Creating Triggered Smooth Envelopes



Hello everyone - I'm trying to recode a little 'Pixel Invaders' patch I built
for Isadora within Quartz Composer, and I have the basics done. Here's what it
looks like at the moment:

http://www.la-va.org/momo/uploads/pixel_inv_color_depth.qtz

Right now I have the cubes winking in and out of existence via the 'enable' on
the cube itself. I'd also like to affect te depth: for example, when I randomly
receive a trigger to send an 'enable' command, I'd like to send a slow
progression from 0 to 1 to the 'depth' property on the same cube. I'd like to
then send a 1 to 1 before it gets winked out by unchecking the 'enable'
property.

I've been trying to trigger an Interpolation, and switch it from going up to
going down via a 'toggle' custom macro along with some javascript, but the
interpolation patches don't seem to re-trigger, and I still need to read the
depth before turning each cube off. If anyone wants to take a look and give me
any suggestions on implementing this feature (as well as general tips for
cleaner building) it would be most appreciated!

Thanks for making this a burgeoning community, everyone.

Cheers,
Surya
