出现的错误：

attempt to index field '?' (a nil value)
v[0]是直线的rgb，v[1] - v[4]是直线的x1,y1,x2,y2。
有人对如何从列表中获取每个值有任何建议吗？
Lua 的 table 构造函数以整数 1 开始默认键，使您的索引减一。想必，TI-Nspire也是如此。
v[0] 将是 nil，因此 v[0][0] 会导致运行时错误。 （在Lua 5.3.4中，我无法匹配你引用的确切错误消息。可能消息格式已更改。）
因此，使用 v[1][1] 代替 v[0][0]，依此类推。
我有这个列表和代码 (tldr):

出现的错误：
Line 6:
attempt to index field '?' (a nil value)
v[0]是直线的rgb，v[1] - v[4]是直线的x1,y1,x2,y2。
有人对如何从列表中获取每个值有任何建议吗？
Lua 的 table 构造函数以整数 1 开始默认键，使您的索引减一。想必，TI-Nspire也是如此。
v[0] 将是 nil，因此 v[0][0] 会导致运行时错误。 （在Lua 5.3.4中，我无法匹配你引用的确切错误消息。可能消息格式已更改。）
因此，使用 v[1][1] 代替 v[0][0]，依此类推。
