Actionscript 3 :: Any Advantage In Using Vector.<Object> In Place Of A Standard Array?
Jan 17, 2012
Because of the inability to create Vectors dynamically, I'm forced to create one with a very primitive type, i.e. Object: var list:Vector.<Object> = new Vector.<Object>(); I'm assuming that Vector gains its power from being typed as closely as possible, rather than the above, but I may be wrong and there are in-fact still gains when using the above in place of a normal Array or Object:

So I have two circles and a square on stage, myCircle1, myCircle2, and mySquare. You can drag the two circles, if you drop either one outside the square it'll snap back to where it originally was, if it's touching the box it'll snap to the center of the square.
I want it so when the second circle (either one) snaps to the center of the square, the first one will go back to it's original co-ordinates. So only one circle can be in the square at any time.
I've attached my as file with the current code.

1067: Implicit coercion of a value of type __AS3__.vec:Vector.<Foo> to an unrelated type Array.Really? Doesn't Vector include all the properties, methods and signatures of Array? Is there some low level reason Vector cannot be cast to Array?

So I have this waky idea that I would put an array list (or list) or items inside a vector.
For example an array of fruit containing bananas, apples and oranges inside a vector of type fruit.
I could get the array list and thenwalk through it to get what I want.

What is the most efficient way to empty an Array or Vector in ActionScript 3?I've always just re-initialized them:
vector = new Vector.<T>();
array = [];
It doesn't look like there's an empty() function or anything similar.

I've run into a strange Vector out of range error when trying to splice a Vector array. The idea is to cut off the Vector array after a certain point....
var vec:Vector.<int> = new Vector.<int>();
vec.push(1);vec.push(2);vec.push(3);vec.push(4);vec.push(5);
vec.splice(3,vec.length); // output RangeError: Error #1125: The index 5 is out of range 5.
The strange thing is that it works perfectly, if I change the Vector to a regular array like:

I have a quick question for you all. I'm trying to convert over some ActionScript code to C++ and am having a difficult time with this one line:
private var edges:Vector.<Array> What is this exactly? Is this essentially a multidimensional vector then? Or is this simply declaring the vector as a container? I understand from researching that vectors, like C++ vectors, have to be declared with a type. However, in C++ I can't just put down Array, I have to use another vector (probably) so it looks like:
I don't expect you guys to know the C++ equivalent because I'm primarily posting this with AS tags, but if you could confirm my understand of the AS half, that would be great. I did some googling but didn't find any cases where someone used Array as it's type.

I've been working on this for a while, and thought I understood the BitmapData class at least well enough to do basic stuff with it, but I'm doing something wrong.
I'm trying to make a preload function that will load external JPEGs, store them in an Array as BitmapData objects, then distribute them to thumbnail objects after all the images are loaded. The thumbnails are based on an external class I wrote, which already has a function to accept variable data.
My problem is, I can't seem to find a way to store BitmapData objects in an Array. I've even tried using a Vector.<BitmapData> object, but I get the same result, which is no data stored.
Here's the function, isolated from the rest of the script.
[Code]....
The result of this function is supposed to be, a series of images loaded one after the other, stacked 5 pixels down from each other. However, the actual result is, only the last loaded image is displayed. That's true for any number I place in the 'for' loop, only the last loaded image gets displayed.
Obviously I'm doing something wrong with the loading of the 'bitBucket' BitmapData, because it seems to be writing over the previous BitmapData in the Vector series.

First: When creating a Vector, does it have to contain a Flash data type (uint, int, Number) or can I have a Vector of objects I created classes for?
Second :I cannot instantiate a Vector object. All of the documentation I am finding is saying[code]
I get "1084: Syntax Error: expecting identifier before lessthan". I was thinking that maybe I needed to include a library, but the error seems like it knows that I am trying to create a Vector.

If I have declared my vectos object as such ActionScript Code:
private var _delsUI:Vector.<Single> = new Vector.<Single>();
fill it with data like:
ActionScript Code:
_delsUI.push(newListing);
Then later on I decide to use this:
ActionScript Code:
_delsUI = new Vector.<Single>();
Will this essentially destroy all objects and prepare them for GC if there are no other references any where else? or do I have to loop through the entire Vector and delete and set null each object?

I need to copy a 2 dimensional Array or Vector (8x8), the only success i have had so far is using 2x For loops actually assigning the primatives from one Array/Vector to another (works for 1 or 2, but on the scale i need to run this it is unsuitable).
After a bit of digging on the internet i saw that .concat() is the fastest and most code-efficient way to copy, but i can't seem to get it to work?
Here's what i'm doing:
Code:
var _squares:Array = new Array();

I'm developing a small library and trying to outweigh the pros and cons of using Vector vs. Array. So far, I can only think of a few things to think of: Vector only works for FP10, while Array works for both 9 and 10. Vector is typed (which is a wonderful, fabulous thing), but if I'm only using the Array as a private variable, so I have full control over what goes in and comes out of it, this factor may not play as great a part anymore, but definitely great protection.
I believe I heard somewhere that Vector is a lot faster than Array, yet in a quick inconclusive speed test I did a while back, it didn't seem to make any real difference at all. Is Vector really faster than Array? If so, is it faster in all aspects, or only faster in certain situations just as uint is only faster than Number when using byteshifting?

Why is it that I can never change a vector object's color? I mean I would think it'd be as simple as changing the fill color but that does nothing.
And why is it that copying and pasting vector objects from illustrator very inconsistent? Sometimes I get the exact copy, and other times their's three anchor points missing, very much screwing up the look of the object. Also, when I import a vector png image made in photoshop to flash, the fill is hollow at times.

I'm having a very weird problem with a vector in my application.
Details...I have the following classes.
Person,Player,PlayerController.
Player extends Person. Person extends ObjectProxy in order to enable binding.So the Player class has the [Bindable] tag.The PlayerController class contains a remote object calling a php method to receive a firstname and a lastname and when the CallResponder gets the result from the call,the result handler creates a Player instance. At that moment I am trying to push the player object into a Vector..
The problem is the following.Every time the push method is called, the vector is being populated with the last player that was created but not just in the end of the vector. It replaces the other instances as well! So the vector always contains the most recent player instance but in every position of it.I have also tried doing it with an Array and the results are the same.

So far, I have a class that creates a Vector object, and pushes data into it:
ActionScript Code:
public var mList:Vector.<cusClass> = new Vector.<cusClass>();
The data is read by a second class like so:
ActionScript Code:
trace(firstClass.mList);
The problem Im having is take that same Vector and passing it into a third class (from the second class) as an argument in a method: ActionScript Code: views.mUpListing(firstClass.mList);

How would you go about initializing a Vector. with say the values 1, 2, 3, 4, and 5.
Logic would say you could do newVector = new Vector. ( [1, 2, 3, 4, 5] );
You could also try something like this...
var tmp = [1, 2, 3, 4, 5];
newVector = new Vector.();
newVector = newVector.concat(tmp);
But then you get a type error converting Array to Vector.
I'm stumped, am I missing something stupid or does the vector class really not play well with numeric types? You can try making them decimal numbers just to be sure they get cast as number and not int.
