plethora flock 2d change boundary

Contributed Library Questions

Hello world,
I am new to processing and I hope someone out there can teach me a thing or two about the 'plethora flock2d' example.
I put the code underneath. Now I want to do 2 things
1. I would like to change the boundaries
so where in the code can I do that? I tried changing all the possible variables, did not succeed
2. I would also like to add straight lines inside the boundary box 'walls' as extra boundaries, can I do that? And how?
Thanks very much in advance,
Yasser
