ActionScript 3.0 :: Drawing A MovieClip To A Bitmap As Though It Was The Screen?

Jun 23, 2009

Basically, I have a BitmapData object which is acting as a virtual screen.

I have a MovieClip which I want to render to the bitmap using the same transformation as though the bitmap were the screen. However, the MovieClip is not attached directly to the root

The BitmapData.draw() method takes a Matrix as an optional parameter, which I think I need to set as the MovieClip's localToGlobal transformation matrix. However, I don't know how to obtain or construct this!

ActionScript 3.0 :: Drawing From Bitmap To Bitmap Overrides Earlier Graphics?

Dec 29, 2010

I'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

ActionScript 3.0 :: Drawing In Bitmap Optimization?

Feb 11, 2010

today i started some particle generator class that will move particles over the stage via drawing in a Bitmap. Everything works well with low amount of particles, lets say 1000, but for my surprise when i added 10 000 particles the frame rate dropped drastically. And i am saying that since i made the same particle generator using MovieClips instead of drawing in Bitmap, the performance test i run on both classes showed that the Bitmap class with 10K particles on my PC works in around 10-12 FPS, and the MovieClip variation in around 20-21 FPS with the same amount of particles. The particles are identical and both classes are using linked list system to move the particles. So the only logical conclusion is that something is not right with the drawing function.

Code:
private function drawParticles(e:Event):void{
// clearing the _pZone Bitmap of the previous data
_pZone.bitmapData.fillRect(_pZone.bitmapData.rect,0);
_pZone.bitmapData.draw(_blankMc);

ActionScript 3.0 :: Convert A Drawing API To A Bitmap At Run Time?

May 5, 2009

Over the weekend i put together an MP3 player in Flex and just managed to figure out the SoundSpectrum.

It is working as expected.

I am facing problems when it comes to using a bitmap.

Right now, my "Analyser" class pulls the data from SoundMixer.computerSpectrum.

I then use that data with the drawing API to create a simple analyser. You know, just spikes.

Here is the code for that part:

Code:
private function update(e:TimerEvent): void
{
SoundMixer.computeSpectrum(ba, true);
var n:Number = 0;

[Code]....

Ok using common sense here, I am telling flash to take a snapshot of the Analyser and draw it to the bitmapData.

However, i cant seem to get this working. I am not using the dispose() method to clear the bitmap so id expect to see a mess of points (similar to if i removed the g.clear()) but nothing happens.

ActionScript 3.0 :: Bitmap Fill + Drawing API = No Good?

Feb 9, 2010

I'm trying to use a bitmap fill, but I can't seem to get it to work.I'm using FlashDevelop with assets imported from CS4 - this isn't the problem, I can instantiate the asset I'm targeting perfectly fine, so I suspect that it's a problem with what I'm trying to do. Here's my code:

Code:
//get the bitmap data from a grass symbol
//grass symbol IS present - can be added to stage fine
var grassBMD:BitmapData = new BitmapData(155, 80);[code]....

Nothing gets displayed in the box, so I'm suspicious that I'm not allowed to use bitmap fill in non-primitive shapes.

ActionScript 3.0 :: Drawing Small Tiles Into One Large Bitmap Container

Jan 29, 2010

I have a project that is drawing ~10,000 small tiles into one large bitmap container - it's a mosaic. In Flash proper and in FireFox it takes about 20 seconds to complete the drawing. Very acceptable. In Chrome it takes about 1:30 and in IE it takes roughly 3:00 - both too slow to be acceptable to the client - who of course reviewed with IE. I have Flash set to run at 45 fps - and the images are populated by a Timer - at 2 ms intervals. Maybe 2 ms is too fast? But in my testing 1ms was slower as was 3ms, so I kept it at 2. And it works fine in FF and Flash...

ActionScript 3.0 :: Drawing Movie Clip To Bitmap Data - Image Looks Different Depending On Size?

Jul 13, 2010

I've written a class that iterates through all the frames of a movie clip and draws each one to a different bitmap. When I'm done, I should be able to iterate through the bitmaps and play them like a flipbook animation.If I draw all the clips to the same size bitmapdata, then everything looks great. But this is wasteful because now a lot of the bitmapdata's are bigger than they need to be (takes up more memory), and also causes problems because the hit tests don't look right.

So next I try to crop all the bitmapdata to be the smallest possible sizes. However, when I do this, there are subtle differences in the way the images look - the edges might look slightly darker in one frame than in another. When I line up all the images and play them back to back, it no longer looks the same way it originally did.I have no idea why the images look different, and have no idea how to work around this problem, I have tried many different approaches. I have tried using BitmapData.draw(), BitmapData:copyPixels(), and manually using BitmapData:SetPixel(), and all end up with the same result

ActionScript 3.0 :: Force Drawing Onto Screen?

