[1.10.2] Get ingredients from Crafting Recipe

[Herobone]

Hi Guys!

I'm still working on the AllergyMod. Now i want that for example if you have an allergy against gluten, every food, that includes till the lowest crafting-step, for example wheat, should be recognized and the player gets an allergic reaction. (Doesn't sound nice but i want it for more realism in a Modpack I'm doing for a friend...)

 

So just in case I formed the sentence bad:

I want the get all ingredients of a crafting recipe. Is it possible an if yes how?

Which version of Minecraft are you using?

 

In 1.12+, use IRecipe#getIngredients to get a list of Ingredients in a recipe and Ingredient#getMatchingStacks to get a list of ItemStacks matched by an Ingredient.

 

IRecipe#getIngredients returns an empty list for special recipes with harcoded ingredients (e.g. RecipeBookCloning, RecipeFireworks, etc.), it only returns a non-empty list for recipes that use a collection of Ingredient objects (e.g. ShapedRecipes, ShapelessRecipes, ShapedOreRecipe and ShapelessOreRecipe).

Thanks but I need 1.10.2

Then you'll need to handle each recipe class individually.

 

For Vanilla's shaped/shapeless recipes, look for a field containing the collection of ItemStack ingredients.

 

For Forge's ore recipes, look for a field containing the collection of Object ingredients. Each Object can be either an ItemStack or a List<ItemStack>.

 

I strongly recommend updating to 1.12.1.

For 1.10, look at how I handled it here:

https://github.com/Draco18s/ReasonableRealism/blob/master/src/main/java/com/draco18s/hardlib/util/RecipesUtils.java#L129

Don't worry about what the function is doing but rather on how its doing it.

Thanks! Based on this I coded a function, that can look up materials in the first level. But what should I do for recipes of the second level? (For example with other mods) Detect wheat in a bread that was baked in the furnace? Or a bread that was used for crafting again? Any Ideas

[Draco18s]

There are no second level recipes, everything's "first level."

 

If you have an item that is made up of non-resource items (say bookshelves: made out of books) you have to use a lookup table to figure out how much paper is involved: you know how many books the bookshelf is made out of, then multiply by the amount of paper in each book.
