Subject:	Re: FLASH: Random Questions Without Repeating

It's not as easy in Flash as in Director! Something like the following
should work. I haven't tested it, so there may be typos or something
not syntactically correct, but the theory of it should be OK:

If you have 30 variables, question1 - question30, and you want to
display a random one in textfield <thisquestion>, then do this first
(actually I think Flash defaults a variable to 0 if you don't specify
otherwise, but for the sake of logic I left it in):

Set Variable: "nTimes" = 0 //how many questions have been
displayed

and then this every time you want to show a new question:

Set Variable: "duplicate" = true // just to initialize for
next line
Loop While (duplicate=true) // loop til new random
number found
Set Variable: "ranNum" = random(30)+1 // random number, 1-30
Set Variable: "duplicate" = false // another loop initializer
Set Variable: "checkthis" = 1 // also a loop initializer
(i want flash5 now!)
Loop While (checkthis < nTimes+1 and duplicate=false)
If (ranNum = eval("alreadyasked"&checkthis))
Set Variable: "duplicate" = true
End If
Set Variable: "checkthis" = checkthis+1
End Loop
End Loop
Set Variable: "nTimes" = nTimes + 1
Set Variable: "alreadyasked" &nTimes = ranNum // array of previously
selected numbers (like you suggested)
Set Variable: thisquestion = question&ranNum
