Actionscript 3 :: Rendering Flash Menu Over The Top Of Game Drawn With CopyPixels
Feb 20, 2011
I'm new to flash but have plenty of experience developing games, so when I started in flash I ignored pretty much everything that flash could do and just created a buffer the same size as my flash movie and drew my game direct to that with copyPixels. Now what I want to do is to add a menu to the game and it seems sensible to do make use of flash a little more. I can build a menu no problems in a .fla but can anyone tell me how I can render it over the top of my game?

I got a .fla file, which i have to edit. The file is used at a website, and contains the menu.Reads input from xml file.I can make the changes, logo and some static text.When publishing the file, the menu appears as pink boxes instead of rendering of the menu.There is not outpur errors, and everything else works as it should, just not the menu.

im creating a card game. i have a seperate timeline for the menu bar. ive placed this code on the first cell of the timeline:
Code:
import mx.controls.Menu;
import mx.controls.MenuBar;[code].....
the problem i get is that when the user selects "new game" it should restart the game. when it does this the toolbar is not reset. instead a new menu item is added (without removing the old one. so evertime the user hits new game, a new "file" menu is added). how do i make sure there is only 1 "File" menu? and im using actionscript 2

I'm not much of a scripter. I get by editing scripts similar to my needs. I learned a few things about blitting and I'm trying to get a rectangle area of a MovieClip to blit to a location on the stage. But I run into the error "Invalid BitmapData" which makes sense because I'm referencing a MovieClip and not an image. Is there a different AS3 command other then copyPixels that would work for a MC?
I know VCam would seem an obvious solution, however VCam scales to fill the entire stage. I only want to fill a small rectangle on the stage. I've already attempted to edit VCam with no success. Its probably not the same principle, but would it be possible to blit the matrix VCam uses?

I have a BitmapData object with transparency (the sourceBitmapData parameter). Every time I use copyPixels() to copy it onto another BitmapData object the transparent pixels replace whatever is beneath them. I would like the copyPixels() function to simply ignore these fully transparent pixels (0x00) and NOT copy themBTW, I've tried setting the alphaMerge to true but that doesn't solve the issue - the whole source object just goes black and ignores ALL transparency.EDIT:
Here are the code snippets;
var b:UIComponent = new UIComponent();
b.graphics.beginFill(color, opacity);

I'm loading a batch of 50 jpgs and once loaded, on enter frame, I'd like to change their alpha individually and apply BlendMode.ADD to all of them (also individually).
I can do this easy using normal Sprite objects, but this is not efficient enough (processor wise). I've played a bit with BitmapData.draw(source, null, null, BlendMode.Add) and that's still not efficient enough.
So I was wondering if I could achieve similar effect using copyPixels (which I know should be more efficient). Still, I'm a bit clueless on how could I apply BlendMode and alpha on a bitmapData object (I mean, I know I can't, but I was wondering if I could make this work using Matrix and filter manipulations).

I have a 50x50 fixed rectangle in the center of the stage. I am using this rectangle as a "hit area" to copy pixels of a bitmap that is draged by the user to line up an area of the image he/she would like to crop.I have preview of the hit area displayed while the bm is being dragged which works well. However, once the bitmap is scaled using the slider component the preview area no longer reflects what is in the hit area.
Code below:
function mouseDownHandler(e:MouseEvent):void
{
// Contraint #8 - Define drag bounds[code].....

why I didn't put it into games category. I've got a game, it's mostly OOP. I've only one frame with "include" statement and the rest is in classes. Now I'd like to do a menu.Can I somehow separate the code of buttons inside menu? I add new frame with a menu MC inside and the "stop()" code. The "start game" button has got this code inside:
Code:
on(release)
{
_root.gotoAndPlay("2");
}
In frame 2 there's a playable part of my game. It works but... Can I move this code somewhere else so I can manage all buttons in one place? I tried:
Code:
_root.menu.start_button.on(release)
But it's not working (as if it should...).

I have a menu for a website in flash where, an mc moves up and down and shoots...so that when the projectile MC hits a button, it clicks it.
1.) How do I make it so that the MC follows the mouse (like a custom cursor)..but is restricted to only going vertically
2.) how would you make it so that the mc can shoot anywhere....but when the fired MC hits a button, it acts as if it was clicked? My AS knowledge...is..very basic...so if you have any free time could you explain the codes?...so that I can learn from this...rather then just stealing your codes... but..if you want to just let me copy and paste...thats cool too

I did a function for blit scrolling successfully using Draw(), but then I heard that copyPixels is faster. Unfortunately, I'm not having the same success with that as I had with draw();
Specifically, no matter what I try to use for the source image, it keeps saying that it can't be coerced into a bitmapData object:
Code:
TypeError: Error #1034: Type Coercion failed: cannot convert SourceBitmap_bm$ to flash.display.BitmapData.
I tried referencing the bitmap in my Library (That's how I'd prefer to do it, copy from an item already sitting in my library) that has base class "flash.display.BitmapData", yet I get the error. I tried putting the bitmap into a movieclip and copying from that, same error. I tried copying from an offscreen instance of the mc (which worked fine with draw()), same error.
It's a mess by now because i've tried so many things, but this is my code:
[Code]...
I see are for copying pixels after loading in an external file. Does anyone know of an example that works with items already in library?

