Hello, I have a similar problem to this post, but not quite: http://answers.unity3d.com/questions/28878/show-gui-text-when-distance-6

I have a bunch of paintings and I want a window to appear with information about each painting as the user gets near it. I'd like this to fade in and out as they approach and leave the proximity of each painting.

I have the proximity issue solved with a OnTriggerEvent(other: Collider) and I use a collision sphere for each painting (maybe there's a better way? Tried RayCasting but it didn't work).

Here are the questions:

1. I'm using GUI.Box(Rect(10, 50, 300, 200), "Details:"); to draw the background. Should I be using a GUITexture instead? If so, how to manage it?
2. I need to have different text for each painting, how can I accomplish this? If I create GUIText objects, they're always there and I don't know how to hide them then call them up again.
3. Is there a way to tell Unity to read the text from a file?
4. Lastly, how can I make the whole thing (background and text) fade in and out when called?

I know these are a lot of questions in one, but mostly I'm looking for guidance on how to accomplish this properly, I've been looking at the documentation and examples and have not been able to figure things out successfully, very new to Unity.

Thanks in advance.

I've enhanced the code so that now I can get the GUITexture to hide and then display when I am near an object. However, the Fade function is not working properly. It will not display at all if I have this code (copied from the Wiki): Fade.use.Alpha(myGuiTexture, 0.0, 1.0, 2.0, http://EaseType.In); or any other use of Fade, even in the "else" statement below. Any ideas are welcome.

Full code here:

private var myWindow: boolean;
private var windowOn : boolean;
private var windowRect : Rect = Rect (150, 150, 120, 50);//window parameters

var cuadroText : GUIText;
var myGuiTexture : GUITexture;

myGuiTexture.enabled = false;

function OnTriggerEnter (other : Collider) {
    myWindow = true;
}

function OnTriggerExit (other : Collider) {
    myWindow = false; // hide window
}


function OnGUI () {

    if (myWindow == true) {

    // fade in del gui background
    myGuiTexture.enabled = true; // first we activate the guiTexture
    Fade.use.Alpha(myGuiTexture, 0.0, 1.0, 2.0, EaseType.In);
    GUI.Box(Rect(10, 50, 300, 200), "Details:"); // draw a box to make sure things are working.


    }  else {
            // fade out
        //Fade.use.Alpha(myGuiTexture, 1.0, 0.0, 3.0);
        myGuiTexture.enabled = false; // disable it.
        windowOn = false;
        }

}
