Hey everyone so basically what I am trying to accomplish is saving a number with the Shared Object which the the coins that the player collects in the game and if they player quits out of the game and comes back to play again the amount of coins he had when he quit will still show and he will be able to add to that amount if the player picks up more coins. I had this working for a bit but then the textfield started displaying "NAN".
Here is how I have it set up.
The Variable private var nCoins:Number;
In the constructor function I have:
sharedObjectCoins = SharedObject.getLocal("CoinsData");
nCoins = 0 + sharedObjectCoins.data.tCoins;
if (sharedObjectCoins.data.tCoins == null)
{
sharedObjectCoins.data.tCoins = nCoins;
}else
{
trace("Save data found."); // if we did find data...
loadDataTimeAttack(); // ...load the data
}
and in the games Enter.Frame Loop I have the function saveDataCoins which is setup like so:
private function saveDataCoins():void
{
if (nCoins > sharedObjectCoins.data.tCoins )
{
sharedObjectCoins.data.tCoins = nCoins;
}
coinsGraphic.coinsText.text = " " + sharedObjectCoins.data.tCoins;
sharedObjectCoins.flush();
}
not sure if you need the function to where the hitTest takes place between the coins and player but here it is:
private function checkPlayerHitCoins():void
{
for (var i:int = 0; i < aCoinsArray.length; i++)
{
//get current point in i loop
var currentCoins:mcCoin = aCoinsArray[i];
//test if player is hitting current point
if(player.hitTestObject(currentCoins))
{
nCoins += 1;
updatecoinsTextScore();
updateCoinsPauseScreen();
//Add points sound effects
var coinsSEffect:Sound = new coinsSound();
coinsSEffect.play();
//remove point on stage
currentCoins.destroyCoins();
//remove points from array
aCoinsArray.splice(i, 1);
trace("Hit: " + aCoinsArray.length);
}
}
}
Please if anyone could help me with this maybe point something out that I am doing wrong. This code worked perfect one time and when I closed the screen and came back to re test it the textfield displayed NAN and thats it when I hitTest the coins sometimes the NAN switches to a number for like a second but then goes back to NAN.
The first time (or rather every time it creates a new shared object) you will be trying to add undefined to 0, which will result in either a runtime error or NaN.
You need to check if the value exists before attempting to do addition with it.
if(sharedObjectCoints.data && sharedObjectCoins.data.tCoins && !isNaN(sharedObjectCoins.data.tCoins)){
nCoins = Number(sharedObjectCoins.data.tCoins); //there's not point in adding 0
trace("Save data found."); // if we did find data...
loadDataTimeAttack(); // ...load the data
}else{
sharedObjectCoins.data.tCoins = nCoins;
}
Also, if you don't manually set a value to a number var, it will start off life as NaN. eg var nCoins:Number will be NaN until you set it to something.
That said, working with the sharedObject directly like this is a very sloppy way to code your program. Really you should just use shared object to load and save the value, and everything in between use a strongly typed variable.
var nCoins:int = 0;
var tCoins:int = 0;
sharedObjectCoins = SharedObject.getLocal("CoinsData");
if(sharedObjectCoins.data && sharedObjectCoins.data.tCoins && !isNaN(sharedObjectCoins.data.tCoins){
tCoins = int(sharedObjectCoins.data.tCoins);
}else{
//no shared object, use default value for tCoins
tCoins = 0; //or whatever it should start off as.
}
Then write a save function
private function saveSharedObject():void {
sharedObjectCoins.data.tCoins = tCoins;
sharedObjectCoins.flush();
}
Then replace all other instances of sharedObjectCoins.data.tCoins with the var tCoins
It's probably best not to flush the shared object every frame for performance purposes.
Also, shared objects may or may not actually save, depending on user preferences, storage space available, etc. They should not be relied upon for critical data retention.
You can listen for problems with the shared object with AsyncErrorEvent.ASYNC_ERROR I believe (It's been a while since I've worked with AS3 Shared Objects)

This is the first time I ask in this website, if there's any mistake and inappropriate thing apologize in advance
I was trying to make my own basketball score board using Action Script 3 but I am stuck on the way of calling a player fouls score and show it individually.
