java.lang.NullPointerException
Mar 17th, 2007, 7:34pm  
Hi there!

Someone knows a way to read a filename on the sketch folder and then change it? I'm playing in loop a quicktime movie from the sketch folder, but when I try to create another movie via moviemaker (from a web cam, to overwrite the first one), it says java.lang.NullPointerException (because they have the same name, I presume). Maybe a solution could be, once the webcam file has been created, to change its name and then read the file from processing.

Any suggestions?

When ever exporting a file I use this few lines to get an unique filename based on date and time.

Code:

Date now = new java.util.Date();
SimpleDateFormat formatter = new SimpleDateFormat("yyyy MM dd HH:mm:ss");
String filename = formatter.format(now)+".mov";

Great piece of code! But the question remains: I did a little program to create a movie with current HH_mm_ss, but how recall the produced movie back in processing? Updating the values of the filename of the imported movie? Reading the filenames from the sketch folder?...

I´m new on processing and feel a bit confused about the way to proceed.

Thanks in advance.
