[1.12.2] What does take to make an item have an nbt tag by default

[Issac29]

Hello, and looks like I made the attack speed lower and damage higher. How do I add an nbt tag into an item by default.

[Issac29]

I tried doing that but it still gave me the default non-nbt item.

@Override
  public void getSubItems(CreativeTabs tab, NonNullList<ItemStack> items) {
  NBTTagCompound nbt = new NBTTagCompound();
  nbt.setInteger("HideFlags", 2);
  if (this.isInCreativeTab(tab)) {
    items.add(new ItemStack(this, 1, 0, nbt));
  }
}

Here is the code.

That's because you never do anything with the compound you made. You need to set the stack's NBT to be the tag, using ItemStack#setTagCompound().
