ShapedRecipe與Lore？

Question

我正在爲我的服務器寫一個CraftBukkit插件。但我找不到如何檢查的成分項目有絕殺

ShapedRecipe packedice = new ShapedRecipe(new ItemStack(Material.PACKED_ICE)); 
packedice.shape(new String[]{"aba","bcb","aba"}).setIngredient('a', Material.PRISMARINE_SHARD).setIngredient('b', Material.GOLD_BLOCK).setIngredient('c', Material.SNOW_BALL); 
Bukkit.getServer().addRecipe(packedice); 

Answer 1

，而不是ShapedRecipe packedice = new ShapedRecipe(new ItemStack(Material.PACKED_ICE)); 你需要多一點代碼：

ItemStack i = new ItemStack(Material.PACKED_ICE); 
ItemMeta m = i.getItemMeta(); 
m.setDisplayName("CustomDisplayName") 
List<String> l = new ArrayList<String>(); 
l.add("Line 1"); 
l.add("Line 2"); 
m.setLore(l); 
i.setItemMeta(m); 
ShapedRecipe packedice = new ShapedRecipe(i); 

希望它可以幫助

// EDIT ： 對不起，我錯過了你第一次，這將檢查是否在右上角的物品有傳說"Line1"：

@EventHandler 
public void onCraft(CraftItemEvent e) { 
    ShapedRecipe packedice = YOURRECIPE; 
    if(e.getInventory().getSize() == 10 && e.getInventory().getResult().equals(packedice.getResult())) { 
     if(e.getRawSlot() == 0) { 
      ItemStack upleft = e.getInventory().getItem(1); 
      if(upleft != null && upleft.hasItemMeta() && upleft.getItemMeta().hasLore()) { 
       List<String> l = upleft.getItemMeta().getLore(); 
       if(!l.get(0).equals("Line 1")) { 
        e.setCancelled(true); 
       } 
      } 
     } 
    } 
}

不幸的是，Bukkit API不提供方式與自定義ItemMeta（項目存儲知識和NBT數據部分）註冊配方ingredientes，但你可以繞過這一限制在兩個方面：

1）註冊沒有自定義元的配方，並檢查它是否存在，當玩家嘗試創建它們時，該項目將顯示在輸出槽中，但玩家將無法獲得它。 視頻顯示進度這個例子：）https://youtu.be/zbSf_wATaGk

public void onEnable() 
{ 
    final ShapedRecipe packedice = new ShapedRecipe(new ItemStack(Material.PACKED_ICE)); 
    packedice.shape(new String[]{"aba","bcb","aba"}).setIngredient('a', Material.PRISMARINE_SHARD).setIngredient('b', Material.GOLD_BLOCK).setIngredient('c', Material.SNOW_BALL); 
    Bukkit.addRecipe(packedice); 
    Bukkit.getPluginManager().registerEvents(new Listener() 
    { 

     @EventHandler 
     void onCraft(CraftItemEvent event) 
     { 
      // Check if it's being crafted with your custom recipe 
      // You can check only the event.getRecipe().getResult() if you are not worried about recipe conflicts. 
      if(!matches(packedice, event.getInventory().getMatrix())) 
       return; 

      // The lore that will be required in all prismarine shards 
      List<String> neededLore = Arrays.asList("Line1","Line2"); 

      // Check if all prismarine shares has that lore, 
      // you can check only one of them or whatever item you want 
      // The indexes are: 
      // 0 1 2 | Shard Gold Shard 
      // 3 4 5 | Gold Snow Gold 
      // 4 7 8 | Shard Gold Shard 
      ItemStack[] matrix = event.getInventory().getMatrix(); 
      for(ItemStack item: matrix) 
       if(item != null && item.getType() == Material.PRISMARINE_SHARD) 
        if(!neededLore.equals(item.getItemMeta().getLore())) 
        { 
         event.setCancelled(true); 
         return; 
        } 
     } 
    }, this); 
} 

/** 
* Checks if a crafting matrix matches a recipe 
*/ 
public static boolean matches(ShapedRecipe recipe, ItemStack[] matrix) 
{ 
    String[] shapeStr = recipe.getShape(); 
    int len = 0; 
    for(String line : shapeStr) 
     len += line.length(); 

    char[] shape = new char[len]; 
    int shapeIndex = 0; 
    for(String line : shapeStr) 
     for(char c: line.toCharArray()) 
      shape[shapeIndex++] = c; 

    for(int i = 0; i < shape.length; i++) 
    { 
     ItemStack required = recipe.getIngredientMap().get(shape[i]); 
     ItemStack found = matrix[i]; 
     if(found == null || !required.getData().equals(found.getData())) 
      return false; 
    } 

    return true; 
} 

可以超越Bukkit API和使用CraftBukkit和的Minecraft對象進行登記，檢查的NBT標籤定製的配方對象，這樣玩家就不會看到任何輸出，除非他使用與配方中註冊的完全相同的項目，您還可以註冊重命名或附魔對象的配方。 視頻展示這個例子中的進展：https://youtu.be/Gr3ADckGBUA
