hi!now every time circles intersect background color is changed
i wonder how to make the same happen but after n times circles touch
say when circles has intersected 3 times, change background colour
any ideas?
best, k

1. float diam = 100;
   boolean currentlyTouching;
   color bgColor = color(255);
    
   void setup() {
     size(500, 400);
     strokeWeight(5);
     noFill();
     smooth();
   }
    
   void draw() {
     background(bgColor);
    
     float x = width/2;
     float y = height/2;
    
     float d = dist(x, y, mouseX, mouseY);
    
     if (d < diam) {
       if (currentlyTouching == false) {
         bgColor = color(random(255), random(255), random(255));
       }
       currentlyTouching = true;
     } else {
       currentlyTouching = false;
     }
    
     stroke(255, 255, 0);
     ellipse(x, y, diam, diam);
    
     stroke(0, 255, 0);
     ellipse(mouseX, mouseY, diam, diam);
   }
