Array of game objects?

If I have an array full of game objects, how can I set them all false (at the same time)?

As Jesse said, not quite sure what you mean by setting them to false. You mean inactive?

You can use this kind of structure to act on all members of an array:

var myArray : GameObject[];

    function Update ()
    {
    for (var myObjects in myArray)
    {
    // do this
    }
    }
