I need to replace vanilla water bottle with empty bottle after craft, how can I do this?  I will give code if you will advice me something and error occurs.

EDIT: Version is 1.16.5

Edited April 30, 20214 yr by SuperRuper1209

it depends on wether you want the vanilla water bottle always return en empty water bottle (for any recipe that uses a water bottle), or if there is some specific recipes from your mod that you want that behaviour on

for the latter, the solution is using Special Recipes, you can look at the Book or Map cloning recipes for some example. you'll need to override the getRemainingItems method, and perform such logic there

Thanks I guess I'll try, also I need it for one specific recipe

Registry.register(Registry.RECIPE_SERIALIZER, new ResourceLocation("tds", "crafting_special_marshmallow"), Marshmallow.MarshmallowRecipe.SERIALIZER);

 

Ok I got it, use this event to register if anyone has the same problem:

public void specialRecipesRegister(final RegistryEvent.Register<IRecipeSerializer<?>> event) { event.getRegistry().register(Marshmallow.MarshmallowRecipe.SERIALIZER.setRegistryName(new ResourceLocation("tds", "crafting_special_marshmallow"))); }

it seems your problem is solved, but just a tip: when posting code to the forums, use the code block instead of the spoiler, it provides indendation and monospaced fonts which make the code actually readable

Thanks for help! Also I see diesieben07 is kinda active, i see him and draco18(or how is he named) almost in every topic
