it seems that calling Item.getItemFromBlock returns null for any modded block. It is being called outside of the main class, so that might influence it.

I register my blocks like this:

b.setRegistryName(name);
GameRegistry.register(b);

Am i missing anything?

The new registry system does not automatically register an item for a block you have to manually register an itemblock for it.

Thanks. Seems odd it wouldn't be included, seeming as the old version did include it.

It's like that because it is a generic register not one specifically for blocks. So the same method is used for items,blocks,sounds,potions and enchantments.

NOT ALL BLOCKS NEED ITEMS!

The old method is a LONG standing hangover from back in the day when we had to make sure both were the same ID in the constructor.

Now, they are completely separate registries with no real link between the two.

 

If you want an item, then opt in for a item.
