Example of saving app state

Question

Does anyone have an example of this to share ?

Answer 1

This is my class for saving and retreiving top ten score in this app: http://itunes.apple.com/app/haunted-house-the-game/id396419936
import flash.net.SharedObject;
public class HighScoreShared {
var highScores: SharedObject;
var cookie_name: String;
public function HighScoreShared(cookie_name:String) {
this.cookie_name = cookie_name;
highScores = SharedObject.getLocal(this.cookie_name);
if (highScores.data.scores==undefined){
//trace("highscore undefined... create a new array");
defaultScores();
// testing
//reset();
//defaultScores();
//trace("highScores.data.scores: "+highScores.data.scores);
public function reset(){
highScores.clear();
public function defaultScores(){
highScores.data.scores = new Array();
for(var i:uint=0;i<10;i++){
highScores.data.scores.push({name:"none",value:(10-i)*100});
public function getHighScores():Array{
highScores = SharedObject.getLocal(this.cookie_name);
return highScores.data.scores;
public function getNamesFormatted():String{
var returnStr:String="";
for(var i:uint=0;i<10;i++){
returnStr+=highScores.data.scores[i].name+"\n";
return returnStr;
public function getValesFormatted():String{
var returnStr:String="";
for(var i:uint=0;i<10;i++){
returnStr+=highScores.data.scores[i].value+"\n";
return returnStr;
public function getTopOne():Number{
return highScores.data.scores[0].value;
public function getLastOne():Number{
return highScores.data.scores[9].value;
public function setNewScore(thename:String,thescore:int){
if (thename.length>10) thename = thename.substring(0,10);
highScores = SharedObject.getLocal(this.cookie_name);
if (highScores.data.scores==undefined){
//trace("error undefined!");
}else{
for(var i:uint=0;i<10;i++){
//trace("i: "+i+" value: "+highScores.data.scores[i].value);
if (highScores.data.scores[i].value <=thescore){
//trace("found the right place");
for (var j:uint=9;j>i;j--){
trace("j: "+j+" value: "+highScores.data.scores[j].value+" <--" +highScores.data.scores[j-1].value);
highScores.data.scores[j].name = highScores.data.scores[j-1].name;
highScores.data.scores[j].value= highScores.data.scores[j-1].value;
highScores.data.scores[i].name = thename;
highScores.data.scores[i].value = thescore;
//trace("i: "+i+" value: "+highScores.data.scores[i].value+" <--thescore: " +thescore);
return;
Hope this can help.
