• Slick 2d scrolling off screen

  - by Peter

  I have something scrolling in and out of the screen. Now when it goes off screen, I want it to scroll into the screen at another location. What I do is I grab the last pixels at the screens edge using g.copyArea and then g.drawImage on the edge of the screen. And then I do a g.translate to create room for the next row which is next render cycle. My problem is that I get a single pixel row, which is not copied onto the canvas. Where as I want each row to be added and then translated, so that the image that scrolled off screen is recreated on the other side of the screen. Here is my code, maybe there is a better way of doing this, open to any suggests, cause I'm totally stuck @Override public void render(GameContainer gc, Graphics g) throws SlickException { //g.setClip(0, 0, 300, gc.getHeight()); g.translate(0, y); g.drawImage(image,0,200); g.resetTransform(); //g.clearClip(); g.copyArea(rightImage, 0, gc.getHeight() - 1); g.drawImage(rightImage, 300, 0); g.translate(0, y); y=y+3; }

• Graph data structures and journal format for mini-IDE

  - by matec

  Background: I am writing a small/partial IDE. Code is internally converted/parsed into a graph data structure (for fast navigation, syntax-check etc). Functionality to undo/redo (also between sessions) and restoring from crash is implemented by writing to and reading from journal. The journal records modifications to the graph (not to the source). Question: I am hoping for advice on a decision on data-structures and journal format. For the graph I see two possible versions: g-a Graph edges are implemented in the way that one node stores references to other nodes via memory address g-b Every node has an ID. There is an ID-to-memory-address map. Graph uses IDs (instead of addresses) to connect nodes. Moving along an edge from one node to another each time requires lookup in ID-to-address map. And also for the journal: j-a There is a current node (like current working directory in a shell + file-system setting). The journal contains entries like "create new node and connect to current", "connect first child of current node" (relative IDs) j-b Journal uses absolute IDs, e.g. "delete edge 7 - 5", "delete node 5" I could e.g. combine g-a with j-a or combine g-b with j-b. In principle also g-b and j-a should be possible. [My first/original attempt was g-a and a version of j-b that uses addresses, but that turned out to cause severe restrictions: nodes cannot change their addresses (or journal would have to keep track of it), and using journal between two sessions is a mess (or even impossible)] I wonder if variant a or variant b or a combination would be a good idea, what advantages and disadvantages they would have and especially if some variant might be causing troubles later.

• How do you track existing requirements over time?

  - by CaptainAwesomePants

  I'm a software engineer working on a complex, ongoing website. It has a lot of moving parts and a small team of UI designers and business folks adding new features and tweaking old ones. Over the last year or so, we've added hundreds of interesting little edge cases. Planning, implementing, and testing them is not a problem. The problem comes later, when we want to refactor or add another new feature. Nobody remembers half of the old features and edge cases from a year ago. When we want to add a new change, we notice that code does all sorts of things in there, and we're not entirely sure which things are intentional requirements and which are meaningless side effects. Did someone last year request that the login token was supposed to only be valid for 30 minutes, or did some programmers just pick a sensible default? Can we change it? Back when the product was first envisioned, we created some documentation describing how the site worked. Since then we created a few additional documents describing new features, but nobody ever goes back and updates those documents when new features are requested, so the only authoritative documentation is the code itself. But the code provides no justification, no reason for its actions: only the how, never the why. What do other long-running teams do to keep track of what the requirements were and why?

• How does the new google maps make buildings and cityscapes 3D?

  - by Aerovistae

  Anyone who's seen the new Google maps has no doubt taken note of the incredible amount of three-dimensional detail in select American cities such as Boston, New York, Chicago, and San Francisco. They've even modeled the trees, bridges and some of the boats in the harbor! Minor architectural details are present. It's crazy. Looking at it up close, I've found there's a rectangular area around each of those cities, and anything within them is 3Dified, but it cuts off hard and fast at the edge, even if it's in the middle of a building. The edge of the rectangle is where the 3D stops. This leads me to think it's being done algorithmically (which would make sense, given the scale of the project, how many trees and buildings and details there are), and yet I can't imagine how that's possible. How could an algorithm model all these things without extensive data on their shapes and contours? How could it model the individual wires of a bridge, or the statues in a park? It must be done by hand, and yet how could it be for so much detail! Does anyone have any insight on this?

