does any1 know how i can stop the rain by using a mousepressed function. the one i have done below doesnt seem to work. any suggestions????????

int numRains=100;

Rain [] rn = new Rain [numRains]; //arrange an array of droplets
 
void setup ()
{
 size (600,600);
 smooth ();
 noStroke ();
 
   for (int i=0; i<rn.length; i++)   {
   rn [i]= new Rain (random(width),10,random(width/200),random(1,width/40));
 }
}
void draw ()
{
 fill (0,15);
 background(0);
 for (int i=0; i<rn.length; i++){
   fill (255);
   rn[i].move ();
   rn[i].display ();
 }
}
class Rain
{
 float x,y;
 float diameter;
 float speed;
 int direction=1;  

 Rain (float xpos, float ypos, float dia, float sp)
 {
   x=xpos;
   y=ypos;
   diameter=dia;
   speed=sp;
 }

 void move () {

   y +=(speed * direction);
   if ((y>(height-diameter/2)) || (y<diameter/2)){
     y=0;
     /*
//this is good but only when the mouse is held down!
     if (mousePressed){
      y=height;
      }
      */
   }
 }

 void display() // draws the spot to the display
 {
   for (int i=0; i<15; i++){
     pushMatrix();
     translate (x,y+(i*2.5));  
     fill(25*i);
     ellipse (0,0,diameter,diameter);
     popMatrix();
   }
 }
//this is the bit that doesnt work!
 void mousePressed(){
   y +=(speed * direction);

   if ((y>(height-diameter/2)) || (y<diameter/2)){
     y=height;
   }
 }
}

thankyou however this process stops the rain entirely, i was hoping to be able to achieve a gradual stop as is possible by using
if (mousePressed){
y=height;
}
the problem is that you have to hold the mouse for this to work so is it possible to use this somehow in a mousepressed function?
