Even if you’re bad at coding, it’s a good idea to read the manuals first.

First answer: Yes. Definitely possible. Dave’s suggestion of using a trigger is definitely a good idea, though you could also set a distance. Here’s a snip of code from a label that fades in and out based on the distance you are from it, and rotates to face the camera. Read through it a bit and then rework it for what you need if you’d like:

//Set the distance at which the object fades, and how far it takes.
var FadeStart : int = 150;
var FadeDist : int = 5;

//Which items should fade?
var Panel : GameObject;
var TextBox : GameObject;

private var FadeEnd : int;


function Update () {


//Check the distance between the active camera and the text
var dist = Vector3.Distance(Camera.main.transform.position, transform.position);
FadeEnd = FadeStart+FadeDist;


//Rotate the text to face the camera, as long as you're more than 5m away
	if(Panel.renderer.isVisible){
		if(dist>5){
			transform.LookAt(Camera.main.transform);
			transform.eulerAngles.x = 0;
			}
			
	//Fade the text and box, with an alpha between 0 and .75			
		if(dist>FadeStart && dist<FadeEnd){
			var renderAlpha = 1-(dist-FadeStart+(.4*FadeDist))/FadeDist;
			Panel.renderer.material.color.a = renderAlpha;
			TextBox.renderer.material.color.a = renderAlpha;
			Debug.Log(renderAlpha);
			}
		if(dist>=FadeEnd){
			Panel.renderer.material.color.a = 0;
			TextBox.renderer.material.color.a = 0;
			}
		if(dist<=FadeStart){
			Panel.renderer.material.color.a = 0.75;
			TextBox.renderer.material.color.a = 0.75;
			}			
	}
}
