Instantiate prefab (button, texture) with attached script

Question

Hey guys,

So here's my issue, I want to instantiate multiple prefabs with different components in the attached script and set the prefab child button Onclick to a function located in the script.

 GameObject prefab;
 public GameObject parentGameObject;

 void LoadPrefab() {

 prefab = (GameObject)Instantiate(Resources.Load("MyPrefab"));
 prefab.transform.SetParent(parentGameObject.transform);
 prefab.transform.localScale = new Vector3(1,1,1);
 prefab.AddComponent<MyScript>();
 prefab.AddComponent<MyScript>();
 prefab.GetComponent<MyScript>().DataInt = Data;
 prefab.GetComponent<MyScript>().DataVector = DataVector.point;
 prefab.transform.Find ("btn_goTo").GetComponent<Button> ().onClick.AddListener (delegate {prefab.GetComponent<MyScript>().FunctionInMyScript();}); }

The aim is : when the user click on the button, my camera is moving to the DataVector position. Now each prefab seems to have the same script attached... How can I fixed this ? Thanks in advance ! :)

It seems you are adding your "MyScript" twice.

Are you sure the data you set to your script are different at least ? Add Debug.Log when changing the value !

By the way, it would be clearer and more efficient to write something like this :

 private GameObject newObject;
 public GameObject parentGameObject;

 void LoadPrefab()
 {
     MyScript myScript ;
     newObject = (GameObject)Instantiate(Resources.Load("MyPrefab"));
     myScript = newObject.AddComponent<MyScript>();
 
     newObject.transform.SetParent(parentGameObject.transform);
     newObject.transform.localScale = new Vector3(1,1,1);
 
     myScript.DataInt = Data;
     myScript.DataVector = DataVector.point;
     newObject.transform.Find ("btn_goTo").GetComponent<Button> ().onClick.AddListener ( delegate {myScript.FunctionInMyScript();} );
 }
