this script shows how to use repeat loops
to either play a series of sounds in a fixed list
or to play each new sound randomly drawn from list
*** see below for special note on repeat list

------------------------
random sounds
make 5 sound members named one, two...goat
put them is a list called ss
list is just a sequence of names separated by commas
pick a random number put it in variable called candy
got get that item from the master list
play it till it is done - get a new one
do the whole process 5 times (z is counter)
repeat while continues as long as soundbusy is true

on mouseUp
   ss="one,two,three,four,goat"
   repeat with z = 1 to 5
      candy=random(5)
      bb = item candy of ss

      if soundbusy(1) = false then
         sound(1).play(member bb)
      end if

      repeat while soundbusy(1)=true
      end repeat

   end repeat
end

---------------------loop
this one plays each sound in sequence from
the list

on mouseUp
   ss="one,two,three,four,goat"
   repeat with z = 1 to 5

      bb = item z of ss


      if soundbusy(1) = false then
         sound(1).play(member bb)
      end if

         repeat while soundbusy(1)=true
         end repeat
   end repeat

end


--------------------
**** special note on repeat loops
the scripts above are limited in their usefulness
repeat loops take over
they won't allow anything else
for example, they will not check mouse clicks 
you can accomplish a similar thing by using exit frames
 to simulate repeat loops by using a global variable as the counter

here is an example of playing a sequence
you could adopt the random one also
notice there is no repeat loop but it does the same thing
put this on frame script

on exitframe
   global z
   ss="one,two,three,four,goat"
   
    if soundbusy(1) = false then
        z = z+ 1  -- get the next counter
        -- only activates when one sound is done
        if z > 5 then z = 1 -- never more than in loop
        bb = item z of ss
        sound(1).play(member bb)
    end if
end
