Hey guys.

I need some help with this code. I get the error of "cannot find anything named startX". I've substituted in floats and int, but I don't know what to do anymore...

class Missile {
  float endX;    // End X position
  float endY;    // End Y position
  float endvar;  // Line gradient
  float startX;  // Start of missile line
  float startY;  // Weight of the missle
 
color c;
  Missile(float init_endX, float init_endY,
          float init_endvar, float init_startX, float init_startY,
          color init_c) 
         {
endX = init_endX;
endY = init_endY;
endvar = init_endvar;
startX = init_startX;
startY = init_startY;
c = init_c;
}

void render() {
  noStroke();
  fill(c);
  line(startX, startY, endX, endY);
}

void update() {
 startX = (float)random(300, 500);
 endY = 0;
 endvar = (float)random(-2.0, 2.0);
 endX = startX;
 endY++;
 endX = endX + endvar;
 
}
} // class Missile
Missile randomMissile() {
  return new Missile(startX, 0, random(-2.0, 2.0), random (300, 500),
  random(0),
  color(random(0, 256),
        random(0, 256),
        random(0, 256))
  );
}
ArrayList<Missile> missilelist; // list in null initially

void setup() {
  size(700, 500);
  // creates and initially empty ArrayList of missile objects
  missilelist = new ArrayList<Missile>(); 
}

void draw() {
  background(255);
  // render and update all the balls
  for(Missile b : missilelist) {
    b.render();
    b.update();
  }
}
void mousePressed() {
  missilelist.add(randomMissile());
}
