Professional :: Working With Large Objects?
Oct 12, 2010
I am preparing a navigation (using panning) movie in Flash. There is very big (6000x4000) image (area photo from top) on the stage and it's position moves once user moves his mouse. Thus, user can navigate on the area.But flash really drives me insane while working on this movie. It usually suddenly stops and quits with error.I'd like to ask what can i do? should i use a different method???It seems, Adobe becomes stupid on large files and there are bugs in somewhere Flash. For example; how can i use a method like Google Maps (it loads an another image when you move another position. Not loads all images together and doesnt consumpt large amount of resources.)?

My company is working on a casual game which is entirely made in Flash. To speed up development/compile time we split some of it up into SWC files, for example dialog controls, cutscenes, particle effects are all controlled via SWC files. This was working great up until a few days ago, we have been working on this project for about 8 months with no major problems. However, now all of a sudden, when we compile the game, none of the SWC files work. The game compiles and runs ok, but nothing from the SWC files are working.
The strange thing is that if we remove one of the SWC files from the folder (the game reads all the SWC files from one folder) then the game will work. Even if you remove a SWC which isnt immediately used by the game it will still work. It's almost as if there is some limit to how many SWC files you can have loaded. (There are only 10 SWC files in the folder we are loading from).

I am trying to create a simple gui component that has a vertical gradient, simple enough right... I create the sprite, and draw the gradient with beginGradientFill and a matrix with a 90 degree radian angle on it; but it stops working if the sprite has a long width, below is an exmaple of what I mean:
package {
import flash.display.GradientType;
import flash.display.Shape;
import flash.display.Sprite;
import flash.geom.Matrix;
[Code] .....
If I change
matrix.createGradientBox(800, 100, Math.PI*0.5, 0, 0);
to
matrix.createGradientBox(800, 100, Math.PI, 0, 0);
It works fine - but horizontally - why is it that applying 90 degrees the fill does not work?

I've been working on an old flash project from a few years back and ran into a little trouble with filters.My program requires the ability to zoom in to any zoom level, which works perfectly fine. And now I've made it so the selected object would glow with the use of Flash's Glow Filter.The problem which has arisen, however is that I get a warning message: "Warning: Filter will not render. The DisplayObject's filtered dimensions (4154, 4154) are too large to be drawn."Now obviously I understand why this would occur, however I'm wondering if there is a way around it. My first guess was setting up a screen size mask, obviously way lower than the max resolution hoping that cull the movie clip to the size of the screen, but that was unsuccessful.
Is there a way to dynamically clip objects and if so would that work? As surely if I could clip the object in run time to the bounds of the screen, the resolution would never exceed that of the screen. If not, any other ideas as to how I can make a large object glow?URL...Also there's dl.dropbox.com/u/956557/Glow/GlowTest.fla if you want to take a gander at the source for that.

Part of a larger presentation I've made, there is some background music. What happens is an XML file is read to get a file to play. It plays. When it finishes, it reads the XML again to get the new file. It can also stop when a video plays elsewhere in the presentation then I pick it up where it left off and start the process again. Trouble is, the presentation randomly stops. The music stops and the slides in the presentation stop. The music and slides come from a single XML file. There's also a third part of the presentation (a text crawler) that never stops.
This comes from a totally separate XML file. I never get an error, the presentation just stops on a slide and no more music plays, but the crawler keeps crawling. I've removed all the code for the music and it runs perfectly so it's obviously related to how the music is managed. So, finally, my question is how do I manage sound objects? If I need to create new objects for each sound I load and play, I'll need to do manage the sound from a single function, right? Something like:
Code:
function whatever():void {
if song is not loaded {
read xml, load and play song;
} else if video is playing {
pause the song;
} else if video has stopped playing {
resume song;
}}

