Unity 3D按标签查找对象

Question

I have gameobject with tag "Player" assigned to it and try to find it via С# script:

private GameObject player1;

void Srart(){

   player1 = GameObject.FindGameObjectWithTag("Player");
   if (player1 == null)
      Debug.LogError ("Object with player tag had not been found!");
}

void Update(){

    Debug.Log (player1.name);
}

The problem is that NullReferenceException is thrown in Update() function, but LogError message is not. That means that my object was succesfully found by tag. But somehow it wasn't, because player1 in update function is equal to null. So why do i have this error?

Answer 1

You have a spelling error.

Change void Srart() to void Start() .

Check out http://docs.unity3d.com/ScriptReference/MonoBehaviour.Start.html and other MonoBehaviour methods -- spelling is crucial!
