I confuse how to put a function to a mouse click so if i click the mouse it will start produce the ball and checking the collision again. I tried timer function but it didnt work. Thank you so much before it.

here's my code sorry for the comment, just ignore it

Cheers

How about this?

void mousePressed () {
for (int i=0; i<balls.length; i++) {
balls[i] = new Ball(random(200,800),random(300,500), 60);
vels[i] = new PVector(random(-5.0,5.0), random(-5.0,5.0));
}
smallballs.clear();
testsmallballs.clear();
}
