simple toggle on render


Hi all,

I'm just getting started with quartz composer and for my first trick, I thought I'd play with some flicker effects. In order to make this somewhat FPS independent I'm looking for a block or patch method to toggle a number (int or boolean) each time the view is rendered.

Suitable generators (e.g. LFO with square wave) seem to have periods in real time. An obvious fudge (using a 0 period or period less than the frame period) doesn't seem to give my intended effect... it correctly samples the specified waveform.

The other obvious approach -- using a Conditional or Logic block looped back on itself -- doesn't seem to be allowed as a valid patch. The same issue seems to preclude using a counter with reset caused by a chained conditional.

My first working attempt is a Counter followed by a Range and then taking the Rolled-Over Value.

Is there a better way? And more generally, is there a general buffer block to allow loops to be formed?

Thanks,
Daniel
