Null Reference Exception transform position y
Hi, Unity Answers Heroes! I am getting a Null Reference Exception, and although it might be simple to solve for most, any help would be great! Here is the code:
private GameObject leftAsteroid = null;
private GameObject middleAsteroid = null;
private GameObject rightAsteroid = null;
// Update is called once per frame
void Update () {
countdown -= Time.deltaTime;
if (countdown == -1.0f) {
leftAsteroid = Instantiate (Asteroid, Asteroid1);
middleAsteroid = Instantiate (Asteroid, Asteroid2);
rightAsteroid = Instantiate (Asteroid, Asteroid3);
}
//System.NullReferenceException error on the next line
if(leftAsteroid.transform.position.y <= -2.0f){
//code here
}
hi; change and try those lines like this :
leftAsteroid = Instantiate(Asteroid, Asteroid1) as GameObject;
Thank you very much for your help! With both tips from you and Positive7, it seems to be working!
Because of the countdown leftasteroid is not spawned yet so it is null.
if (leftAsteroid != null && leftAsteroid.transform.position.y <= -2.0f) Debug.Log("OK!");
