ActionScript 3.0 :: Copying Arrays Back And Forth?
Jul 20, 2010
I am working on a program with a number of particles that fly around and can collide with each other.I keep all of them in an Array named "particleArray" However, when a collision occurs, I want the two colliding objects to be deleted, and 1 new one formed in their place. I can't do this with just one Array because it affects the order/length of the Array while it's still running through a for loop.
i'll just create a temporary array, make that a copy of the master array, make the changes I need to that one, and then when the master array isn't being used, I can copy the contents of the temp array back into it to be used for the next frame.However, flash doesn't seem to like this. I've tried splice/slice/and concat and get various errors. All the tutorials for copying arrays involve creating a new array and setting it equal, but I need both arrays to be persistent and global, only created once. Do I have to create a for loop to manually copy between the two?
flash hates this code, that I thought would be simple and work:
particleArray = particleArrayRefresh.splice(0); // empty the temp array into the main one.
All similar things i've tried have failed as well. It doesn't seem to want to set an EXISTING array in this way, but I really don't want to use an innefficient for loop to tax each computation cycle more.

This is probably something really simple but I have this multi-dimensional array which holds vital data. At one point in my program I need to copy the array so that I can sort it numerically and display the data, without permanently altering the original array order. I thought okay, create a new array and copy the original array data into it.[code]...

- I tried, when I first started making this site, to load all of the artwork images into an array and then copy the array before resizing them for their specific functions (being seen as thumbnails or as full size pics.) Unfortunately, I ran into the well known issue of Array cloning only creating a pointer to the same group of items. I tried the newArray = oldArray.slice() trick, but it didn't seem to work. Finally, I just loaded the images twice into two separate arrays, and it works, but I hate this solution. Anyone got a better one?
- I'm trying to maintain some sort of connection between the two sets of Arrays so that, for example, when someone clicks on Thumbnail 15, Fullsize Image 15 will open up but I couldn't find anything that worked. Renaming the Instance Name dynamically didn't seem to work and adding an Instance Variable dynamically doesn't seem possible either as I can't make the Class I am working with (Sprite, in this case) dynamic ahead of time. I'm sure there's a simple method for this.opens up, the different animations seem to interfere with each other and slow each other down (they also seem to get interference from the time taken to load the image Arrays.)

how to use an array to create a back button for something I've made in Flash. I wish it was as easy as making the back button go to the previous slide, but there are several branching scenarios where that scenario won't exactly work. I purchased a membership to Lynda.com in order to try and learn AS3, but the section they have on arrays in AS3 doesn't come close to teaching me what I need to know for this kind of operation.

I am running into some trouble adding an array into another array to create a multi-dimensional array.The code appears as below:
var slideDataArray:Array = new Array();
var slideShowDataArray:Array = new Array();
slideDataArray[0] = xmlData.SlideShowParameters.SlideShowImagesDirectory;[code]........
I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.

I've got a bit that loads a big chunk of xml data about products.I push product info into an array(e.g. productArray), then add that array to another array (e.g. allProductsArray)How do I sort those arrays? For instance, if I want to sort the allProductsArray based on the info in productArray[0]?Alternatively, would something other tha an array of arrays be a better route?This loader loads the same sort of info for many different clients, so the bit to sort on will change.

I'm trying to write a function where I can specify any amount of array, and the return value will be an array containing the contents of all of the specified arrays.I've done this, but it seems like a really slow and ugly way of doing it:
var ar1:Array = [1,2,3,4,5,6,7,8,9];
var ar2:Array = ['a','b','c','d','e','f','g','h'];
function merge(...multi):Array[code].....
Is there an inbuilt and more efficient / nice way of achieving this? The result does not need to be in the same order as the input - completely unsorted is fine.

