HI guys,

I have a problem with this TextSlider class.
I got an error saying that the slider is null and I can’t find the problem.

Here is the class file or if you are lazy to go to the site and download, I have also attach the class file with this post.
While my code is (which I copied from their example);


import com.flashandmath.dg.text.TextSlicer;
import fl.transitions.TweenEvent;
import fl.transitions.Tween;
import fl.transitions.easing.*;

var ldr:URLLoader = new URLLoader();
var slicer:TextSlicer
var paramObj:Object;
var paramTween:Tween;
var textBoard:Sprite;
var fileContent:String;
var isMoving:Boolean=false;
var curCont:int=0;

txtOutput.wordWrap=true;
txtOutput.mouseEnabled=false;
ldr.addEventListener(Event.COMPLETE, loadComplete);
ldr.addEventListener(IOErrorEvent.IO_ERROR, loadError);
ldr.load(new URLRequest("home.txt"));

function loadComplete(e:Event):void {
    fileContent = ldr.data; 
    txtOutput.text="Click anywhere on the Stage to display or repeat text animation.";
    ldr.removeEventListener(Event.COMPLETE, loadComplete);
    ldr.removeEventListener(IOErrorEvent.IO_ERROR, loadError);
    init();
}

function loadError(e:IOErrorEvent):void {   
    txtOutput.text = "Error loading an external file. The server may be busy. Try refreshing the page.";
}

function init():void {
    textBoard = new Sprite();
    textBoard.x = 40;
    textBoard.y = 60;
    this.addChild(textBoard);
    slicer = new TextSlicer;
    slicer.fontSize = 24;
    slicer.fontColor = 0x000000;
    slicer.numLinesPerSlice = 1;
    slicer.vertPadding=2;
    slicer.importText(fileContent, "textLayout");
    for (var i:int = 0; i < slicer.numContainers; i++) {   
        textBoard.addChild(slicer.containers*);
        slicer.containers*.x = 0;
        slicer.containers*.y = i*slicer.slatHeight;
        slicer.containers*.alpha = 0;
    }
    
    stage.addEventListener(MouseEvent.CLICK, onClick);
    paramObj = {t:0};
}

function onClick(evt:MouseEvent):void {
    if(isMoving){return;}
    isMoving=true;
    curCont=0;
    for (var i:int = 0; i < slicer.numContainers; i++) {
        slicer.containers*.alpha = 0;
    }
    
    paramTween = new Tween(paramObj, "t", Regular.easeOut, 0, 1, 24);
    paramTween.addEventListener(TweenEvent.MOTION_CHANGE, onMotionChange);
    paramTween.addEventListener(TweenEvent.MOTION_FINISH, onMotionFinish);
}

function onMotionChange(evt:TweenEvent):void {
    if(curCont < slicer.numContainers){
        slicer.containers[curCont].alpha = paramObj.t*paramObj.t*paramObj.t*paramObj.t;
    }
}

function onMotionFinish(evt:TweenEvent):void {
    paramTween.removeEventListener(TweenEvent.MOTION_CHANGE, onMotionChange);
    paramTween.removeEventListener(TweenEvent.MOTION_FINISH, onMotionFinish);
    curCont+=1;
    if(curCont==slicer.numContainers){
    isMoving=false;
    } else {
    paramTween = new Tween(paramObj, "t", Regular.easeOut, 0, 1, 24);
    paramTween.addEventListener(TweenEvent.MOTION_CHANGE, onMotionChange);
    
    paramTween.addEventListener(TweenEvent.MOTION_FINISH, onMotionFinish);
    }
}

I am not really good in reading classes. Can anyone point out where I d wrong?

I have a dynamic textfield with instance name ‘txtOutput’.

Thanks in advanced.
