Alright here is what i am trying to do. I have a health script so that when i get shot it displays a hint (much like the one in 'Red Dead Redemption') saying get to cover. The hint is a GUIText object, which is rendered over a GUITexture background. I want it so that when i want to display the hint, the texture fades in and out instead of just popping in and out as it looks odd, and unfinished. So my solution was to make a script which is NOT attached to the GUITexture (for varies reasons) and i want to have it separate from my hint script as i will have more hints (meaning more scripts) then JUST getting shot, and i want it universal. So my idea was this:

static function FadeOut () {
    var HintsBackground = GameObject.Find("HintBackground");
    while (HintsBackground.color.a > .1) {
        HintsBackground.color.a -= Time.deltaTime;
    }
}

The problem is since the function has to be static if i want to call it, i cant simply use: var HintsBackground : GUITexture. So my solution was GameObject.Find...problem is 'color' is NOT a member of GameObject. So what i am asking is, how can i either, change GameObject to GUITexture, or what is the best way to call a GUITexture. Thank you for you time.
