ActionScript 1/2 :: Improving Performance With Overlapping MCs?
Oct 29, 2009
I'm having some performance issues in certain areas of a flash game Im making.
Here's the situation: I have big movieclip containing a map that can be scrolled and scaled. There are some pannels with a bunch of MC buttons, controls, etc. on the right side of the stage. These are seperate from the map and stay in the same place.
Everything runs fine untill the large map is zoomed in and/or scrolled such that the right side buttons and stuff are overlapping them map. Then the framerate jumps down from a nice smooth 30 fps to about 3 fps while the map is moving. There are no issues with the map moving when they don't overlap.
Now the thing is, is that's there's no real interaction between the buttons and the map. No transparency or anything, in fact I'm perfectly happy with the map dissapearing behind a side pannel. There are only about 3 pannels that the screen drawing routine would have to worry about, as all the buttons rest on top of the pannels, so why is my performance taking such a hit?
(Hmmm. Actually I do have a lot of transparency, but each is on top of a solid background, and none interact with the map.)

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?

rendering performance when scrolling some content. I have a large sprite with a lot of content that I need to scroll and the problem that I am encountering is that when scrolling this big sprite, the rendering of the Flash Player seems to slow down and the movement is choppy. I wrote a custom scrollbar class that simply updates the target sprite y or x properties on an enter frame event. The large sprite that I am scrolling mainly contains other sprites that have drawn shapes, loaded bitmaps and text fields.
Considering that I am simply moving the sprite, there are no other animations happening, nor other intensive processes at the same time, I do not think that it should be that resource intensive as to slow down the Flash Player that much. What can I do to improve the performance when scrolling the sprite? (Just to give a rough approximation, the sprite that I am scrolling contains around 20-30 sprites with drawn shapes, 2-5 loaded bitmaps, 5-10 text fields.)

I am using a custom Flex skin to create an active blur/frosted glass effect on the background of floating Panels, TitleWindows, and other containers (similar to http:url....). There is a background image in the Application skin, and potentially any number of other components above and below the active blur component. Here's some relevant code within the skin:
public static const BLUR_FILTER :BlurFilter = new BlurFilter(16, 16, BitmapFilterQuality.HIGH);
private var _bitmapFill :BitmapFill = new BitmapFill;
private var _matrix :Matrix = new Matrix;[code]....
Unfortunately, the performance of this when the component is being resized, and especially when moved, is poor. There is noticeable drag delay and overall slowdown, and this is with only one popped-up TitleWindow in the test application. There is especially poor performance when components inside the TitleWindow are changed (button hover states, etc.)I've attempted to optimized a little bit by avoiding reinstantiation of the blur filter, bitmap fill, and matrix, but this has had little or no effect. I removed the blur at one point, just drawing the Application to a bitmap, and the performance is still poor, so it's clear that it's mostly the BitmapData.draw() call.
I've read about using scrollRect and cacheAsBitmap, but I'm not sure where to apply these properties (or other optimizations I'm not aware of) within the Application or its components.

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;

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?

So I have made a basic slideshow on flash for a website. Nice but simple, 3 images fading in and out. But I want to make a slideshow that moves either vertically or horizontally, but most likely at an angle. I also want some text to either fade in or move as well. So I have a few questions.1) What is the best way to get th pictures to move at an angle? I have read some xml options for editing in dreamweaver, can't seem to find one for moving the picture.I would imagine you have to edit it in flash? Yes I'm new to flash!2) I take it you edit the text in flash, could it be dynamic text and what is the best way to move it?

I'm used to the drawing tools within CS3/CS4, but i tend to draw from with AS3 using the drawing API, this is because I tend to want to programmatically animate the drawing parameters.Is there some solution whereby you can use the drawing tools within flash CS3/4 but then 'capture' the drawing information so you could then draw the same line/curve/ shape from within AS3?So a pentool could then give a code output like:
lineStyle(..)
moveTo(...)
lineTo(...)

So i'm building a plugin system for my game, and i need to know actively what objects each plugin wants to use. For this, i have made a simple String interpreter. What it can do so far is separate id's and get whether a required input uses all of that kind.
my input format is like this:
Code:
IA:[param];IA[param];NN
IA is the index of all objects matching the parameter to the right of it. A is replaced by A if you want all those objects with the ID of param, or a number for a specific index.:[] tells the interpreter that what is inside the ['s is the param.the param is the string identifier that it looks for when finding objects.NN is the end sequence. this tells the engine that it doesn't need any more params.so say i had a plugin that uses the string
Code:
I2[player];IA[world];NN
the engine will loop through all objects with the ID "world" using them as the second param for the plugin's behavior, and the first will always be the 2nd "player" in the list.I can currently detect whether it wants all of a certain parameter, and what the parameter is. Now, i need to be able to find the index each param requires if it is not all. And i've tried multiple ways of doing this, but none so far have worked. What method would i use? Also, if you see anything that would kill performance in the interpreter, i would love to know, as this is called every frame.
My current code is a class with static methods called StringInterpreter, with the below code:
Code:
package Utils
{
public class ScriptInterpreter
{

