Line and point attractors in Kangaroo

Hi there,

I downloaded this script a few years ago and cannot find it anywhere now! But anyway, I am trying to adapt it for a project I am working on but I am unable to make it work.

I will attach the original definition and my adapted one.

What I am trying to achieve is the movement of people being affected by certain site qualities. There is a top and bottom site area (box), at the top the lines are attracted to the outer edge and in the bottom they are repelled from the edge. I want to add extra effects like plumbing and birds. So the plumbing lines will retract at a slower rate than the edges and after a small delay I want a line to come in and start repelling the lines: like in a crowd of people when a pigeon fly’s in people move from it but move back once it’s gone.

Hope this makes sense!!! Any help will be much appreciated :)

I am currently using GH version 0.80010 and Kangaroo version 006 if that helps.

Matt
