Grasshopper to Rhino Live Update

Hey,

I am looking for a way to control numerous points within rhino, created through grasshopper which is influenced by various factors. The points move in real time through the kangaroo plugin, currently using Uforce.

The situation is set up so that two points move away from each other in opposite directions, once the distance between them reaches a value, then the vector influencing the points is switched to another vector, thus moving the points back towards each other.

My current problem is that once the points reach a set distance, grasshopper appears to be not update, thus doesn’t realise such has occurred. Any ideas how to fix this? Simply how do I get grasshopper to recognize the distance is changing in Rhino? Thanks.