In the picture, the second box is where to type a player number who made a foul and the third box is where the number shows how many times this player has fouled.
I need to know how to code an array store that receives a value from the 'Player' textbox as the player number and stores the fouls count with the specific player's number too (if I type another player number it will count a foul separately and next time I type the exist number it will call out how many times he fouls)
You could use an array, or a dictionary, or even dynamic properties.
Let's assume your text fields are called txtTeam1fouls, txtPlayer, txtFouls, txtTeam2fouls. Let's also say you have a var called curTeam that stores an integer identifier for the team whose player number you enter (for this example, either 1, or 2).
Here is an example of storing a basic object in an Array:
var fouls:Array = []; //create a new empty array
//add a listener for when you type something into the player text input
txtPlayer.addEventListener(KeyboardEvent.KEY_UP, updatePlayer);
//this function retries a foul record from the array for a specific player
function getFouls(player:int, teamId:int):Object {
//loop through the array until you find a match
for(var i:int=0;i<fouls.length;i++){
if(fouls[i].player === player && fouls[i].team === teamId){
return fouls[i];
}
}
//if no record in the array, return 0
return null;
}
//this function updates the foul text field when you change the what's in the player text field
function updatePlayer(e:Event):void {
var foulRecord = getFouls(int(txtPlayer.text), curTeam);
//if a foul record exists, use it's foul count, if not use 0
txtFouls.text = foulRecord ? foulRecord.fouls.toString() : 0;
}
//call this function whenever you add a new foul record.
function addFoul(player:int, teamId:int):void {
//first, see if there is an existing foul record in the array
var foulObj:Object = getFouls(player, teamId);
if(!foulObj){
//if there was no record, create one, then push (add) it to the array
foulObj = {team: teamId, player: player, fouls: 1};
fouls.push(foulObj);
}else{
//if there is an existing record, increment it.
foulObj.fouls++;
}
//now update the totals for each team
var team1Ctr:int = 0;
var team2Ctr:int = 0;
for(var i:int=0;i<fouls.length;i++){
switch(fouls[i].team){
case 1:
team1Ctr++;
break;
case 2:
team2Ctr++;
break;
}
}
txtTeam1Fouls.text = team1Ctr.toString();
txtTeam2Fouls.text = team2Ctr.toString();
}
So with TCP in AS3, I'm trying to write strings over to the server and then to the clients, but it appears to only be able to read one at a time. This is not good because I'm sending messages based on keys being pressed, and the client has an action that needs to be taken place based on what key is pressed. Since multiple keys can be pressed at a time, obviously it does not work correctly.
Client example:
if (keys[p1_jump_key])
{
p1_up = "down";
sock.writeUTF("p1_up_down");
sock.flush();
}
else
{
p1_up = "up";
sock.writeUTF("p1_up_up");
sock.flush();
}
if (keys[p1_crouch_key])
{
p1_down = "down";
sock.writeUTF("p1_down_down");
sock.flush();
}
else
{
p1_down = "up";
sock.writeUTF("p1_down_up");
sock.flush();
}
And then here is the server:
function socketDataHandler(event:ProgressEvent):void{
var socket:Socket = event.target as Socket;
var message:String = socket.readUTF();
for each (var socket:Socket in clientSockets)
{
socket.writeUTF(message);
socket.flush();
}}
And finally, here is the recieving client (I have a method that allows the server to differentiate between the two):
if(msg=="p1_down_down"){
p1_down="down";
}
if(msg=="p1_down_up"){
p1_down="up";
}
if(msg=="p1_up_down"){
p1_down="down";
}
if(msg=="p1_up_up"){
p1_down="up";
}
Now many of you already see the issue, as when the down key is up, it sends the message "p1_down_up". When the up key is up, it sends the message "p1_up_up". Both messages are sending at once when neither of them are being pressed. The receiving client is, I suppose, just getting one of the signals, or perhaps neither of them. How do I make MULTIPLE signals get wrote and read over the server? I tried using an array but you can't write those apparently. Thank you.
