I have created a bitmap that contains the content of a loader.I want to clear the content of the bitmap everytime the loader loads an image.
Here is the code:
var theContent:Bitmap;
function display(xml:XML):void
{
var provider:DataProvider=new DataProvider();

I'm working on a game whose background has many layers that each scroll at different speeds.
Inside each layer I have a Sprite, I've started using graphics.beginBitmapFill, but what I've found is that the graphics.clear() function doesn't actually clear the contents set by the previous call to graphics.begin.BitmapFill. Each frame, I adjust the matrix to shift the layer as needed. Then, I call graphics.clear() and graphics.beginBitmapFill() with the adjusted matrix. Since my layers have alphas in the bitmap, I can see the contents that was drawn the previous frame.
What is the best way to clear the contents out of an array or to reset an array?
Say I have 3 arrays that get populated throughout a specific time. I want to be able to reset or clear out all of the data in the array so it is basically a new Array();
I have added some movie clips to the stage using addChild method on Some Mouse Events.Now on an event say Mouse Double Click I want to clean the stage.I checked the Stage class from reference it does not have any method called clear.Neither I have stored the references of the objects, so that i can clear them using removeChild()
View 1 RepliesI'm creating an AIR 3.0 app.
For a lot of my graphical assets I'm using the Flex embed metadata to embed bitmap objects as Classes and then instantiating them.
The problem is that it seems these never get garbage collected. I haven't found much info online but I've seen a couple of posts that seem to confirm this.
Anytime one of my classes gets instantiated that has these embedded assets, they always create new instances of the Bitmaps and BitmapDatas rather than reusing what's already in memory. This is a huge problem for memory. And I can't find any way of de-referenciong them or getting them to leave memory.
So the only solution I can think is to just load the graphics from disk rather than using the embed tag. But I'd rather not do this seeing as how when the app is packaged and installed, all of those graphcial assets will be on the end users computer rather than contained within the SWF.
I have built a simple Flash application that will be presented using a projector, the application will show messages in the form of questions that will come from a simple flat-file text file or XML file.
In addition to this I would also like to be able to add my own messages using a simple HTML form.
I've been looking around the web for some resources, but have been struggling to find what I am looking for. The basic idea is that the flash application will loop through these different messages from the XML, but then when a user types in a message that will also appear within these messages. Think of it as a sort of dynamic tag cloud.
I'm customizing an xml flash website and while I can handle all the html and xml well enough, but in Flash, I have no clue how to:
Now go on the stage, and delete the contents of the last layer(background & pattern). Here, add from the library, the square movieclip, and name it mcBackColor(see attached image).And then to add your swf background in the "background & pattern" layer from the main.fla file.
I can change the name, but don't know how to delete just the contents of the layer and then add the new clip.I've made a slideshow before and that's all I can do.

I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.
[Code]....
I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap;
var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),
If I have a BitmapData that's already been drawn onto a Sprite. Is there a way to redraw the BitmapData onto a Sprites Graphics object without having to invoke beginBitmapFill and passing in the same BitmapData?
View 1 RepliesI'm working on a game, and to keep performance good, instead of addChild'ing 50 new sprites to the stage every second, I decided to have each player draw to their own bitmap, and then to the 'master' bitmap. This introduces an issue though: the second player would override all data the first player has put into to bitmap...My basic debugging proof of concept:
Code:
// bitmap test

In pure AS3, I have a pixelbender and a large bitmap. The pixelbender is configurable with a distance parameter to affect only a small area of the bitmap.

Is there a way to write a bitmap font right into the bitmap being desplayed? Mabey better worded: myBitmap.draw(image, t) draws a picture is there a way to draw text? I'm stuck even if its just a work around in some way I would like to know... (the current work around i have in my head is writing it in a movieclip turning that into bitmap data and drawing it... esentially creating a prototype answering my question... but a built in way would be easier probably).
View 2 RepliesIn AS3, I am loading a png from a zip file (nochump's zip library through ByteArray to Loader). The png can be up to 45k pixels wide but only 120 tall. This creates a problem in flash, as images can only be ~8000 pixels wide. A possible solution would be to split the images into 6 columns somehow. This would probably need to be done in the ByteArray state, because the limitation is in Bitmap and Loader.
View 2 RepliesI'm using Sandy to animate some objects in 3D. What I currently do to images which are EXPORTED in the library, I want to do to some bitmaps that I create using the DRAW technique. But it wont work :-(

Sandy doesn't seem to treat the 'created' bitmap the same as those that are exported from the library.
Letīs say I have a bitmap with 3 colors: red, green and blue (not mixed)
What if I wanted to make a bitmap of the red part of the first bitmap?
Iīd like to take the red pixels from first bitmap (and its positions), and make another bitmap.
I haven't worked very much with bitmap manipulation and I need to create an app that can find a bitmap (or a pattern of pixels really) in another bitmap.Are there other methods of doing it besides iterating through the pixels and using getPixel()?I'm of course looking for the most effective solution.

I have a project I am working on in which I would like to teach how to cash a scratch off card. I have made the scratch and made it so it will "scratch", however my masking technique seems to not be working how it should...
The idea is that the user would "scratch" the card and then hit "Next" after that it would load a new frame (Progress Bar would move) and then do what they need to on that frame, and so on.
However it would seem that Flash is keeping the users "drawing" and still allows them to draw after the first frame, which is not what I want.[code]...

I've got a video page with an XML based playlist all contained in one swf. I can us flash vars to load in variables to the swf to make it play a specific video (eg.[URL]), if you would like to link directly to a video.Is there a way that when i than click to play another video from within the playlist, that it would also clear the variable from the URL? Or have it update the variable (so it would switch from ?vidID=13 to ?vidID=20 for example), and do so without reloading the swf? (the swf loads with a main video page, which lists new videos etc., and than you can choose videos from the playlist)Right now, when you direct link to a video, than choose another video to watch it keeps the same video ID within the URL... which can be a problem if people just copy the URL thinking that is the correct one.
