here i have loop of 12 images, 0..12, 0..12
how do you change that it move forward then backwards?
i want to scrub through sequence with noise function

1. int numFrames = 12;  // The number of frames in the animation
   int frame = 0;
   PImage[] images = new PImage[numFrames];
      
   void setup() {
     size(640, 360);
     frameRate(24);
    
     for (int i = 0; i < numFrames; i++) {
     String imageName = "PT_anim" + nf(i, 4) + ".gif";
     images[i] = loadImage(imageName);
     }
   }
    
   void draw() {
     background(0);
     frame = (frame+1) % numFrames;  // Use % to cycle through frames
     int offset = 0;
     imageMode(CENTER);
    image(images[(frame+offset) % numFrames], width/2, height/2);
       offset+=1;
   }
