Ok so I am relatively new to Processing. I've been taking a class that focuses on it all semester and right now I'm working on the final project. In my sketch I use the Procontroll library with Processing to use an xbox 360 controller as the input device.

The controller works fine and I have all the buttons set up but I'm having a problem with the functionality of my other code, governing how the game itself should run.

At this point, my addNewButton function works, because on start up it does highlight a button that it wants me to copy. However, it doesn't seem to be turning it over to me to copy it after that, and when I copy it, nothing happens. If anyone could take a look at my code and help me out with what I need to change/what I am missing, that would be much appreciated.

Thanks.
