Grow a square shape

Question

Dear all:
I want to open and then close smoothly (slide) litle by litle
a square
vector shape. This is the code I use, but does not work.
repeat with h=1 to 200
sprite(2).height=sprite(2).height + h
end repeat
Can you help me?
Thank you

What? This won't do what you want at all. You were closer the
first time.
All this will do is move the sprite, not grow it. Also, as I
said, the
updateStage trick is kind of a hack, and can cause other
problems, like
slowing down the playback, and preventing all other scripts
from running.
(It may also interrupt sound playback if you've got any audio
going on.)
Sean's approach will probably work the best. The only thing
that's missing
is that you should have a frame script that keeps the
playhead looping on
one frame until the grow is finished. On the frame, just have
a script that
says:
on exitFrame
go the frame
end
Then alter Sean's script like so:
property spriteNum
property my
property _counter
on beginSprite me
my = sprite(spriteNum)
_counter = 0
end
on exitFrame me
if _counter < 200 then
_counter = counter + 1
my.height = my.height + 1
else go the frame + 1
end
Only difference is I added the command to go to the next
frame after the
grow is completed. (You could also go to a marker or a
specific frame or
execute any other command at this point.)
