ActionScript 3.0 :: ASCII And Unicode NULL "0x00" Completely Cuts Off End Of String
Apr 1, 2010
I have run into this before, and just ran into it again, and was completely confused how a bytearray converted to a string was only 4 characters long. The problem is, if you EVER try to append a NULL character (not the ActionScript null, but the string value of the char 0), it cuts off the end of the string when printing out in trace or displaying onstage. HOWEVER, if you trace out the length of the string, you get the full length, so the problem arises trying to print the contents onto trace or the stage.
use unicode character 187 (hex:BB) or ascii character 174 as a seperation character in my mysql database.This was working great in one of my swf files but not flash keeps reading an extra character. [code]The trace output from this looks like this: 1«1.If I change the php so that it's sending a 1B1 (no special characters) it works ok.I tried using the ASCII version and the Unicode version alt-174 and alt-0187 and both return this extra %2c character.I have tried urlencode from php, but even sending a 1%BB1 provides the same results.I can't fathom why it would all of a sudden start adding extra characters. So should I change my seperation character. If so, what's recommend? If not, should I check every variables from php for this extra character and remove it?
How can I check if a string has any other character than the ones listed here: [URL]
I would like to know if the string was inputted in any other language than English. Is finding special characters in the string the best way to detect non-english characters?
In Sweden we have these characters (and of course also in caps). But my MySQL db can't store characters, so if I look in the db and search for my name, Bostm, i can't find it..The search is ran from within flash (mx2004, and from there to a php-script, wich then sends the matching row back to flash.I want to convert all thein a string, and to be able to reconvert them when flash gets the string back... So the string should be stored in the db with the encoded...(am I confusing you now?)And I can't use the html-code for 'cause if the php-script prints this: Wow... quite an explanation...Ok, short summary:
AS-sting: Bostrm >encode (so that =ASCII or so) >send to PHP-script
var bytes:ByteArray = new ByteArray; bytes.writeInt(0);
trace(bytes.length); // prints 4 trace(bytes.toString().length); // prints 4
When I run the above code the output suggests that every character in the string returned by toString contains one byte from the ByteArray. This is of course great if you want to display the content of the ByteArray, but not so great if you want to send its content encoded in a string and the size of the string matters.Is it possible to get a string from the ByteArray where every character in the string contains two bytes from the ByteArray?
In document class action script file I add a movie clip to stage using
Code: public var square:Square square = new Square addChild(square)
So it adds square to stage.Then after sometime I want it to be removed. I call a function "removeSquare" also located in document class. It executes the following code. And it removes the square from stage visualy.
Code: trace("proff that it's executed") removeChild(square) square = null
Then of course I want to add a square to stage again, using code I written at top of the post. And remove it again, and so on..But game is lagging more and more and more. So I guess that the square is not properly removed. If you need more details about my code feel free to say, I just written that since I really doesn't know what else should be important.
I have a news scroller which is working apart from one thing: The end of the text string does not quite scroll completely off the screen - it disappears into thin air near the end and THEN starts scrolling from right to left again. How do I make it so the text scrolls completely off the screen before returning?
I'd like the words in the string to type out in the allotted time, but for some reason my function appends the first and last letter of anything in the string, so "Hello?" becomes "ello." This is not affected if I pad the text in the string with spaces, i.e. " Hello? " Nor does this work if I start count i at -1, not 0.
import flash.utils.Timer;import flash.events.TimerEvent; var str:String = "Hello?"; var i:int = -1;var delay:int = 720%str.length; var timer:Timer = new Timer(delay); timer.start(); timer.addEventListener(TimerEvent.TIMER,gotime); function gotime(e:TimerEvent){ textbox_txt.appendText(str.charAt(i));i++; if (i>=str.length){timer.stop();}}
I am trying to convert a bytearray into a string. The problem is whenever I try to append a NULL character using String.fromCharCode(0) it cuts off the end of the string and than I cant run it throw base64. I tried using String.fromCharCode(32) (space) instead but no luck.
I have to parse out color information from HTML data. The colors can either be RGB colors or file names to a swatch image. I used [URL] to develop and test the patterns. I copied the AS regular expression code verbatim from the tool into Flex Builder. But, when I exec the pattern against the string I get a null. Here are the patterns and an example of the string (I took the correct HTML tags out so the strings would show correctly):
I'm trying to create a website for my wife. Everything is completed and it looks great. The only problem I'm having is that when my wife goes to view the websit on her computer (much smaller size). The page cuts off and there's no scroll bar feature which I thought was like a fixture on websites. I've been looking for hours on how to add a scroll bar to my entire website .. like the standard browser scroll bar but I can't seem to find it anywhere.
I have two files, one is the index.fla file which i used to create my page in using Flash CS5 and the other is the index.html file which I can edit in Dreamweaver.
I'm having this annoying proble with BitmapData. I try to turn a movieclip into a bitmap, but there is always white space to the right and bottom. At the top and left, it is obvious that part of the movieclip was cut off. However, the width and height of the bitmap are correct. In other words, white space takes up where the rest of my movieclip should go. About 30% of the bitmap is white.I have a method that creates a grid based on an array. The Wall class extends MovieClip. Each wall is a 70 x 70 movie clip that looks like a stone (its x and y are established within the class itself).[code]I have messed around with changing the registration using a class I found online, but it didn't fix anything. In fact, changing the registration made no difference. Also, I have called addChild(walls), and everything is displayed correctly. But for performance reasons, I need to make it a bitmap.
