FLASH: random tones using an array?

[Bob Shuster]

I have a current Flash 4 project where a funky background loop is 

playing.  As four bullet points animate in (this happens repeatedly 

with different text!), they are accompanied by a musical tone that 

complements the underlying track.  I have it set up currently so that 

four random tones are picked from a set of five.  Here's the code I 

used:


Begin Tell Target ("tone" & Random (4))

       Go to and Play ("start")

End Tell Target


where there are individual movie clips on the timeline named "tone0" 

through "tone4".  Each MC obviously has a stop on its first frame, 

and "start" plays the tone and parks it back at the first frame when 

through.


This works great - however it seems to repeat notes quite a bit more 

than I'd like!  What I'd like to do is this:  I'd still like it to be 

four random notes out of five choices, *but* once a note is played in 

a particular four-note sequence, I'd like it to be removed as a 

choice until the end of that sequence.


i.e.:

note one  - choose one tone randomly out of five and remove this tone 

from future consideration

note two - choose one tone randomly out of the remaining four and 

remove this tone from future consideration

note three - choose one tone randomly out of the remaining three and 

remove this tone from future consideration


I think you get the idea!  I seem to recall from my elementary C and 

Basic programming courses (of more than 15 years past!) that I will 

probably need to use an array somehow to do this?  It's a vague 

recollection at best, and I don't have the foggiest idea of how to go 

about setting something like this up!


Anyone have any suggestions?  It needs to be Flash 4 for this 

project, but I'm sure if there's a simpler Flash 5 solution, someone 

will benefit from it!  :)   Thanks very much - this list rocks!    -
