With the time it would take for me to understand your code, I could write my own
Wasn't it exactly his point? That is, verlet physics being relatively simple, writing your own system is affordable. Now it's clear for me that if you can have an already written library (with a consistent interface) that entirely suits your needs, well of course use it, don't be fool :)Anyway as I understand it, it was not meant to be used as is, it's just a code snippet, not a library.