• How to represent a graph with multiple edges allowed between nodes and edges that can selectively disappear

  - by Pops

  I'm trying to figure out what sort of data structure to use for modeling some hypothetical, idealized network usage. In my scenario, a number of users who are hostile to each other are all trying to form networks of computers where all potential connections are known. The computers that one user needs to connect may not be the same as the ones another user needs to connect, though; user 1 might need to connect computers A, B and D while user 2 might need to connect computers B, C and E. Image generated with the help of NCTM Graph Creator I think the core of this is going to be an undirected cyclic graph, with nodes representing computers and edges representing Ethernet cables. However, due to the nature of the scenario, there are a few uncommon features that rule out adjacency lists and adjacency matrices (at least, without non-trivial modifications): edges can become restricted-use; that is, if one user acquires a given network connection, no other user may use that connection in the example, the green user cannot possibly connect to computer A, but the red user has connected B to E despite not having a direct link between them in some cases, a given pair of nodes will be connected by more than one edge in the example, there are two independent cables running from D to E, so the green and blue users were both able to connect those machines directly; however, red can no longer make such a connection if two computers are connected by more than one cable, each user may own no more than one of those cables I'll need to do several operations on this graph, such as: determining whether any particular pair of computers is connected for a given user identifying the optimal path for a given user to connect target computers identifying the highest-latency computer connection for a given user (i.e. longest path without branching) My first thought was to simply create a collection of all of the edges, but that's terrible for searching. The best thing I can think to do now is to modify an adjacency list so that each item in the list contains not only the edge length but also its cost and current owner. Is this a sensible approach? Assuming space is not a concern, would it be reasonable to create multiple copies of the graph (one for each user) rather than a single graph?

• What could cause a sudden stop in Box2D?

  - by alexanderpine

  I'm using Box2d for a game, and I have a bug that's driving me nuts. I've simplified the situation down to a square player sliding back and forth frictionlessly on top of a floor composed of a series of square tiles, driven by the left and right keys (which apply a horizontal force). Works great, sliding back and forth across the whole floor. Except... Every once in a while, the player will suddenly stick at the edge of one of the tiles as if it is hitting a (nonexistent) wall. Further pushes in the same direction it was traveling will fail, but as soon as I push backwards once in the opposite direction, I can push forwards past the sticking point again. The sticking point seems to be random, except for being on the edge of a tile. Happens while going left or right. For debugging purposes, I keep the Positions/velocity values for the previous two update ticks and print them out when this stop occurs. As an example, here you see the player moving right, decelerating slightly; pos2 should be about 8.7, but it stops dead instead. tick0: pos= 8.4636 vel= 7.1875 tick1: pos= 8.5816 vel= 7.0833 tick2: pos= 8.5816 vel= 0.0000 So, as the player is 0.8 and the tiles 1.0 wide, the player is stopping just as it is about to cross onto the next tile (8.5816 + 0.8/2 = 8.9816). In fact, I get a collision message (which I ignore except noting that it happened). It only seems to happen at x.5816 (or -x.4184) while moving right, and x.4167 (or -x.5833) while moving left I said that it's like hitting a wall, but in fact, when it hits a wall, the numbers look more like: tick0: pos0= 12.4131 vel2= 8.4375 tick1: pos1= 12.5555 vel1= 8.5417 tick2: pos2= 12.5850 vel0= 0.0000 so it moves further right on the last tick, which puts it in contact with the wall. Anyone seen anything like this. Any suggestion on how I could be causing this behavior.

• Too many connections to 212.192.255.240

  - by Castor

  Recently, my Internet slowed down drastically. I downloaded a tool to see the TCP/IP connections from my Vista computer. I found out that a lot TCP/IP connections are being connected to 212.192.255.240 through SVCHost. It seems that it is trying to connect to different ports. I think that my computer is being infected with some kind of malware etc. But I am not sure how to get rid of it. I did a little bit of research on this IP but found nothing. Any suggestions are highly appreciated. UPDATE: This is the HiJackThis log file and I can't find any thing weird. Also, the program is also trying to create connections to 91.205.127.63, which is also from Russia.

