ActionScript 3.0 :: Length Property - All String Indexes Are Zero Based

Sep 30, 2009

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.

Actionscript 3 :: Rotating Images Wit Odd Pixel Sides Length?

Aug 10, 2010

If you have an image whose sides are even for example 48 x 24 you may do this and you are just fine:

matrix.translate(-24, -12);
matrix.rotate(Math.PI);
matrix.translate(24, 12);

But if you have an image of size something like 49 x 25, then there is a problem with those odd pixels, how to compute when and where to add or remove those odd pixels so image gets allways perfectly rotated?

ActionScript 3.0 :: Convert Bitmap Into Sprite Pixel At A Time?

Nov 21, 2010

I'm making a game where the player moves around a map, where the player can walk and where they can't is decided by the color of the pixel they are trying to move onto, which I get using the Bitmap.getPixel method.

What I'd like to do though is when the map image is loaded process it into a sprite or something which I can then use the DisplayObject.hitTest methods on. So I have an array of colors whcih the user can walk on, is there way I could go through each pixel and build something that would let me do that?

Java :: Convert Pixel Location To Latitude/longitude & Vise Versa?

Aug 10, 2011

I need to convert latitude longitude values into pixel positions as well as do the opposite. I've found many solutions to go from lat/lng->pixel, but can't find anything on the reverse.

A couple of notes:

The map is a fixed size, no zooming, no tiles. I don't need anything super accurate, its not important. Preferably mercator projection, but not required. I'm not actually display the result. (Any 2D projection) I can't rely on any web based API's, ie: no Google Maps

A solution in almost any programming language would be fine, as long as it doesn't rely on any platform specific APIs.

This is an example of going from lat/lng->pixel:

var y = Math.round(((-1 * lat) + 90) * (this.MAP_HEIGHT / 180));
var x = Math.round((lng + 180) * (this.MAP_WIDTH / 360));

ActionScript 3.0 :: Flash - Loop Based On Array Length, Splice?

Feb 4, 2011

I 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 :: Max Length Is For A String?

Jun 19, 2011

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.

Actionscript 3 :: Dynamically Create Multiple TextFields Based On Array.length

May 4, 2011

What im looking to do is dynamically create TextFields based on my array.length. So if I have 3 strings in my array then 3 TextFields with the array text needs to be created.

I've managed to actually create TextFields based on the array.length - however afterwards I dont know how to reference them individually, to lets say re-position x, y for array[1]. I've tried saving the Textfields in another array by .push method, but can't seem to reference them correctly.

//Create textfields based on data in Array - in this case 3 textfields
var textArray:Array = new Array('First TextField','TextField Two','Anything, really');
//Array to .push "save" created textfields

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.

Actionscript 3 :: Length Of A String In Pixels?

Jan 7, 2011

I'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);

ActionScript 2.0 :: Split String By Length And Don't Chop Words?

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();

Test Length Of String And Call Function Depending On Result

Sep 29, 2009

I'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.

ActionScript 2.0 :: String.length Stopped Working - Vertically Align The Text To The Bottom

Jan 29, 2010

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.
