Re: FLASH: Random Questions Without Repeating

[Helen Triolo]

(Third post today that's been sitting in my sent box for over an hour

without appearing on the list... have I wagged my chin 3 times too

many?)


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