For anyone else who comes across this like I did trying to figure out how to accomplish this, I have to say that the other solution supplied is highly inefficient, overly complicated and too hard to read. Instead of adding a null byte to the end of your message and pushing packets into arrays, you can simply have the server send the length of the entire message to determine whether the message is in multiple packets, and to make sure you read multiple writes in the correct order.
Here is a working client receive function. I send data as compressed Objects converted to ByteArrays. Objects can store any type of data which make them a good candidate for transferring complex information from server to client.
var messageBytes: ByteArray = new ByteArray;
var messageLength: int = 0;
var readBuffer = false;
function receiveTCP(e: ProgressEvent): void {
while (e.target.bytesAvailable >= 4) {//Loop to see if there is data in the socket that is available to read.
if (messageLength == 0) {
messageLength = e.target.readUnsignedInt();//read the first 4 bytes of data to get the size of the message and store it as our message length.
readBuffer = true;//set the readBuffer to true. While this is true, the function wont be reading any more data from the server until the current message is finished being read.
}
if (messageLength <= e.target.bytesAvailable) {//check to see if our message is finished being read.
if (readBuffer == true) {//Make sure another message isn't being read. Without this check, another incoming message from the server will overwrite the current one from being executed.
e.target.readBytes(messageBytes, 0, messageLength);//reads the byte array into our messageBytes ByteArray declared at the top.
messageBytes.uncompress();//decompresses our message
var message: Object = new Object();
message = messageBytes.readObject();//Writes our ByteArray into an object again.
receiveMessage(message);//send our message to another function for the data to be executed.
messageLength = 0;//reset our messageLength for the next message.
readBuffer = false;//reset our buffer so that the client can read the next message being received, or the next message in line.
} else {
receiveTCP(e);//if there is another message in wait and the previous one isn't finished reading, execute the same function with the same event data again. Eventually the buffer will open and the message will be read.
}
} else {
break;//If the message is split up into multiple packets, this will reset the loop to continue reading the message until all the packets are accounted for.
}
}
}
This will prevent Clogging, allow you to receive multiple messages simultaneously and put together messages that were delivered in multiple packets.
Admittedly, this took a while to figure out. If you need the serverside code for sending the message, let me know.
The TCP protocol consists of a bi-directional stream of bytes, and as such message boundaries are not preserved. Due to this, if you are sending messages too often, you can end up reading from the buffer two messages instead of one.
Thus, some of the messages you are sending might be being processed together, which fails the comparison test on the receiving end.
To fix this, you can append a delimiter at the end of each message. This way, you'll know where every message you sent begins and ends, allowing you to split and process them separately. This also means you don't need to flush after every write to the buffer.
For instance, you could use a null byte (\0) as delimiter.
if(keys[p1_jump_key])
{
p1_up = "down";
sock.writeUTF("p1_up_down\0");
}
...
sock.flush();
And on the receiving end, we trim any trailing delimiters and then split the message into the smaller packets.
EDIT: Fixing the issue you described gives rise to another one: your messages might be being split over two buffer reads. I've edited my code to reflect a solution to this, by creating a temporary variable where partial messages are stored, to be prepended to the other part(s) of the message in the following reads.
// First we check to see if there are any 'parts' of a message that we've stored temporarily from the last read. If so, prepend them to the message string, which must be its continuation
if(temp != "")
{
msg = temp + msg;
temp = "";
}
// Now we begin processing our packet
var splitPackets:Array = msg.split("\0");
var packets:Array = new Array();
// Deal with incomplete message reads
if(splitPackets[splitPackets.length - 1] != "")
{
// If the last item in our array isn't empty, it means out message stream ended in a partial message. Hence, we have to store this value temporarily, and append it on the next read of the stream
temp = splitPackets[splitPackets.length - 1];
}
// If the last item in our array is empty, it means our message stream ends in a full message
for(var i = 0; i < splitPackets.length - 1; i++)
{
packets[i] = splitPackets[i];
}
for(var i = 0; i < packets.length; i++)
{
if(packets[i] == "p1_down_down")
{
// Process each packet individually here
...
// If you have already processed the packet, move on to the next
continue;
}
// Processing code for other packets
...
}
Hope this helps!
