i am trying to store the coordinates of each krosnja object so that i can use them, but what i get is coordinates for all 10 objects i initiated. i don't know how can i separate them and compare the coordinates later. what i am trying to do is to compare the x,y from k[0] object and k[1...etc].
like : dist(x(k[0]), y(k[0]), x1(k[1]), y1(k[1])

if someone can help that would be great.

thanks!

int currentk =0;
int numb = 10;
int xmos, ymos;


krosnja[] k = new krosnja[numb];
//float[]x = new float[numb];
//float[]y = new float[numb];


void setup(){

 size(1000,600);
 background(255);
 smooth();
 frameRate(25);
 stroke(0);
 strokeWeight(0.7);
 for (int i =0; i < numb; i++){
   k[i] = new krosnja();
   k[i].kros(random(width), random(height), random(3));

 }
}

void draw(){
 //if (keyCode == UP){
 for(int i = 0; i<numb; i++){
   k[i].crtaj();
 }
}  

void mousePressed(){

 xmos = mouseX;
 ymos = mouseY;
 k[currentk].kros(xmos, ymos, random(3));
 currentk++;

 if (currentk >= numb){
   currentk = 0;
 }
}
class krosnja{

 float xa, ya, step, stepx, stepy;
 float[]x = new float[numb];
 float[]y = new float[numb];
 float[][]xy = {
   x,y    };
 float di;
 int x1, y1, x2, y2;


 void kros(float xxx, float yyy, float stp){
   xa = xxx;
   ya = yyy;
   step = stp;
 }


 void crtaj(){
   stepx = step;
   stepy = step;    
   point(xa,ya);

   xa=xa+stepx*random(-1,1);
   ya=ya+stepy*random(-1,1);    


   if (xa > width-50){
     stepx = -step;
     xa = width-50;
   }
   else
     if (xa < 0){
       xa = 10;
       stepx = step;
     }
     else
       if (ya > height -50){
         ya = height - 50;
         stepy = -step;
       }  
       else    
         if (ya < 0){
         ya = 10;
         stepy = step;
       }
 }
}

thanks a lot for the help!

i should read the manuals more thoroughly.