• : in node causing Keyerror in xmlparsing using ElementTree

  Hi I'm using ElementTree to parse out an xml feed from Kuler. I'm only beginning in python but am stuck here. The parsing works fine until I attempt to retrieve any nodes containing ':' e.g kuler:swatchHexColor Below is a cut down version of the full feed but same structure: <rss xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:kuler="http://kuler.adobe.com/kuler/API/rss/" xmlns:rss="http://blogs.law.harvard.edu/tech/rss" version="2.0"> <channel> <title>kuler popular themes</title> <item> <title>Theme Title: Fresh Money</title> <description> &lt;img src="http://kuler-api.adobe.com/kuler/themeImages/theme_808366.png" /&gt;&lt;br /&gt; Artist: thesylph005&lt;br /&gt; ThemeID: 808366&lt;br /&gt; Posted: 03/02/2010&lt;br /&gt; Hex: 2F400D, 8CBF26, A8CA65, E8E5B0, 419184 </description> <kuler:themeItem> <kuler:themeID>808366</kuler:themeID> <kuler:themeTitle>Fresh Money</kuler:themeTitle> <kuler:themeImage>http://kuler-api.adobe.com/kuler/themeImages/theme_808366.png</kuler:themeImage> <kuler:themeAuthor> <kuler:authorID>370750</kuler:authorID> <kuler:authorLabel>thesylph005</kuler:authorLabel> </kuler:themeAuthor> <kuler:themeTags/> <kuler:themeRating>4</kuler:themeRating> <kuler:themeDownloadCount>708</kuler:themeDownloadCount> <kuler:themeCreatedAt>20100302</kuler:themeCreatedAt> <kuler:themeEditedAt>20100302</kuler:themeEditedAt> <kuler:themeSwatches> <kuler:swatch> <kuler:swatchHexColor>2F400D</kuler:swatchHexColor> <kuler:swatchColorMode>rgb</kuler:swatchColorMode> <kuler:swatchChannel1>0.183333</kuler:swatchChannel1> <kuler:swatchChannel2>0.25</kuler:swatchChannel2> <kuler:swatchChannel3>0.05</kuler:swatchChannel3> <kuler:swatchChannel4>0.0</kuler:swatchChannel4> <kuler:swatchIndex>0</kuler:swatchIndex> </kuler:swatch> <kuler:swatch> <kuler:swatchHexColor>8CBF26</kuler:swatchHexColor> <kuler:swatchColorMode>rgb</kuler:swatchColorMode> <kuler:swatchChannel1>0.55</kuler:swatchChannel1> <kuler:swatchChannel2>0.75</kuler:swatchChannel2> <kuler:swatchChannel3>0.15</kuler:swatchChannel3> <kuler:swatchChannel4>0.0</kuler:swatchChannel4> <kuler:swatchIndex>1</kuler:swatchIndex> </kuler:swatch> <kuler:swatch> <kuler:swatchHexColor>A8CA65</kuler:swatchHexColor> <kuler:swatchColorMode>rgb</kuler:swatchColorMode> <kuler:swatchChannel1>0.659722</kuler:swatchChannel1> <kuler:swatchChannel2>0.791667</kuler:swatchChannel2> <kuler:swatchChannel3>0.395833</kuler:swatchChannel3> <kuler:swatchChannel4>0.0</kuler:swatchChannel4> <kuler:swatchIndex>2</kuler:swatchIndex> </kuler:swatch> <kuler:swatch> <kuler:swatchHexColor>E8E5B0</kuler:swatchHexColor> <kuler:swatchColorMode>rgb</kuler:swatchColorMode> <kuler:swatchChannel1>0.91</kuler:swatchChannel1> <kuler:swatchChannel2>0.898047</kuler:swatchChannel2> <kuler:swatchChannel3>0.688705</kuler:swatchChannel3> <kuler:swatchChannel4>0.0</kuler:swatchChannel4> <kuler:swatchIndex>3</kuler:swatchIndex> </kuler:swatch> <kuler:swatch> <kuler:swatchHexColor>419184</kuler:swatchHexColor> <kuler:swatchColorMode>rgb</kuler:swatchColorMode> <kuler:swatchChannel1>0.254901</kuler:swatchChannel1> <kuler:swatchChannel2>0.57</kuler:swatchChannel2> <kuler:swatchChannel3>0.519034</kuler:swatchChannel3> <kuler:swatchChannel4>0.0</kuler:swatchChannel4> <kuler:swatchIndex>4</kuler:swatchIndex> </kuler:swatch> </kuler:themeSwatches> Tue, 30 Mar 2010 11:27:12 PST So if I do a findall on say each item's description, I get that back fine.