I've spent nearly 1 week to learn working with objects instead of arrays. I had thought it was easy to call them and created some objects and set their properties. However I can't access them now, I tried this:
function onBoxClick(event:MouseEvent):void {
var str:String = event.currentTarget.name;
trace(str);
str = str.substring(str.indexOf("_") + 1);
trace(getChildByName("copy_" + str)); // trying to trace an object by name
}
My question is if there's a practical way of dealing with objects, otherwise what's the purpose of using them.
Edit: Here's my function that I use to create movieclips and other things:
function addBoxes(isUpdate:Boolean):void {
var copyOne:Object = getReadOnlyValues();
copyOne.name = "copy_" + num;
// Set default mc1 settings
var settings1:Object = copyOne.mc1Settings;
for(var num2:String in settings1) {
copyOne.mc1[num2] = settings1[num2];
}
// Set default mc1text settings
var settings2:Object = copyOne.mc1TextSettings;
for(var num3:String in settings2) {
copyOne.mc1Text[num3] = settings2[num3];
}
copyOne.mc1.x = nextXpos;
copyOne.mc1.name = "captionBox_" + num;
addChild(copyOne.mc1);
copyOne.mc1.addEventListener(MouseEvent.CLICK, onCaptionClick);
copyOne.mc1Text.name = "captionBoxText_" + num;
copyOne.mc1.addChild(copyOne.mc1Text);
// ---------------------------------------------------------------
// Set default mc2 settings
var settings4:Object = copyOne.mc2Settings;
for(var num4:String in settings4) {
copyOne.mc2[num4] = settings4[num4];
}
// Set default mc2text settings
var settings5:Object = copyOne.mc2TextSettings;
for(var num5:String in settings5) {
copyOne.mc2Text[num5] = settings5[num5];
}
copyOne.mc2.x = nextXpos;
copyOne.mc2.y = copyOne.mc1.height;
copyOne.mc2.name = "box2_" + num;
addChild(copyOne.mc2);
copyOne.mc2Text.name = "box2BoxText_" + num;
copyOne.mc2.addChild(copyOne.mc2Text);
copyOne.mc2.addEventListener(MouseEvent.CLICK, onBoxClick);
if (num / subunits is int) {
trace (num);
// createMc("normalBox", true);
}
nextXpos = nextXpos + copyOne.mc2.width;
// traceObj(copyOne);
// traceObj(getReadOnlyValues());
}
I called this function in a loop so I created many movieclips. Now I can't access objects' properties and their childen (e.g textfield).
Objects I have on stage: Movieclips and textfields
Where they come from: The function above
What I'm trying to do with them: Tracing movieclips and textfields (that are holded by objects) to change their children (textfield) text
What happens instead of what I expect: Trace code outputs undefined instead of giving me object type trace(getChildByName("copy_" + str)); // trying to trace an object by name
Is there a practical way of accessing an object whose name is "copy_1" and its property whose name is "box2_1" (movieclip)?
One problem I see is the "copyOne" object has been created within the scope of "addBoxes", so it will no longer exist outside of this function.
Another is you're trying to access an Object via getChildByName, which only addresses displayObjects of the displayObjectContainer you are calling from.
If you want to loosely keep track of variables with things like Objects or MovieClips (which are both dynamic-style objects that let you add properties to them as you wish), just use MovieClips to house your values. The movieClips, being on the stage, will be retained in memory until removed from the displayList (stage).
Also, check out the Dictionary, a sort of key/value based way of storing collections of objects.
Better yet, if you use strongly-typed custom objects (creating your own classes to extend MCs, and adding your own public or private methods and values), there are benefits such as using Vectors (fancy, fast arrays that are compatible with any Object type you choose).
