Arrays :: Fastest Way To Merge Multiple Arrays?
Sep 26, 2011
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.

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.

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 been making a game and have run into some problems I want to make a hitTestObject between multiple arrays, i have tried something like this:
for(var i:Number = 0; i < array1.length; i++)
{
array1[i].y -= 10; //Moves object up
for(var a:Number = 0; i < array2.length; a++)
[Code]....
When i run it, some object will detect the collision and will output "hit", but some will ignore that. I have also noticed that some object in the array1 stop running the move code (array1[i].y -= 10) after i have added another array.

I'm trying to load multiple external swf files into my main movie and arrange them on the stage (talking about 20 or more mc-s) So far I figured out how to load one single mc like this:
Code:
// Make request and loader
var request:URLRequest = new URLRequest("pano1.swf");
var loader:Loader = new Loader();

load an array of swf files and add them all to the stage?

I am attempting to search multiple arrays (over 300) for a specific value which will then determine if that question is to be loaded. I have used these over the years as the quizzes simply loaded questions randomly. Now I am appempting to move this into a computer adaptive test format. I have most everything worked out except for this part which is the key to the project.
What I have is 300+ arrays like the ones below. Once a student answers a question either correctly or incorrectly a difcal value is assigned. It is that value I need to search for to determine which question to load.
For example if the student answered a question incorrectly and the difcal was calculated as -4.03 (difcal values are always in array element[0]) I would need to search the all arrays to find that value and then load that array into the question function.
Code:
var q1:Array = new Array();
q1[0] = -4.03;
q1[1] = 0.57;
[code]....

I just have another really quick question about Arrays, this time about Sorting them. I have just re- written my code to work for matching values from 2 arrays and then adding them to the screen.
however it seems as my matching is way off, it matches the items that are at the same index, which is not always the case
The output for the matches, which should be side by sideis as follows (which is incorrect) Therfore i am trying to find values at diffrent index levels

I tried to sort the Array, but it seems as though the array, cannot be sorted the way i want it. I simply wanted to sort it Acending, but changing it to lowecase would not do what i needed it to do.
This is the code, matchInfo function should do all the work
package {
import flash.display.*;

I have two arrays - one for movieclip buttons and one for images. The idea is - rollover a button and it loads it's respective image. I have a loop for the button array that pretty much loads each button and creates a rollover state for it. At the moment it just traces what button the mouse is over. The problem is trying to load the correct image based on that button. The way it is now - it will only load the same image for all the buttons.
Code:
tagPosition = 0;
viciousImgs = new Array("vaI1_mc", "vaI2_mc", "vaI3_mc", "vaI4_mc", "vaI5_mc");
viciousButs = new Array("va1_mc", "va2_mc", "va3_mc", "va4_mc", "va5_mc");
vicious = new Array("vicious_mc", "uTitle_mc", "uTxt_mc", "uButs_mc", viciousImgs, viciousButs);

I'm currently trying to program a flash game using actionscript 3.0 where users would step on insects. Basically, I added multiple instances of insects movieclip and remove them by using hitTest function. When the mouse_mc. hitTestObject(insect), there were times the insect was not removed.
Here are the errors I encountered:
Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display:isplayObjectContainer/swapChildren()
at SteppingGame/hitTest()
Error #1009: Cannot access a property or method of a null object reference.
at insectmc/onEnterFrameEvent_SF()
Also, is there anyway I could simply my code like creating multiple arrays of movieclip insectmc?
Here's my as3 code:
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.ui.Mouse;
import flash.display.Sprite;

- 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.)

So im recreating my ear training program with more effective coding so i can add on to it. original i did.
//88 C8
var mp3Req88:URLRequest = new URLRequest("88.mp3");
var mp3_88:Sound = new Sound();
mp3_88.load(mp3Req88);
I basically got 88 sound files (each note of the piano) doing this code 88 times for each sound. with mathamatical equations made my ear training program.
Is there a simpler way to import these sounds in a loop of some sort so i dont have to do this 88x for the piano and however many times for the other instruments i will be including?
thus var i have tried things along the lines of below with failure
var i:int;
for (i = 0; i < 5; i++)
{
var pianoMP3Req+i:URLRequest=new URLRequest("piano/"i+"mp3");

Code:
function shuffle(wordtestmix,b):Number {
var num : Number = Math.round(Math.random()*2)-1;
return num;

and would still like to randomize the array without splitting the two values up.
What is the best way to declare this type of array and also adjust the randomize code in order to mix it correctly.

I'm working on a game engine with a friend of mine, we plan to make it open source so other people can use it too for their own games. We basically have everything done, but I really want to add multiple ground instance support. I would like to use an Array, to call upon all ground layers on the stage, and put it into one call name for my gravity function. So I wouldn't have to have various strings for each ground instance.
Code:
var groundArray:Array = [ground, ground2, ground3];
var groundtile:MovieClip = groundArray[1];
addChild(groundtile);
This is my gravity..
[Code] .....
What I have so far works perfect without arrays.. When I add my above array, I don't get any errors.. but I fall through the ground.

I've got 6 arrays and need to create a single randomised array pulling the elements out of the original 6 arrays. The extra kicker is that I can't have two elements from a single source array next to each other. I've cobbled this code together:
ActionScript Code:
var a:Array = [["1_1", "1_2", "1_3", "1_4", "1_5", "1_6"],
["2_1", "2_2", "2_3", "2_4", "2_5", "2_6"],
["3_1", "3_2", "3_3", "3_4", "3_5", "3_6"],
["4_1", "4_2", "4_3", "4_4", "4_5", "4_6"],
[Code]....
That works maybe 90% of the time but often on the last 2 or 3 loops it ends up repeating hence the escape clause in the while. I have thought that in the fail situation I could scan through the built array to find a different place to add the value in but was wondering if there is a better overall method out there.

I am creating a computer game with a save game function which outputs the contents of an array to a shared object, so that users don't loose their place.However, I wish for this to work with multiple users, and realise that to do this I need a new seperate "folder" within the shared object being created for each new users data array.I know it must be something like....
// Define the shared object using a "sublevel" for each users data array...
_root.savegame.sublevel = sharedobject.getLocal("savegame"; "/");
// somehow dynamically change "sublevel" to the contents of the var "currentUser" as defined when the user logs in when the game loads up.
OR...
//Define the shared object but using a variable title for the actual SO...
_root.savegame = sharedobject.getLocal("savegame_currentUser", "/");
//with that "currentUser" being dynamically substituted for the contents of the var "currentUser" which is defined when the User logs in when the game loads up.

I have this array that contains the names of various images I want to load into Flash
var imageArray:Array=["image1","image2","image3","image4","image5","image 6","image7","image8","image9","image10"];
Now I want to create 10 different buttons with each button loading in an image. I know there's a way to do this with a for loop without having to make 10 different buttons and writing 10 different functions. Not sure how to correlate the members imageArray with the generated btns.

what I need to do is combine 5 arrays with 5 individual strings (which have come from a JSON webservice) into one single list item in FlashBuilder Burrito. [code]I've pulled these out successfully and each one traces in the debugger, although as I need them all in the same list I'm struggling to establish them as a dataprovider together.If I push the strings and arrays together it is impossible to read properly, as the main Titles are at a different level to any descriptors for the products which are in the arrays.

I am looking for a solution to this issue but I have not yet found anything conclusive. I would love to get some input. What I need to do is basically to take two or more individual PDF-files and merge them into one. Nothing fancy just sticking one after the other and ending up with one file.
I have found AlivePDF and purePDF but those libs both seem to be focused towards generating PDF's from scratch.
