Lua 如何修复此错误：“quot；尝试索引？（一个数值）“；

我想使

当前_question

变量从

questions

表中返回一个随机问题，但它给了我一个错误；“尝试索引？（数值）”

您需要告诉解释器

Q..math.random（1,10）

是一个如下字符串：

local questions={
    EN={
        Q1={"",""},
        Q2={"",""},
        Q3={"",""},
        Q4={"",""},
        Q5={"",""},
        Q6={"",""},
        Q7={"",""},
        Q8={"",""},
        Q9={"",""},
        Q10={"",""}
    },
    BR={
        Q1={"",""},
        Q2={"",""},
        Q3={"",""},
        Q4={"",""},
        Q5={"",""},
        Q6={"",""},
        Q7={"",""},
        Q8={"",""},
        Q9={"",""},
        Q10={"",""}
    },
    TR={
        Q1={"",""},
        Q2={"",""},
        Q3={"",""},
        Q4={"",""},
        Q5={"",""},
        Q6={"",""},
        Q7={"",""},
        Q8={"",""},
        Q9={"",""},
        Q10={"",""}
    }
}
local current_question = questions.EN.Q..math.random(1,10)[1]

---

最好将

Q

作为一个数组。

local current_question = questions.EN["Q"..math.random(1,10)][1]