I don't really know if I understood your question or not, but as #ozmachine said in his answer, you can not use getChildByName, instead I think that you can take a look on this, may be it can help :
var container:DisplayObjectContainer = this;
function getReadOnlyValues():Object {
return {
mc1: new box(),
mc1: {
name: 'mc1_',
alpha: 1,
x: 0,
y: 0,
width: 30,
height: 25
},
mc1Text: new TextField(),
mc1Text: {
text: 'test',
x: 0,
y: 0,
selectable: false,
multiline: false,
wordWrap: false
}
}
};
// create 5 objects
for(var i=0; i<5; i++){
container['copy_'+i] = getReadOnlyValues();
var obj:Object = getObjectByName('copy_'+i);
obj.mc1.alpha = 1;
obj.mc1.x = 0;
obj.mc1.y = 50 * i;
obj.mc1.width = 100;
obj.mc1.addChild(obj.mc1Text);
obj.mc1Text.text = 'test_' + i;
addChild(obj.mc1);
}
// get object by name
function getObjectByName(name:String):Object {
return container[name];
}
// change the text of the 4th button
stage.addEventListener(MouseEvent.CLICK, function(e:MouseEvent):void {
var obj:Object = getObjectByName('copy_3');
obj.mc1Text.text = 'new text';
})
Array and Object are both data structures.
Data means some form of information.
Data structure means some form of information being stored in a certain way.
Array and Object are two different ways to store information.
Arrays identify data with integer numbers.
An integer number to identify a single element of an array is called an index
Arrays are ideal to represent a list of similar things that belong to each other.
var names:Array = ["John", "Paul", "George", "Ringo"];
This often means that the elements of an array are of the same type, like in the example above.
But they don't have to:
var numbers:Array = [42, "twenty-five", "XIIV"];
For the above examples it's easy to answer the questions "What are the names of the four beatles?", "What different representations of numbers did you stumble upon during your trip through the historic town?". Other questions are harder or impossible to answer. "What Roman numerals did you stumble upon in the historic town?"
Objects identify data with names.
A name to identify a single element of an object is called a property
Objects are ideal to represent a list of dissimilar things that belong to each other.
var paula:Object = {age:37, name:"Paula", hairColor:0x123456};
This often means that the elements of an object are of different type, like in the example above.
But they don't have to:
var car:Object = {manufacturer:"Porsche", color:"red", sound:"wroooooom", soundOfDriver:"weeeeeeeeeeee"};
Considering this, let's take a look at your code and see how it applies.
The big picture is that you have a function addBoxes that you call multiple times. As one function should have one purpose, this function will do something similar every time it is executed. Uh-Oh: "similar". Whatever the result of this function is, it should go into an array. Each call to that function would be an element of the array. You can see this clearly on your use of "num" to identify whatever is happening in your current run of the function.
What data is present in your function?
copyOne
mc1
mc1Text
mc2
mc2Text
copyOne is a troublemaker here and what causes your confusion. It's trying to do everything at once and therefore you are not able to think clearly about when to use a Array and when Object. One would call it a god object. And that's not a good object to have around.
Your choice for variable names is very bad.
You choose super generic names like "mcX" only to later add a name property to it that describes what it truly is.
But even that doesn't hold true for whatever "Box2" is supposed to be.
Choose names so that it'S easy to understand what something in your code is.
It looks like you created all or parts of this structure jsut for this question and therefore lacked meaningful names.
I highly recommend that you do not learn by such made up projects. But from the real world.
I will therefore impose the following goal:
mc1 and mc1Text represent a caption
mc2 and mc2Text represent a content
With all this, I ask again:
What data is present in your function?
captionBox
captionText
contentBox
contentText
Both caption and content consist of a box and a text.
These are different things, so caption and content are each an object with properties "box" and "text"
One could think that due to this similarity, they both should go into an array.
But I beg to differ. A caption and a text are not the same thing. You deal with captions and texts differently. Walking on the streets you might catch a big caption in the news quickly, but not a lengthy text. That's why each of them should be a property of the object that's created in the function.
Here's somewhat of a conclusion:
var allBoxes:Array = []; // array to store the similar results of every function call
function createBoxes():void
{
var boxes:Object = {};
//the box consists of caption & content, both bying of the same type, but are containing different data
boxes.caption = {box:{}, text:{}}; //caption
boxes.content = {box:{}, text:{}}; //content
allBoxes.push(boxes);
}
This is it. That's how and why I would model your data with objects and arrays.
But it doesn't end here. My conclusion lacks a lot of the code you posted.
While the above is mostly language independent, the missing code is specific to Actionscript and not just on how to model data. It's as follows...
As3 is object oriented.
This is good, because the above conclusion has a lot of objects in it.
