Thanks for your quick responce David. I guess my example was a bad one but I will try to explain better. What I'm trying to do is for example I have 1circle that it attached to an osc~. A 2circle attached to a frequency modulation patch. A 3circle attached to another osc~ with a different frequency/tone. What I want is that as 2circle(frequency modulation) gets near 1circle(osc~) the frequency modulation patch interacts with 1circle's osc~ and as it moves away from 1circle and towards 3circle(osc~2), the frequency modulation stops interacting with 1circle and starts interacting with 3circle. I am using the TuioClient in order to recieve position data so yes I will definitly know the position of the objects. Is this something that can be done with pmpd or what other externals would you suggest me looking into. Thanks, Alain

Hi,

Well, first of all, I don't know the answer to your question, but what is it you are trying to achieve? I'm 99.9% that there is a better way to achieve what you want, without attaching the objects dynamically.

Second, attaching a [loadbang] to a [metro] won't do anything. A loadbang only bangs when you load up the patch, but in your case, the patch is already loaded, so nothing is going to happen. Probably what you really want to do is something different.

Third, to find out how close to objects are, you simply need to make an abstraction to measure the 3d distance between two points. Gem objects won't tell you their position, but that doesn't matter because you should already have their position, since somewhere in your patch something is sending coordinates into the Gem objects, telling them to move! Otherwise they would just be in the center of the screeen...

Maybe that helps a little?! Give us more info and we can probably help more.
