trying to implement my own Timer class - having problems

hey guys,

I'm trying to implement my own Timer-Display Class in JScript.
(Unfortunately without success)

The Timer-Code itself I've got from this page:
http://www.der-softwareentwickler-blog.de/2010/08/02/unity-3d-tutorial-22-countdown-mit-yield-waitforseconds/
(and from another page, but can't find the link right now..)

The Problems I've encountered:
Well, my Console-Debug-Output never happens.
(I'm using yield for the first time btw. I'm sure I'm doing something wrong with this,
but I've allready tried so many different things. ^^)

Here's the code I've got so far:

PHP:


class TimerDisplay {
    
    private var seconds : int;
    private var timeStart;
    private var time;
    private var restSeconds : int;
    private var roundedRestSeconds : int;
    private var displaySeconds : int;
    private var displayMinutes : int;
    //private var guiCountDown : GUIText;
    
    function Initiate( seconds ) {
        this.seconds = seconds;
    }
    
    function myFunc() {
        Debug.Log( "test1" );
        var myVar = doIt();
    }
    
    function doIt() : IEnumerator {
        
        Debug.Log( "test2" );
        this.timeStart = Time.time;
        
        for( var i = this.seconds; i > 0; i-- ) {
            
            this.time               = Time.time - timeStart;
            this.restSeconds        = this.seconds - ( this.time );
            this.roundedRestSeconds = Mathf.CeilToInt(restSeconds);
            this.displaySeconds     = roundedRestSeconds % 60;
            this.displayMinutes     = roundedRestSeconds / 60; 
            
            text = String.Format ( "{0:00}:{1:00}", displayMinutes, displaySeconds ); 
            //this.object.GUI.Label( Rect ( 400, 25, 100, 30 ), text );
            Debug.Log( displayMinutes + " " + displaySeconds );
            
            yield WaitForSeconds (1);
        }
    }
}



The Method-Function MyFunc() was just one of my many tests.
(I read that yield does a return when called, that's why i tried that..)

What am I doing wrong?
Please help!
Thanks

 

hey,

I made some progress.
My Class works, if it inherits from MonoBehaviour!
(I'm guessing YIELD only works when inheriting from Unity's GameObject or MonoBehaviour Class)

There is still one little question I have!

First, here's the code I'm using at the moment:

TimerDisplay.js

PHP:


class TimerDisplay extends MonoBehaviour {
    
    private var seconds : int;
    private var timeStart;
    private var time;
    private var restSeconds : int;
    private var roundedRestSeconds : int;
    private var displaySeconds : int;
    private var displayMinutes : int;
    
    function Init( seconds ) {
        this.seconds = seconds;
    }
    
    function doIt() {
        
        this.timeStart = Time.time;
        for( var i = this.seconds; i > 0; i-- ) {
            
            this.time               = Time.time - timeStart;
            this.restSeconds        = this.seconds - ( this.time );
            this.roundedRestSeconds = Mathf.CeilToInt(restSeconds);
            this.displaySeconds     = roundedRestSeconds % 60;
            this.displayMinutes     = roundedRestSeconds / 60; 
            
            Debug.Log( displayMinutes + " " + displaySeconds );
            text = String.Format ( "{0:00}:{1:00}", displayMinutes, displaySeconds ); 
            //GUI.Label( Rect ( 400, 25, 100, 30 ), text );
            
            yield WaitForSeconds (1);
        }
    }
}



onStart.js

PHP:


function Start () {
    Debug.Log( "Start" );
    var timerDisplay = gameObject.AddComponent("TimerDisplay");
    timerDisplay.Init( 5 );
    timerDisplay.doIt();
    Debug.Log( "End" );
}



As you can see above, the Script is added in runtime with AddComponent.
(the script-class is not attached to a gameobject)

Unfortunately I can't access GUI.Label this way.
I allways get the error message:
"object reference is not set to an instance of an object"

My Question:

Is there any other way to make this work?
To call GUI.Label from my Class without having to attach the Script to a GameObject?
I thougt by calling AddComponent I would automatically attach the Script to the GameObject??
