Actionscript 3 saving currentframe location to local hard drive? - actionscript-3

I asked similar question sometime ago, but I am making new one to be much more specific with my question with some example!
I´ve found this code snippet/tutorial from googling, but I cant seem to figure out how to modify it for my needs:
// open a local shared object called "myStuff", if there is no such object - create a new one
var savedstuff:SharedObject = SharedObject.getLocal("myStuff");
// manage buttons
btnSave.addEventListener(MouseEvent.CLICK, SaveData);
btnLoad.addEventListener(MouseEvent.CLICK, LoadData);
function SaveData(MouseEvent){
savedstuff.data.username = nameField.text // changes var username in sharedobject
savedstuff.flush(); // saves data on hard drive
}
function LoadData(MouseEvent){
if(savedstuff.size>0){ // checks if there is something saved
nameField.text = savedstuff.data.username} // change field text to username variable
}
// if something was saved before, show it on start
if(savedstuff.size>0){
nameField.text = savedstuff.data.username}
So what I am trying to figure out how to do, is to save users current frame to local hard drive, as my flash progress is based on frame location. yeah, so how do I modify it so that it stores data of current frame? and how about current frame inside movieclip, if that is makes things different?
help MUUUCH appreciated! thanks!

In your example it looks like it is already saving something to the shared object:
savedstuff.data.username = nameField.text;
Just replace it with the movie clip frame value instead (and probably under a different property name other then "username").
Then on load, there is another line where it loads the data:
nameField.text = savedstuff.data.username;
It would be the same way, except replace "username" with whatever property name you choose. Then you may have to parse into an int again and use it to restore progress however way you have it set up.

How do I keep a variable consistant even after seperate play sessions?

I have a variable area which stores a number.
When the app is restarted, it is reset back to it's original value. How can I keep area persistent after being closed?
I'm using Flash CS6 for Android
You'll have to save the variable. There's multiple ways to do this but using a SharedObject is the easiest IMO.
First thing is you don't actually create a new instance of the SharedObject class, you instead call the static function getLocal and this sets your variable. So somewhere near the start of your program you'll want something like this:
var gameSave:SharedObject = SharedObject.getLocal("gameSave");
This either creates a new locally persistent shared object if one does not exist or it grabs the one with the same initialized name ("gameSave") on your computer. This way you can access the saved variables across multiple playthroughs.
Now to save a variable you simply use the dataObject on the shared object and write values to it, then you call the function flush when you're done writing values to immediately save the shared object to your computer.
So saving your area value would look something like this:
gameSave.data.area = Main.area;
gameSave.flush();
After that you'll want to set the area value to whatever the saved value is when your game launches:
if (gameSave.data.area !== undefined) Main.area = gameSave.data.area;
We check if the value is undefined because it might not exist yet if you're playing the game for the first time and the area hasn't been saved yet.
Last thing in case you want to expand the scope of this and save more values: you can only write specific values to the shared object. The way I understand it is you can only write certain class types and primitives. If you try to write anything that's not a primitive or the exception classes, it'll automatically convert that item to an Object and it more or less becomes useless. The classes that it can accept that you'll probably use the most are: int, uint, Number, String, Boolean, Object, and Array. It has a few others like ByteArray and XML, but you'll either not use those at all or not use them very frequently. If you want to save any other class type you'll have to add that functionality yourself.

Append string to a Flash AS3 shared object: For science

So I have a little flash app I made for an experiment where users interact with the app in a lab, and the lab logs the interactions.
The app currently traces a timestamp and a string when the user interacts, it's a useful little data log in the console:
trace(Object(root).my_date + ": User selected the cupcake.");
But I need to move away from using traces that show up in the debug console, because it won't work outside of the developer environment of Flash CS6.
I want to make a log, instead, in a SO ("Shared Object", the little locally saved Flash cookies.) Ya' know, one of these deals:
submit.addEventListener("mouseDown", sendData)
function sendData(evt:Event){
{
so = SharedObject.getLocal("experimentalflashcookieWOWCOOL")
so.data.Title = Title.text
so.data.Comments = Comments.text
so.data.Image = Image.text
so.flush()
}
I don't want to create any kind of architecture or server interaction, just append my timestamps and strings to an SO. Screw complexity! I intend to use all 100kb of the SO allocation with pride!
But I have absolutely no clue how to append data to the shared object. (Cough)
Any ideas how I could create a log file out of a shared object? I'll be logging about 200 lines per so it'd be awkward to generate new variable names for each line then save the variable after 4 hours of use. Appending to a single variable would be awesome.
You could just replace your so.data.Title line with this:
so.data.Title = (so.data.Title is String) ? so.data.Title + Title.text : Title.text; //check whether so.data.Title is a String, if it is append to it, if not, overwrite it/set it
Please consider not using capitalized first letter for instance names (as in Title). In Actionscript (and most C based languages) instance names / variables are usually written with lowercase first letter.

How can I reference a Flash file's own filename from actionscript?

