update method

Implementation

void update(Size bounds) {
  // Update the position by adding the velocity.
  position += velocity;

  // If the particle was accelerated, gradually reduce its velocity to the default.
  if (wasAccelerated) {
    velocity = computeVelocity(velocity, defaultVelocity, 0.01);
    // If velocity has returned to default, reset the accelerated flag.
    if (velocity == defaultVelocity) {
      wasAccelerated = false;
    }
  }

  // Handle collisions with the screen boundaries.
  handleScreenBoundaries(bounds);

  // Update the visibility status of the particle.
  updateVisibility(bounds);
}