Notice the animated "I"s in the top right... this is an MC with different instances of an I with a code in each one that animates it then resets it at a random size and alpha.If you scroll over the main menu buttons of the site and watch the animation sometimes it pauses for a bit. I have even removed many of the "I"s I had origonally and it still slows up a bit. This became more noticable when I added sound to the menu buttons.

I have a program in which I am running a number of for loops which are doing a number of different things.I pull in data from an xml file and then step through that data to dynamically create arrays, populate the arrays, and create and modify movie clips.
The program I'm building is similar in scope to one I developed in Director many years ago, and in that environment we had to actually put breaks in using timers to ensure that the data would be processed and that the system wouldn't choke.
What I'm seeing with this flash version of the application is similar and I suspect the same. Basically, when navigating from the frame where the scripts are processed to the frame where the movie clips are displayed, there are times when it works perfectly and times when things are out of whack. I put in a 5 second delay (arbitrarily) to see if this would resolve the issue and on my system at least it does. But I need some advice on coming up with a real solution.

I have an html website that displays still photographs contained in a swf built in flash. I refer in particular to the images in the rectangle window on the right. [URL]As you can see the swf starts with a % preloader. The images are fairly high resolution, 14 in total (each embedded into movie clips and not dynamically loaded)I just wish to know if there is a way of SPEEDING up the time it takes for the swf to load and open in the web page, to aid users with a slower connection.I understand that if my host server is reaonably fast (which I believe it is) then the problem lies with the users connection speed, but IS THERE ANY ADD ON ACCELERATOR or CODING I can apply from my side of things ?

I'm working on a game where clicking an object causes cartoon animals to appear. The animals stick around and do a little animation for about 5 seconds, before disappearing. I'm having a problem where if I click the object before the animal disappears, another appears on top of it.This is my code:
on (release) {
i = Math.ceil(Math.random()*3);
if (i == 1) {[code]...........
I'm trying to find a way to make it so "on release" is disabled for a set period of time once it executes, enough time to ensure the animal movie clip playing has disappeared.

I have a movie clip with hit zones over buttons. It looks like a cam corder and when you roll over them a thumb moves to that button and when you click. The thumb presses on the button. That all works great. I want to put buttons in the main scene over top of these that will change things on the screen when you click it. And get urls of the videos that I have on my website. But when I put the hitzones over other hitzones the ones in back dont work. Is there a way to make them both work or am I going to have to make everything contained in the movie clip? So in short can I have two buttons on top of each other that do two different things?

This seems like such an easy thing to do but it's driving me crazy. Sorry if this is a simple question. In a site I am building it is necessary to have a large movieclip overlaid over an image gallery. This movieclip controls scrolling so has a rollover listener attached, but of course the gallery pictures also need to have button actions. I cannot get them both working at the same time. How can I make it so that rolling over a movieclip doesn't disable the rollover for any movieclips underneath it? Here is a very simple example of the problem. Where the two buttons intersect, I want for the rollover to trigger them both: [URL]

I'm using the drawing API features to do the following: I created two different squares and want to use them as two different canvas to draw on, they should be on top of each other so for testing purpose I overlap them partially here, but somehow I'm having trouble when trying to draw on the overlapped areas. Has any one encountered this problem or know how to solve it?

I wanted to know how to write As3 so that the sound that I place on a timeline doesn't overlap? Or is it best off the timeline? I've tried putting each song into it's own place on the timeline but there are labels and when a new song plays, the old one continues. If I just have one song on the entire timeline, whenever I move across different labels, the song overlaps.

I've created a banner and made the whole area clickable with an invisible button. But there's one small element in that banner I'd like to give a roll over state for extra fun. This element doesn't need a link hooked to it just to change colour when moused over. When I put the invisible button on top, it blocks the element on top the invisible button is not working either. Since it's a banner I have the document set up in as2.

This only happens if I've just launched IE after being restarted and goes away once I refresh the page. I even added a jQuery $(document).ready function that sets a margin between the html and the flash content to add 1px of space when the page is loaded. It's so hard to figure out, because once I refresh the page, it goes away.########### SOLVED ###################### SOLVEDI set the flash output as a javascript var (actually json_encoded PHP output) and on document load inserted the object into the "flashContent" div with the jQuery.(document).ready event.
