[1.10.2] Get all subtypes of an item

[Saucier]

I'm currently trying to get an item by its registry name and return all subtypes which are registered for said item as ItemStacks.

 

Example:

I use Item.getByNameOrId("minecraft:log") to get an instance of minecrafts log item.

Now I want to get all registered subtypes as ItemStacks and store them in a list.

The output would be: [1xtile.log@0, 1xtile.log@1, 1xtile.log@2, 1xtile.log@3] (Oak Wood, Spruce Wood, Birch Wood, Jungle Wood)

 

Getting the subtypes is kind of a problem. I tried to use the item#getSubItems function which works fine, but the function is marked as client-only for Minecraft versions 1.7 to 1.11 which means it would crash the server.

 

Test code (Works client-side but not server-side):

public static void printSubtypes(String regname) {
	Item item = Item.getByNameOrId(regname);
	if (item != null) {
		List<ItemStack> subtypes = new ArrayList<ItemStack>();
		item.getSubItems(item, null, subtypes);
		System.out.println(subtypes);
	} else {
		System.out.println("Item does not exist: " + regname);
	}
}

 

Is there any other easy workaround?

 

Thanks.

I know, that's why I'm looking for a solution for 1.10.

In older versions I would grab the list client side and send packet to server during the post init loading stage. 

 

Useful for things like generating random drops.
