Not sure if I missed where this was accounted for in the sample code. What I did on my end to stop it was to add the following…
inside the Ball class…
private bool isPlaying = false;
then in Update below the hasStarted = true; line I added
if (!isPlaying) {
this.rigidbody2D.velocity = new Vector2 (2f, 10f);
}
isPlaying = true;
This solved it for me but I am unsure if that is A) the best way and B) if this was addressed by you and I missed it.