A little explanation: Im making a random arranging number Array. So instead of using a loop and assigning 0 to first array element, 1 to second, etc.I need to make it totally random but without repeating any numbers. To do that I made a second Array that will have the same number of children to serve as a reference.Each of them will be an Object with a property "num" , wich will be its actual number, and a property "called" wich defaults to false.Like this:
ActionScript Code:
for(var i:int=0;i<vQuantity;i++){
ranArray.push( new Object() );

I've had a problem for awhile that was really odd. After some intense debugging, I realized the problem lied in setting an array equal to another array.[code] When setting one array equal to another, the values aren't copied over, but a reference to that memory is stored. So no matter which variable you change, they are both references to the same memory and thus both will reflect the changes.With other data types, this doesn't happen.I could fix it by looping through t1 and using push() to add each index from t1 into t2, but that seems a little messy.

correct syntax for pushing variables to arrays within arrays? I have searched many threads but found nothing that exactly answers my query.I have a class (Brigade) which amongst other variables contains an array (BrigadeUnits) This is the third element.. My Brigades are stored in an array called AllBrigades. I now need to fill the BrigadeUnits array with objects of my Units class.The hierarchy I want to create is as follows:
AllBrigades (array of Brigades)
Brigade (object)
BrigadeUnits (array within Brigade object)
Unit (Object to be stored in BrigadeUnits array)
I have tried various approaches including the following, assuming that I am addressing the first Brigade in the array:
AllBrigades [0] [2].push (MyUnit);
But when I trace this I just get undefined.

I have a Flash website with 3 interfaces( 3 frames with movie clips inside). they have a button that goes to different loaded .html page(text). But once the back button is pushed on the web browser, it always goes back to the first frame instead of the actual last page, which might have been frame 2 or 3.

Anyways I am using action script 3.0 and I created multiple layers using just one scene. I created a layer with lables on them to mark where I want my buttons to point to and go to. I have the stop (); on the first frame. And I made my buttons mostly interactive with movie symbols and tweens.My first scene I have 2 doors, the user can pick which door to go to and it takes them into a different path.I made the buttons that are clicked to go forward, and then I tried to make an invisible button on the button edge of the scene to go backwards However, the PROBLEM is when I click my button to go backwards I am stuck on the first page and can't move forward.
function gotoOne(evt:Event):void{ gotoAndStop("one")}backbutton1.addEventListener("click",gotoOne);
function gotoFour(evt:Event):void{

I am working on a having external swfs get loaded into the main swf one by one from an array.I can get the first one to load, but it just keeps on playing the first item in the array over and over, instead of loading the next movie. I have a container on my stage, cleverly named "container" and I am using AS2 and loadMovie.
I am guessing my conditon on my if statement is off, but I am not sure how to tell the onEnterFrame to check the currentframe of the loaded swf and not the container itself. I might be way off, but in my mind I feel like this mostly makes sense, but knowing Flash it is probably not nearly enough coding.I might also add this won't be running on the web, so I don't need to worry about preloading swfs since it will be running directly off a PC onto a screen in our office.Here is my code:
Code:
var myClips:Array = ["movie1.swf", "movie2.swf", "movie3.swf", "white_logo.swf"];
var i:Number = 0;
_root.container.onEnterFrame = function() {[code].....

I've got the standard scene 1 with three frames on it. the first frame has a movie clip with about a 70 frame timeline. the second frame has a movie clip with about a 20 frame timeline. the third frame is black with a stop action. i'm trying to make a leaderboard banner, and i need each clip to play one after the other.
right now, when ctrl+enter it plays nothing. i actually have to rewind it to have it play the first clip. then it just repeats the first clip and completely skips the second. in the first clip's timeline, I have a parent.gotoAndPlay(2); on the last frame.

i am happy with it and now want to repeat it with all the other images in the slideshowhe problem is, when i copy the keyframes (with a tween) on the first image that animated and try and paste them onto the 2nd image in my series, it actualy charges the image as well ! So that the second image becomes the firts image on the keyframes.Is there a way just to copy the opacity and motion animation ONLY ? My guess is there must be because to animate each picture by hand with a custom ease in & out curve would take forvever

I'm sure Adobe is sick of hearing about bugs, but.... one issue that I've noticed with Flash CS4 that was never an issue in CS3 is that when selecting the frames of a complex animation, copying them, and pasting them into another Flash file, often results in some of the artwork getting mixed up.

I am an newbie trying to take an existing Flash game and modifying it for my own selfish goals. I am duplicating symbols and trying to preserve all of their actions so that I can then swap them out for my own symbols. When I swap, actions are preserved, but I have run out of symbols to swap, so now I am trying to duplicate the remaining symbol so I have more to swap with, but when I duplicate the actions are lost. I have adjusted the actions code to accommodate more symbols ( or at least I think I have)
