Hi there,

I'm just starting to learn processing and now I think I could need your help, guys.

I defined a class called Circles and now I try to add some mouse functions.
For example all Circles of the class chance the color when the mouse is over.
But unfortunately i don't know how??? It is possible to do some mouse function on a whole class, at all?

I hope someone could please help me. I'm grateful for all replys and notes.

Thats my code now:

1. class Circles{
     float x,y;
     float groesse;
     float alph;
     float vx;
     float vy;
     float id;
     float ellColor;
     float gradient;
     float R, G, B;
   
       //constructor
     Circles(float _x, float _y, float _groesse, float _alph, float _vx, float _vy, int _id, float Rot, float Gruen, float Blau){
         x = _x;
         y = _y;
         groesse = _groesse;
         alph = _alph;
         vx = _vx;
         vy = _vy;
         id = _id;
         R = Rot; G = Gruen; B = Blau;
       }
   
       //methods
   void update(){
     int n = (height-100);
     int n2 = (width+600);
       x+=vx;
       y+=vy;
      
       if(x>n){
         vx--;
       }
       if(x<-5){
         vx++;
       }
       if(y>n){
         vy--;
       }
       if(y<-5){
         vy++;
       }
    }
       void ellColor(){
        fill(255,0,0);
          
         for(int i = 0; i < circles.length; i++){
            if(dist(x,y,circles[i].x, circles[i].y) < groesse*1.5 + circles[i].groesse*1.5){
              gradient = map(dist(x,y,circles[i].x, circles[i].y),groesse,groesse*2,250,150);
              fill(255,gradient);
            }
        }
       }
   
   void display(){
         fill(R,G,B, alph);
         noStroke();
         ellipse(x,y,groesse,groesse);
      }
    void cLines(){
        stroke(255,50);
        strokeWeight(.9);
        for(int i = 0; i < circles.length; i++){
            if(dist(x,y,circles[i].x, circles[i].y) < groesse*4 + circles[i].groesse*4){
              line(x,y,circles[i].x, circles[i].y);
            }
        }
       }
    }
