Bukkit-使用自定义配方添加自定义商品

Question

我想创建新项目。我称它为生命水晶。我还为此新项目创建了新食谱。我的问题是当我尝试制作该物品时，我制作的是普通物品而没有新的显示名称和结界。我的代码如下所示。

 // Life Crystal
        ItemStack lifecrystal = new ItemStack(Material.DIAMOND);
        NamespacedKey lifecrystalKey = new NamespacedKey((Plugin) this, "lifecrystal");
        ShapedRecipe lifecrystalRecipe = new ShapedRecipe(lifecrystalKey, lifecrystal);

        ItemMeta lifecrystalLabel = lifecrystal.getItemMeta();
        lifecrystalLabel.setDisplayName(ChatColor.GOLD + "Life Crystal");
        lifecrystalLabel.addEnchant(Enchantment.BINDING_CURSE, 1, false);
        lifecrystal.setItemMeta(lifecrystalLabel);

        lifecrystalRecipe.shape(" E ", "LAL", "DRD");
        lifecrystalRecipe.setIngredient('E', Material.EMERALD);
        lifecrystalRecipe.setIngredient('L', Material.LAPIS_LAZULI);
        lifecrystalRecipe.setIngredient('A', Material.GOLDEN_APPLE);
        lifecrystalRecipe.setIngredient('R', Material.GOLD_INGOT);
        lifecrystalRecipe.setIngredient('D', Material.DIAMOND);
        Bukkit.addRecipe(lifecrystalRecipe);

编辑：我的方法.setDisplayName显示错误：（方法调用集显示名称可能会产生null）

Answer 1

您应该首先使用所有自定义元数据制作ItemStack，然后制作配方。

    ItemStack lifecrystal = new ItemStack(Material.DIAMOND);
    ItemMeta lifecrystalLabel = lifecrystal.getItemMeta();
    lifecrystalLabel.setDisplayName(ChatColor.GOLD + "Life Crystal");
    lifecrystalLabel.addEnchant(Enchantment.BINDING_CURSE, 1, false);
    lifecrystal.setItemMeta(lifecrystalLabel);

    NamespacedKey lifecrystalKey = new NamespacedKey((Plugin) this, "lifecrystal");
    ShapedRecipe lifecrystalRecipe = new ShapedRecipe(lifecrystalKey, lifecrystal);

    lifecrystalRecipe.shape(" E ", "LAL", "DRD");
    lifecrystalRecipe.setIngredient('E', Material.EMERALD);
    lifecrystalRecipe.setIngredient('L', Material.LAPIS_LAZULI);
    lifecrystalRecipe.setIngredient('A', Material.GOLDEN_APPLE);
    lifecrystalRecipe.setIngredient('R', Material.GOLD_INGOT);
    lifecrystalRecipe.setIngredient('D', Material.DIAMOND);
    Bukkit.addRecipe(lifecrystalRecipe);
