constructor new ItemStack(item, stackSize, metadata). To get a random number for the metadata you can use the method Random#nextInt(max), which returns an integer between 0 and max-1. World has a rand field which you can use for this.
