Can anyone help me how to access a data from an fla file to another fla file? - actionscript-3

Question

Can anyone help me how to access a data from an fla file to another fla file?
I have a starting fla file called "savescore.fla" which is connected to the class called "score.as".I have a "btnAdd" button that if clicked, it will add by one to the variable "scoring" in the class "score.as". I have also a movieclip "btnSave" that would save the score. Lastly, I have a "next_btn" button that would go directly to my another fla file
which is "finalscore.fla". I wanted the "finalscore.fla" to show the current "scoring" variable from the "score.as" class but the problem is that it will only show 0/zero as the score. I think that as "savescore.fla" saves and edits the variable in the "score.as", it will only make changes to itself and not to the "score.as" that's why I still got 0 as the final score because it comes from the "score.as" and not from "savescore.fla". So I was thinking if I could just access the score from the "savescore.fla", it would solve the problem. But I have no idea what codes to put...or can you give me another way?
Here are the codes: (Btw, I am using actionscript 3.0)
savescore.fla:
var lol:score = new score();
var saveDataObject:SharedObject;
//var currentScore:int;
init(); // this line goes directly beneath the variables
function init():void{ // call once to set everything up
saveDataObject = SharedObject.getLocal("test"); // give the save data a location
btnAdd.addEventListener(MouseEvent.CLICK, addScore); // clicking on +1
btnSave.addEventListener(MouseEvent.CLICK, saveData); // clicking on Save
next_btn.addEventListener(MouseEvent.CLICK, sunod); // clicking on +1
if(saveDataObject.data.savedScore == null){ // checks if there is save data
trace("No saved data yet."); // if there isn't any data on the computer...
saveDataObject.data.savedScore = lol.scoring; // ...set the savedScore to 0
} else {
trace("Save data found."); // if we did find data...
loadData(); // ...load the data
}
}
function addScore(e:MouseEvent):void{
lol.scoring+=1; // add 1 to the score
}
function saveData(e:MouseEvent):void{
saveDataObject.data.savedScore = lol.scoring; // set the saved score to the current score
trace("Data Saved!");
saveDataObject.flush(); // immediately save to the local drive
trace(saveDataObject.size); // this will show the size of the save file, in bytes
trace(lol.GetFullScore());
}
function loadData():void{
lol.scoring = saveDataObject.data.savedScore; // set the current score to the saved score
trace("Data Loaded!");
}
function sunod(event:MouseEvent):void{
var ldr:Loader=new Loader();
ldr.load(new URLRequest("finalscore.swf"));
addChild(ldr);
}
score.as:
package{
public class score{
public var scoring:int;
function score()
{
}
public function SetScore(val:int):void
{
scoring = val;
}
public function GetFullScore():int
{
return scoring;
trace(scoring);
}
}
}
finalscore.fla:
var lol1:score = new score();
txtScore.text = ("Score: " + lol1.GetFullScore()); // set the text property of the txtScore
trace(lol1.GetFullScore());

Once you have loaded an external swf you can grab a reference to it in an onLoadedHandler. So in savescore:
var myReference:Object;
function loadComplete(event:Event):void {
myReference= event.target.content;
myReference.lol1.GetFullScore();
... or...
var myScore = event.target.lol1.GetFullScore();
etc...
}
you'll want to make sure the reference exists before you use it
EDIT
in your Child SWF create a variable and method to store the parent:
var parentSWF:MovieClip;
function setParent(myParent:MovieClip):void{
parentSWF = myParent;
}
then in the parent send the child a reference :
function loadComplete(event:Event):void {
myReference= event.target.content;
// use the reference to child to call
// any variables or functions in it
myReference.lol1.GetFullScore();
// set the reference in child with the following
// so that the child can call the parent
myReference.setParent(this);
}
then in child you can use lol :
parentSWF.lol;
If you had to go this way you would ideally create measures to check the objects/methods etc exist before they are used
FINAL EDIT
For a start, move
var ldr:Loader=new Loader();
out of the sunod function and put it at the top with the other declaration so that loadcomplete can use it. You need to set up a listener for the loadComplete handler. Put this after your other listeners
ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
in your loadcomplete handler in savescore add
myReference.doThisWhenLoaded();
in finalscore put
function doThisWhenLoaded():void{
txtScore.text = ("Score: " + parentSWF.lol);
}
This just seems complete overkill and I'm sure I've overcomplicated your over complications(!). My advice would be to do away with the second swf and just create a finalscore.as object in savescore. This would be so much easier. At the moment I can't see why you want to have another swf floating around. I've never been a fan of multiple swfs though so someone else may well jump in and correct this.

Here's the changes of my code:
savescore.fla:
var lol:score = new score();
var saveDataObject:SharedObject;
init(); // this line goes directly beneath the variables
function init():void{ // call once to set everything up
saveDataObject = SharedObject.getLocal("test"); // give the save data a location
btnAdd.addEventListener(MouseEvent.CLICK, addScore); // clicking on +1
btnSave.addEventListener(MouseEvent.CLICK, saveData); // clicking on Save
next_btn.addEventListener(MouseEvent.CLICK, sunod); // clicking on +1
if(saveDataObject.data.savedScore == null){ // checks if there is save data
trace("No saved data yet."); // if there isn't any data on the computer...
saveDataObject.data.savedScore = lol.scoring; // ...set the savedScore to 0
} else {
trace("Save data found."); // if we did find data...
loadData(); // ...load the data
}
}
function addScore(e:MouseEvent):void{
lol.scoring+=1; // add 1 to the score
}
function saveData(e:MouseEvent):void{
saveDataObject.data.savedScore = lol.scoring; // set the saved score to the current score
trace("Data Saved!");
saveDataObject.flush(); // immediately save to the local drive
trace(saveDataObject.size); // this will show the size of the save file, in bytes
trace(lol.GetFullScore());
}
function loadData():void{
lol.scoring = saveDataObject.data.savedScore; // set the current score to the saved score
trace("Data Loaded!");
}
function sunod(event:MouseEvent):void{
var ldr:Loader=new Loader();
ldr.load(new URLRequest("finalscore.swf"));
addChild(ldr);
}
var myReference:Object;
function loadComplete(event:Event):void {
myReference= event.target.content;
myReference.lol1.GetFullScore();
myReference.setParent(this);
}
finalscore.fla:
var lol1:score = new score();
var parentSWF:MovieClip;
txtScore.text = ("Score: " + parentSWF.lol); // this line has the error because of parentSWF.lol
trace(lol1.GetFullScore());
function setParent(myParent:MovieClip):void{
parentSWF = myParent;
}
score.as:
package{
public class score{
public var scoring:int;
function score()
{
}
public function SetScore(val:int):void
{
scoring = val;
}
public function GetFullScore():int
{
return scoring;
trace(scoring);
}
}
}
