AutoType script problem.

[yusolaifdfer]

I am trying to make a small cutscene with some text shown in the bottom of screen I want the text to appear one word at a time like in RPG games.
I tried using the AutoType script, it works fine when I put it on the guitext and put the text in the guitext using inspector.
But when I use a script like

var textString : GUIText;
function Start {
textString.guiText.text = "Testing";
} 

it doesn’t work like its supposed to work with the AutoType script.
For who don’t know about AutoType here is the link and code itself.

var letterPause = 0.2;
var sound : AudioClip;
 
private var word;
 
function Start () {
	word = guiText.text;
	guiText.text = "";
	TypeText ();
}
 
function TypeText () {
	for (var letter in word.ToCharArray()) {
		guiText.text += letter;
		if (sound)
			audio.PlayOneShot (sound);
		yield WaitForSeconds (letterPause);
	}		
}

This is because in the Start() method the script actually runs some logic and it launches the TypeText() coroutine. However when you change the text property manually, you do not trigger the effect, TypeText() isn’t called. This is what I advise:

var letterPause = 0.2;
var sound : AudioClip;

private var message;

function Start () {
    SetText(guiText.text);
}

function TypeText () {
    for (var letter in message.ToCharArray()) {
       guiText.text += letter;
       if (sound)
         audio.PlayOneShot (sound);
       yield WaitForSeconds (letterPause);
    }   
}

function SetText(text : string)
{
    StopCoroutine("TypeText");
    message = text;
    guiText.text = "";
    StartCoroutine("TypeText");
}

And from now on, use SetText("message"); to change the text, and it will even stop the current AutoTyping and start it over with the new text.