• Get "term is undefined” error when trying to assign arrayList to List component dataSource

  - by user1814467

  I'm creating an online game where people log in and then have the list of current players displayed. When the user enters a "room" it dispatches an SFSEvent which includes a Room object with the list of users as User objects in that room. As that event's callback function, I get the list of current users which is an Array, switch the View Stack child index, and then I wrap the user list array in an ArrayList before I assign it to the MXML Spark List component's dataSource. Here's my code: My Actionscript Code Section (PreGame.as): private function onRoomJoin(event:SFSEvent):void { const room:Room = this._sfs.getRoomByName(PREGAME_ROOM); this.selectedChild = waitingRoom; /** I know I should be using event listeners * but this is a temporary fix, otherwise * I keep getting null object errors * do to the li_users list not being * created in time for the dataProvider assignment **/ setTimeout(function ():void { const userList:ArrayList = new ArrayList(room.userList); this.li_users.dataProvider = userList; // This is where the error gets thrown },1000); } My MXML Code: <?xml version="1.0" encoding="utf-8"?> <mx:ViewStack xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="preGame_initializeHandler(event)" > <fx:Script source="PreGame.as"/> <s:NavigatorContent id="nc_loginScreen"> /** Login Screen Code **/ </s:NavigatorContent> /** Start of Waiting Room code **/ <s:NavigatorContent id="waitingRoom"> <s:Panel id="pn_users" width="400" height="400" title="Users"> /** This is the List in question **/ <s:List id="li_users" width="100%" height="100%"/> </s:Panel> </s:NavigatorContent> </mx:ViewStack> However, I keep getting this error: TypeError: Error #1010: A term is undefined and has no properties Any ideas what I'm doing wrong? The arrayList has data, so I know it's not empty/null.

Why is this the case?

With some tests I found out that the internal swf is loaded correctly, because it's later added applicationComplete-Function is called. Is this a bug in Adobe-Flash-Player or am I missunderstanding something ? Update: Internet Explorer is fine. Firefox and Chrome not...

• What does the JS function 'postMessage()' do when called on an html object tag?

  - by Stephano

  I was recently searching for a way to call the print function on a PDF I was displaying in adobe air. I solved this problem with a little help from this fellow, and by calling postMessage on my PDF like so: //this is the HTML I use to view my PDF <object id="PDFObj" data="test.pdf" type="application/pdf"/> ... //this actionscript lives in my air app var pdfObj:Object = htmlLoader.window.document.getElementById("PDFObj"); pdfObj.postMessage([message]); I've tried this in JavaScript as well, just to be sure it wasn't adobe sneaking in and helping me out... var obj = document.getElementById("PDFObj"); obj.postMessage([message]); Works well in JavaScript and in ActionScript. I looked up what the MDC had to say about postMessage, but all I found was window.postMessage. Now, the code works like a charm, and postMessage magically sends my message to my PDF's embedded JavaScript. However, I'm still not sure how I'm doing this. I found adobe talking about this method, but not really explaining it: HTML-PDF communication basics JavaScript in an HTML page can send a message to JavaScript in PDF content by calling the postMessage() method of the DOM object representing the PDF content. Any ideas how this is accomplished?

• SparkDataContainer Scroller not scrolling to bottom of container

  - by AZSL

  I am using a scroller component within a custom skin for a SkinnableDataContainer. I am running into an issue in that the thumbbar of the scroller stops at about the 50% point, however this is actually the end of the scrollable area. In actuality, the thumbbar should be at the bottom of the scroll track. Here's the code for the scroller: <s:SparkSkin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/halo" bottom="150" > <!-- Properties of the parent ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --> <s:states> <s:State name="normal" /> <s:State name="disabled" /> </s:states> <!-- Metadata ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --> <fx:Metadata> [HostComponent("spark.components.SkinnableDataContainer")] </fx:Metadata> <!-- UI components ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --> <s:Rect left="0" right="0" bottom="0" top="0" radiusX="4" radiusY="4" > <s:fill> <s:SolidColor id="fillColor" color="0xEFEFEF"/> </s:fill> </s:Rect> <s:Group width="905" height="395" id="mainGroup"> <s:Scroller left="10" right="10" top="4" bottom="10" > <s:DataGroup id="dataGroup" /> </s:Scroller> <s:Rect left="0" right="0" top="0" bottom="0"> <s:stroke> <s:SolidColorStroke weight="1" color="0xD8D8D8"/> </s:stroke> </s:Rect> </s:Group>

• pdfmark for docinfo metadata in pdf is not accepting accented characters in Keywords or Subject

