How can I assign references to GameObjects through a script?
For context, a little info about my game. When I press a key, the character in my game (an iteration of the Player Prefab) is supposed to send out an oblong child object (absorberPrefab), after which the player prefab is destroyed.
var absorbTransform = Instantiate (absorberPrefab) as Transform;
absorbTransform.position = transform.position;
Destroy (gameObject);
If this object collides with an enemy, the player gains control of the enemy by the enemy gaining the controller scripts.
public class BasicEnemyScript : MonoBehaviour {
void OnTriggerEnter2D (Collider2D player1Collider) {
AbsorberScript absorber = player1Collider.gameObject.GetComponent<AbsorberScript> ();
print ("hit");
gameObject.AddComponent<Player1> ();
}
}
If it misses, another instance of the player is instantly created.
My problem is that I have a camera following script with a variable
public Controller2D target;
which I normally have to so assign to my player gameObject via drag-and-drop in the inspector.
However, if I'm controlling new gameObjects or creating new instances of the Player prefab, I need to a way to assign the camera to follow these during runtime. How can I assign these variables during runtime?
Similarly, is there a way I can create scripts or components so that they will always take in the same variable references automatically, no matter what they're assigned to (eg. a camera script that will always target the current instance of the player prefab)?
Thank you!

Thanks for the reply! In order to send out the oblong prefab, the script that controls it needs to take in a reference to a prefab, in this case called "Absorber1". When I try
public GameObject absorber1Prefab;
void Awake () {
absorber1Prefab = GameObject.Find ("Absorber1");
}
void Update () {
Instantiate (absorber1Prefab, gameObject.transform.position, gameObject.transform.rotation);
}
While this compiles perfectly well, at runtime the prefab is not assigned and the field in the inspector returns "none".
Also, I realized the above Camera Follow script takes a class (Controller2D) as a reference, not a gameObject. Is there code that will let me automatically assign this? Thank you!
Hi there, I may be late but just in case someone has same issue. my solution comes in two parts
1- you can use a Scriptable Object to hold a reference to the prefab i e: public GameObject[] myPrefabs; then assign the values to the list on the inspector this way you'll have a persistent refrence to the prefabs so instantiate won't return a null object when spawning the absorber nor the player.
2- while you do need a reference to the prefab, you also need to set the the reference to the camera's property "`public Controller2D target`;" given that you're player spawns correctly you can attach its transform to the camera like this:
//assign back a ref to the player prefab
Player player1 = Instantiate (myScriptableobject.myPrefabs[0], gameObject.transform.position, gameObject.transform.rotation);
//find the camera or or create another property that hold the ref to the camera
Camera mycam = Instantiate (myScriptableobject.myPrefabs[1], myScriptableobject.myPrefabs[1].transform.position, myScriptableobject.myPrefabs[1].transform.rotation) ;
mycam.target = player1.target;
//assuming the target is a variable on the playerScript or a property
