I was making a mod for my personal use and was wondering how to iterate through all of the items in minecraft / though other mods as well if they are there.

Using this info I wanted to use each individual item to be in a separate shapeless crafting recipe that does something to that item (I'm specifying towards food items)

and got stuck at the start. How do I even Iterate through the items?

Look at Items.REGISTRY

You can access all of Forge's registries via ForgeRegistries. Note, however, that when you iterate over the registry, you will only be iterating over the things that have already been registered. If a mod loads after yours, it will not be in the list.

 

Edit: This is assuming you are doing the iterating in preInit, as Draco said below. If not, ignore that second part.

Not entirely true.  As items/blocks/etc can only be registered during PreInit, then any point after that will see every item that exists, regardless of mod load order.

are you saying that all of the things are being loaded in pre init? so should I do the iteration in the post init? Also, for what Version will this function be available under?

Items may still be being created by mods (that load after yours) during preInit, but after preInit (init, postInit, during game) the registries are finalized and cannot be modified.

 

So yes.

I just edited my post so that I had my second question in there, but what Version <= ?

Or what I am trying to say is will the be available in 1.8

 

Function? You mean init and postInit? Those methods have been around since forever.

If you mean Items.REGISTRY (which is a field) I don't know when it was added.

dang... I'll move my mods to 1.8 instead of 1.7.10 because that isn't in there...

but this loop does look right, right? 

@EventHandler
	public void init(FMLInitializationEvent event) {
	
		for (ItemStack fooditem : Items.REGISTRY){
			
		};
	}

 

The only thing though is that I hate (with love) the attack cooldown thingy, and was wondering if I could do an @override to disable it. Otherwise I would gracefully move up that far.

ahh ok. so then it would be this: 

@EventHandler
public void init(FMLInitializationEvent event) {
	for (Item fooditem : Items.REGISTRY){
		
	};
}

The only way i've seen is with plugins, but I have'nt been able to find a mod that does it

ahh ok

For the list of items, I think I tend to use:

 

List<Item> list = ImmutableList.copyOf(Item.itemRegistry);
