How to limit number of bullets in shooting game?

kkesih

Hello,

I'm just learning processing and trying to create a very simple shooting game. I need to know how to fire bullets from the location of a mouse click to random positions, and limit the number of bullets to 10. What is the best way to approach this?

class Bullet {
 float px,py,vx,vy;
  Bullet(){
    px = mouseX;
    py = mouseY;
    float r = random(TWO_PI);
    vx = 5*cos(r);
    vy = 5*sin(r);
  }
  boolean draw(){
    px+=vx;
    py+=vy;
    ellipse(px,py,10,10);
    return(!(px>-20&&px<width+20&&py>-20&&px<height+20));
  }
}

ArrayList<Bullet> bullets = new ArrayList();

void setup(){
  size(440,440);
}

void draw(){
  background(0);
  for(int i=0;i<bullets.size();i++)if(bullets.get(i).draw())bullets.remove(i);
}

void mousePressed(){
  if(bullets.size()<10) bullets.add(new Bullet());
}
