Add text such as the following to a text file:

var1=a|var2=b|var3=c|var3=d

Add the following ActionScript to a new Flash document saved in the same directory as the text file. In this example it’s assumed that the text file is called myData.txt.

var variables:Object = new Object(); var myVars:LoadVars = new LoadVars();

myVars.onData = function(str:String):Void { var data:Array = str.split(“|”);

var item:Array;

for(var i:Number = 0; i < data.length; i++) { item = data[i].split(“=”); variables[item[0]] = items[1];

You don’t add the URL as a node, but as an attribute because a URL is unlikely to have child considerations.

Exercise 3 Solution

stations = new XML(); stations.ignoreWhite = true; stations.onLoad = function(success) {

var out = []; if (success) {

var main = this.firstChild;

for (var i in main.childNodes) { var node = main.childNodes[i]; var outRecord = out[i]={};

outRecord.id = node.attributes.identification; outRecord.url = node.attributes.url;

for (var j in node.childNodes) {

var nodeNameStr = node.childNodes[j].nodeName.toLowerCase(); if (nodeNameStr == “name”) {

outRecord.name = node.childNodes[j].firstChild.toString();

}

if (nodeNameStr == “desc”) {

outRecord.desc = node.childNodes[j].firstChild.toString();

}

}

}

stations = out;

stations.load(“stations.xml”);

Create one SWF file called controls.swf containing two button components labeled “Play” and “Pause” and with instance ids playButton and pauseButton. You can use animation.swf from the last Chapter 10 Try It Out exercise as a placeholder.

var commandLocalConnection = new LocalConnection();

var buttonListener:Object = new Object(); buttonListener.click = function(eventHandle:Object)

{

switch (eventHandle.target._name)

{

case “playButton”:

commandLocalConnection.send(“commandChannel”, “controlPlayback”,

“play”);

break;

case “pauseButton”:

commandLocalConnection.send(“commandChannel”, “controlPlayback”, ; “pause”);

break;

}

}

playButton.addEventListener(“click”, buttonListener); pauseButton.addEventListener(“click”, buttonListener);

animationHolder.swf

this.createEmptyMovieClip(“animationHolder”, this.getNextHigherDepth()); animationHolder.loadMovie(“animation.swf”);

var commandLocalConnection:LocalConnection = new LocalConnection(); commandLocalConnection.controlPlayback = function(commandString:String)

{

switch(commandString)
