Scripting errors only when building for iPhone
I have encountered a problem when building for iPhone. It is strange because it only complains for when building for iphone, but then complains at the corrected code when I try it in the editor.
i get an error on these kind of lines.
var obj : GameObject = Instantiate( coinPrefab ).gameObject;
this returns: BCE0019: 'gameObject' is not a member of 'UnityEngine.Object'.
To get this code to build, I simply removed the ".gameObject", and then it compiles fine ( but only when building for iPhone, not for testing in editor )
So my question is: Is there something wrong with this code? Or is there a discrepancy in Unity?
I don't get why you'd do this... If you want to instantiate an object, wouldn't you just put the Instantiate code in? Is this what you're trying to do? $$anonymous$$aybe I'm reading this all wrong, but doesn't make sense to meeee, sorry.
thats what gives me an error when building for iPhone, if i only use Instantiate(coinPrefab), then i get an error in the editor
Instantiate returns an Object, which does not have a gameObject property.
You would need to do something like this:
var obj : GameObject = Instantiate( coinPrefab ) as GameObject;
Hope that helps.

I'll try this out, but code from the scripting reference suggest that it should work even though it is an Object

in the second box :)
Well, yeah in some cases this would work due to the implicit typecasting allowed in Unity's JS. For example, it would work if you were instantiating a Component or some type of $$anonymous$$onobehaviour, because they have a .gameObject property, but since you are using Instantiate to instantiate a GameObject (your Prefab), if you check the docs the GameObject class has no .gameObject because it is a GameObject. $$anonymous$$ake sense?
Instantiate returns type Object which does not have a .gameObject
var obj : GameObject = (GameObject) (Instantiate( coinPrefab ));
or
var obj : GameObject = Instantiate( foo ) as GameObject;
or
var obj : GameObject = Instantiate( foo );
...are all correct ways
In my case noone of the above worked to solve the issue (both for the editor and for iphone). I did solve it however by using a Transform var as an intermediate:
var tobj : Transform = Instantiate( coinPrefab );//.gameObject; var obj : GameObject = tobj.gameObject;
it's impossible for us to know what type coinPrefab is. It could be a rigidbody for all we know. Only you and your code knows. The above answer is how to correctly cast in javascript! I am glad you have fixed your script!
