java - 有诱饵的ShapedRecipe？

我正在为服务器编写CraftBukkit插件。但是我找不到如何检查配料项目是否有知识

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);

最佳答案

代替ShapedRecipe packedice = new ShapedRecipe(new ItemStack(Material.PACKED_ICE));
您需要更多代码：

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);

希望能帮助到你

抱歉，我首先误会了您，这将检查右上角的项目是否具有Lore "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);
                }
            }
        }
    }
}
