" I guess the library (or Processing 1.2.1) contains a bug."
You guess wrong here. Most of the time, the bug is in the code of the user, even if a bug in library or Processing itself is not excluded.

In your case, you make a very common error: you make in setup() a local variable shadowing the global variable of same name, which disappears at the end of the function. So the global variable remains null. Just remove the type name in front of the variable usage in the init line.

Woops. That solved the problem. Thanks!

Hi guys, I'm really new to programming, and I'm having a simila error, but I think I'm not making the same mistake here.
I'm trying to run a .gif animation but I want to be able to jump from normal play mode (classic frame by frame) to a frame merge that will eventually leat to a black burnt screen; i'm using gifAnimation library.

here's the code I'm using as example, but I get the same java.lang.NullPointerException. I'm using processing 1.5 on Mac OsX Lion.

Thanks!

1. import gifAnimation.*;
   int c = 0;
   PImage[] allFrames = Gif.getPImages(this, "Felix_TwoLipTime_NoAudio_512kb.gif");
   
   
   
   void setup() {
   size (320, 240);
   frameRate(8);
   
   }
   
   void draw() {
   
   if (c<allFrames.length-1) {
     c++;} else {
       c=0;}
   if (mousePressed) {
     image (allFrames[c], 0, 0); } else {
     blend(allFrames[c], 0, 0, 320, 240, 0, 0, 320, 240, MULTIPLY);}
   }
   

Yes, that's a different error, but still a common one.
When you initialize global variables, this is run before setup() is called. But the path to data is defined only after setup() is run... So move the getPImages call inside setup().
