// Example 20-2: Doorbell with Sonia

// A Class to describe a "doorbell" (really a button)
class Doorbell {
  // Location and size
  float x;
  float y;
  float r;
  
  // Create the doorbell
  Doorbell (float x_, float y_, float r_) {
    x = x_;
    y = y_;
    r = r_;
  }
  
  // Is a point inside the doorbell? (used for mouse rollover, etc.)
  boolean contains(float mx, float my) {
    if (dist(mx,my,x,y) < r) {
      return true;
    } else {
      return false;
    }
  }
  
  // Show the doorbell (hardcoded colors, could be improved)
  void display(float mx, float my) {
    if (contains(mx,my)) {
      fill(100);
    } else {
      fill(175);
    }
    stroke(0);
    ellipse(x,y,r,r);
  }
