I am working on the following code and I keep getting a cut off at around the 'C' of Dave's computer.I know this is going to be a simple answer but I for the life of me cannot figure out HOW to extend the string visual field. I am pretty sure the secret lies in the variable len.
Code:
import flash.text.TextField;
import flash.events.Event;
var txtFld:TextField = new TextField();

I am trying to find out what the max length is for a string because since as3 doesnt provide any methods for removing characters from a string by changing the initial string itself, i am going to have to stick to re-initializing.I did a little test to see how long it would take for my program to break using the following code:
Actionscript Code:
+[code]..............
The program crashed at a string length of about 500 million.
EDIT:however before it crashed,it performed the incrementations with reasonable performance.
EDIT EDIT: which is strange since my ram still had over 2 gig the program didnt use
Is there an easy way to get the byte length of a string in AS3? String.length works in many cases, but breaks if it encounters mulibyte unicode characters.(in this particular case, I need to know this so I can preface messages sent across a TCP socket with the message length. This is in standard netstring format e.g. "length:message,").
View 1 RepliesI'm populating a dropDownList with arrayCollection of strings. I want the width of the drop down list control to match with the size (in pixels) of the longest string in the array collection. The problem I'm facing is: the font width of the strings in the collection are different e.g. 'W' looks wider than 'l'. So I estimated the width of a character to be 8 pixels but that's not pretty neat. If a string that has many 'W' and 'M' is encountered the estimation is wrong. So I want precise pixel width of strings. How can i get the exact length of a string in pixels??
My solution that estimates all character to be 8 pixels wide is given below:
public function populateDropDownList():void{
var array:Array = new Array("o","two","three four five six seven eight wwww");
var sampleArrayCollection:ArrayCollection = new ArrayCollection(array);

Is there an actionscript function I can use to pad a string to a certain length with a certain character?
Example: I have a number lets say 274 and I want to make sure that number is at least 6 characters long...with any open space receiving the character 'W'. So I'd call the pad function and my final number would look like this: WWW274
I can obtain the number of characters in a string using the 'length' action script command. However, I need to know the pixel width of this 'length'?
View 1 RepliesI have a string provided to my flash file that I need to break into a max of 3 sentences(strings).
I have written some actionscript to break it up by set lengths, but I also need it to not break words up.
To test you can place the following code in a blank as2 file.
Code:
var personalMessage:String = "You got this far so we reckon that you could be curious enough to learn a little more, we�ll contact you shortly to answer any questions you may have.";
_root.myArray = new Array();
_root.myArray = personalMessage.split("");

I'd like to know a way to measure the real length of a text string in pixels. The problem is that every character has a different width.The length property informs us of how many characters does the string have...but how do we measure the pixels (x space) in a precise way?

var a = new Array()

I am looking at "length" property in the Adobe AS3.0 language ref as I do not understand it. It says: An integer specifying the number of characters in the specified String object. (I understand this). Because all string indexes are zero-based, the index of the last character for any string x is x. length - 1. (I do not understand the "- 1". I understand that all string indexes are zero-based but I cant put this together with the last character for any string being -1 or whatever it is saying.

View 2 RepliesI'm trying to do a test on the length of a string and then call a function depending on the result. This is the pertinent excerpt from the fla file:
Code:
_loc4._comment = candles[_loc3].comment;
// I want to find out the length of _comment and call differently depending
_loc4.onRollOver = function () {
if (_loc4._comment.length > 0 && _loc4._comment.length < 60) {
show_comment(this._comment, this._x + this._parent._x, this._parent._parent._y - 50);
} else {
show_comment(this._comment, this._x + this._parent._x, this._parent._parent._y - 100);
}};
Basically I want to check the length (in characters) of _loc4.comment and if its under 60 call with an offset of 50 and if its not call with an offset of 100.

i made a function for replacing a text letter by letter. You've probably seen this effect of putting in place of a text a random one, with the length of the new text and then replacing the random text, letter by letter with the new one. It worked fine but I had to do some adjustments, because I needed to vertically align the text to the bottom, and I had the newline character in the text which gave me some issues with the aligning. Since I did this adjustments, string.length returns undefined even if trace(string) shows the correct text in the output window. On the other hand length(string) gives me the right answer. I also use the charAt function which also returns undefined, even if the trace function shows the correct text.
View 7 RepliesLet'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 to do this
function foo(x:*, ...args):* {
}
function bar(x:*, ...args):* {[code].....
how to expand args ? when I call bar(1,2,3), I wish it call foo(1,2,3), but it call foo(1,[2,3])

View 3 RepliesI have a MovieClip, "my_mc", that is hidden and shown when you MouseOver a grey block that is on the stage, similar to a tool tip. Inside of this MovieClip is a TextField, "my_textbox", and another MovieClip, "my_box". "my_box" is underneath the textbox and will hold the graphics for the tooltip.
What I am trying to do is add a Sprite to "my_box" and set it's alpha to 50%, or 0.5 AS3. Well, I accomplished doing this, however, when you Mouse Out then Mouse Over again, the alpha increases by 50%, to what seems 75% alpha now, instead of staying at 50%. Do it again and it goes up another 50%, so on and so forth.
I have tried setting the "my_box" alpha, as well as the alpha of the Sprite that is drawn inside, and it still does it. Also another piece of info, when I trace the alpha, I get 0.5, even though it appears to be solid red on screen, after a few MouseOver/MouseOuts.
