Question by The-BOOM · Feb 07, 2012 at 06:21 AM · instantiatecasting

Instantiate Casting

Here's my code:

 var firstBall : GameObject;
 var secondBall : GameObject;
 var ballPrefab : GameObject;
 
 function Clicked ()
 {
         ...
 
     firstBall = Instantiate(ballPrefab, firstSpawnSpot, transform.rotation);
     secondBall = Instantiate(ballPrefab, secondSpawnSpot, transform.rotation);
 
         ...
 
 }

... is other code that doesn't matter. The error I keep getting is InvalidCastException, but I don't get where the casting error comes from.

Have you tried adding 'as GameObject' at the end of those lines?

That didn't work, but me messing around with the code, saving it, then putting it back to this, saving it again, then detatching it, then reattatching it got it to work fine.

There must've been a bad connection or something.

firstBall = (GameObject)Instantiate(ballPrefab, firstSpawnSpot, transform.rotation); secondBall = (GameObject)Instantiate(ballPrefab, secondSpawnSpot, transform.rotation);

I will rewrite this in c#. Hopefully you can get the gist of it and change it to JavaScript. Sorry but I'm not familiar with Unity3Ds JavaScript.

 public GameObject firstBall;
 public GameObject secondball;
 public GameObject ballPrefab;
 //you need to have GameObject variables for the spawn spots as well
 public GameObject firstSpawnSpot;
 public GameObject secondSpawnSpot;
 
 void Clicked(){
      firstBall = Instantiate(ballPrefab, firstSpawnSpot.transform.position, firstSpawnSpot.transform.rotation;
 
      secondBall = Instantiate(ballPrefab, secondSpawnSpot.transform.position, secondSpawnSpot.transform.rotation;
 
 }
