Remove Vanilla Recipes

[drok0920]

Hello,

I have a need to remove vanilla recipes as i am changing the progression of the game.  I have tried to just remove them from RecipeManager.REGISTRY but there doesnt seem to be a way to remove item from it.  How can i remove them and in what event should i remove them.  I am currently doing it onWorldLoad and only on the server is this correct?

You have to cast the registry during the Register<IRecipe> event to IForgeRegistryModifiable.

 

Note that straight removing the recipe will cause an error during advancement loading, as the advancement that unlocks the removed recipe will fail to deserialize.

Can you explain what this Register(IRecipe) method is?  And advancements aren't and issue as i have removed them too.

If you remove the recipe, the advancement fails to deserialize, you don't get a chance to remove it.

Is there a way to prevent this other than manually overriding each recipe.

No.

No.

Can i at least turn off the error notifications for it?

Ok then my final question is does that cause a performance difference?  The errors that is.

[Draco18s]

The error occurs during startup. It has no impact during play.

[Choonster]

You can also override the recipes with dummy recipes that do nothing, as I do here. The DummyRecipe class is here.

 

This prevents the advancement errors, but instead spams the log with "Dangerous alternative prefix" warnings because you need to set the registry names of the dummy recipes to the registry names of the vanilla recipes they override. As LexManos said here, there's currently no way to avoid this.

(Which is a "manually overriding each recipe" type solution)

It is overriding each recipe, but I'd argue that's it no more manual than removing them. Either way you need to specify which recipes to override/remove, overriding them only requires one additional class; you don't need to create a class or JSON file per recipe or anything like that.

[drok0920]

I have tried the method that Choonster stated but i am getting a null pointer exception when i use the following code.

 

@SubscribeEvent(priority = EventPriority.LOWEST)
	public static void removeRecipes(final RegistryEvent.Register<IRecipe> event) {
		if(ModConfig.overrides.recipes) {
			int recipesRemoved = 0;

			final IForgeRegistry<IRecipe> registry = ForgeRegistries.RECIPES;
			final List<IRecipe> toRemove = new ArrayList<>();
			
			for(IRecipe recipe : registry) {
				if(recipe.getRegistryName().getResourceDomain().equals("minecraft")) {
					toRemove.add(recipe);
					recipesRemoved++;
				}
			}
			
			POverhaul.logInfo("Overriding " + recipesRemoved + " recipes with dummy recipes, "
					+ "please ignore the following \"Dangerous alternative prefix\" warnings.");
			for(IRecipe recipe : toRemove) {
				final IRecipe replacement = new DummyRecipe().setRegistryName(recipe.getRegistryName());
				registry.register(replacement);
			}
		}
	}

 

 

and the error is:

Edit:

Is it deleting every recipe and that is why it is null?  If so how do i only remove the vanilla recipes and not my own.  Is there a specific way that i need to register my recipes so that they are not removed.

I haven't encountered that error before, but I haven't tried to remove every vanilla recipe.

 

My code doesn't delete any recipes, it just overrides them with new recipes that do nothing. Your code is only overriding vanilla recipes, it shouldn't be touching any mod recipes.

 

Set an exception breakpoint for NullPointerException and filter it to only include exceptions thrown from the GuiButtonRecipeTab class. When this exception is thrown on line 146, look at what's null (I think it can only be the list local variable) and what the value of GuiButtonRecipeTab#category is.

Although i struggled to get the breakpoint to work or to view the variable i believe it is null because there are no recipes for some tabs.  Do you have any idea why this is a problem or if it is even the actual problem.

Any ideas?  Im really stumped on this.
