Hi Ilja,


The trick is to create a string that corresponds to the names of your MC's.

Pick a point in the string randomly, display that clip, then remove the

reference to that clip from the string by reconstructing it from all the

letters before and after the point you just picked. Here's some example code

i've used before:


15 MC's - mc_a, mc_b, mc_c...mc_o


Initilaize variables in frame 1 -


Comment: initialize

Set Variable: "rString" = "ABCDEFGHIJKLMNO"

Set Variable: "totalLength" = Length(rString)

Set Variable: "i" = 0

Stop



On (Release)

      Comment: check if anything already displayed. If it is, move it

offstage

      If (displayed gt "")

            Set Property (displayed, X Position) = -50

            Set Property (displayed, Y Position) = -50

      End If

      Comment: see if there are any clips left to display

      If (Length(rString) <= 0)

            Trace ("all have been displayed")

      Else

            Comment: pick a random position in 'rString'

            Set Variable: "rPos" = Random(Length(rString)) + 1

            Comment: reference the clip by the letter at that position in

the string

            Set Variable: "nextTarget" = "mc_" & Substring(rString, rPos,1)

            Comment: move movie clip to the centre of the screen

            Set Property (nextTarget, X Position) = 275

            Set Property (nextTarget, Y Position) = 200

            Comment: rebuild 'rString' with all the letters before and after

'rPos', but not 'rPos' itself.

            Set Variable: "rString" = Substring(rString, 1, rPos-1) &

Substring(rString, rPos+1)

            Comment: store the name of the MC currently displayed

            Set Variable: "displayed" = nextTarget

      End If

End On
