Instantiate gameObject returns null?
Hi forum, I am new to unity and this is my first project.
I am trying to instantiate a gameObject and do something with it later.
public class spawnBase : MonoBehaviour {
public Transform baseSpawn;
public Transform baseSpawn;
// Update is called once per frame
void Start () {
GameObject temp= Instantiate(baseSpawn,new Vector2(spawnObject.position.x,0.73f),spawnObject.rotation)as GameObject;
int index = globalScript.getFreeQueue();
globalScript.setArray(index,temp);
if(temp==null){
Debug.Log("not supposed to be null");
}
temp.GetComponent<localVariables>().index = index; //returns error
}
error: NullReferenceException: Object reference not set to an instance of an object. So I found out that temp is indeed null. But the clone object shows up in both the camera and the hierarchy window. objectname(clone). So its both null and not null?
I have also try to instantiate with Quaternion.identity as the last parameter, but it gives the same error message.
Both of these are runtime errors.
What am I doing wrong here? Thanks for your time!
Are you sure it's not the Getcomponet call that is returning null? Can you post the full error message.
The object you are trying to instantiate is a Transform. You are trying to instantiate a Transform as GameObject which is not possible.
If baseSpawn is a Transform, you must instantiate (cast) it as a Transform. If you make the baseSpawn field to be of type GameObject, the code will work (you need to drag and drop the prefab in the editor again to re-establish the connection after changing the type)
public GameObject baseSpawn;
// Update is called once per frame
void Start () {
GameObject temp = Instantiate(baseSpawn) as GameObject;
will work, as will
public Transform baseSpawn;
// Update is called once per frame
void Start () {
Transform temp = Instantiate(baseSpawn) as Transform;
