Can anyone help?  I am working on a basic game for an engineering class, but am running into difficulties.  I am trying to use the intersect function between two classes, one of which is an array for cats, another is a class for beer.  when the two objects (cats and beer) get too close, a spilled  beer image will be displayed. Any tips?  I've tried changing around the variables, but nothing seems to work.

boolean intersect (Cat b) {
    float distance = dist(cx,cy,mouseX,mouseY);
   
  if (distance < r/2) {
    return true;
 } else {
     return false;}
 }

boolean intersecting = intersect(cats,beer);
if (intersecting) {
  image(spilledbeer,beerx,beery);}
 

 }

Cats and Beer, i would love to know what kind of game that is going to be

thanks for the help, i'll give it a shot.  And because there is some interest, the game is very simple.  An array of cats randomly float around the screen, while you control an image of a Sierra Nevada Pale Ale bottle with the mouse to avoid hitting them.  Every ten seconds, another cat is drawn in.  If a cat hits the beer image, a spilled bottle will be displayed, and game over.  The title is "Save the beer from the stupid cats".  It's an homage to my wife's cats.  Anyways, having trouble with the intersection of the beer and the cats.  Hopefully i can get this working soon.
