Hi im making a drawing tool:
void setup() {
 size(300, 300);
 background(0);
 fill(random(0,255), random(0,255), random(0,255));
}



void draw() {
 stroke(255);
 strokeWeight(5);
 smooth();
 // Draw if mouse is pressed

 if (mousePressed) {
   line(pmouseX, pmouseY, mouseX, mouseY);
   
 }
}

Thats the code for it, but I wodered if there was a way to make what you have drawn fall down and go off screen after say 5 seconds, abit like this:

Drop [] drop;
int threshold = 20;
void setup(){
 size(400,400);
 drop = new Drop[100];
 for (int i = 0; i < drop.length; i++){
   drop[i] = new Drop(0,200+10);
 }
 ellipseMode(CENTER);
 smooth();
}
void draw(){
 background(0);
 for (int i = 0; i < drop.length; i++){
   drop[i].draw();
   drop[i].update();
 }
}
class Drop{
 float x,y;
 int timer;
 Drop(float x, float y){
   this.x = x;
   this.y = y;
   timer = 0;
 }
 void draw(){
   ellipse(x,y,5,5);
 }
 void update(){
   if(timer < 100)
timer++;
   else if (y < height+20)
y += 1.0;
 }
 void place(float x, float y){
   this.x = x;
   this.y = y;
   timer = 1;
 }
}
void mousePressed(){
 int item = -2;
 int items = 0;
 for (int i = 0; i < drop.length; i++){
   if (drop[i].y > height){
item = i;
   }  
   else {
items++;
   }
 }
 if (item > -1){
   drop[item].place(mouseX,mouseY);
 }
 if (items > threshold){
   for (int i = 0; i < drop.length; i++){
drop[i].timer = 500;
   }
 }
}

But instead of just dots falling I want what ive drawn to fall.

Im really new to this..