  - by rpilkey

  I am inserting metadata into postscript files with a program, to be distilled to pdf with Adobe Distiller. I am using this code that I grabbed from Thomas Merz's "Web Publishing with Acrobat-PDF": /pdfmark where {pop} {userdict /pdfmark /cleartomark load put} ifelse [ /Title (mot accenté) /Author (mot accenté) /Subject (mot accenté) /Keywords (mot accenté) /DOCINFO pdfmark When you look at the metadata, the accented characters turn into "?" in the Subject and Keyword fields, but not the Title and Author fields. The characters are the same ascii 233 I tried replacing them with octal encoding (\351), which came out the same (Title and Author okay, Subject and Keywords messed up). file encoding is latin-1,unix eol I found a mention on adobe forums, but the answer didn't make sense to me. http://forums.adobe.com/message/1165593 I changed the encoding to utf-8, inserted the characters binarily (in VIM : <Ctrl-v>u00e9), no change. I tried inserting the BOM in a few places, it didn't work. This is with Acrobat Pro 9 I didn't notice this problem with Acrobat Pro 7. Does anybody know of a workaround to get the accented characters into ALL the metadata fields when modifying a postscript file, or tell me if I'm doing it wrong? It seems weird that different fields would not accept the same bytes.

• Flex: How to access movieclips within an imported swf

  - by squared

  Hello, I have imported a swf (not created with Flex, i.e. non-framework) into a Flex application. Once loaded, I would like to access movieclips within that imported swf. Looking at Adobe's docs (http://livedocs.adobe.com/flex/3/html/help.html?content=controls_15.html), it seems straightforward; however, their examples are between a Flex app and an imported swf (created with Flex). Like their example, I'm trying to use the SystemManager to access the imported swf's content; however, I receive the following error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@58ca241 to mx.managers.SystemManager. Is this error occurring because I'm importing a non-framework swf into a framework swf? Thanks in advance for any assistance. Code: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:SWFLoader source="assets/test.swf" id="loader" creationComplete="swfLoaded()" /> <mx:Script> <![CDATA[ import mx.managers.SystemManager; [Bindable] public var loadedSM:SystemManager; private function swfLoaded():void { loadedSM = SystemManager(loader.content); } ]]> </mx:Script> </mx:Application>

• Flex 4 - Highlight keywords in a block of text using TextLine

  - by Baz

  I have a search and results page that I would like to highlight the keywords that were searched for, in the text of the results. It was suggested that I use TextLine for this, but I am having trouble figuring out how to make it work. I started a simple, compilable dummy application and was hoping someone could give me some tips on how to continue: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="initApp();"> <fx:Script> import flash.display.Sprite; import flash.text.engine.*; private var textLine:TextLine; private function initApp():void { var normalFormat:ElementFormat = new ElementFormat(null, 12, 0x000000); var highlightFormat:ElementFormat = new ElementFormat(null, 14, 0xff0000); var textBlock:TextBlock = new TextBlock(new TextElement("This is text that has KEYWORDS. I would like to highlight these KEYWORDS by changing their font color and adding a light yellow background graphic.", normalFormat)); textLine = textBlock.createTextLine(); textLine.y = 100; embeddedFontHolder.addChild(textLine); } </fx:Script> <mx:UIComponent width="100%" id="embeddedFontHolder" /> </s:Application> Anyone have any ideas? Cheers, Baz

• Flex: Linebreak problem with spark.components.TextArea inside a MXDataGridItemRenderer

  - by radgar

  Hi, I have a DataGrid that has a MXDataGridItemRenderer applied as an itemEditor to one of the columns. The editor includes a spark.components.TextArea control. By default, any text item editor of a datagrid closes itself when [enter] key is pressed.. Keeping this in mind; What I want to do is: Prevent editor from closing on [SHIFT+ENTER] key but accept the linebreak (I can do this, see code below) Close the editor on [ENTER] key but do not accept the linebreak (could not achieve this) Here is the current code in the MXDataGridItemRenderer: <s:MXDataGridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" focusEnabled="true" > <fx:Script> <![CDATA[ protected function onTxtDataKeyDown(event:KeyboardEvent):void { //Prevent editor from closing on [SHIFT+ENTER] key but accept the linebreak // » this works if (event.shiftKey && event.keyCode == 13) { event.stopImmediatePropagation(); } //Close the editor on [ENTER] key but do not accept the linebreak else if (event.keyCode == 13) { event.preventDefault(); } // » does not work } ]]> </fx:Script> <s:TextArea id="txtData" paddingTop="3" lineBreak="explicit" text="{dataGridListData.label}" verticalScrollPolicy="auto" horizontalScrollPolicy="off" keyDown="onTxtDataKeyDown(event)" /> I also tried the textInput event but that did not do the trick. So: How can I prevent the linebreak when the editor is closed on [enter] key? Any help is appreciated. Thanks. EDIT: If I change the spark.components.TextArea to mx.controls.TextArea, second part with event.preventDefault() will work as expected but then the first part where SHIFT+ENTER accepts the linebreak will not work.
