Flash :: Flex Render Culling Objects Not In View To Stop Them Getting Drawn When Not Needed?
Oct 27, 2010
Does anyone have any knowledge (preferably with links to make it official) about how/if Flash/Flex culls objects not in view, to stop them getting drawn when not needed? A specific cases: I have an 800x600 panel (a Canvas or Sprite, or other container) containing loads of Sprites representing individual game objects like asteroids or spaceships or missiles or map-tiles. The game world might be 5000x5000 so can I naively position Sprites anywhere in this range and let Flash cull them effectively? Or do I need to manage visibility somehow at a higher level (like manually removing them from the parent) to avoid performance issues?

Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?

I'm playing with Open Flash Chart. Take a look at this chart: [URL] As you can see, the rounded dot points look ugly. Some of them are more rounded, some of them less, they don't look the same, as they should. I don't know AS3 and have no idea what is the case. I checked the source code:

I'm in the process of making a board game in Flash; as part of process of getting fully to grips with Flash AS3.
I have a JPEG of the original board. This contains ~ 1000 circles that players may move pieces between. Pretty standard board-game stuff. The circles are not in any way regularly spaced.
So far, I've drawn the circles in Flash, by hand, and positioned them where they need to be. This looks great - I can see all my places.
What I want to do now is create these circles programatically. I want to be able to do this so I can adjust how the spaces look (depending on game state). Eventually I'll want to be able to zoom / pan the entire game board as well.
My question is, is there a way of tagging each circle with a unique reference and then looping through and recording locations?
I'm thinking something a bit like the Javascript DOM "getElementsByTagName" or similar.
At the moment I can only see two options:
Convert each circle to a symbol and give it a unique class name so I can access it from code Go through and write down the X/Y of each circle (add to my DB of board locations that I already have) so I can plot them programatically

Using Flash 11 RC1 with the new Molehill API, I would like to enable backface culling. The beta documentation is pretty vague, but the example implies Molehill wants front-facing triangles to wind counter-clockwise, which is pretty normal. But when my polygons wind counter-clockwise, I get the exact opposite behavior - in other words, it's as if contrary to its own examples Molehill expects front-facing triangles to wind clockwise. Since the documentation never explicitly states which winding is correct, I am stumped.
I don't want to just flip all my triangles around until it looks right before I am 100% on what Molehill actually wants, since that has a fair chance of hiding a fundamental misunderstanding. I am using simple perspective projection (a note regarding .transpose() below: because copyRawDataFrom expects data in column-major order, and I hated the way that looked in code, I decided to just enter it row-major and transpose the matrix afterwards

I quickly realized that instantiating all movieclips in the document class all at once is probably not a good idea. I want to call movieclips from the DisplayList, instantiate them when needed. How do I go about on doing that.

In the past, we've put a stop() action in the timeline of movieclip symbols so that the timeline would not play and we would control all animations via code. We've also done that to the main timeline as well. Is this still needed for performance reasons? Is this needed for dynamically created movieclips? I know that the Sprite class should be used if there is no timeline associated with it.

I want to duplicate objects that users have drawn. I set up a pencil class and added those drawings to a container. I tried duplicating the container , which worked, but did not duplicate the drawing. Only the container. I know I'm missing some vital piece of information here.in DOC class:
Code:
public function Seed():void{

I'm currently using RobotLegs with the Presentation Model pattern to develop a Flex 4 project. I understand that all business logic related to a View resides in the Presentation Model associated with that view, however, I am confused when it comes to View specific logic.For example, I have an indicator that needs to be positioned relatively to list items depending on which list item is selected. Is it acceptable in the Presentation pattern to put the logic that will position the indicator in the View and simply have that logic run in reaction to a selectedIndex property changing in the presentation model?The reason I am considering this is that since the Presentation Model does not have a reference to the view it is difficult to come up with an ideal solution for manipulating view components.

If you draw a movieclip (with a 3d rotation on it) to bitmap, eventlisteners will always dispatch rollout and rollover for that movieclip (on mouse over). A solution could be to set the matrix3d = null ,draw, and then apply the original matrix3d, but I can't do this in my project 'cause all clips is a 3d object to a parent 3d object that gets drawn to a bitmap every frame.
To see the bug, copy this example code into the first frame on the stage (CS4 flashplayer 10).
var bmp:BitmapData = new BitmapData(100, 100); //setup a dummy bitmap
var bmpContainer:MovieClip = new MovieClip;
bmpContainer.addChild(new Bitmap(bmp));
var box:MovieClip = new MovieClip;
addChild(box);

[URL]. Our client communicates with a Rails backend to get login details and then logs into an Adobe LCCS server. We have been cruising right along but around noon yesterday we developed a bug that causes the swf to not render until you refresh the page. On subsequent refreshes it pops up right away. The problem happened even when I disabled the code that checks in with the Rails server. How could refreshing make a difference?