I just purchased and installed FMS for my music streaming service. I got the streaming set up fine so that it streams mp3s using the VOD application, but quite regularly the stream will just cut out and the VOD application in the administration section will just disappear and restart with 0 clients. It doesn't even happen when I have that many connected clients, at times it's happened with just 15 users, and i've had Red5 running over 200 clients at a time.
I'm writing a flex app, which must record an audio and then playback. It records just fine, I can hear the flv on the server, but when it comes to the playback it cuts the end a little bit, and each time I ask to reproduce again it cuts a little bit more. I guess it's something related to buffer management, but I don't know exactly.
Here's the code I'm using to playback. It is called from a mediator: var streamPlayClient:Object = new Object(); this.stream.client = streamPlayClient; streamPlayClient.onPlayStatus = function(infoObject:Object):void { if (infoObject.code == "NetStream.Buffer.Flush") { stopPlayback(); }} this.stream.play("flv:" + this.streamName);
I have a problem with the TabNavigator. The labels of the tabs are getting truncated and once the user places their mouse over the tab it redraws again. Is there anyway to redraw the label of the tab programmatically?
The zoom just works fine by changing the value from 1 up to 3 with a slider. Midpoint of the zoom is the center of the container (map).My problem: when i zoom, the scroller cuts a part of the groups. it zooms out of the window?!
I rotating some bitmap data in AS3. When ever I start rotating the bitmap the corners get cut off. I'm trying figure out what size the bitmap should be to fit the newly rotated bitmap.
I've attached some images for reference, but as I make my window larger the bottom of my stage gets cut off. I'm working off of a website template and am not particularly sure how the elastic function works. I've had some success changing the code to
Code: Stage.align = "T"; and Stage.scaleMode = "showAll";
but then there are just solid blocks on either side of the background image that don't look very good.
so the bottom will be locked in place and not get cut off when resizing the window.
I have a movieclip on my main timeline. Inside of the movie clip are a few goodies which load in a sound clip. I'm using this code to play the sound:
Code: // create sound object loop = new Sound(this); loop.attachSound("muzak");
[Code]....
This works great, until the main timeline is navigated backwards. For example I have web pages on frames 146,147,148, 149, etc... The menu links go to anyone of the given frames/pages. If I navigate so that the timeline is advancing, the muzak keeps playing. However, if I'm on frame 150 and use a menu button which takes us back to 147 (or anything before 150 on the timeline), the sound quits.
I'm displaying a 720x1280 image in a 720x1280 SWF. My screen is 1366x768.The visualization is awful since my image is cut off (although internally the image's size is still 720x1280 when I do trace() ).Everything is suitably displayed on Firefox.
I am taking feed files from an XML, so in order to make those not throw out errors when reading the XML, I convert all entities to their numerical equivalents and write them as "�" for example.This then gets imported into a database, so that it now has "�" in the database.
I then take the text in the database and use that to generate a new XML file, which still contains the "".Flash then reads this XML file and displays the text.Now I think every character is fine (haven't seen all of them, but seen many), including "" (), however, for some reason, the ï symbol refuses to work () and it just displays and not the symbol.
This is really simple, but I can't it after spending 20+ minutes searching on google! I just want a function that turns a number into a character; basically the inverse of mystring.charCodeAt(0). For example-
I am working on a Flex project that is interfacing with physical hardware.Using the AS3 command of socket.send I can set a particular feature on the physical hardware.The problem I am having is I need access to send from the Extended ASCII codes.[code]This would be translated to me sending two numbers to the hardware.7F and 07. The Dec equivalent of these Hex codes are 127 and 7.The hardware takes these two numbers and calculates a length along with a third integer.[code]
Unfortunately the Hex 88 is in the extended ASCII table.The highest the regular goes up to is 7f which is a Dex of 127.I need the ability to send full 0 to 255 numbers in ASCII form.I can't send from 128-255 without using the codes from the ASCII extended table.I get an error every time I try to send something form the extended ASCII table back from the hardware.Can anyone confirm that AS3 does not support the Extended ASCII codes?
I'm running some script using the charAt() function, that is supposed to return the character at specific indexes in a string, however for some reason it is returning ASCII values.
I want to create a board class from canvas, which will allow to track click position on it in coordinates like A2, where A...D is Y coordinate in some scale and 1...3 is X coordinate [URL]What I want to create is a kind of convertor from canvas localX and localY to my new coordinates like A2.I am thinking of implementing if condition this way if (0.4 - x*size(from 1-3 here)/canvas.width <= X <= 0.4 + x*size(from 1-3 here)/canvas.width) X = x;
This way I can assigned needed coordinates in X range. e.g. 1, 2 ,3 etc But what to do with alphanumeric range. (if for example I want to make it extensible)...
I'm trying to allow ascii codes to be entered into a textField, using num codes (ALT+Num), and am seeing some very strange behaviour. If I enter: Alt + 14, I get a charCode of 9835, and ♫ is displayed in my trace output, but a placeholder square is entered in the textField. If I enter: Alt + 0014, I get a charCode of 14, placeholder square is displayed in trace, and ♫ is displayed properly in the text field.