To define how some object is/does/moves/farts/etc, one creates classes.
The following changes take place (for reasons out of the scope of this answer):
createBoxes (formerly known as addBoxes) calls the constructor of
a class "CaptionAndContent" that extends Sprite.
There's no more need to explicitely create an object "boxes" as the constructor does exactly that.
The caption and content will not have a property "box", because
they can be the box themselves. This is exactly how it's done in the
code of the question. The default settings are set in the constructors of their classes.
Here's reduced snippet of code that hopefully illustrates how the classes could look like.
Each class should be in its own file, with the necessary imports, package block and the additional functionality that you did not specify in your question.
public class CaptionAndContent extends Sprite
{
private var caption:Caption;
private var content:Content;
public function CaptionAndContent(captionText:String = "", contentText:String = "")
{
caption = new Caption(captionText);
addChild(caption);
content = new Content(contentText);
content.y = caption.height;
addChild(content);
}
}
public class ClickableBoxWithText extends Sprite
{
protected var textField:TextField;
public function ClickableBoxWithText(text:String = "")
{
textField = new TextField();
textField.text = text;
addChild(textField);
addEventListener(MouseEvent.CLICK, onClick);
}
protected function onClick(mouseEvent:MouseEvent):void
{
//override this in a sublclass
}
}
public class Caption extends ClickableBoxWithText
{
public function Caption(text:String = "")
{
super(text);
// apply all the default settings of caption here.
}
}
public class Content extends ClickableBoxWithText
{
public function Content(text:String = "")
{
super(text);
// apply all the default settings of content here.
}
}
Using them would look something like this:
var allBoxes:Array = []; // array to store the similar results of every function call
function createBoxes():void
{
var captionAndContent:CaptionAndContent = new CaptionAndContent("This is the caption...", "...for this content");
captionAndContent.x = nextXpos;
addChild(captionAndContent);
allBoxes.push(captionAndContent);
}
Last but not least, the identification problem in the click handler.
Your question already contains the answer:
event.currentTarget
That's the reference to the object that was clicked on.
In my code it would be
mouseEvent.currentTarget
This identifies the object already. It's pointless to look up one of its properties (its name for example) in order to search all the objects for that name, just to identify the same object that you already had to identify (without a name) in order to get the name.
You aren't identifying the objects by name anyway. What differs between the names and what supposedly makes them unique is a number at their end. As pointed out in this answer, this is what's called an index and the thing you are trying to identify with it should go into an array. In my example codes, this is allBoxes.
I'm trying to get the music properties for each file in the music library by using the StorageFolder APIs.
After calling GetFilesAsync(CommonFileQuery::OrderByName) on my music library I'm iterating over the resulting IVectorView^ and calling StorageFile->Properties->GetMusicPropertiesAsync() for each file, which is inherently slow but I have to do it this way, since QueryOptions are not supported on Windows Phone for some reason.
Anyway, after completing that task every property is correct except for MusicProperties->Year, which is 2014 for every single one of well over 900 music files on my phone. Here's a short code snippet:
create_task(lib->GetFilesAsync(Search::CommonFileQuery::OrderByName))
.then([](IVectorView<StorageFile^>^ songFiles)
{
auto taskPtr = std::make_shared<std::vector<task<Song>>>(songFiles->Size);
for (size_t i = 0, len = songFiles->Size; i < len; ++i)
{
StorageFile^ song = songFiles->GetAt(i);
(*taskPtr)[i] = create_task(song->Properties->GetMusicPropertiesAsync()).then([]
(MusicProperties^ props)
{
Song s;
s.album = std::wstring(std::move(props->Album->Data()));
s.artist = std::wstring(std::move(props->Artist->Data()));
s.title = std::wstring(std::move(props->Title->Data()));
s.track = props->TrackNumber;
s.year = props->Year;
return s;
});
}
//further processing is done in a when_all function after the song tasks have completed
}
Song is just a plain struct to save my result temporarily and convert it to JSON later on, but that Year property is freaking me out. Has anybody else encountered that issue already and is there any other way to retrieve the proper release year from a music file?
I made an invetory in AS3 which allows me to put items on slots in a closet, or in slots in the inventory. It completely works, but there is one problem.
