I have a bitmapdata object that is filled with n rectangles of a width of 1 pixel and of varying heights.
I want to run through a loop and remove the old rectangle and replace it with a different one.
Should I do something like reset the each bitmap column of pixels to a background color and then add the rect i want?

I'm looking for the most efficient possible way of drawing an 8 x 4 grid (960x600 total size). Each square of the grid has a variable alpha and the grid is redrawn every enter frame. The problem is my application is doing a lot already and I'm looking for the most efficient way to execute this loop 32 times (possible more in fact) per frame without overloading processor.
Code:
private function init():void {
var dimensions : Array = [ 0, 0, 960, 600 ];
var gridRaw : Array = [ 8, 4 ];
var stageRect : Rectangle = new Rectangle( Number( dimensions[0] ), Number( dimensions[1] ), Number( dimensions[2] ), Number( dimensions[3] ) );
[Code] .....
I'm under the impression there could be better ways of drawing the shapes straight to BitmapData without using Sprites, or maybe I'm doing something wrong about memory usage as I can see memory going up and down in a cycle.
I'm using the build in Flex Dataservice to connect to a BlazeDS server. Flex is using the *.fml file within the model folder for the connection details, within that file you can find the following:
<annotation name="ServiceConfig">
<item name="DEFAULT_ENTITY_PACKAGE">valueObjects</item>
<item name="contextRoot">/MYWEBAPP</item>
<item name="rootUrl">http://192.168.178.21:8080/MYWEBAPP</item>

the _super_Database class created by Flex DataService uses that configuration to setup a remote object for communications.Now i'm looking for a way to overwrite those settings within the Database class which extends the _super_Database class.
I'm currently trying to built a little Air Application where I want to set the normal Command-C key to call a function? Is this even possible to use a standard Menu Command?
function createMenu():NativeMenu{
var menu:NativeMenu = new NativeMenu();

menuOneCommand.keyEquivalent = "C"; //Command Shift C
menuOneCommand.addEventListener(Event.SELECT, myfunction);
return menu;
}
Moreover I would love to know how I can call a function (myfunction) which is actually a MouseEvent Handler?
function myfunction(e:MouseEvent = null) {

btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..

I'm afraid I'm going to keyframe out entire sections of animation only for the client to say "Looks great, but can you speed it up just a touch?" and I'll have to rebuilt it all from scratch again.

View 4 RepliesI've been using BitmapData.copyPixels() to draw graphics onto a canvas (Bitmap).I need to rotate the resulting graphics without the use of draw() because it's vastly slower.How can I rotate the target graphic? I'm assuming that there might be a formula or library that I can use which will first reorganize the pixels that make up a graphic based on an origin (point) and radians.I'm pretty certain that I'm not capable of creating such logic, so if there are any known libraries that do this, that would be awesome.I'd like to achieve something similar to XNA's SpriteBatch.Draw() method, which accepts rotation as its 5th argument.

interested (or proficient) in multitouch technology with AS3I'm currently doing a multitouch project (ya!), in which touch point and gesture detection is required, using the beta multitouch API in flash, the program does compile but there're some deadly issues about it:
1. The program(in swf form or windows projector form) lag frequently (about 1-3 times in 10sec) when I'm doing gestures, but it runs withno lagging when I open it by dragging the swf file to IE(and other browsers too), wield. (I'm using win7)2. Swipe gesture is not supported, which makes me really isappointed,by the way, touchEvents and gestureEvents can not be used at the sametime, but I've ever seen some smooth flash programs which apparently allowtouch and gestures, how do they do that?Well, the program is very simple but laggy(except swf in IE, of course), so I don't think the main problem for lagging is my code, I wonder if it's just me or it's the problem of the beta API or Flash player, but it's still not comprehensible

Why did Adobe decide to drastically change the language this much?The only reason I can think to revamp something that before was quite simple to something that is more complex is for efficiency. From what I've seen the listeners help reduce filesize by having you only include functions you need, but it also seems like they're trying to become like larger languages such as java and c++.
While I'm sure it's good code ethics to separate code from movieClips and buttons, it's damn frustrating, coming from the 2.0 background. The only reason I can fathom as to why they did this was because there HAS to be some crazy performance boost or something.
Otherwise it just doesn't make sense to axe it altogether.Maybe I'm just complaining about losing novelties but so far I don't like the changes Adobe has brought to Flash.
for (var k in dictionary)
{
var key:KeyType = KeyType(k);
var value:ValType = ValType(dictionary[k]); // <-- lookup

This is what I use to loop through the entries in a dictionary. As you can see in every iteration I perform a lookup in the dictionary. Is there a more efficient way of iterating the dictionary (while keeping access to the key)?
What way of reading and storing data is fastest for AS3. For debugging right now it is just reading the raw XML, but I suspect it would be faster if I made them into nested arrays. Would parsing the XML into nested arrays to be read later be the most efficient method?, or is there a better way to read lots of data?
