Что за код?

  private static void setFlow(MeteorFlow flow, Point mouse) {
        for (int i = 0; i < flow.flow.length; i++) {
            Meteor meteor = flow.flow[i];
            Point point = meteor.getPoint();
            double dx = mouse.getX() - point.getX();
            double dy = mouse.getY() - point.getY();
            double speedX = rnd.nextDouble() * dx / 20 + dx / 100;  // speed = 0.01..0.05 od distance
            double speedY = rnd.nextDouble() * dy / 20 + dy / 100;  // speed = 0.01..0.05 od distance
            meteor.setSpeed(new Point(speedX, speedY));
        }
    }
