如何選擇一個隨機數組，然後在THAT數組中選擇一個隨機索引？

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 
} 

1. 有人可以幫我找出（用於NUMPAD2：:)如何從Welcome類隨機熟語陣列，然後選擇（說）陣列的隨機指標？

我試着拋出一些想法，但它們都是隻有「t」，因爲我沒有正確返回（pick random array）[index]值。

Answer 1

因此，這裏是我得到了什麼工作：

;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] 

爲了簡化，我刪掉了實際只是一個包裝您的自定義功能，內置Random功能。我離開了MsgBox，以便您可以驗證輸出是隨機的。

這是你分配給NUMPAD2按鍵新的隨機選擇功能完整的腳本：

;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] 
}
