1,969 PointsWhenever the bird eats the frog and the game restarts, an error pops up saying that the object was destroyed.
Its really weird. The error is "MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object. GameState.EndGame () (at Assets/Prefabs/GameState.cs:81) GameState.Update () (at Assets/Prefabs/GameState.cs:47) ". Does anyone know what this means, and if so how to fix this?

That means those lines are written incorrectly. Please watch the videos and again. Plus write the code again. Make sure there are no typos.

using System.Collections;
public class Brick : MonoBehaviour {
public int maxHits;
public int timesHit;
private LevelManager levelManager;
// Use this for initialization
void Start () {
timesHit = 0;
levelManager = GameObject.FindObjectOfType<LevelManager> ();
}
// Update is called once per frame
void Update () {
}
void OnCollisionEnter2D(Collision2D col){
timesHit++;
if(timesHit >= maxHits){
Destroy (gameObject);
}
}
// TODO remove this method once we win
void SimulateWin (){
levelManager.LoadNextLevel ();
}
}

1,969 PointsI don't really know what to do with this. Besides, I've been trying to fix this for the past 2 hours. I've looked through the videos about 15 times now. The real problem is that the frog is completely gone. Could you please clarify what you mean?

1,969 Pointsyah, its not working. It says that everything on line 14 is incorrect.

31,009 Pointswell. I'm using 5.1 maybe it's because your using unity 5.2 the course is taught in unity 5.1. Maybe downgrade.
