Actionscript 3 :: Track X And Y Values Of Multiple Object Instances On The Stage?
Oct 27, 2011
I have an arbitrary number of object instances on the stage. At any one given time the number of objects may be between 10 and 50. Each object instance can move, but the movement is gradual, the current coordinates are not predictable and at any given moment I may need to retrieve the coordinates of a specific object instance. Is there a common best-practice method to use in this case to track object instance coordinates? I can think of two approaches:
I write a function within the object class that, upon arbitrary event execution, is called on an object instance and returns that object instances coordinates.
Within the object class I declare global static variables that represent x and y values and, upon arbitrary event execution, the variables are updated with the latest values for that object instance.

I have a movieclip that gave a class name and set everything to export into action script. Now, I would like to put multiple instances of that same movieclip on the stage. I would also like to be able to keep track of them individually. Would I need to do something like create a for loop and have it run however many times i want that movieclip onstage? If I did that, how would I be able to manage them? Would I also give them names in the for loop and have a var that goes ++ every time it loops, then attach that var to the end of the name I give it.

I understand how to import a swf and add it to the stage. Is it possible (using code) to add the one imported swf to the stage multiple times, each with different instance names? So the same as adding a library item to the stage multiple times, each time with a different instance name, with code, but using an imported swf?

I'm creating a game in ActionScript 3.0 using the FlashPunk game engine and the FlashDevelop SDK. I've created my own MovieClip class that takes a preloaded movie clip file.
public function MyMovieClip(file:MovieClip, posX:int, posY:int, frameRate:int)
{
movieClip = file;
[Code]....
The problem that I'm having is that when I have multiple instances of the MyMovieClip class using the same swf file, only the last instance is rendered and is updated for each instance of the class that I have.(e.g 3 instances of MyMovieClip, the last instance is updates at 3 times the speed.)

I'd like to create a chain of objects (either movie clips or sprites) that move left to right across the stage continuously. I know I can create two movie clips that contain a series of several 'chain links' and are each a little wider than the stage width. Then I can move both clips across the stage and when the first movie clip is completely off stage reset its x position back to 0. Likewise, when the second clip is completely off the stage on the right, reset it's position off the stage to the left.
This works and gives me the basic effect that I want by creating this uninterrupted moving chain, but it doesn't seem like its the most efficient way to achieve this. What I thought would be more efficient would be to create each link in the chain separately from an individual mc in my library by programmatically adding new instances to the stage.So, I created a single chain link mc and set its export linkage to 'Link' and left the base class to flash.display.MovieClip. Next, I placed the following snippet of the code on the first frame of my movie:
Code:
var xPos:int = 0;
var yPos:int = 100;

i have 4 flvplayback components on stage loading 4 different videos. How do i sync them?
I have ensured they are all fully buffered i.e fully loaded and then play them all at once. But they keep getting out of sync. I.e i am checking the sync with the playheadtime. I had written an timer/enterframe event to check for out of sync at and pause and seek times to the fastest playing player . But this happens for every second. i keep gettting a very jittery video with breaking sounds due to the constant pause /seek / play cycle.
How can we sync multiple flvplayback videos properly.

I'm having issues with something wanted to accomplish involving qued amations that i can reuse in various situations throughout an application...
Basically, what I'm trying to get is a prototype or function that will allows for multiple instances on that stage that start at a specific x/y and size, animate to a specific x/y size and end at a specific x/y and size... the x/y and size information is defined for each of the instances in the function.
A good place for this would be with buttons... check the sloppy diagram attached.

Ive gone through the Object-Oriented Scrollbar tutorial on [URL]. Its working great and I have multiple buttons inside of the moveclip it lives within. The problem occurs when I create another one on the same page. I have put one on frame 1 and the other on frame 5 so that I can select a 'category' and the scrollbar movieclip changes to the relevant buttons.Ive duplicated the movie clips and changed the instances accordingly. I keep getting these errors in the Output panel when playing my swf;TypeError: Error #1009: Cannot access a property or method of a null object reference. at as3_movieplayer_fla::MainTimeline/frame1()and when I click the like to the second category it comes up with this error;TypeError: Error #1009: Cannot access a property or method of a null object reference. at as3_movieplayer_fla::scrollbox_1/thumbUp()Not really sure what im doing wrong - or even what these mean!Here is the code from my main actions layer;

i would like to place various instances of the same library object on the stage.
the different instances (0,1,2,...) are meant to be containers for their individual content. hence, each instance (0,1,2,...) is one container and each containter embeds different placeholders (textfields- and image-instances) in itself.

