Transcript

[BELL RINGING] Hello, and welcome back to part 2 of building your own Processing library in Java. Look, I'm working with Eclipse! I love eclipse! All of you will complain that I'm using Eclipse, and I don't care. I love Eclipse. It's one of the first places I learned to program, so it has a special place in my heart. So what I did in the previous p... Read More
