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.
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.
I am trying to get the length of arrays within an array, here is my example (MX 2004):
[Code]...
I get an output of of 3. the number of variables within the first array, this is not what I had expedted.
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 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];
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'm having a problem checking the position of elements in an array.. for example if I have an array as follows :-I have drawn the number 68 (I always exclude the number drawn). I am checking this array of numbers to see if any exist in the same 'row'Say I have already drawn 61,62 and 63. I don't want this to 'return as true' when I check the array because yes the numbers exist but there is a gap (the numbers arSo I would like to accept if I had 68, 69, 70 because they are sequential from 68 but if I also have 72 I don't wish to accept that number.
View 19 RepliesIs there a way of checking all the strings in an Array in one time ex:
Code: Select allvar array:Array = new Array("string1","string2","...")
if(text_field.text == array[everything]){
doSomething()
}
I already tried "for(var i:Number = 0; i<=array.length; i++){ ..." it just doesn't work well enough enough.
I need a way to read the length of my array, automatically create that many frames in the main.fla and read each screen from my array and display it accordingly on each frame. How to do this?
E.g.. In A.xml, I calculated 10 screens, so Ii need to create 10 frames for A.xml....and in my B.xml, I have 25 screens, there Iit should create 25 frames.
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("");

I like to use array.length in my for loop to keep my code cleaner to read. Is there any huge downside to this? For example will it speed up things greatly if i store the length in a var one time?

How can I find out the length of the second dimension in a multidimensional array?
this is not working:
Code:
trace(my_array[i].length);
(i being a number incremented by a for-loop (starting at 0 of course))
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.

I am doing a flash game with Actionscript 2.0 and have encountered a problem. I have this statement _root.bulletArray = [] that is storing all my movieclips that have been created with attachMovieClip. I was able to store all bullets in the array because when I say for it to trace the array I get the following:
[Code]...
I'm trying to do something such as:
Code:
var n:Node = openList.shift();
I know that all of the data contained inside openList is a type of Node object, but Flash returns an error. I don't know how to typecast such as placing (in another language)...
Code:
(Node) openList.shift();
...to tell Flash that the data returned will be a Node object.
Better yet, is there a way to specify, while declaring the array, the type of the data that will be placed in it?
I could just take the :Node tag out from my variable declaration, but this might be in a tutorial, so I should at least act like I believe half the stuff about proper coding I write about
I have a string, and I have to check if this value exists in an array, but it inside an IFI dunno if I explained well..

I 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.
I have a question i need to get the length of an array but outside the onLoad()

How do you find the length of an Associative Array? The standard "arrayName.length" returns 0.
View 2 RepliesHow do I set the width of the array and length and set each of the values in it to the same number. This is for a game I am working on. I know you use for loops to find the x and y of the values... This doesn't work, but think its how it suppose to work.
Code:
_global.ymap = 4;
_global.xmap = 4;
for (y=0; y<_global.ymap; y++) {
for (x=0; x<_global.xmap; x++) {
_global.map[y][x] = 1;
}} trace(_global.map[4][4]);
I am attaching mc's from the library using xml to populate the textfields. What I am wanting to do is show the first six mc's, then after say 10 seconds show the next six. With a text field displaying "1 of 3", after 10 seconds, "2 of 3" ....etc. A bit similar to image galleries really (sorry if I haven't explained this very well).Anyhoo, heres what I have so far, it loads the mc's one after each other:
