I am playing around with the Processing example files, and they are very helpful and lots of fun. However, I am confused as to the location of the files that are used in these examples. For instance, there is the line
maskImg = loadImage("mask.jpg");
and I can't find the file mask.jpg anywhere on my computer. Is it online somewhere? If not, where is it?
I have put 2 cars on the screen and they are moving just fine. What I can't figure out is why they don't leave an image on the screen as they move? What makes them erase? I can't see any code--there's not much--that tells the program to erase the previous image. So I'm wondering why they erase. Maybe they don't erase at all, but I can't figure out why it acts how it does.
Any help here? This could be very simple, I think.
