I have a project where i'm drawing to a stageSized bitmap by using BitmapData.drawusing the 'show update regions' feature of the debug player, i can see that the player always updates the whole stage although i changed only a small part of the bitmapdata.Can I somehow make the player only update that part of the screen where there were changes made to the bitmap data?
View 2 RepliesIn pure AS3, I have a pixelbender and a large bitmap. The pixelbender is configurable with a distance parameter to affect only a small area of the bitmap. The problem is that the pixelbender is executing over the whole bitmap. What would be the best way to update only the effected region of the bitmap? Given this config:

I've been developing an application which uses a lot of sprites to create a 'wheel of fortune'-like object. Since I use several filters, sprites, countless calculations, and various other tricks to draw it, it became painfully slow to try to spin that, as flash had to redraw everything every frame.
Needless to say, I took the bitmapData 'snapshot' approach - I drew the massive combined sprite to a bitmapData, removed the original sprites, filters, et al from the display list and nulled them, Threw the BMD into a Bitmap object, placed that in a container sprite so that I wouldn't have to continually use a matrix to rotate from the center when it registers at the top left, and started rotating the container.
Unfortunately, it seems that rotating the container with this 500x500 Bitmap in it is nearly as slow as it was when I hadn't snapshotted it and rotated the whole thing, filters and all. I have already played with the BitmapData's transparency, turned on and off cacheAsBitmap on various combinations of containers and the bitmap itself (hahaha), checked the Bitmap.smoothing property out, blah blah blah, the whole nine yards. Rotating a decently sized Bitmap (thus making pre-rendered/calculated frames a really bad idea) ... how do I make this run at a tolerable speed without eating my CPU and turning the fans on?
for the past couple of weeks I've been learning AS3, and for a school project I'm doing a remake of the popular DOS game Liero. Everything is working fine, I got a layer of dirt that I am shooting away, but the problem is that after a few hundred bullets, the game starts to lag heavily whenever a shot is fired.I'm using a simple bitmap and a brush to erase the parts where the bullets hit.
// Drawing stage
bmap = new BitmapData(1100,800, true, 0);
dispBmp = new Bitmap(bmap);

i've created a full spectrum color wheel Sprite object that is composed of 1440 vector triangles, or slices if you will. since i want to animate the color wheel, i've activated the display object's cacheAsBitmap property. however, caching the vector as a bitmap does not increase performance during animation it remains slow, jumpy. importing a PNG screenshot of the color wheel into the library with lossless compression, converting it to a Sprite, and rotating this new image asset performs great during animation. why does an uncompressed PNG image asset import out perform the same vector image with cacheAsBitmap property set to true?

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?
Will I take a big hit in performance using nested ViewStacks? Should I strive to handle all navigation in one ViewStack and push children manually or will the affected performance be negligible?
eg.
<viewstack>
<tabnavigator />
<tabnavigator />
<tabnavigator />
</viewstack>
We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?
View 1 RepliesI am trying to write a flash app that will allow a user to select various regions of an image, similar to that of the selection tool in photoshop where a square region can be stretched and selected.

I have a .png image of all 44 US presidents, I'm trying to figure out how I could break it apart so that each president can be clicked on. I'm a fairly experienced actionscript programmer, have done some game development work in the developer role but never in the design/UI role, thus I'm not great (or even good!) at some of the beginner stuff regarding UI. I was thinking I could use the lasso tool to select an area, then somehow make that selection into a grapic or movie clip symbol, but I can't seem to get that to work and I'm wasting a lot of time experimenting!

View 2 RepliesI've got a small action-script chart, that's meant to be live updating, and also be able to support more than 10000 points of data. The way it's currently set up it doesn't need to redraw the whole chart if the new line we wish to add doesn't extend that chart's boundaries. Yet it does, the redraw regions show the whole chart as being redrawn as opposed to the single line i need to add. When the chart gets a new piece of data from the javascript it does the following.(some stuff has been stripped for clarity.[code] Is there any better way to do that, that won't redraw the whole screen? Is my coding pattern wrong for this type of update?

View 0 RepliesI've been making a flash animation for a client - the dimensions of the stage are 2,000px wide, 800px tall. They want a graphic in the background and a snow effect in the foreground.
The code I have written uses TweenMax to move a snowflake that has been dynamically loaded from the library on to the stage using attachMovie. When the clip leaves the stage, it is deleted and a new clip is created at the top of the stage.
I expect flash to redraw the background that the flakes pass over, but flash seems to also be redrawing space between the flakes - as if they were one movieclip - even though they are separate instances.
I have an array name region it has a couple of properties. "code", "name", "value"
I want to store this array in an indexed object called regions.
I would then like to access the object by referring to its sub property name
regions[1].code
regions[1].name
regions[1].value
I can set an array region.code, region.name and region.value but I can not set the regions values
regions[1].code = "abc"
regions[1].name ="alphabet"
regions[1].value =26
note: region is singular and regions is plural(many)
Can someone outline the variable definition and construct so I can access this information. Happy to replace the index field with the code value.
I am deploying Updates via SCUP and SCCM to hundreds of Computers. Fortunately Adobe provides an SCCM Update Catalog for both Adobe Flash ActiveX and Adobe Flash Plugin. But now my Problem: After publishing the Update via SCCM, the client is not supposed to be interfered with the Update Progress (which is working) I figured the Updater works like this: First SCCM checks if a Update needs to be deployed, if this is the case, The Flash Updater begins. First the old Flash Version is beeing uninstalled. But now: if the Client has a Browser Window (IE, or Firefox) open, the Updater is not able to install the new Flash Version and quits with an Error. This leaves the Client PC without any Flash (because its being uninstalled before) How can I prevent Flash being uninstalled due to the Update progress not working while a Browser window is open?

I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.

I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap;
var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),
If I have a BitmapData that's already been drawn onto a Sprite. Is there a way to redraw the BitmapData onto a Sprites Graphics object without having to invoke beginBitmapFill and passing in the same BitmapData?
View 1 RepliesI'm working on a game, and to keep performance good, instead of addChild'ing 50 new sprites to the stage every second, I decided to have each player draw to their own bitmap, and then to the 'master' bitmap.

I have a bitmap which has several frames (packed along the horizontal axis). In order to render them I copy it to the backbuffer (larger bitmap) as follows:

Is there a way to write a bitmap font right into the bitmap being desplayed? Mabey better worded: myBitmap.draw(image, t) draws a picture is there a way to draw text? I'm stuck even if its just a work around in some way I would like to know... (the current work around i have in my head is writing it in a movieclip turning that into bitmap data and drawing it... esentially creating a prototype answering my question... but a built in way would be easier probably).
