using DataLoader to load text into a container?

Recommended Posts

Ok, I'm stumped and at this point convinced I'm coming at this from the wrong angle. Please help!

 

I'm trying to load text into a specific container, contentBox, that has scrollBar functionality in a separate scrollBar.as file. Nav buttons would load the associated data into this container. My approach was to try and specify the contentBox as a target for the DataLoader but no luck. Here's where I'm at (sorry if it's a bit messy, clean up is usually the celebratory "it works!" step) :)

 

package 
{
import flash.events.*;
import flash.display.Loader;
import flash.display.MovieClip;
import flash.filters.*;
import flash.net.URLVariables;
import flash.utils.ByteArray;
import flash.text.TextFormat;
import flash.text.TextField;
import com.greensock.events.LoaderEvent;
import com.greensock.*;
import com.greensock.plugins.*;
import com.greensock.easing.*;
import com.greensock.loading.*;

public class Screenings extends MovieClip
{
	TweenPlugin.activate([GlowFilterPlugin]);
	var subNav:SubNav = new SubNav();
	var contentBox:ContentBox = new ContentBox();
	var textLoader:DataLoader = new DataLoader("assets/copy/screenings.txt", {name:"text",x:0,y:0, onComplete:transitionIn, estimatedBytes:900});
	var buildTimeline:TimelineLite = new TimelineLite();
	var currentNav:MovieClip;
	var contentFormat:TextFormat = new TextFormat();

	public function Screenings()
	{
		subNav_mc.addEventListener(MouseEvent.MOUSE_OVER, subNavOver, false, 0, true);
		subNav_mc.addEventListener(MouseEvent.MOUSE_OUT, subNavOut, false, 0, true);
		subNav_mc.addEventListener(MouseEvent.CLICK, subNavClick, false, 0, true);
		contentBox.x = 140;
		contentBox.y = 179;
		contentBox.alpha = 0;
		buildTimeline.append(new TweenLite(horizBar_mc, .8, {x:0, ease:Sine.easeIn}));
		buildTimeline.append(new TweenLite(contentBox, .4, {alpha:1,ease:Sine.easeOut}));
		buildTimeline.append(new TweenLite(subNav_mc, .4, {alpha:1,ease:Sine.easeOut}));
		addChildAt(contentBox,2);
		subNav_mc.alpha = 0;
		TweenMax.to(subNav_mc.screenings, 0, {glowFilter:{color:0xffffff, alpha:1, strength:1.5, blurX:8, blurY:8, quality:2,ease:Sine.easeOut}});
		contentBox.drag.visible = false;
		contentBox.scrollBar.visible = false;
		textLoader.load();
		contentFormat.size = 14;
		contentBoxTitle.defaultTextFormat = contentFormat;
	}
	public function transitionIn(event:LoaderEvent):void
	{
		TweenLite.to(contentBox, 1, {alpha:1});
	}
	function subNavOver(e:MouseEvent):void
	{
		subNav_mc.buttonMode = true;
		subNav_mc.screenings.mouseChildren = false;
		subNav_mc.news.mouseChildren = false;
		subNav_mc.pressReleases.mouseChildren = false;
		var navItem:MovieClip = e.target as MovieClip;
		if (navItem != currentNav)
		{
			TweenMax.to(navItem, .3, {glowFilter:{color:0xffffff, alpha:1, strength:1.5, blurX:8, blurY:8, quality:2,ease:Sine.easeOut}});
		}
	}
	function subNavOut(e:MouseEvent):void
	{
		var navItem:MovieClip = e.target as MovieClip;
		if (navItem != currentNav)
		{
			TweenMax.to(navItem, .3, {glowFilter:{alpha:0}});
		}
	}
	function subNavClick(e:MouseEvent):void
	{
		contentBoxTitle.text = e.target.name.toUpperCase();
		TweenMax.to(subNav_mc.screenings, .3, {glowFilter:{alpha:0}});
		var navItem:MovieClip = e.target as MovieClip;
		if (currentNav != null)
		{
			TweenMax.to(currentNav, .3, {glowFilter:{alpha:0}});
		}
		TweenMax.to(navItem, 0, {glowFilter:{color:0xffffff, alpha:1,strength:1.5, blurX:8, blurY:8, quality:2,ease:Sine.easeOut}});
		currentNav = navItem;
		function loadNext(swfUrl:String):void
		{
			textLoader.dispose(true);
			textLoader= new DataLoader(swfUrl, {name:"text",x:0,y:0, onComplete:transitionIn, requireWithRoot:this.root, estimatedBytes:900});
			textLoader.load();
		}
		if (currentNav == navItem)
		{
			TweenLite.to(contentBox, 1, {alpha:0, ease:Sine.easeOut, onComplete:loadNext, onCompleteParams:["assets/copy/" + e.target.name + ".txt"]});
		}
	}
}
}

 

Thanks for your help!

I don't see anywhere that you take the text and put it anywhere. So the DataLoader loads the text but you don't do anything with it. I assume you meant to do that in the method that you're calling when the DataLoader completes (transitionIn()) like:

 

public function transitionIn(event:LoaderEvent):void {
contentBox.text = textLoader.content;
TweenLite.to(contentBox, 1, {alpha:1});
}

 

Right?

ah man, yup, that was it as well as I was ignoring the children of the contentBox. ContentBox is a movieclip, within that is another movieclip called container_mc (used for scrolling a mask, and within that is the text box. So I wasn't loading AND I wasn't targeting the right object. genius...

 

thank you!