In the game you are supposed to be able to buy new items and add them to the closet. I want this to be saved so that it is available the next time you play.
To do this, I want to save an Array to a SharedObject, then create the items dynamically from the array.
Right now I'm using the old fashioned hard coding for each object;
Itemwrench = new WrenchItem();
Itemwrench.x = par.toolCloset.kast_1.slotTC1.x + 400;
Itemwrench.y = par.toolCloset.kast_1.slotTC1.y + 245;
Itemwrench.gotoAndStop(2);
Itemwrench.name = "slotTC1";
Itemwrench.TC = 1;
NotinventoryParentTC.addChild(Itemwrench);
However, to add them dynamically I'd have to use getChildByName before it is added to the stage, which is not possible.
If possible could you show me how to do this correctly?
The information you need:
-The items are all stored in a closet with slots(Instances in the closet movieclip).
-The items need to get the name slotTC + the integer in a for loop.
-The name of the items change according to the slot number they are assigned when you take them out of the closet or put them back into the closet.
for(var i:int = 0; i < itemsInTC.length - itemsInTC.indexOf(e.currentTarget.name) - 1; i++)
{
nextSlotTC = "slotTC" + (itemsInTC.indexOf(e.currentTarget.name) +2 +i);
trace("Next Slot: " + nextSlotTC);
TempStrTC = "slotTC" + (itemsInTC.indexOf(e.currentTarget.name) +1 +i).toString();
trace("temp string: " + TempStrTC);
NotinventoryParentTC.getChildByName(nextSlotTC).x =
par.toolCloset.kast_1.getChildByName(TempStrTC).x + 400;
NotinventoryParentTC.getChildByName(nextSlotTC).y =
par.toolCloset.kast_1.getChildByName(TempStrTC).y + 245;
if(Boolean(NotinventoryParentTC.getChildByName(nextSlotTC)))
{
NotinventoryParentTC.getChildByName(nextSlotTC).name = TempStrTC;
}
}
This way I assign a new name and place them in the slot with the new name they received.
So now my question:
How do make it so that you can save the items to a shared object so that they are in the closet the next time you play the game.
Sorry for the long question.
Thanks in advance,

You cannot directly store a DisplayObject in a SharedObject, as it contains memory links which will not be valid if you load such an object. A comon way to work around this is to store a significant data portion of that object. For example, you devise a following structure:
class SlotStructure {
public var slotID:int;
public var itemID:int;
public var itemName:String;
public var itemParameters:Array; // stuff simple types here
}
Then, for each of your items in inventory, you generate a SlotStructure object describing a particular inventory object. For your wrench it could look like this:
var ss:SlotStructure=new SlotStructure();
ss.slotID=1;
ss.itemID=getID(item); // assuming a function that returns a type of an item
ss.itemName=item.name;
ss.itemParameters=new Array();
for (var param:String in item) ss.itemParameters.push({name:param,value:item[param]});
Then you store an array of these into your SharedObject. To retrieve an inventory from a SharedObject you do:
public static const
registerClassAlias("SlotStructure",SlotStructure); // to be able to typecast from SO
for (var i:int=0;i<slots.length;i++) {
var ss:SlotStructure=slots[i];
var item:Item=new getClassFromID(ss.itemID)(); // a function that returns class
// say 1 - wrench, 2 - short sword, 3 - long sword, etc, one type=one ID
for each (var o:Object in ss.itemParameters)
item[o.name]=o.value;
placeIntoSlot(item,ss.slotID); // this does manipulation with x&y and display
}
A function getClassByID() might look like this:
private static const CLASSES:Array=
[StoneItem,WrenchItem,ShortswordItem,LongswordItem,...];
// manually stuff all your items in this!
public function getClassByID(id:int):Class {
return CLASSES[id];
}
The entire solution can be tailored to particular task, for example, in my game I have gems, that differ by location, type, size and score, so I store just these values and then I create new gems, set location, type, size and score with one function that sets all the other relevant parameters of that gem to align with stored info, and call it after making a gem with new Gem(). Your items might too be only worthy of a class name and ID in the class table, so store these with slot numbers and create objects that will have all their properties already set.
