I've been struggling to find through searching an answer to do this so I'm asking. I understand how to use the getContainerItem yet I can't seem to get it to work when the item I am crafting with is a block. Basically I have a block "Crusher Module" and when you craft it with one of the 4 tiers of machine frames it gives the appropriate tier "Crusher", I want to add a shapeless recipe where if you place a "Crusher" in the crafting grid it will return the "Crusher Module" as output and leave an empty machine frame of the appropriate tier in the crafting grid. Here is the code I have in the class for the Tier 1 Crusher 

	public BlockT1Crusher(String unlocalizedName, String registryName) {
		super(Material.IRON);
		this.setUnlocalizedName(unlocalizedName);
		this.setRegistryName(new ResourceLocation(Reference.MOD_ID, registryName));
		setCreativeTab(SonicTech.CREATIVE_TAB);
	}
	
	public boolean hasContainerItem() {
		return true;		
	}
	
	public Block getContainerItem() {
		return ModBlocks.tier1_frame;
	}

And this is the code for the recipe

GameRegistry.addShapelessRecipe(new ItemStack(ModBlocks.crusher_module), ModBlocks.tier1_crusher.getContainerItem(ModBlocks.tier1_frame));

Yet Eclipse is showing an error at the "getContainerItem" part of the recipe and suggests to add cast to method and when I do that I get this

GameRegistry.addShapelessRecipe(new ItemStack(ModBlocks.crusher_module), ((Item) ModBlocks.tier1_crusher).getContainerItem(ModBlocks.tier1_frame));

which then says cannot cast from block to item

 

I'm stumped on what to do to get this to work.

 

 

Container items aren't part of the recipe itself, they're handled by the crafting grid.

Ok so I removed the getContainerItem part out of the recipe and now have no errors in eclipse yet I don't get the tier1_frame returned when I craft the crusher into the module, is my code in the block class correct?