I'm using this AS to load multiple external images into mc instances on a stage, using different loaders.[code] The external images always load from the upper left corner down, how can you make the image load from the center of the instance on stage?I found this code below and doubt it will work for me since I have 5 mc instances on different parts of the stage, so the stage wouldnt be a good reference point.[code]

add multiple instances of an object to the stage at different but not random points.
For example - I have a box that is linked to a class file. In the class file I have an "ADDED_TO_STAGE" event listener. The function that is called places the box at a certain position on the stage say.... x=100, y= 200.
In the document class I create an instance of it like so -
_box:box = new box();
addChild(_box);
Now what I want is to create multiple instances of box on the stage every 5 seconds. But I don't want them all to spawn at (100,200) on the stage. But here's the catch, I don't want them to be random spawns either.
for ex- I want the first instance of box to spawn on (100,200), then 5 seconds later, the second instance to spawn at (200, 800), the third at (100, 500) and so on.
Would it be possible for me to create objects on the stage to serve as reference points for where i want the instances to spawn instead of writing the exact co-ordinates?

I thought this would be simple but for some reason I'm having all kinds of problems. Why won't the for loop create a new c instance each time the loop increments, like it does for sHolder and s? ...And, assuming it is possible to make it do this, how can each instance be given an identifier that can be accessed dynamically, like sHolder and s in the traceSomething function?
Code:
package {
import flash.display.Sprite;
import flash.geom.ColorTransform;

I am working on an RPG-type game, and in this game I've defined multiple objects for characters, named char1, char2, etc, then assigned the objects values such as Health, Magic, Strength, etc. I then created a dummy object with all of these same values, except every value is set to zero. There are some 30 values in every object.
I would like to see if I could do something like:
Code:
dummychar = char1;
to transfer all of the values from char1 to dummychar instantly without having to define every value transfer, however, I can't seem to find the correct bit of code, because doing the above seems to erase all the values from the dummychar object completely.
The point of this excersize is the make the dummychar object a placeholder so I can switch char1 with char2, meaning char1 would take char2's place, and vice versa. The dummychar object will hold the values for char1, then char2's values will overwrite char1's values, then the dummychar's values will overwrite char2's.
So, in pseudocode:
Code:
dummychar = char1;
char1 = char2;
char2 = dummychar;
My current way of doing this includes telling every single value in the char objects to transfer, but that takes up quite a bit of coding space, and I was wondering if there is an easier way.

As stupid as my question might sound, i have spent the last 2 weeks reading oop books; but could use some guidance. I have a flash project that is basically a supped up slide show. On the stage i have the following: main_mc (instance name = images_mc) = movieclip which holds "pictures" ui1 (instance name = ui1_mc) = user interface that allows user to draw on picture (when drawing is enabled) ui2 (instance name = ui2_mc) = activates invisible hit areas (buttons) on select pics, when hit area is clicked, we jump to another pic in the main_mc.
I accomplished all of this on the timeline, but am updating the code to OOP. I am having A HELL OF A TIME trying to figure out how to store references to the instances (images_mc etc..), so i can control them from varying class files. I have found it is easy to control the instances from the documentclass, but not from unrelated class files. Example: images_mc.stop(); works in document class; but ovieclip(Parent).images_mc.stop() doesn't seem to work from any class file.(ui2 class file for example);

Ok so here is my XML slideshow Actionscript:
ActionScript Code:
stop();
var xmlRequest:URLRequest= new URLRequest("graphicImages.xml");
var xmlLoader:URLLoader = new URLLoader(xmlRequest);
[Code]....
So I figured that the coding of separate scenes would work independently of one another, but I guess I was dead wrong, because when I apply this to a different scene and change the XML path for a different set of images, I get all sorts of conflict errors when I test the entire movie. I have my flash film set up so that each link send the user to a different scene, which plays a unique intro for each, and then the slideshow appears on screen and the viewer can navigate the images.
Is there a work around for this? Or am I going to have to break my flash movie into separate movies? Or should I just add a suffix to all my vars and functions so that they are unique for each scene?

