Hi
I am very much a beginner with processing by all means. I really need help with this project where i am trying to flick across random positions on a filmstrip (which is essentially one long .jpg sliding across) by clicking the mouse. So far i have been able to get the strip moving but when i click it only shows the random sections for a single frame. i really want the effect of the strip moving then landing in the random spot while continuing to move.

this is what i have:

PImage img3;
PImage img2;
float y,x;
float speed=0.1;




//SETUP- ALL OF THE IMAGES
void setup(){


  size(678,598);
   img2= loadImage("FILM.jpg");//FILMSTRIP THAT WILL BE MOVING
   img3= loadImage("tv.png");//FRONT IMAGE BLOCKING FILMSTRIP

 
}

void draw(){
  background (0);
 
//MOVING THE FILMSTRIP
pushMatrix();
translate(x,y);
   x+=0.5;
  
image(img2,-23100,0);



popMatrix();
image(img3,0,0);

 
    }
   
    void mousePressed() {
     if(x> -23100) {
        pushMatrix();
      translate(x,y);
   x+=0.5;
  
       image(img2,x,0);
      
       x= random(-23100,678);
   
       popMatrix();
       image(img3,0,0);
      
     }
      
     
    }

ANY help would be so greatly appreciated!!!!!!
