Hi there,

What is the best way to smoothly scroll a large image. If I use a class like this for movement the screen updates in a very jerky way. Please help. Thanks


class Glider{
 float x,y;
 float glWidth;
 float glHeight;
 float speed;
 float yAccel;
 float yGrav = 0.01;
 float yVelo = 0;

 //Constructor
 Glider(float xpos, float ypos, float Wid, float Heig, float acc){
   x=xpos;
   y= ypos;
   glWidth = Wid;
   glHeight = Heig;
   yAccel = acc;
 }

 void move(){
   
  yAccel = yGrav;
  yVelo = yVelo + yAccel;  
   y = y + yVelo;
       
   if (y > 300) {
     yVelo = -yVelo ;
   }

   image(PersonImage, x,y, glWidth, glHeight);
 }
}
