Hello people. I am new to Unity and been trying to write a code for my first game. Almost everything was done but this notification poped out:

“NullReferenceException: Object reference not set to an instance of an object
GameHelper.Update () (at Assets/Scripts/GameHelper.cs:44)”

I know there are many different questions that had been asked about the same topic, but I couldn’t find answer for mine. Any help would be much appreciated!

Here is my cod:

42 if (SelectedBirdHelper != null)
43   {  
44    SelectedBirdHelper.GetComponent<Rigidbody2D>().isKinematic = false;
45     SelectedBirdHelper.GetComponent<Rigidbody2D>().AddForceAtPosition(
46     SelectedBirdHelper.transform.right* 1000,
47      SelectedBirdHelper.StartPosition

Check if gameobject “SelectedBirdHelper” has “Rigidbody2D” attached with it or not. Maybe it is not attached which is causing null reference error.

In my case GameBirdHelper is an c# script which refers to my RedBird sprite, which has a Rigidbody2D.
