Nov 17th, 2005, 8:13pm   How can I make this work? essentially I need the equivalent of the flash eval command but i don't see an equivalent in processing where framemask are Pimages defined at the start of the sketch. Code: for (int i=totalFrames; i > 1; i--) { "framemask" + i = "framemask" + (i-1).get(); } cheers niall

You'll need something like this: Code: PImage[] framemask; void setup() { ... framemask=new PImage[totalFrames]; for(int i=0;i<totalFrames;i++) { framemask[i]=loadImage(..); // or however you're creating the images } } void draw() { for(int i=totalFrames;i>1;i--) { framemask[i]=framemask[i-1]; } }