Jul 18, 2010

I am writing a program in AS3 that gradually draws a line following some points on a bitmap.  Firstly I draw the bitmap on the screen ( load into a sprite, add the loader to the sprite and the sprite to the screen) Then I draw the line on it segment by segment.( add an empty Sprite to the screen and then do lots of lineTos)Sometimes my line drawing process goes wrong and I was hoping to see where this happens, but Flash Player 10 seems to have some clever optimisation, so that it waits to put the display on the screen until after it has calculated all of the sections of the lines.  This means that if it goes wrong it never displays the picture, and I cannot see what is going on. This is very frustrating when I use the debugger in Flash as it does not even refresh the screen when it reaches a break point how to turn this optimisation off and force it to draw stuff onto the screen as it is calculated.

ActionScript 3.0 :: Drawing Boxes On Screen Dynamically

Apr 11, 2011

I am very new to flash, and don't fully understand the drawing system yet. I want the user to be able to draw boxes on the screen. This is the code I am using:

Code:
Select all//Declare boxes
var boxes:Array = new Array();
var num:Number = 0;
//Drawer
var drawer = new Sprite();
drawer.graphics.lineStyle(1,0x00ff00);
this.addChild(drawer);
[Code] .....

How can I have the user see the box as they are drawing it, moving with the mouse, rather than just drawn at the end? Are flash's drawings just one time, or can they be dynamically drawn and refreshed?

IOS :: Drawing Images Off-Screen Results In Performance Drop

Sep 19, 2011

Im writing an IOS game using AS3. Here's the problem- I have an image on the screen that moves around. When the image's y value goes negative (the image is partly off the screen), the frame rates bottom out. I've gone over my code pretty thoroughly, even threw together a few test projects just to experiment. In all the test I do, whenever there is an object that is off screen, even partially, the frame rates drop. It's making scrolling backgrounds impossible. BTW, I'm using Packager for iPhone and a 3G (not 3GS). Frame rates are normally 24 with no problems

ActionScript 3.0 :: Bitmap - Adding The Picture To The Screen

I have an issue with Bitmap object. I have a photo gallery which I read from an XML file. Each photo has a path, id and description. When I'm adding the picture to the screen I am doing as follows:

My problem is that when I click the bitmap added to the container I must know what picture this is by getting an id. This way I know what gallery I am to open. A bitmap object does not have this property to be set (id and path). I have decided to create a class which extends Bitmap and then add these attributes within this class. So instead of using a bitmap I would use something like:

Flex :: Force Delay Render Until Receive Data Before Drawing To Screen

Mar 13, 2010

In my Flex application, using a custom control, I am making a JSON request to grab some data from the server. My rendering depends on this data such as knowing how many boxes to draw. How can I either force the rendering to wait until I've got the data before drawing to screen or have the boxes draw once we receive the data? I have an event listener for Event.COMPLETE for my JSON request and in there, I call methods that add to the control. I've tried invalidateDisplayList but that doesn't seem to do anything for me?

ActionScript 3.0 :: Live Screen Capture Webcam Snapshot (bitmap API)?

Apr 10, 2008

Got round to the point where screen grabbing an image and saving it to file is too much, so what i want to do now, is take a snapshot of a live webcam image (I have webcam display working) and display the snapshot/screen grab, next to it or anywhere in the movie. This way the screen capture can be stored temporarily in the movie. once the movie is closed, all info is lost. Once another screen grab is taken, then the previous one is overwritten. The idea is simple but having problems working out how to do it in AS3!

I have got to the idea that i may need to use the Bitmap API to copy a section of the movie, and then redraw it into a new bitmap object?

ActionScript 3.0 :: Replacing A MovieClip With A Drawing?

Oct 27, 2010

I'm creating a platforming game, and I have a fun little water thing set up. My goal is to be able to drag a water object from the library to the scene, and have the water physics kick in when the game starts.
 
To do this, I made the water object a black line, because width is necessary to know how wide I'd like the pool to be.  Within the class I have a heightmap, so then I can connect all the heights together with lines using the drawing API.
 
The problem is, I can't get the original black line to disappear while still displaying the new lines and points Setting the alpha to 0 will permanently make everything invisible.  I'm kind of new to this so maybe it's a dumb question.

Actionscript 3 :: Foreach Drawing Object In Movieclip?

May 26, 2010

I got a europe map designed in flash (1 movieclip, 1 frame, really simple), which contains the map as drawing objects directly inside the scene and in addition some specific countries as clickable buttons. So far it's working fine. What I need now is to make all the other drawing objects clickable without having to edit and script each object. I'm thinking about something like this (pseudo code):

foreach(obj in MovieClip) {
if(obj !typeof(Button)) {
obj.addEventListener(MouseEvent.MOUSE_DOWN, genericClickListener);
}
}

I just don't know the syntax how to achieve that.
