Removing Vanilla Recipes

[Rohzek]

Ironically just a few weeks ago now I answered a similar question with the extent of my knowledge on it... However I seem to have a few holes in my method.

In a quest to toughen up vanilla recipes I'm using the following method to find and remove crafting recipes so that I can replace them:

 

 

 

public static void removeCraftingRecipe(Item item)
{
     List<IRecipe> recipes = CraftingManager.getInstance().getRecipeList();
     Iterator<IRecipe> remover = recipes.iterator();
     
     while(remover.hasNext())
     {
    	// If the output matches the specified item. Can be used with itemstacks directly or getitemfromblock as well.
    	 ItemStack itemstack = remover.next().getRecipeOutput();

			if(itemstack != null && itemstack.getItem() == item)
			{
				// Remove the recipe
				remover.remove();
			}
     }
}

 

 

 

which works fine for 99.99% of recipes... However it doesn't seem to remove Fireworks, Dyes, or Stained Clay blocks. These seem to just.. not be there. Checking the specific Recipes classes don't seem to help much. Dyes seem to be added to A crafting manager normally... but not the list in CraftingManager I guess... Fireworks don't.. I don't even know where the recipe for stained clay is?

 

Not sure how to find and remove these.

Recipes for Dyes and coloured blocks (e.g. Stained Clay) are added by

RecipeDyes#addRecipes

, which is called from the

CraftingManager

constructor. They're just standard shaped/shapeless recipes, so your method should remove them without issue.

 

Fireworks recipes are handled by the

RecipeFireworks

class, which returns

null

from

IRecipe#getRecipeOutput

until

IRecipe#matches

has found a matching recipe; so you can't remove it based on the output

Item

. You can remove it based on the class instead, though.

 

You can see a working example of this for 1.8 here. This outputs the following to the log:

Removed 1 recipes for class net.minecraft.item.crafting.RecipeFireworks

Removed 28 recipes for minecraft:dye

Removed 16 recipes for minecraft:stained_hardened_clay

To be honest I probably don't want to remove the Firework recipes.. Too many combos to play with just trying to make it harder.. But it's interesting to know how, thanks.

 

As for the dyes, I made a stupid mistake  I wasn't actually USING that method, I was iterating through an itemstack of the dyes and checking each metadata value directly against the itemstack. And similar with the blocks with a for loop and checking each for a recipe which was just fizzling.

Just passing the item itself totally works as intended.

Thanks again for that too. No telling how long I would have wasted not figuring out that.