I have one .mxml file (the Application) with a ViewStack (with 4 views) and a ControlBard, obviously I can change the views with it, but what I want to do is: in view #1 I have an image which I want to convert to a "hyperlink", so when I click it I go to View #2, is this doable? Also I would like to pass somehow some data (like a String) to that View #2 (lets say the it's a user avatar I click so I want to go to the second view which will show me his profile, that's why I need his name/id).

My problem is that when I try to pass an object from the navigator.pushView(view, dataobject), I can't figure out how to access the dataobject from actionscript. I can access {dataobject.property} from MXML easily, but I want to set a variable in the new view to the passed dataobjects property.

when I move the camera around my scene the rendering at certain points is odd. Triangles become missing and it seems as though its just not working correctly. When you move the camera beside the cube, triangles along the side of the cube go missing. Is there a way I can turn the clipping off? Should I use more triangles? Is it a material/render engine/viewport problem?

I have a project both Flex and WWW and they are very closely connected. I want to put them both into into one SVN. I want to make revisions for changes that take place exactly both in flex and WWW at the same time. My question is that do I have to stick to "subclipse" (it would desynchronise changes for flex and WWW in one revision)? Would be possible to make revisions using only my tortoiseSVN without subclipse?

I have an app where a user puts in the required info into text inputs inside a titlewindow pop up and it sends the data entered into a datagrid. This first time when I call for the popup and enter info it works fine. Here's the problem: the next time I call the component pop up and click anywhere on the popup, including textInputs, the first the item in the array is automatically entered into the textInput where the user is supposed to enter the data themselves (BTW this textInput is also a autocomplete component).What I want is nothing to entered into textinput until the user inputs the data themselves. I've been tweaking with it for hours and im stumped. Here's the code: (this is main page)

We are loading external swf content into an adobe air application. Content is provided by an increasing number of third parties.Being third party content, it will be loaded in a separate security domain (trustContent=false) and a sibling app domain (loadForCompatibility=true). We are doing this using the Loader class.What are the features/options/approaches that would cause problems when using the swf as external content?
I am interested in any kind of issues, as we have already reproduced issues with content that occur regardless of the app domain / security domain where its loaded ( and occurs also in both Loader and SWFLoader).

I'm still learning how to compile with the Flex SDK. And I'm learning how to use SWC files and [EMBED] statements to pull my assets into my application.With the Flash IDE, I can link a library asset to a class and it's automatically embedded into my custom class. So that's 1 asset in 1 class. With the Flex SDK and SWC files, it seems I can only* pull in assets at the variable level, so I end up with my custom classes containing yet another class -- this means I have an extra wrapper/decorator (whatever you want to call it) class that I didn't have when using the Flash IDE.Is this what people typically do? Doesn't that seem superfluous?I've read Colin Moock's 'Essential Actionscript 3.0', where he mentions something about embedding a SWF at class-level as binary data.

Flash Builder's design view is worse than 3's (which at least was usable if you ignore some quirks), so WHAT do Flex UI designers (those who don't have paid design teams...) do to design a complex UI? Because Design View (also based on what a lot of people say about it..) gets more useless with every release.See image for some differences in design view vs.Flash. WHAT is causing this? css also posted..("Duration", "hr", "min" are mx Labels, the image size text is an mx Text comp.Project is an "mx only" SDK 4.1 project.) I don't even care that the spinners look different, I just need it to show me correctly sized stuff so I can position things via Canvas, or properly size containers.

I am evaluating flex for a mobile and a web application and one of things I want to be able to do is show a google docs or a microsoft docs file (doc,ppt) within a flex application. Google docs files are published as web pages so I guess you need a html component with javascript enabled. Does such a component exist in flex 4+? Similarly how would I go about showing a word or a powerpoint file inside a flex app? How does a site like slideshare or scribd do it?

Is it possible to enable verbose build logging in Flash Builder? Ideally, I want to be able to see the exact arguments that are being passed to the mxmlc.exe compiler. Context: I'm currently trying to automate our build process using GradleFx so we can move away from using Flash Builder and run our build on a CI server. At present, I'm running into a few problems and my lack of knowledge about the flash/flex build process is impeding progress. Being able to see what the FB project translates to would greatly aid me in being able to set up the new build scripts.
