[PD] gemlist/spline_path issues

[Jeff Siegel]

Hi guys.

So I'm relatively new to PD, and right now I'm trying to make a set number
of discrete objects (20 of them) created along a spline path. In the
cityscape1 subpatch in the patch below, I've set up an array to be randomly
populated on a bang from the main patch screen. I'd like the objects in the
gemlist in the cityscape1 subpatch to use that array, via spline_path, to
generate each object's y-axis value. Obviously, how I've set it up is simply
creating a straight line of evenly placed circles, rather than conforming to
the path as set. What am I doing wrong, or is there another way to do this?
Thanks.
