AS3 :: Performance Many Arrays Vs One Array + 'is'
Sep 2, 2010
I 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 need to add one array to another (only care about saving the joined one). Which is the preferred way of doing this? Speed is the primary concern followed by readability (I consider Option 1 to be a cleaner option). I assume it might also depend on the length of the arrays, but are there any good guidelines?

I am running into some trouble adding an array into another array to create a multi-dimensional array.The code appears as below:
var slideDataArray:Array = new Array();
var slideShowDataArray:Array = new Array();
slideDataArray[0] = xmlData.SlideShowParameters.SlideShowImagesDirectory;[code]........
I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.

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?

Long story short: I want to search a multidimensional array in AS3 for (in this example) the location of 6 strings - all of which are stored in another unrelared array. Long story long: Once I get the locations (in the multidimensional array) of each string, i then know where it's located, and can access other atributes of that object - so if i found the string "box3" is located in element [5] of my multidimensional array, i can now target: multiArray[5][3] to return the 4th item stored (keeping in mind we're starting from 0, so 3 is the 4th position).
I can get this to work once, but I'm trying to set up a for loop based on the length of my basic string storage array - this array holds (in this example) 6 instance name strings - each time my for loop loops, i need to run a search in my multdimensional array for the next consecutive instance name. Then, once I've located all of them (and store the results in a new temporary array) I can dig around in each location for the info I need.

I need to change a text field every time values in an array is updated, and I tried putting the code in the setter. However, the code is not being called. Even if I do this
public function set resources(value:*) {
//this function does not seem to matter at all
}
Nothing happens. I think AS3 overrides setters for arrays, how do I get the functionality other than inserting a changeTextFields(); every time I change the array?

I get an output of of 3. the number of variables within the first array, this is not what I had expected.

I have an array of movie clips (representing band members) which have various properties, among them them a property which tells where the band member went to after they left their current band. For those who formed a new group, I want to create an array. Within that array, I want to group all the ones that left for the same group into secondary arrays. So, if you had five band members and 2 of them left for group X and 3 left for group Y. What's the best way to do this? This is, roughly, my code:
[Code]...
Alternatively I suppose if I could do without a multidimensional array and just loop through all the members and say - for those members whose group is the same, perform this function, with the name of that same group passed as the parameter for the function. I guess the trouble I'm having is identifying who's the same.

I have movie clip in an array (newStep) that is being added to the stage dynamically. It's randomly choosing a frame to go to every time an instance is added. There is a nested movie clip (stepLine) that i need to change the alpha of. This code actually works for adding a string to to the dynamic text box (pointsDText) but when i try to access the nested movie clip (stepLine) it gives me 1009 null object reference error. The funny thing is the code actually works and does change the alpha of the movie clip but i still get that error, and i think it's making my game more glitchy. I've tried using if(contains(steps[r].stepLine)) too but it doesn't work. Is there a better way to access this movie clip without getting the error?
if(newStep != null){
for(var r:int = 0; r<steps.length;r++){
if(steps[r].currentLabel == "points"){
