View 14 RepliesPremesis:I am using actionscript with two arraycollection containing object with value to be matched...Let's assume I have two list of elements A and B (no duplicate values) and I need to compare them and remove all the elements present in both, so at the end I should have
in A all the elements that are in A but not in B
in B all the elements that are in B but not in A
now I do something like that:
for (var i:int = 0 ; i < a.length ;)
{
var isFound:Boolean = false;[code].....
I cycle both the array and if I found a match I remove the items from both of the array (and don't increase the loop value so the for cycle progress in a correct way).I was wondering if (and i'm sure there is) there is a better (and less CPU consuming) way to do it...
flash knows this is a 2d array, correct? Code: var arr:Array= new Array([1,0,6],[4,3,7]); i see it treats it as one. My question, is there any difference to declare each array as such, before pushing them to the main array? trace(arr[0]);// i know it traces the arrays contents, but if it could, would it tell me this is data type Array , exactly the same as if i had declared it?

View 3 RepliesI think i am lost with basics itself. What is the difference between these two. String object is an instance of String Class.
[Code]...
1) Is it true that every data type within as3 is a subtype of Object?
2) Is there any (ANY) difference between typing a variable or function argument or function return as Object versus *?

View 2 RepliesIs there any difference between those three declarations?
var x;
var y:Object;
var z:*;
Is there anything in AS that's not an Object?
What exactly is the difference between an object and a dictionary in Actionscript?
var obj:Object = new Object();
obj.something = "something";
var dict:Dictionary = new Dictionary();
dict.something = "something";
trace(obj.something, dict.something);
The trace statement seems identical...

I'm making an activity that involves measuring the depth of a fictitious river at various points. I have an array containing those depths at the various points and a slider for traversing through the depths and outputting to a textfield.
As the user moves the slider up and down, they can see the depth of the river at that point and plot it onto a graph. What I would like to do is be able to figure out the depths inbetween the explicitly defined values.
here is the code, it's pretty simple:

How would I go about figuring out the values inbetween?
I don't understand what is structurally different between a Value Object and a Class in ActionScript3. Can any Class be a VO if you decide to call it one?
View 1 RepliesWhen declaring a variable to have an open datatype, is there any difference, especially a performance difference, between typing a variable as a "wildcard" (I'm not sure of the official name for this) and typing a variable as an Object?

var quest1:DisplayObject = FrameCanvas.baseCanvas.addChild(app.questionmark1); //
quest1.x = posX; //
quest1.y = posY; //
or
app.questionmark1.x = posX;
app.questionmark1.y = posY;

View 1 RepliesI have a task: I need to place about 100 sprites on one canvas (with prepared grid on it). I need to place them as invisible (circles) stones, on the board, and make visible only on mouseover. The problem I come across is following, I can't place those objects accurately into the nodes on the grid.

I am curious if this is an okay implementation of the Array.filter() method.
[Code]...
I was not able to figure out an implementation of the callback function for the filter() method, where the callback was outside of the getGallery() function. I wonder if there is a way to get the isGallery function outside of the getGallery scope?
I have been trying for an hour to clone an array, It seems that nobody has a true reference on how to do it. Two arrays - movieClipArray 1 and movieClipArray2 I want to duplicate movieClipArray1 entirely so that when I addChild(movieClipArray2[0]), it doesn't take away from movieClipArray1 or reference it in any way.

I am trying to use the following code to convert an object read in from a ByteArray to an Array and store it:
var data:Object = ba.readObject();
var invObjects:Array = data as Array;
In debugging, I find that 'data' is indeed populated with the correct data and takes up memory and is in an Array friendly format. However, invObjects is NULL. How does merely saying 'data as Array' make the holding variable suddenly null?
I created an array in the var declarations with Code: var private eDrag:Array In a function that adds imported mcs to the stage, I also added code to push each to the array. Here is an example of a block of code loading the object with the part pushing the object to the array at the end:

I'm working with a web service and am returning an array to a field (that I set the data type as an Array). The result thus far is "[object Object]". How can I get the array values back out as a string?

[Code].....
What I should do is parse an xml and from its node name create object property and then create an object array based on those property. Am I able to make myself clear.
I'm basically loading an XML file to assign instances of a movie clip a distinct value, which it uses to modify its height. So, I'm looping through the xml and instantiating my class Object each time (Rect) and then placing that Object into an array:
Code:
function loadXML(loaded){
if(loaded){
var boxArray:Array;
xmlNode = this.firstChild;
[code]....
the trace here always comes up undefined. "listPosition" in this bit is an Rect parameter, defined in the previous bit of code as "i", so I can keep track of the order of the stack.I've found one or two examples of putting objects into an array and getting them back out, but it doesn't seem to work with this, maybe because I'm using a class. I don't know.Could this be an area where I need to use the array access brackets, like around the movie clip the object is loaded into. I've tried everything I can think of -- referencing back to the movieclip, adding extra objectRef type parameters... nothing has worked yet.
I have an embedded xml file which I'd like to have a property like this:
<level missions="[m1,m2,m3,m4,m5]"/>
I'd like to know how can I convert the string value [m1,m2,...] into an array, in order to get its value by index (a[0] == "m1", a[1] == "m2", etc.)
I tried Array(xml.levels.level.@missions)[0], but to no avail :)

I have a function that checks if 2 objects are touching OB1 and OB2, if they do touch it runs the rest of the collision code where OB1 is the character and OB2 is a tile that the player cannot pass through.
I came across an issue where i wanted sprites to be separate from the hitboxes but my collision code works by checking the height and width of an object (you guys know the drill).
So i have a Tile class with 2 parts to it, a bitmap and a movieClip.
So i have this setup(pseudocode):
Code:
loop
{
function collision (ob1 , ob2[loop].movieclip)
}
This should work right? But it ONLY works for the first object in the loop!