I need to load a very big image on AS3 (currently sized at 8192x8192). I am aware that it does not fit any of the limits imposed by Flash regarding drawing to screen or creating a BitmapData of that size. I just want to load the image so I can copyPixels() some parts of it here and there.The thing is, I'm loading the .jpg file of that size with no problems. The size is recognized correctly from my Loader object. I load it like this:[code]But I am greeted with the #2015 "Invalid BitmapData" error usually reserved for BitmapDatas that are too big. The error also happens if I try to do a copyPixels(), which is what I need to do.Is there any workaround I can use so I can get data from an image this big on AS3?

How would I go about using CopyPixels to build an isometric map? CopyPixels takes a specific rectangle and copies that onto a bitmap.. But how would one use that to build a seamless isometric map?Building a square top-down tiled map would be very simple as copypixels pastes each tile next to one another.. But for Isometric Maps, this would be different as some parts of the CopyPixels rectangle is over lapped into other tiles.. and this would 'erase' the bitmap of the other tiles currently on the bitmap..[URL]Fig2, is what happens when you try to do a copyPixel over an existing bitmap, assuming the white is transparent space.

I want to use numbers I've drawn myself to represent a number, but don't know how to implement this. How would I display the equivalent of an integer with these numbers? If it's necessary to have them in a tile pattern, which makes sense to me considering how older games worked, then what code would I use to switch between each? Or is there another, better way? Also, I need the number to be able to adjust to the number of digits in the number and read from left to right (so the 1 in 10 would be in the same place as the 1 in 1).

Traditionally, when blitting in old 2d games, flips and 90 degree rotations could be achieved with almost no performance hit. The reason for this is that the effect an be achieved by simply changing the order that pixels are copied.
I'm using copyPixels in Flash to get maximum performance. Is there any way to do a flip or 90 degree rotation using copyPixels? (Without pre-calculating and storing the flip/rotate). I couldn't find a way to do it, but it seems like it should be possible, because it is a very common technique in 2d games (well, not so much now that modern 2d games use 3d hardware acceleration... but Flash doesn't let us do that, so we need to use the traditional 2d techniques)

I am making a custom renderer using the copyPixels function for my Haxe/Flash game. So I have this kind of code :
buffer.bitmapData.copyPixels(m_CurrentSkin, RECT3, POINT, null, null,true);
where :
-buffer is the bitmap where all my scene's objects are drawn
-m_CurrentSkinis the BitmapData that contains the current frame of the object to be drawn
Every time m_CurrentSkin contains a BitmapData that have never been drawn (the first time that an animation frame is drawn for example),I have a memory leak that is not garbage. However if m_CurrentSkin contains a BitmapData that have already been drawn (when the animation is played a second time for example), there isn't any memory leak.If I comment this line there is no leak so the problem comes from there.It seems that a copy of the BitmapData is cached in memory but I have checked in my code and there is no cacheAsBitmap explicitely set to true.

I am playing around with an old Zelda: Link's Awakening tile set, and was trying to make an application that will display the current selected tile.
I am well versed in as2 but have never had need for the bitmap classes until now. I have found examples of the copyPixel() function that work but could not get it to work in my code.
I have attached the .fla file I saved it as a CS2 (Flash 8) file. (I use CS3 and/or CS4 depending on which computer that I am currently using. This one is in CS3)

I'm working on my second flash game and have been stopped in my tracks trying to cache MovieClip Animations into arrays of BitmapData frames. To capture the frames I have set up a loop which runs through the frames in the MovieClip and use copyPixels to get a snapshot of the graphic.This works fine if the MovieClip to cache does not contain any child MovieClips, but if it does, these MovieClips are frozen on their first frames. I've been looking at MovieClip.getChildAt(index) in attempt to navigate their time lines but because that returns a DisplayObject it seems impossible.
So, my question is: Is it possible it to use copyPixes on a MovieClip and also step through child time lines, or should I be using sprite sheets?

I am trying to find a way to render a Flash object, more specifically a Open Flash Chart, in the server, and save a screenshot of it to a temp file to embed it in on a PDF report.
I've found some solutions that use Javascript to generate a temp file in the browser, and then send it to the server (like here). However I need to generate reports automatically and send them as e-mail attachments, so I cannot render it using a browser.

Is it possible to use copyPixels to capture part of the stage directly into a bitmapData object?
Just wondering because in my situation using captureBitmapData.draw(stage, matrix); is causing performance problems, even without the matrix. I read that copyPixels is fast so I was wondering if there's a trick to use that directly on the stage without the draw part.
What I'm essentially doing is screen capturing a part of the stage and putting it in a a window, using a loop to update it over time since it contains animation. Works great in one of my FLAs, but chugs in the other so looking to optimize the code to a bare minimum.
