Unity - 实例化对象上的GetComponent返回Null

Question

I am trying to access a script on another gameobject that is instantiated in my script, and no matter what I do the script always returns null.

I instantiate the gameobject first by doing this.

asteroid = (GameObject)Instantiate(asteroidPrefab);

after that I try acessing its script by doing this:

AsteroidHandler handler = (AsteroidHandler)asteroid.GetComponent(typeof(AsteroidHandler));

To check whether or not the handler was set properly I did this:

if(handler == null){
    Debug.Log("Asteroid Handler is Null");
}else{
    Debug.Log("Asteroid Handler was setup properly");
}

The problem is this always does the null option. I have the AsteroidHandler script attached to the asteroidPrefab prefab, and when I Instantiate it, it Instantiates properly, as I see the asteroid on the screen. Still when I try accessing the AsteroidHandler script that is attatched to it, it seems to act like it isn't there;

I have tried a couple other methods to access AsteroidHandler but they all say its null:

AsteroidHandler handler = (AsteroidHandler)asteroid.GetComponent<AsteroidHandler>();

.

AsteroidHandler handler = (AsteroidHandler)asteroid.GetComponent(typeof(AsteroidHandler)) as Asteroid Handler;

I have looked at a couple other questions similar to mine, but none of the answers seem to help.

Any help would be appreciated.

Answer 1

Couldn't be easier,

add this code

asteroid = (GameObject)Instantiate(asteroidPrefab);
// add this...
asteroid.name = "Added test item";

run the program and wait until you see the "Added test item"

Check, do you ALSO see the "Asteroid Handler is Null"

Now, literally look in your Heirarchy for the scene, and find the object named Added test item

Look carefully at the Inspector, see what you see.
