Hi,
I'm new to PD and trying to use boids
(http://puredata.info/community/projects/software/boids) with GEM
(http://puredata.info/community/projects/software/gem).
The example boids2d-help.pd (attached) that comes with boids is almost
what I need, but it renders each boids result in a separate pd subpatch;
in pd gem_example a route object is used to route each result of boids
to a separate subpatch pd boid which takes care of the gem rendering.
Is there a way to send the results of boids to one subpatch that would
take care of all the rendering no matter how many boids results there
are ? This would allow me to fluctuate the number of boids without
having to create and attach new subpatches.
Any help is highly appreciated.
Best,
--

#X text -191 126 Based on Simon Fraser's implementation of Craig Reynolds'
Boids algorithm. Boids is free for non-commercial use;
#X text -191 159 Boids is a bird flight and animal flock simulator.
It is based on the same algorithm which was used in Jurassic Park for
the herding dinosaurs.;
#X text -191 208 Boids takes an integer argument which is the number
of boids. Each time Boids receives a bang \, it calculates and outputs
the new positions of the boids. The output consists of thew coordiantes
for each boid \, the number and type depending on the mode.;
#X text -190 282 The flight parameters can be changed with messages.
Use the 'dump' message to output a list of the current parameter settings.
