What I did, I unchecked the Tick Marks of the Mash Renderer and Use Gravity in the Inspector and used below code before watching the Video and it worked fine. I don’t know if it is the Right approach but the code is shorter. Please advise
public class Dropper : MonoBehaviour
{
[SerializeField] float timeElapsed = 3;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
if (Time.time > timeElapsed){
GetComponent<MeshRenderer>().enabled = true;
GetComponent<Rigidbody>().useGravity = true;
}
}
}
