programming problem

Code (JavaScript):

1. #pragma strict
2.  
3. var ScoreUI : UI.Text;
4. var ScoreInt : int = 0;
5. var Score2Int : int = 0;
6.  
7. var Ball : GameObject;
8. var BallTransform : Transform;
9. var BallSpawn : Transform;
10.  
11. function Start () {
12.     BallTransform = GameObject.FindGameObjectsWithTag("Ball");
13. }
14.  
15. function Update () {
16.     ScoreUI.text = ("Home "+ ScoreInt+" - "+Score2Int+" Away");
17. }
18.  
19. function OnTriggerEnter (other : Collider) {
20.     if (other.tag == "Ball")
21.     {
22.         ScoreInt += 1;
23.         BallTransform.transform.position = BallSpawn.position;
24.         ScoreUI.text = ("Home "+ ScoreInt+" - "+Score2Int+" Away");
25.     }
26. }

I get the error "Cannot convert 'unityengine.GameObject[]'to 'unityengine.Transform",
can someone give me the exact code that works?

 

Code (JavaScript):

1. BallTransform = GameObject.FindGameObjectsWithTag("Ball");

FindGameObjectsWithTag returns a GameObject, however your variable is of type Transform. Also note that your are using FindGameObjectsWithTag which returns multiple instances in an array if found. So your code should look like this:

Code (JavaScript):

1. BallTransform = GameObject.FindGameObjectsWithTag("Ball")[0].transform;

Note that this is still not error prone as you should probably check if any objects were found at all.

 

Code (CSharp):

1. function Start () {
2.     BallTransform = GameObject.FindGameObjectsWithTag("Ball").transform;
3. }
