I am experiencing difficulty parsing and efficiently getting data from my jitter system. I currently have 32 objects in a world and am trying to get the collision data out in a more manageable form (such as o dot). One difficulty that I am having is when I choose to output collision data my jitter program seems to drop frames (stutters) and becomes less fluid in drawing the animations. With fewer objects this does not occur however I am wondering if this has to do with available ram (and computer hardware) or if Max is the issue. (One last hypothesis of mine is that the slowdown is due to printing the dictionary data). My other difficulty has to do with how to parse the collision data as it is in Dictionary format. I am not too familiar with this however I have learned that goes something like this.

collisions -> dictionary, "object 1"_"object 2" -> dictionary, "position" "normal" "contacts" "duration" "impulse" "body1" "body2"

I am not sure how to parse this data without routing each individual permutation of collision objects (which will be 7 (for last dictionary parameters listed above) * 32 (# of objects) + 6 (# of walls of a cube) = 266 number of times I will have to utilize route). If someone has delt with these issues before I would greatly appreciate some feedback on how one might approach these problems.

Here is the portion of my patch that is giving me the most difficulty.
