I'm saving the run number in a file:

int runNo;
void loadRunNo() {
  byte loadedRunNo[] = loadBytes(”runNo.dat”);
  runNo=(loadedRunNo[0] << 24)
    + ((loadedRunNo[1] & 0xFF) << 16)
    + ((loadedRunNo[2] & 0xFF) <>> 24),
  (byte)(runNo >>> 16),
  (byte)(runNo >>> 8),
  (byte)runNo};
  saveBytes(”runNo.dat”, toSaveRunNo);
  println(”run #”+runNo);
}

DecimalFormat df5E = new DecimalFormat(”00000?);
void keyPressed() {
  if(key == ’s’ ){
    saveFrame(”shots/sketchname-run-”+df5E.format(runNo)+”-shot-######.png”);
  }
}

and in setup(): loadRunNo();

Oops. (forgot the file extension).

saveFrame(””name_of_sketch-”+year()+month()+day()+hour()+minute()+second()+”.png”);

I also use a timestamp but with Processing code only (as SimpleDateFormat is more Java. Thanks for the tip.). So for those not yet comfortable with Java:

saveFrame(“”name_of_sketch-”+year()+month()+day()+hour()+minute()+second());

Hey, that’s a great idea.

Thanks!

I use the timestamp to get unique filenames:

Date dt = new Date();
SimpleDateFormat df = new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss.S”);
saveFrame(“name_of_sketch-”+df.format(dt)+”.png”);
