To add further to my "internet talking to myself" thread today...
This is what it takes to change a value on just one iteration. This just doesn't seem right that I have to employ the queue, and can't just plug the interpolate out directly into the conditional. You have to create a queue of all the vals that are being produced by something in an iterator, and then make a conditional statement based on one of the positions, so that you can flip a multiplexer that lets the "new" value pull through. To check the demo, hover cursor over an object, click on it, then move it up or down. That's all it does (so far). I would definitely like clarification on why I can't use "current index" with the "structure index member" in this scenario, and I have to use the interpolate in Loop to get all of the indices to render. (Now I have the horror of setting up feedback loops with this to "keep things where they were", and getting x movement going.) -George Toledo On Fri, Aug 13, 2010 at 11:17 AM, George Toledo <[email protected]> wrote: > Going further, this is what I have to do to actually iterate through the > index values in the "iterator question current index" and have it work > correctly. > > -Take an interpolation patch, set to external time, connect external time > to current position from iterator variables. > -Set start val to 0, set connect end value to iteration output of iterator > variables. > -Place interpolate in "loop" mode (not "none"). > > This just seems weird.
