Anyone know how to fix this error?

Do you have code that lead to this?
We could do a lot of blind guessing that wouldn’t get you anywhere I fear.

It happens as soon as you exit the menu into the game scene. I can post the whole game script but it’s pretty long

had to chop out some bits to fit it in but I don’t know which bit in it is causing the error. It happens the moment the scene is loaded and there’s no other scripts in the scene.

From the error it sounds like GetRenderer is the problem but I don’t know where in my code that appears

EDIT:

so changing all the gameObject.renderer

into

var temp : Renderer = gameObject.GetComponent(Renderer)

Causes the same error but with “renderer” replaced by “GetComponent” in the error message

Could it be because I’m using Array()?
Lets give that a try…

EDIT2:

YEA!
Thanks unity community, solved it. It was indeed the use of javascript arrays and the lack of dynamic type setting in iphone. It didn’t get flagged up in the editor so I missed it.

Assigning the contents of the Array to a game object variable let me perform the required tasks on the objects in the array without the game crashing

@spinaljack -

I have the same problem. Can you post what piece of code you changed?
