I'm not sure I understand your question, but supposing your frame numbers were placed in a list it might look like:

lFrames = [10, 12, 14, 16, 18, 20]

Then you could choose one of those items like James outlined. In order to not repeat the number you would remove it from the list

Let's imagine that your song markers are at frames 7, 14 and 35 (I've deliberately chosen frames which are not consecutive). You could create a list of frame numbers:

vSongFrames = [7, 14, 35]

The behavior on your Random button could look like this:

on mouseUp()

vSongFrames = [7, 14, 35] -- <HARD-CODED>

vSongCount = vSongFrames.count

vRandomSong = random(vSongCount)

vRandomFrame = vSongFrames[vRandomSong]

go vRandomFrame

end mouseUp

What does this do? It stores all your data concerning the frames that you could jump to in one place. If you change the frame numbers, or the number of songs, you make that change in just one place. In the next 4 lines, the code:

Calculates how many songs you have, using the list of frame numbers as a guide
Chooses one of those songs at random
Works out which frame that song starts on
Jumps to that frame

It's not normally a good idea to use hard-coded frame numbers. You might decide to add frames or move the markers in the Score. If you did that, the behavior would no longer work. It would be better to use frame labels...

vSongFrames = ["Name of marker for first song", "Second song", "Third song"]

... where the strings you use in the list are identical to the names of the markers in your movie. You would still be hard-coding data, but that data is less likely to change. Assuming that the marker label at frame 14 is "Second Song" then the commands...

go 14

-- AND

go "Second Song"

... have exactly the same effect.

You can use random() to choose a random number. If you have 17 song titles, then you could use:

vRandomSongNumber = random(17)

Suppose your other buttons do something like this:

on mouseUp()

PlaySong(3) -- or whatever system you use to decide which song to play

end mouseUp

Your random button could do this:

on mouseUp()

vRandomSongNumber = random(17) -- or however many songs there are to choose from

PlaySong(vRandomSongNumber)

end mouseUp

Does that help?

you can use the random() method

for example:

-- behavior script attached to your 'random' button

on mouseUp me

i = 120 -- number of songs

rnd = random(120)

sound(1).play(member("karaokeX"))

end

without more information on how you have things configured there's really no way to help.

Hiya! I am creating a karaoke product using Director 11.5 and in the main menu, i wanted to add the option of for the user to click on a button named 'Random'.
