labels to break/continue nested loops
Oct 1st, 2007, 2:57pm  
Hello everybody,

I'm using nested loops and whish I could use labels to break/continue through more than one nested level, but Processing doesn't recognize my labels and doesn't process the loops at all. It says : Invalid type:22.

Doesn't Processing support labels at all?

Here is the kind of code I would like to execute without getting an error (it's just a stupid example) :

firstLoop:
for (int i = 0; i < 10; i++) {
 for (int j = 0; j < 10; j++) {
   if ((i+j) % 5 != 0) continue firstLoop;
   System.out.println(i + " " + j);
 }
}

Thank you.

hi nicolas,

I've had the same problem. The error message seems to be thrown by the processing preprocessor. I've tried your code in a processing sketch in eclipse, and it works as expected.

Maybe we should report a bug for this one?
