How can I affect multiple sprites?

Question

Hi:
I am trying to affect multiple sprites when I roll over a
button. Basically it says:
on mouseEnter me
sprite(3).visibility = 1
sprite(4).visibility = 1
sprite(5).visibility = 1
end
on mouseLeave me
sprite(3).visibility = 0
sprite(4).visibility = 0
sprite(5).visibility = 0
end
How can I tell it to affect the 3 of them in one line? I
tried:
on mouseEnter me
sprite(3,4,5).visibility = 1
end
but this didn't work.
It is not an issue when its is only a few sprites...but I
might need to affect 10-15.
Any help would be great...
Thanks!
Rafael.

You could use a repeat loop where you make a list of the
sprite numbers
then go through that list
on mouseEnter me
repeat with i in [3,4,5]
sprite(i).visibility = 1
end repeat
end
OR
on mouseEnter me
mySprites=[3,4,5]
repeat with i in mySprites
sprite(i).visibility = 1
end repeat
end
That would be how to affect them directoly. You may not want
to use a
lot of tight repeat loops if there are large amounts of
these, since
that will tend to lock up Director until the repeat loop is
finished.
An easier way is to use sendAllSprites.
In the script that is on the sprites that you want to control
the
visibility of, add a custom handler like this:
on setVisible me, vVis
sprite(me.spriteNum).visible=vVis
end
Then, on your button, you would have code like this:
on mouseEnter me
sendAllSprites(#setVisible,1)
end
on mouseLeave me
sendAllSprites(#setVisible,0)
end
Now, when the mouse is over (or leaves) that sprite, any
sprite which
has that custom handler will turn its visibility on or off
