Hello, I wonder whether you could help me with my issue?

I'm using the 'balls' example from 'http://www.learningprocessing.com/' :
http://www.learningprocessing.com/examples/chapter-10/example-10-2/

With oscP5 I receive 'integers' from SuperCollider. These values should be used to change the radial (size) of the balls made with the class. Now, I am struggling to do find a solution...

How could I do that?

And also how to I change an integer (received from SC) into a float (that is used in the class).

Any help appreciated, all the best, K
