Re: FLASH: Random Questions Without Repeating

[Nathan Dicken]

Hi Paul,


Here's a technique that you could use - esentially you build a string

"list" to hold values for your questions and you use and take away values

from that list.  The example below uses a list of 10 questions (you have

30) for your reference.  The digits variable is used for the string length

of your largest number (e.g. 10 - 2 digits).


Set Variable: "qList" = "01020304050607080910"

Set Variable: "digits" = "2"

Loop While (length(qList) > 0)

      Set Variable: "rValue" = random( length(qList) / digits ) + 1

      Set Variable: "qValue" = int(subString( qList,

((rValue*digits)-(digits-1)), digits ))

      Comment: act upon this qValue, or...

      Comment: create a new random list with it in non-integer form...

      Comment: ---------------------------------------

      Comment: finally, reform the "qList"...

      Set Variable: "prevList" = subString( qList, 1, ((rValue-1)*digits) )

      Set Variable: "postList" = subString( qList, ( ((rValue+1)*digits) -

(digits-1)), (length(qList)-(rValue*digits)) )

      Set Variable: "qList" = prevList & postList

End Loop


Try this out  - it should resemble more like how you'd do it in Director.