In our pipeline, we ultimately publish HTML5 using Toolkit for CreateJS. However one of the steps to get us to that HTML5 includes publishing an SWF that outputs some Javascript code. I've mostly managed to automate this using JSFL. However, at present there is one line of AS3 that our artists have to find on the timeline and change manually, but it interrupts their workflow, and if they miss it or mess it up it is hard to catch, so I would like to automate it too:
Object(root).log.text += " root.skillAnime189 = factory();\n";
From the above, "skillAnime189.fla" is the name of the .fla file which contains this code. This is the case if the artist is working on Skill Animation #189, but if he is doing #304 or #6 or #1022 (no padding) the number changes accordingly, and he has to update that line accordingly.
So, I would like to change that line to something like:
var flaName:String = getThisFlashFileName().split(".")[0];
Object(root).log.text += " root." + flaName + " = factory();\n";
but I am at a loss as to how to access the name of the .fla file containing the code.
The common way to get the swf name is to parse stage.loaderInfo.url parameter:
var url:String = stage.loaderInfo.url;
url = url.split("?")[0]; //remove query string after "?"
var swfname:String = url.substring(url.lastIndexOf("/")+1);
trace(swfname);
output:
astest.swf
But this code gives swf but, rather than fla, so you need to maintain the same names for flas and published swfs (any case usually they are the same, so it shouldn't be the problem)

Loading a movie clip using SharedObject/AS3

Ok, so I'm working on a quiz game for work. I have each question on its own movie clip (I know that's not the preferred method, but it's what I'm most familiar with and a compressed project timeline kinda forced my hand).
Because players will only be able to play the game once (there's a prize involved), I'm attempting to implement a "save/load" system which will allow players to pickup where they left off, in case their browser crashes, they accidentally close the game window, etc. I already have a SO setup to accept save data. So for example, I have the following code on frame 1 of the Q1 scene:
var currentLevel = "Q1"; //first time the var is defined. "Q1" is the name of the scene
answersSO.data.currentLevel = currentLevel;
answersSO.flush();
And I have the following code on frame 1 of the very first scene of the movie:
function checkProgress() {
if(answersSO.data.currentLevel != undefined) {
currentLevel = answersSO.data.currentLevel;
MovieClip(this.root).gotoAndPlay(1, currentLevel);
} else {
gotoAndPlay(2);
}
}
checkProgress();
First, I gotta say that I'm a real nub at AS. I test play the game up to the Q1 scene, then close the window. I restart the game and it instantly skips all of scene 1 and proceeds to scene 2 (which is an intro to the game, not Q1). No error is thrown.
What I'm looking to do is save some data to the currentLevel variable, and save that variable to the SO. At the start of the game, the script should check if the SO has any data in it. If not, then there is no save data—proceed as normal. If there is data, load it and play the last recorded scene the player was at.
I can't figure out (1) how to get this working and (2), of somewhat less importance, why no error is being thrown.
EDIT!
This is my updated code:
stop();
import flash.net.SharedObject;
var answersSO:SharedObject = SharedObject.getLocal("PWFGame"); //DECLARE SO VARIABLE
var currentProgress = "";
//CHECK SO FOR PROGRESS
checkProgress();
function checkProgress() {
if(answersSO.data.currentLevel == null) {
nameField.text = "Enter Name Here";
gotoAndPlay(2);
} else {
currentProgress = answersSO.data.currentLevel;
MovieClip(this.root).gotoAndPlay(1, currentProgress);
}
}
It does work, but the last line in the else statement is acting strangely. It skips over the first scene completely and plays the next scene from frame 1 (which is called "Intro"). Even if I change currentProgress to "Q1" it does the same thing. Why would this line of code work elsewhere and not here?
SharedObjects can be deleted by the user. A player could delete that file and start again.
If there is a login name, you should store that data on the server using a server side script (php, asp, etc.)
So add a check at the beginning and let the user play just if his name has not been stored on the server. Than call this list form flash at the beginning of the game.
For the browser crash, you can store the data only when the game is ended. So when you refresh the page you can start it again.
If there is no username, you should get other data, but it isn't so simple as an IP could change and more important data can't be retrieved by the flash player (you can do it with a desktop application made with AIR).
At the and...
.gotoAndPlay(1, currentLevel);
Remeber that the first value is the scene and the second is the frame.

Ok, after much digging, I've discovered that gotoAndPlay() on frame 1 can cause issues. I moved the updated code block (seen above) to frame 2, and everything works.

Saving and Loading progress in action script 3

I've looked everywhere for this answer..but I am not quite sure on how to do it exactly...
I am making a Flash Game using Flash AS3...
I need options where user can save and load their progress..
can somebody give a step by step on how to do this please? I am very new to actionscript...
usually other tuts shows u how to save certain variables
Cookies!
Lucky us it's very simple. Unlucky us it's not obvious how it's done:
// have that referenced all the time:
var cookies: SharedObject = SharedObject.getLocal("myGameData");
// start saving
cookies.data.progress = 50;
cookies.data.lives = 5;
cookies.data.anyRandomVariable = "my name or something";
cookies.flush();
// now it's saved
// start loading
var progress: Number = cookies.data.progress;
var lives: int = cookies.data.lives = 5;
var anyRandomBlah: String = cookies.data.anyRandomVariable;
// now it's loaded
(following the comments above...)
Yes, pretty much along those lines. I was asking questions to try to get you to see that you do actually have variables/data which you'd save. =b
If you want to save in the middle of the level, it is up to you... I don't know how you've designed your game, but basically you can write the saving code to trigger whenever you want based on any conditions you want.
For saving in the middle of levels, since you are handling the saving and loading you could try having a value like level "7.5" or whatever notation you want to indicate a level that is partway done. Or just use whole numbers like 750 and treat it as a percentage (level 7 at 50% done). And so forth. It's up to you.
A very similar question has been asked how to save a current frame value using a SharedObject. In your case, replace 'current frame' with whatever values you want to save:
