我如何 select 一个随机数组，然后是该数组内的一个随机索引？

Question

;Sayings
friendly := ["hello there!", "Howdy!", "Greetings friend!", "hi there"]
helpful := ["x next to y and z", "this is helpful", "The sky is blue"]
other := ["where is my toaster", "do it", "just"]

;Categories
welcome := [[friendly][helpful][other]]

Numpad0::
    intotext(randomfromarray("friendly"),50,35,15)
    return

Numpad1::
    intotext(randomfromarray("helpful"),50,35,15)
    return

;Numpad2::
    ;Select a random saying from the welcome category.

intotext(whatisit,thekeydelay,introwait,outrowait)
{
    SetKeyDelay, thekeydelay
    Send, t
    Sleep, %introwait%  
    Send, %whatisit% 
    Sleep, %outrowait%
    Send, {enter}
}

randomfromarray(uniquepickof){
    return %uniquepickof%[random(1, %uniquepickof%.maxindex() )]
}

random(x, y){
   Random, var, %x%, %y%
   return var
}

谁能帮我弄清楚（对于 Numpad2::）如何 select 来自欢迎类别的随机谚语数组，然后 select 该（谚语）数组的随机索引？

我尝试抛出一些想法，但结果都只有 "t"，因为我没有 return 正确地选择（选择随机数组）[index] 值。

这就是我要做的工作：

;Sayings
friendly := ["hello there!", "Howdy!", "Greetings friend!", "hi there"]
helpful := ["x next to y and z", "this is helpful", "The sky is blue"]
other := ["where is my toaster", "do it", "just"]

;Categories
welcome := [friendly, helpful, other]

Random, randNumOne, 1, welcome.MaxIndex()

MsgBox % "Your random number is for array is: " . randNumOne

randArray := welcome[randNumOne]

Random, randNumTwo, 1, randArray.MaxIndex()

MsgBox %  "Your random Saying is " . randArray[randNumTwo]

为了简化，我删除了您的自定义函数，它实际上只是内置 Random 函数的包装器。我留下了 MsgBox，这样您就可以验证输出是随机的。

这是您的整个脚本，其中新的随机 select 功能分配给 Numpad2 按键：

;Sayings
friendly := ["hello there!", "Howdy!", "Greetings friend!", "hi there"]
helpful := ["x next to y and z", "this is helpful", "The sky is blue"]
other := ["where is my toaster", "do it", "just"]

;Categories
welcome := [friendly, helpful, other]

Numpad0::
    intotext(randomfromarray("friendly"),50,35,15)
    return

Numpad1::
    intotext(randomfromarray("helpful"),50,35,15)
    return

Numpad2::
    Random, randNumOne, 1, welcome.MaxIndex()

    MsgBox % "Your random number is for array is: " . randNumOne

    randArray := welcome[randNumOne]

    Random, randNumTwo, 1, randArray.MaxIndex()

    MsgBox %  "Your random Saying is " . randArray[randNumTwo]
    return

intotext(whatisit,thekeydelay,introwait,outrowait)
{
    SetKeyDelay, thekeydelayt
    Send, t
    Sleep, %introwait%  
    Send, %whatisit% 
    Sleep, %outrowait%
    Send, {enter}
}

randomfromarray(array)
{
    Random, rand, 1, array.MaxIndex()

    return array[rand]
}

我如何 select 一个随机数组，然后是该数组内的一个随机索引？

How do I select a random array, and then a random index inside THAT array?

arrays

random

arguments

autohotkey

return
