I have a minim error that says:

==== JavaSound Minim Error ====
==== Don't know the ID3 code TBPM

What does or could this mean? I haven't done anything besides adding two new mp3 files (same kind of file I was using before).

I'm making an image button (with a transparent-background png) that constantly moves to random locations along with scaling to random sizes. When the user clicks on its non-transparent area, a function will be called.

What is a good way to check the bounds for this?

If I want to write

1. File f = new File (dataPath("file.txt"));
2. if (!f.exists()) {
       print("no file");
   }
   

I have it currently at the top/blank space, but when I check whether or not it exists it always says it doesn't (I have everything correctly named in the correct folder). If I define it inside the setup() method, I get a null pointer exception.

Where should I write it?