I'm building my first Flex custom component, in Flex 3. It is a data table based on the 'Grid' container class, with a simple text Label in each cell. (DataGrid and AdvancedDataGrid were not appropriate starting points for my needs.) The component works quite well using smallish tables, but I tried stress-testing it using a larger table, and have been disappointed by the results.
The component creation process has some slow spots, but those are in my power to optimize and aren't my primary concern. What worry me more are what appear to be limitations in the Flex framework itself.
This 'large' sample table has a bit over 7000 cells in it. This is largish, but still 1-2 orders of magnitude less than the biggest I need to accommodate. In standard Grid structure, the main portion of the component consists of a Grid with 400 GridRows of 16 GridItems each, plus a few other smaller ancillary Grids.
Once the table renders, I find the following:
Mouse-related events are slow to fire. Specifically, I have rollOver/rollOut event handlers registered on each table cell, to let me highlight the cell under the pointer. On a small table, I could move the mouse over the table very quickly, and the highlighting would follow the pointer in real-time. With the larger table, the highlighting is very jerky, changing only about twice per second, skipping over many cells.If I place the mouse cursor over the component and leave it there, my CPU is pegged (one processor core, anyway), and stays that way until I move off of the component, when it drops to idle. My component isn't doing anything at all at this point.
It feels like Flex simply cannot scale to support component trees that are this large. I shudder to imagine how it would behave with 100,000 cells. Perhaps I'm pushing the Grid beyond its intended use, but having an object per table cell doesn't seem like an unreasonable model, and ~14,000 objects in the tree (a GridItem and a Label per cell) seems pretty modest.

I have a large movieclip that I am adding to the stage (large in dimension, not filesize). Once it is there I plan to manipulate it's X position by clicking different parts of the movieclip. Unfortunately, where I am moving the clip to is based on stage.stageWidth, which changes as soon as you add this movieclip to the stage. So I can't make any accurate tweens or anything like that. Is there a way I can set objects to not affect the screen width when they are loaded? Or still access the property of the actual window's width?

I'm trying to think of the best way to add event listeners(mouse events) to an invisible object which is quite large. A straight forward way I can think of is probably setting the object's alphy property to 0. However since that object is very large, it will probably have a huge impact in performance. Setting invisible to flash however, will stop it listening to events.
e.g. I have a massive area 4000x4000, but I only want the 2000x2000 area to listen to events.
Other methods I can think of is to have the smaller area in the layer below the big area, covering it from view, though I'm not sure if the lower layer can pick up events? another way is maybe just have the big area listen to events, but in the handler I'll write some code to check if its within the boundary of the smaller area.

I am working on a project where I need an interactive matrix of 500x500 clickable lements. I thought this would be an easy task in actionscript3 but boy was I wrong. was able to create a matrix where each element was a Sprite object with attached Mouse click event. But here the performance problems begin. FlashPlayer10 can handle up to 100x100 matrix, but when I increase my matrix I start getting script timeout in browser player... Here is how my "unfinished" matrix looks like.
So how should I approach this problem? I was hoping flash will be able to handle so many elements, but I guess I was wrong. I want to have a pan control to pan around for objects off screen and of course zoom in/out control.It's true I'm not very professional in Flahs and actionscript but a friend who is told me this would be no problem implementing in AS3? I need this in flash as the thing needs to be hosted on website (unless there is a better tool for doing something like this...).

I have to work with arather large XML file (about 25Mo).From that XML file (which I CAN'T touch in any manner), I actually need only a couple attributes in each nodes.Parsing the whole XML to load the data will (of course) lead to a "A script in this move is causing Flash Player to run slowly..."Ideally, I would like to browse the XML, only parsing data needed (like you would do in a database...without having to load the whole database before ;-)But I think this is not possible? Isn't it?So, I was wondering: why shouldn't I treat it like a text file, reading it and taking only the info needed from the file?The problem is that I don't exactly see how to do ;-)Following is a copy paste of the first node only...how would you do to read this text and put in an array:name, cloneof and description?etecting the node name, checking that it exists(i.e 'cloneof" isn't present in each node), and filling the array with the value
Code:
<game name="puckmana" sourcefile="pacman.c" cloneof="puckman" romof="puckman">
<description>PuckMan (Japan set 2)</description>

I'm devloping some library classes for flocking/steering behaviours on large numbers of objects (2000+). I'm finding that at < 500 instances, performance is reasonable. As the numbers increase, framerate bogs down.
I've seen remarkable performance with libraries such as Flint or Box2D with ridiculous #'s of particles / objects, so it should be possible to optimize / refactor my code to be a bit better.
I'm aware of the basic optimizations, such as bitwise operations and optimized for loops. Are there any more fundamental approaches I should be considering? For example, currently each instance is a vector-based MovieClip. Would working with BitmapData be more efficient?

I am trying to create a web site suing adobe Dreamweaver and flash, for the first time.I am trying to upload a webpage that contains swf.When I check mu site I could only see a blank page with the webpage title at the top of the page.When I contacted the webhosting company they say they can see the message that a newer version of adobe flash player is required. From my computer I cannot even see the message.The helpdesk person said there are possibly two reasons for it. Either there is a problem with the code in flash or it is too large.Are they too large to upload? If so, what is the maximum size of file can I upload on a webpage?I know they are basic questions but I am trying to create website on my own.

I found this bug in Flash 8, so I just downloaded CS5.5 trial and I see the same problem. When I increase the image export resolution to get a larger image, at one point the lower section of the image became white (the image has the appropriate size but the content is not rendered in the lower section). As bigger is the image, larger is the white fraction. The amount of useful pixels always stay around 10 or 13 megapixels. Here some examples:Original image was 3375x6710 pixels in the left one and 2625x5219 en the right one.

I have brush off my Flash skills. Usualy I work in FW but now I have to create a banner in various large sizes but with very limited file size so I turn to Flash. My animation needs are very modest: moving ease in/out, rotate back forth and maybe a fade. Have any of you guys have some tips&trix for getting as much (simple) animation with keeping a small file size? Or point me to some tutorials?

I was wondering if anyone here had any advice on rendering large numbers of identicalanimated instances. The first step we undertook was to separate out the parts of the instance which are static and render flag them cache as bitmap. However I was wondering if there was a way of rendering the same object multiple times without the player having to recalculate the animations separately for each etc?

I understand that, in order get an anti-aliased font in a dynamic text field, the most given advice is to embed the font. But that doesn't work for my project since we want to make it available in multiple languages, and there are too many fields that must be embedded, and it greatly increases the file size of just one scene.
The other option I have seen people use is to custom anti-alias, but for some reason, this option just is not working for me. I fiddle and fiddle with the sliders, and no change is ever made. We are only using Arial, so I am at a complete loss as to why I seem to get no changes in the text from this option.
shed light on what might be blocking me from using custom anti-alias in my flash files?

When I copy layers and edit the objects on stage, the objects also change in the other layer(s).
How do I duplicate a layer so that I can modify it with the objects in the old layer being unaffected? There must be a really easy way?

When I click on any of the chairs, the appropriate text loads in the textfields. But when I try a different items like tables. It shows up undefined.
ActionScript Code:
if (images == "chairs" && loadStat == "finished")
{
picLoading("MI_Products/Chairs/chair" + chairInt + ".jpg");
[code]....
I have all the info in 1 txt file seperated appropriately with the &. As I said, all the chairs load up each part of the text file as it should but every other item comes up as undefined in the textbox. I tried giving each loaderTxt a number to differenciate as seperate variables, yet no avail.

I am trying to make a mobile app that inserts information into a database and while I have it pulling information and I have created my services, when I use the standard create service that Flash Builder 4.6 automatically makes, it just does not insert anything at all into the database.
Now, as far as I am concerned, this should then be writing to the database the items of SesID, Lat and Long using the created service token, but when I do this, nothing has entered into the database at all.
