I'm making a mobile game with lots of objects scrolling down the screen and I seem to have a weird performance issue which I'm not sure why it occurs. These objects are all bitmap objects and it works completely fine with 40/40 fps when there isn't a background behind. But once I added a background behind my framerate starts to drop and ranges from 30-40. Anyone has any idea why that's happening?

this is what i'm trying to accomplish; With a click on a movieclip (cannon_mc)a shot is being fired (ball_mc)
The longer mouse is down, the speed of wich the ball is fired with should increase.My question to you is;
What is the most efficient way to accomplish this? With a timer or something like this;
[Code]...
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?

Is there any codecs which support transparent background (alpha-channel)?

View 2 RepliesI've designed a Flash site in CS3 using Action Script 2.0 that has a main flash movie sorta floating in space over a gradient background. I want the gradient background to re-size with the browser, so I thought that the easiest way to do this would be to delete the gradient background in Flash and instead recreate the background in Dreamweaver using the repeat background option and then make the Flash movie's background transparent. (I hope I'm making some amount of sense here).
I've found a few tutorials on how to do this, but so far I just get a white background instead of transparent. I've tried choosing "Transparent - Windowless" under Window Mode on the HTML tab in Publish Settings. And I've tried selecting the movie from within DW and clicking the parameter button and adding a "wmode" parameter with "transparent" as its value.

View 7 RepliesI have converted a large background image (much larger than the stage) into a Movie Clip. I did this so I can make it scroll as the player traverses to the edge of the scene.This appears to make the player free to roam the entire background image.I have a tree symbol with a class attached to it that blocks player movement.Here is my problem:
When I drag and drop instances of the tree symbol onto the background, the trees are stationary and do not scroll with the background.I do not want to have to implement code to make the trees scroll when the background does.I was wondering if there was a way to simply attach the trees to the background so that if the background moves, the trees move with it and appear to be part of the background as if they were drawn into it.It is convenient for me to be able to drag and drop as many trees as i need to block certain routes on the background from the player.I tried writing code to make the trees move but it was only working for the very last tree that I added to the scene.
I really don't know much about flash or swf files but in updating my portfolio I came across Polaroid gallery. I have managed to update the background jpeg with my own picture and remove the fade effect. However in the original program the background was tileable so when seen in a full screen browser looked fine. As my picture is not tileable I would like to know if it is possible to scale the background or the whole swf object without tiling the background.
View 1 RepliesI am relatively new to Flash CS3 and i have been learning Action-script 3 over the past week. I have come quite a long way and i have made a site in flash but i just have a question.I have been using an image as my background and i am happy with the way flash automatically scales all the objects in my file but the background image does not scale. Is there a way to do this? I have found out things online which show me how to add auto-resizing to the background but this knocks off the flash auto scaling/resizing for everything else.

View 1 RepliesI have a series of background MCs, all different coloured gradients (pretty!), and a series of corresponding buttons elsewhere on the stage. On a press of each button I would like the corresponding background MC to come to the top of the pile of backgrounds, then fade in above the previous background. The background that was previously on top, needs to stay next-to-top.If the corresponding background is already at the top of the pile, then nothing needs to happen.
At the moment I am using swapDepths(1) which brings the target to the top no problem, but it may also send the previous top layer MC way down the pile.This is what I'm doing at the moment:
on (release) {
if (_root.BG.colour2.getDepth()<=0) {
_root.BG.colour2._alpha = 0;[code].....

When I have an animation, 180 frames long which contains just some small animations and its running at 120 fps no problems. Now I add a keyframe on frame 90 where a large static image pops in. A 1280x800 background image for example, completely static. Then I try to run it at 120 fps and I get a small freeze(0.25s-0.5s) on frame 90. When I add this large image at frame 1 and set visibility to false and on frame 90 I set visibility to true, I have no problems. So the problem should be in instancing the large background object. What can I do about it? Is it possible to get rid of this problem and still keep using the timeline for animations to not hardcode everything because of this?

The swf (AS 2.0) publishes fine and runs OK off the server and in the browser, but the Flash application is slowing down to a crawl making work very unpleasant indeed. Not that it was ever that fast to begin with. The Flash file size is presently 15 megs. It's got a log of symbols in the library and a lot of small jpgs used as navigational buttons, and utilizes many instances of the loader component to dynamically load external files: Is this too much of a demand on the app's resources? I do think that some of this has to do with a poorly implemented user interface (first attempt by Adobe to make Flash "look and feel" like a CS app), but I'm sure there are other issues.

I am working on a flex application. The application occupies 100% of the browser screen, but it is slow to load. How should I improve the performance, what are the best techniques one should follow for improving the performance of a flex App. I did try some stuff though, I am not using relative layout instead i am using absolute layout and putting the buttons/images etc at exact places in a Canvas, still i feel it is slow. Can I profile the App or flex code to see where exactly the app is taking the maximum time to execute.
View 3 RepliesI have quite alots of display objects to manage during runtime, so Im currently using Arrays to manage them. But the problem is I have few many types of displays objects(eg. Tile, Npc and Building) which are basically MovieClips linked to the library. Each display object plays different role where it will be checked on enter frame, a loop.Method 2 sounds much more faster and extensible however Im worried if it would affect the checking rate of each display object during runtime as the displays:Array grow larger and probably making it glitchy.So which one of the following method is faster+less glitchy and explain why you choose it.[code]

I have built an interface that attaches movieclips to the stage in an orderly fashion loopoing with setInterval as well as onEnterframe. All onEnterFrame functions are deleted when they complete their task, same goes for setinterval functions. But yet when I run the movie it taxes my cpu like crazee. I am moving from frame to frame, after clearing intervals, in order to start the next bunch of loops. I am most positive that all setinterval instances are unique and are being cleared respectively. I have no idea why this is happenning...maybe flash is moving to the next frame before clearing the interval?
I have attched a zip file with .fla and an xml file called test.xml....there are a lot of trace actions setup to monitor the execution of the various functions used to clear intervals..
