[1.15.2] Adding vanilla items with NBT data to a new Creative Tab

[squidlex]

Hi there,

I'm trying to add existing vanilla items to a new Creative Tab.

I've already created my tab, but I don't know how to add vanilla items, let alone with NBT data stored in them.

 

Say for example I want to add a chest with NBT data to a new tab.

 

Any help would be greatly appreciated!

A working example is here

Override fill in your ItemGroup class and add whatever stacks you desire to the provided list.

Thank you both for you replies!

 

Would you be able to explain why this won't show up? It worked with modded items but not when using the override method.

public class ModItemGroup extends ItemGroup {

	public ModItemGroup(int index, String label) {
		super(index, label);
	}

	@Override
	public ItemStack createIcon() {
		return new ItemStack(Items.DRAGON_EGG);
	}

	@Override
	public void fill(NonNullList<ItemStack> items) {
		items.add(new ItemStack(Items.DRAGON_EGG));
	}
}

 

I fixed it, it was an error with me hardcoding an index like an idiot.

Thanks for all your help!

So I now have the Creative Tab down, but how do I add NBT data to an ItemStack?

At the moment I'm messing with ItemStack.write() but I don't know if that's correct or how to properly format NBT within it.

The write in Itemstack is something that writes an itemstack in a nbt tag iirc. What you are looking for should be either create a new CompoundNBT or getTag from the itemstack and use compound.putInt()... putBoolean... etc
