From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jake Potrebic Date: Sun, 12 May 2024 10:42:42 -0700 Subject: [PATCH] Fix issues with recipe API Improves the validation when creating recipes and RecipeChoices to closer match what is allowed by the Codecs and StreamCodecs internally. Adds RecipeChoice#empty which is allowed in specific recipes and ingredient slots. Also fixes some issues regarding mutability of both ItemStack and implementations of RecipeChoice. diff --git a/src/main/java/org/bukkit/inventory/CookingRecipe.java b/src/main/java/org/bukkit/inventory/CookingRecipe.java index f7fa79393aef40027446b78bac8e9490cfafd8bc..07906ca1a9b39fcc6774870daa498402f7f37917 100644 --- a/src/main/java/org/bukkit/inventory/CookingRecipe.java +++ b/src/main/java/org/bukkit/inventory/CookingRecipe.java @@ -44,10 +44,10 @@ public abstract class CookingRecipe implements Recipe, * @param cookingTime The cooking time (in ticks) */ public CookingRecipe(@NotNull NamespacedKey key, @NotNull ItemStack result, @NotNull RecipeChoice input, float experience, int cookingTime) { - Preconditions.checkArgument(result.getType() != Material.AIR, "Recipe must have non-AIR result.");
