Hi,

I am new to processing. I have applied a circle packing algorithm on my processing project. and I have managed to do a mouseover effect on any circle - the circle size and colour will change. 

I am now trying to also alter the circle size and colour of surrounding circles that touches the corners of that particular circle that I have moused-over, unfortunately, I can only change the color of surrounding circles but not the size of the circles.

this is the step that I took.

1) hover on any circle

2) check for surrounding circles touches the hover circle

3) if touches increase the surrounding circle sizes and change color

4) redraw

I can retrieve the size of all the surrounding circles, but I am unable to change the size of the circles.

I would be most grateful if you could share with me how i can change the size of the surrounding circles prior to sending for redraw?

Attached is my code.

for(int i = circles.size()-1 ; i >= 0 ; i--){

            Circle c = getCircle(i);

            if(c.contains(mouseX,mouseY)){

                mouseHover(i);

               for(int j = circles.size()-1; j >= 0 ; j--){

                if(j != i){ 

                mc = getCircle(j);

                float rrr = (Integer)radius.get(i);

                    c.radius += 0.02;

                       if(rrr > 20 && rrr < 40){

                         if((int)c.radius >= rrr*1.7){

                            c.radius = rrr*1.6; 

                         }

                         else if((int)c.radius >= 90){

                            c.radius = 90; 

                         }

                       }else if(rrr >= 40 && rrr < 70){

                          if((int)c.radius >= rrr*1.5){

                             c.radius = rrr*1.5; 

                          }

                       }else if(rrr >= 70){

                          if((int)c.radius >= rrr*1.1){

                             c.radius = rrr*1.1; 

                          }

                       } else if (rrr <= 20){

                          c.radius += 0.02;

                          if((int)c.radius >= rrr*2.2){

                             c.radius = rrr*2.2;

                          } 

                       }

                   if(dist(c.x,c.y,mc.x,mc.y) <= c.radius + mc.radius){

                      mc.radius += 0.02;

                      if(mc.radius >= c.radius * 1.5){

                         mc.radius = c.radius * 1.5; 

                      }

                   }
