Actionscript 3 :: Remove Equally Spaced Elements From An Array With Length Of 'n' To Match A Given Length 'y'?
Mar 9, 2011Let'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.

ActionScript 3.0 :: Unable To Get The Length Of DataGridData?
Feb 23, 2009Here is my main file:
Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="[L=http://www.adobe.com/2006/mxml"]http://www.adobe.com/2006/mxml"[/L] layout="absolute" xmlns:comp="components.*" initialize="xmlData.send()">[code]....
will pass in the dataGridData into the component. But my component (private var dataLength:Number = dataGridData.length) was unable to get the length of dataGridData, and giving "Cannot access a property or method of a null object reference" error message. I debug and realized at the time flex initiate this variable, the data "dataGridData" haven't past in yet. It was past in later.So how do I change my code to let it able to get the length after the dataGridData have past in?

View 1 RepliesActionScript 3.0 :: Flash - Loop Based On Array Length, Splice?
Feb 4, 2011I have an array with many values pushed into it (happen to be names of objects). I am using a for loop to check all of the objects (by index number) for collisions, etc. Periodically, depending on a condition, I want to remove the currently checked object's name from the array list. I noticed that there is a problem if I immediately splice the checked name from the list. Namely, the list gets shorter, which is what I want, but not until I'm done checking all objects. Is it a good idea to solve the issue by incrementing i-- after the splice? I do this so that the object that used to be next in the list doesn't get skipped.It seems to work very well but I want to know if this is a lame/problematic solution and if there are any better ways of dealing with it
for (i=0;i<myarray.length;i++){
var ob=myarray[i]
//any old condition

ActionScript 3.0 :: Remove Values Past An Array Length And Clear Entire Array?
Oct 8, 2009I'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?

ActionScript 3.0 :: For I<array.length Not Doing Whole Array
Aug 7, 2009this 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.

ActionScript 2.0 :: Restricting Length Of An Array
Mar 6, 2006As 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.

ActionScript 3.0 :: Sort Array By Length Of Element?
Mar 20, 2009I have an array which contains strings. I need to sort the array by the length of the string - longest string first.
e.g. if
myArray[0] = "xxx";
myArray[1] = "x";
myArray[2] = "xxxxxxx";
[Code].....
but it didn't work. I guess length is not a property of each array element.
By the way, the array is already large (270,000 elements) - so I need the sort to work very fast, and I don't want to be adding anything else into the array.

View 6 RepliesActionScript 3.0 :: Aggravating Sparse Array For/next Order Vs. Need For .length?
May 21, 2009it would seem (and I guess I read Senocular's thing on this ages ago, but never really believed it)...
Code:
var a:Array = [];
a[0] = "a";
a[1] = "b";[code].....
But make it sparse and it all goes to hell... i.e. if a[0] isn't defined, cases where you're using it as a piece of useful information, there's no guarantee they'll spit out in the same order.On the other hand, if you make it an object, you can't get its length.Does anyone know an elegant way to poll an Array for the number of occupied addresses, and allow it to for/each or for/as in the right order? In PHP it's as easy as count() and foreach(... as $k=>$v). While the latter doesn't do much good for associative arrays, it always works in order on numerical arrays, whether sparse or not...
