hello,

iam pretty new to OOP with processing and i dont find a mistake in my code =/
it complies correctly but nothing is drawn

1. 
   Ball myBall;
   
   
   void setup() {
     size(1000, 1000);
     smooth();
     myBall = new Ball(200, 500, 200, 200, 1);
   }
   
   void draw() {
     background(255);
   
     myBall.display();
     myBall.movement();
   }
2. class Ball {
     float x;
     float y;
     float w;
     float h;
     float speed;
   
     Ball(float tempX, float tempY, float tempW, float tempH, float tempSpeed) {
   
       tempX  =  x;
       tempY  =  y;
       tempW  =  w;
       tempH  =  h;
       tempSpeed  =  speed;
     }
   
     void movement() {
       x = x + speed;
       if (x>=width) {
         x = x * -1;
       }
     }
   
     void display() {
   
       ellipse(x, y, w, h);
     }
   }
