it's still doing the same basic thing.. i have an audio clip to let me know when the impulse is firing off.. but i can hear that the tolerance is still working as the sound turns off while in the acceptable range so it's working. this is what it looks like:

It still does the same back and forth never getting closer to the target. there has to be some way to reduce the impulse value drastically faster than a steady downward slow (which is what you get when you simply apply an impulse value based on distance difference)
the "tollernace" var is just a value set to i think 25 right now.. mostly just so i could hear the pause in audio triggering.. but it doesn't make any noticable difference if i change it to a tighter value like 5.. but also it actually has no effect if i make it 100 either..
I've noticed also that friction doesn't seem make any difference either.. which is odd. i'd have thought friction would fight impulse.. or at least hinder it's effectiveness.
