Hey guys,

On my way to university i wrote a little pattern program, which i want to be able to be configured with a GUI later on. But atm i am stuck on the speed paramater. As soon as i want to change speed settings inside my integer the whole progress isn't working anymore.

Here's the Code:

1. int x = 0;
   int y = 0;
   int speed = 40;
   int versatz = 5;
   
   
   void setup() {
     size (600, 600);
     smooth();
     background (80);
     noStroke();
   }
   
   void draw () {
    
     x = x + speed;
    
     fill (random(255), random(255), random (255), 100);
     ellipse (x, y , 40, 40);
    
     if (x >= width) {
       speed = speed * -1;
       y = y + versatz;
     }
       if (x <= 0) {
         speed = speed * -1;
         y = y + versatz;
     }
   
   if (y >= height) {
     versatz = versatz * -1;
     save("picture1.tif");
    
   }
   
   if (y <= 0) {
     versatz = versatz * -1;
   
   }
   
   }
