关于存读档和SetVariable的几个问题，感谢解答！

u8830

这里是代码小白。
同类帖子我去看过了，但是并没有解决我的问题。
用init python 生成的class和list
用define 定义的数值变量 a
先是在screen 用 SetVariable修改过
之后又在label 中 用 $  修改过 a
保存，关闭游戏后再读档，数据就还原成初始值
看了有人使用default，然而我这里用了就报错。

另外SetVariable 不知道是不是对定义的变量有什么要求
我这里的问题是
使用SetVariable 可以修改 define 的变量 c
但是 $ 的变量d却不行（然而我看别人的演示是可以的）


以及，我 define c = 10 但是在 使用SetVariable（“c”,c+1）时，它似乎将c+1当作字符赋给c，
莫非它对变量命名也有要求吗？翻文档似乎没有讲

是生成npc，存读档用的是这个帖子里的大佬代码。
每次重启，之前存档生成的npc全都没有了。

然后下面就是我生成角色的代码。（不太会贴）
字符类修改似乎重新读档还能保存，但是数值类每次都会还原

还有就是游戏开始分配技能点
昨天SetVariable似乎一直把后面的变量当成字符，然而我今天试试又正常了

但是每次关闭游戏再读档后，原先的数值又恢复成class Player设置的数值。

一言以蔽之，define是存常量的，就是不会变的量。
default是存变量的，你这个需要存上变化，必须用default。

谢谢解答，但是我要改变的是class 里面的数值，像生成npc那个，我default 生成列表存数据似乎也没用
