Hello everyone, i am creating a multiplier item that when registered/the constructor is called, it uses reflections to get all the fields that are an Item or extends Item and creates a shapeless recipe based off it.

I would post this in Stack Overflow but I do not think that they would understand since most of them probably to not create modifications in Forge.

Here is the constructor code:

public ItemMultiplier() {
	GameRegistry.registerItem(this, name);
	setUnlocalizedName(ItemsOStupidity.MODID + ":" + name);
	setCreativeTab(CreativeTabs.tabTools);
	Field[] items0 = Items.class.getFields();
	Field[] items1 = new Field[] {};
	for (Field f : items0) {
		if (f.getType() == Item.class
				|| f.getType().getSuperclass() == Item.class) {
			List<Field> items_list = new LinkedList<Field>(
					Arrays.asList(items1));
			items_list.add(f);
			items1 = items_list.toArray(new Field[items_list.size()]);
		}
	}
	for (Field f : items1) {
		try {
			Item i = (Item) f.get(this);
		} catch (IllegalArgumentException e) {
			e.printStackTrace();
		} catch (IllegalAccessException e) {
			e.printStackTrace();
		}
	}
}

I checked out and only a few items were working with my multiplier class.

What's the problem?

Well, where do you add the recipes?

Uhm... that's not how you get all Items. Use

Item.itemRegistry

.

That way is possible too, just more laggy though.

This is my code now:

public ItemMultiplier() {
	GameRegistry.registerItem(this, name);
	setUnlocalizedName(ItemsOStupidity.MODID + ":" + name);
	setCreativeTab(CreativeTabs.tabTools);
	while(Item.itemRegistry.iterator().hasNext()) {
		Item i = (Item) Item.itemRegistry.iterator().next();
		GameRegistry.addShapelessRecipe(new ItemStack(i, 2), this, i);
	}
}

But now i see the console stuck on this:

[23:09:06] [Client thread/INFO] [FML]: Processing ObjectHolder annotations

[23:09:06] [Client thread/INFO] [FML]: Found 384 ObjectHolder annotations

and Minecraft has a black screen.

I checked out a bunch of websites, and I do not see anything wrong with my code.

Ah, I get it now, thank you alot!