I'm currently stumped by this. I've created a class to load xml data from a txt file, then assign that xml to a variable named siteStructureXml. When I trace the value of siteStructureXml from within the class instance it shows the expected xml data. When I try to assign the value to a variable returnedXml defined on the timeline of my movie, it's value traces as null. I've a feeling it's something blindingly obvious..

I am trying to create a Flash application(more like a game) where a user can add sounds to a timeline and then play the resulting "song". That is not really hard to do, and the resulting track can be saved and played within my app, but the problem is that I would like to export the created track as a .wav(or .mp3). I know that recording from a microphone with MicRecorder is possible and then the record can be exported with WaveEncoder, but I didn't find a way to create a custom sound stream from multiple sounds and than export it.

Using the for loop i create many buttons and add events to them;
[AS]
for (var j:Number = 0; j < all_objects.length; j++) {
var dump = new Sprite ;
dump.graphics.beginFill (0x41C5D2,.5);// flash button color default=0x41C5D2[code]....
I need to know which button is pressed, so i use the (tricky) unprofessional methode: event.target.name.the question is; how can I know which button is pressed, using a custom event, this custom event should pass some vars to the called function, including the j var (from the loop)actually I tried setting a custom event using the example at the noponies accordion menue class, but it's so complicated to get working.

When I use the following code, I'm able to track the stage size within the browser. But what I don't understand is that when I use StageScaleMode.SHOW_ALL instead, the reported height and width of the stage is always fixed at 1920 x 1080 (my stage size in Flash authoring) no matter how small I bring the browser into.

how subclasses,instances,and inheritance work. The below code isn't actual project code, it's theoretical code, generalized to a simplistic level so that we can talk about the big issues.Let's say I have animals_app.fla, with a "Dog" class MC and a "Cat" class MC. Both "Dog" and "Cat" are subclasses of "Animals"; animals_app.fla uses document class "Main".
Intuitively, I think Animals should declare that every subclass should have some animalSpecies, and each subclass will define the value of its own animalSpecies. It wouldn't make sense for Animals to provide any default value, because it will always be different per subclass. Is this correct? I had tried out some code similar to that below, and was perplexed because it seemed like whenever a subclass tried to define a value for its own animalSpecies variable, it was actually changing the value of the variable in the Animal class, but that's not what I want. How do I rewrite this code so that each subclass defines the values of variables it inherits from its superclass, without altering the superclass? And how would I define the value of variables for each instance of a class, so that I'm only changing the values of that instance, without altering the subclass?
Animals.as
Code:
package
{
import flash.display.MovieClip;[code]..........
Also, conventionally, what should be in my Main class? Only the addChild code which attaches MCs to the stage? Or should the values of variables be defined in Main? What am I missing? I recently read Foundation Game Design with Flash and didn't feel like the explanation was sufficient. I've tried scouring the web for OOP tutorials, but they're either too basic or too far over my head.where I should be defining values of variables for classes, subclasses, and instances?

I am currently trying to create a piece of code that will retrieve values from a 2D array and use them as x and y values to position instances of a MovieClip called mcMain. The code for the array will look something like this...
Code:
var lvlMain:Array = new Array();
lvlMain.push(new Array());
var xAxis:Array = new Array([150,400,200,300,100]);
[Code]....
how to create a piece of code that would retrieve the x and y coordinates listed in the arrays and use them to create instances of mcMain. So going from the code above it would create the first instance at x=150 and y=100, second instance........fifth instance at x=100 and y=500.

I know we can track when the mouse has left the stage area in AS3.
But, can it reset a button that would have stayed in its "on" state?
My swf will be embedded in a web page, there are 24 buttons all around its border, and as soon as the mouse leaves the stage, they stay "on", so I want to reset them to the initial state.
