I have searched google for an answer to my problem, but to no results have helped me to solve it. I am trying to find the fastest possible way to load an external .png (as the title suggests). The reason for this is because I want to speed up the loading time of my Adobe Air Application. It loads in a various number of .png files (with transparency) and displays them in a tilelist via Bitmap.

I'm trying to figure out the fastest possible way to load a .png image into a BitmapData object. I am performing multiple processes that do this (load a .png from filesystem). The progress is shown using a loading bar, and I would like to speed up the loading time. Now this process can be called over n number times (via a timer). Right now the method I am using to this is:

I have the following function in my FogOfWar class, it calculates if its team can see the position that is passed on the arguments:[code]My problem is that, with only 3 characters in the game, it can only run 4000 times per second, which is not too much.I can implement a cache, so it caches the most commons positions, but, what else can I do to optimize it?
View 2 RepliesThe question is simple; I need the fastest way to calculate power 2. I need that for this formula which calculates distance between 2 points.var Dist:int = Math.sqrt( (mmx - ox) * (mmx - ox) + (mmy - oy) * (mmy - oy) );
View 2 RepliesWhat is the fastest and most efficient way to get RGBA from an image you don't want to display?
I don't care if it uses air or is backwards compatible with a previous version of the player.
Should I be using file io and reading in the bytes and writing my own parser?
Maybe loadBitmap and getPixel?
Are there certain tricks and optimizations to prevent excess work on the player's side?
I have two Sets. Set b is the subset of Set a. they're both very huge Sets. I want to subtract b from a , what's the best practice to do this common operation? I've written to many codes like this , and I don't think it's efficient.

Is there any Fastest way for this line?
ballAngelRadianVector = -ballAngelRadianVector;
And also this:
ballDegree = fee - ballDegree ;
This code calculates the distance between 2 points by using distance formula, Math.sqrt ( (x1 - x2)^2 + (y1 - y2) ^2). My first point has mmx and mmy coordination and second one has ox and oy coordination. My question is simple, is there any FASTER way for calculate this?

Im using a lot of movieclips in an app.Its hitting the performance limits.Im using .png files in animated movieclips.Looking in the clip it says bitmap as type.. source...pngI used .png because i want the alpha background possibility.I then went into some of the movieclips and changed properties convert to bitmap (althoug technicly they already were according to flash)After this i feel the performance has slightly improved.Is this true or just in my mind & wishfull thinking.
View 3 RepliesI need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites). I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g. Suppose that I have a collection of Sprites (a pool, in fact). Each sprite will be added to the stage and perform some action. After that, it will die. I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage. This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System. A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...
Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc... But, this is JUST ONE scenario...
At the moment I'm trying to use a Object Pool with a Linked List... Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.
how to deal with unsorted arrays to get the next higher or next smaller value?
var _myArray:Array = (1,pizza,2,6,8,test,11,16,17,cola)
_myArray.splice(4,1) // > remove number 8 !
trace(_myArray) // > array contains now: (1,pizza,2,6,test,11,16,17,cola)
how can i get the next higher value (= 11) ?
I've got my 3D sphere to triangle collision detection working now, but I need an efficient method of adding the triangles to the broadphase grid.
This is easy enough if the triangles are smaller than the grid nodes, however - especially given the polycounts I'm working with - it's going to be fairly frequent that a triangle is significantly larger than the grid nodes.
Here's an example.See the yellow polygon? Just adding it the grid nodes by it's vertices results in it NOT being added to 4 grid nodes that it does reside in.
My first thought is repeatedly casting rays along one of the edges from the normal of the edge until you find the intersection point with one of the other edges, of course checking for intersections with the grid edges until you reach the destination intersection with one of the other edges of the triangle. This would work, but is not particularly fast.
Although these triangles aren't being added/removed in real time, only when building the level, when constructing a level with say 100,000 polygons total, I obviously want it to be processed as quickly as possible.
Structure: There is 1 main file that loads external SWF files depending on what is clicked on.One of the external SWF files loads its text from external text files. This works fine when viewing the SWF applet on its own. But when viewing as a whole site, the text doesnt appear. Very annoying.I made that particular SWF on my mums computer running Flash MX 2004The flash file itself uses the Scrollbar component from MX.Could someone tell me why the text doesnt load in this scenario? It runs fine on its own, just not as an external SWF.

How do you load external library objects from an external swf? I want to have an external swf that only contains library objects that are exported for Actionscript, and load these from the master .swf file dynamically during the master swf execution.

View 1 RepliesI'm loading (and unloading) external swfs into a holder in my main document. However, they seem to load perfectly the first time, but after that, they load at a different x and y. I've seen this happen before in someone else's file, but I'm not sure what the solution is.
This is the bare bones of it:

Okay so I am trying to load external swfs which load videos dynamically.
I can load the swfs into the parent fla fine (if I remove all the code and just place a circle or something on the stage of the swf), and the swfs are also loading their respective videos correctly. But when I try to load the external swfs, if they contain any casting related code in them, I'm getting an error
[AS]TypeError: Error #1009: Cannot access a property or method of a null object reference.
at swf1_fla::MainTimeline/frame1()[/AS]
Is there some specific method to casting within external swfs?
My code for loading the videos is this:
[AS]var vc:NetConnection = new NetConnection();
vc.connect(null);
var vs:NetStream = new NetStream(vc);

View 9 RepliesI'm sure this question has been answered but I have been looking everywhere and all I can find is how to load an external SWF but not how to unload it. I come from a basic knowledge of AS2 and it was easy for me to load using levels but I have run into a wall. I have a main swf and to keep the initial filesize small I would like to split some image intensive sections out and load them when needed.

Is there an inbuilt and more efficient / nice way of achieving this? The result does not need to be in the same order as the input - completely unsorted is fine.
Normally I do get by with a lot of R&D, but for some reason am stumped and really pressed for time!An interactive file (say main.swf) is already ready to go.I now need to make this play over a background (say bg.swf) which is a fairly heavy file.
What I'm trying to do it this:Open a new flash document (say "index.fla")- on the first frame, call "bg.swf" by using "loadMovie('bg.swf', 2)"[where 2 is the level number] and then calling "main.swf" by using "loadMovie('main.swf' 4)" [where 4 is the level number]
Now the problem I am facing is this:"bg.swf" is quite a heavy file so takes quite some time to load, whereas "main.swf" is much lighter and loads before "bg.swf" buffers fully.
What I want to achieve is this:Create a new swf file (say "index.swf"), making sure that "main.swf" does not load until "bg.swf" loads completely under it. Note: I cannot make any edits to "main.swf" (which is like a slideshow) file and it is rendered such that it starts the slideshow after 5 seconds.
