Actionscript :: Initialize Array Length In Object After It Has Been Declared?
Feb 24, 2012
I'm using an AS3 class that is:
package {
public class PeopleInfo {
public var elements:int;
[code]....
I'm getting a run-time error: Error #1009: Cannot access a property of method of a null object reference referring to the for loop's first line dataWriteToDB.PeopleName since it is NULL. I'm guessing the problem here is that while dataWriteToDB is declared initially, the array lengths for the arrays in PeopleInfo class have not been set yet. Or, not sure otherwise why it's NULL.

Let's say I have array foo and a positive integer y, where foo.length > y.I want to remove elements from foo so that foo.length becomes y (or very close to it).Also, I need to preserve the first and last element of foo. The indices of the removed elements must be spaced apart as equally as possible. Foo can be sliced, or it can be used to create a new array.
Example: if foo = [a,b,c,d,e,f,g,1,2,3,4,5] and y = 6, then trimmedfoo could be [a,c,e,g,2,4,5] or maybe [a,c,e,2,4,5], but not [a,c,e,g,2,4] because the last element of foo is missing.

How do I initialize a vector with an array of values? I tried this and it complies fine, but does not work!
Code: langs = new Vector.<String>(["en","fr"]);I also need to load an arbitrary array into a vector, like this:
Code:
langlist = ["en","fr"];
langs = new Vector.<String>(langlist);
Is there a way to do this?

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.

"you cannot delete variables that are declared within a function with the var statement".Which, as it happens, is precisely what I was trying to doI want to delete the object because it holds a bunch variables that are no longer needed, to prevent potential speed/memory issues later on.it's impossible (probably with reason) and I know vars are local to a function, so now I'm wondering if it is actually necessary to remove local variables

I'm using the .unshift method therefore the newest values go into [0] and the rest are pushed down.
What is a good method to remove a value from an array once it has passed a certain length? For example i only want my array to hold 5 values.
Also, is there a method for clearing the entire array, ie removing all values? Or will i have to manually change all the values with a loop?

im trying to use array.length to get the total indexs of the array, before running a loop on all of thoes indexs when i attempt to do this(i added a few extra things for the sake of debugging and understanding)
ActionScript Code:
var selectcharacternames:URLVariables = new URLVariables(evt.target.data);
trace(selectcharacternames)[code]....
does array.length not work with url variables is it possible to turn url variables into a array(im assuming it is not a array as a reason why this doesnt work)

I have a simple HTML file which embeds a Flash file. On the page styling I have a #flashContent with width:100% and height:100%; the Flash object itself has width="100%" and height=100% and is inside a div with id="flashContent". The idea is to make the Flash object (which is a game) to fill the whole browser window even as it resizes.
This works with no problems on IE and Firefox, but there is a small problem on Chrome. About 90% of the time when the page first loads all that is shown is black (the page's background color). The game only appears if the user resizes the window; from then on out it works correctly.
I'd like to ask if there is anything I am doing wrong or if there is an workaround to ensure the Flash game appears correctly on the Chrome browser.

I have 2 arrays:
Array 1 = [1,3,5,7,9,10];
Array 2 = [5,7,10];
Now, I wanted to create a new Array the is the same as the length of Array 1. The output should look like this:
New Array = [0,0,5,7,0,10];

I initialize the "point" object like:
point = {x:'209', y:'270'};
trace(point.x);
this is working fine, But I have to initialize the "point" object with a string variable which holds the initialization properties like:
[Code]...
I know this is not working. Is there any method to initialize the object with a string variable which holds the initialization properties (without parsing the text) ?

There doesn't seem to be any documentation on the static method "init()" and the static constant "length" of the Object class. Does anyone have any more insight into these?

this problem is blowing my mind i have a for loop that i want to go through my entire array but it seems to not be counting the last element in the arraay!
Code:
for(var i:int=0; i<gridControl.game.blockG.length; i++){
trace(i +" "+gridControl.game.blockG.length);
}
and the last line of code it spits out is "83 84" meaning that there are 84 items in the array but it only ran through to 83...i dont understand why its doing this.

I've got some coding to create buttons into an array, and on press of these buttons the function should remove something from another array and remove the last one of the line, so far the coding is working for the first removal, however thereafter the other buttons stay there I think it's to do with the line in bold but I cant put my finger on what's wrong with it! The trace's I've set look plausible...
function removeList (event:MouseEvent):void{
myArray.splice(0,1);
list_text.text=myArray.join("");

How would I go about checking the length of a sub array? If I have a code like this:
ActionScript Code:
a = [["a0","a1", "a2", "a3","a4","a5"],
["a0","a1"]];
and I wanted to check the length of the second subarray (the answer would be 2) what would the syntax be?
Edit: the title should obviously be Multidimentional.

As we have in other languages like C, Java that once we define the length of an array we cannot assign any value to the array beyond it's length.[code]This kind of stuff is not possible in C and Java.However AS2.0 calmly accepts the value and increments the length of ii (array) from 3 to 5.Is there any means to restrict the array to accept only particular number of data.
