java - 使用 Eclipse 的 Minecraft 模组在运行时出现错误

Question

我用一个 block 制作了一个工具，我在代码中没有犯任何错误。当我尝试单击“构建”时，它给出了此终端错误:我怎样才能解决这个问题？请。这是 RecipesTools.addRecipes 的代码

package net.minecraft.src;

public class RecipesTools
{
    private String recipePatterns[][] =
    {
        {
            "XXX", " # ", " # "
        }, {
            "X", "#", "#"
        }, {
            "XX", "X#", " #"
        }, {
            "XX", " #", " #"
        }
    };
    private Object recipeItems[][];

    public RecipesTools()
    {
        recipeItems = (new Object[][]
                {
                    new Object[] {
                        Block.planks, Block.cobblestone, Item.ingotIron, Item.diamond, Item.ingotGold,  Block.RadiatedStone
                    }, new Object[] {
                        Item.pickaxeWood, Item.pickaxeStone, Item.pickaxeSteel, Item.pickaxeDiamond, Item.pickaxeGold, Item.pickaxeRadiated
                    }, new Object[] {
                        Item.shovelWood, Item.shovelStone, Item.shovelSteel, Item.shovelDiamond, Item.shovelGold
                    }, new Object[] {
                        Item.axeWood, Item.axeStone, Item.axeSteel, Item.axeDiamond, Item.axeGold
                    }, new Object[] {
                        Item.hoeWood, Item.hoeStone, Item.hoeSteel, Item.hoeDiamond, Item.hoeGold
                    }
                });
    }

    public void addRecipes(CraftingManager craftingmanager)
    {
        for (int i = 0; i < recipeItems[0].length; i++)
        {
            Object obj = recipeItems[0][i];
            for (int j = 0; j < recipeItems.length - 1; j++)
            {
                Item item = (Item)recipeItems[j + 1][i];
                craftingmanager.addRecipe(new ItemStack(item), new Object[]
                        {
                            recipePatterns[j], Character.valueOf('#'), Item.stick, Character.valueOf('X'), obj
                        });
            }
        }

        craftingmanager.addRecipe(new ItemStack(Item.shears), new Object[]
                {
                    " #", "# ", Character.valueOf('#'), Item.ingotIron
                });
    }
}

编辑我还给了 Eclipe 1024mb RAM 并删除了我的 .Minecraft 文件夹。

Answer 1

recipeItems[0].length 是 6。但是 recipeItems[2] 及其后面只有五个元素。因此，您在 addRecipes 中的顶级循环是错误的。

您可能应该为此使用集合类型( vector 、列表、Array...)和迭代器，这将使代码更安全、更具可读性(IMO)。
