请教一个关于变量储存的问题 - Project1

#=============================================================================
# 物品合成简易优化版 Ver 1.0
#-----------------------------------------------------------------------------
# By : RyanBern
#-----------------------------------------------------------------------------
# 功能介绍：
# 这是一个简单的物品合成系统，和论坛上原有的有所不同。在这个系统里面你可以
# 通过学习配方来获取某种道具的合成方法，也可以直接合成。有关数据存储我已经
# 改成了外部文件的形式，下面就说明一下如何使用。
#-----------------------------------------------------------------------------
# 使用方法：
# 1.有关数据编辑，在游戏根目录里面建立一个名为 Recipes.txt 的记事本，然后
# 再里面写下所有配方的内容，下面是一个例子表明如何书写一组完整的数据。
# <recipe=1>
# <product>kind=0,id=3</product>
# <ingredients>
# kind=0,id=1,number=2
# kind=0,id=2,number=2
# </ingredients>
# </recipe>
# 其中，第一行recipe=1表示这是ID为1的配方的数据，这里ID是从1开始的。
# 第二行是表示最终合成的物品，kind表示分类，道具为0，武器为1，防具为2；id
# 就是对应的ID
# 第三行是原料的设定，所有的材料都必须在<ingredients></ingredients>之间
# 每一行代表一种原料的分类，id，和数量，注意不要写重复了。
# 如果想再增加一条配方，则令起一行开一个<recipe>结点即可。
# 2.有关学习配方：
# $game_party.recipe_learn?(配方ID) 用于判断是否习得某一配方
# $game_party.learn_recipe(配方ID) 学习该ID的配方
# $game_party.forget_recipe(配方ID) 失去该ID的配方
# 3.有关场景调用：
# $scene = Scene_Craft.new 直接打开合成场景，配方为主角已有的配方
# $scene = Scene_Craft.new(0/1/2) 打开合成场景，配方为产品分类为i的配方(无论主角是否习得)
# $scene = Scene_Craft.new(3) 打开合成场景，配方为所有的配方
#-----------------------------------------------------------------------------
# 注意事项：
# 1.Recipes.txt里面的缩进不是必须的。
# 2.游戏发布时，可以删去Recipes.txt，不过建议在你的制作工程中保留一个副本
# 以便日后做出更改。
#-----------------------------------------------------------------------------
# 更新记录：
