ActionScript 3.0 :: Changing The Background Pixels?
Dec 28, 2010
Coming from java I could manipulate the background pixel by pixel as well as read color values of a certain pixel at coordinates (x,y).Now in flash I seem to be able to load a bitmap image. But I need to change the background color and also be able to read the color value of pixels.
My flash movie size is 800x600, sometimes bigger.I am trying to do simulations (biology) of a moving object leaving a trail (changed background color?) Then other moving objects can detect that trail (read background color) and increase or decrease the color value.

This has been bugging me for a little, and some of the examples I have tried to find throw me in loops and they have been wrong. [url]...
Or if you have ever played "Scorched Earth" you will see that when some part of the terrain is destroyed, it punches out the pixels perfectly when a shot is fired into the ground, to reveal the picture behind the main picture with the terrain.

im trying to draw opaque pixels on a transparent bitmapdata background
heres the ex:
ActionScript Code:
//TRANSPARENT BACKGROUND
var _pixelColor:uint = 0x9998002E;
var _bmpd:BitmapData = new BitmapData(4, 7, true, 0x00333333);
[Code].....
This example paints 2 arrows, the first is using the transparent background, and the second is using an opaque background on the BitmapData.
What I'm trying to achieve is to paint the pixels of the arrow completely opaque on the transparent background. But as you can see, the pixel is at 99% of its opacity (var _pixelColor:uint = 0x9998002E) How can I paint 100% opaque pixels on a transparent BitmapData "canvas"?

I'm trying to get a modal window working, but for some reason, no matter what I do, the only part of the movie that's modalized is everything but the bottom 50 pixels; apparently the background transparent rectangle thing isn't being made high enough for whatever reason. Does anyone have any ideas of what's going on? A demo .fla of the apparent bug is attached.

so instead of the pixels being dissolved, the pixels being added? :
ActionScript Code:
var Anim:TransitionManager = new TransitionManager(blackbox);
Anim.startTransition({type:PixelDissolve, direction:Transition.OUT, duration:1, easing:None.easeOut, xSections:35, ySections:35});
basically what i would like is the end point to be the start point and the start point the end point.

I have a swf file that loads into my main movie, and within that swf there is a masked image that i would like to scale using zoom in and out buttons and also by using a slider bar.However i cant find any tutorials that will allow me to combine the two.I have used the following code for the buttons. Which seems to work ok but i would like it to be a little smoother. (using speed or some sort of easing??)
ActionScript Code:
zoomPlus.onRelease = function(zoomIn) {
if (test_shirt.shirt._xscale == 400 && test_shirt.shirt._yscale == 400) {[code]....
but for this code it keeps shrinking my initial object down to 10 pixels by 10 pixels..

I have a movie clip called column1_mc. when I click a button I need to move the movie clip in incremental moves consisting of 30 pixels.
column1_mc._y = 30;
Does not work because that is giving a _y coordinate.For example.I need to make the movie clip jump to _y 300 but make 10x30 pixel incremental jumps. Moving 10 times 30 pixel jumps.

I have a Component that has a specific background image. The code looks like:
<mx:backgroundImage>@Embed(source='img1.png')</mx:backgroundImage>
<mx:states>
<mx:State name='state2'>
<mx:SetStyle name="backgroundImage">
[Code]....
But when I change the state to 'state2', it doesn't actually change anything.

I am developing an AIR application and I want to change my project theme to one of the additional included themes that is packaged with Flash Builder 4. So, I went to the Project Theme and changed it and it looks like it is supposed to in the Design View. When I run the application, the components (eg: a button) themselves look like it is supposed to, but the application's background is just white instead of the displayed color in the design view.

I'm building a site that will change the background depending time of day. I do want to show the time in the top of my page. What are good codes for showing a time and date in Flash and what would I use to change background depending on if the time is past 7PM or before.
Example.
If the time is before 7PM I want it to show a background with a clear blue sky. If not then the background will be a starry night. I'm using CS3.

I made a movieclip that has 3 plain color thumbnails and 1 image thumbnail pop up when my "change theme" button is clicked. I can't figure out how to go about changing the background color/image when the appropriate thumbnail is clicked. I know I need to set up an addeventlistener, but I don't know where to go from there. Maybe I need to have Flash load a new CSS file for every thumbnail clicked?

I wanted to put there a background that will change (fade out and than fade in another one) according to menu position. It would load external *.swf's. For example I'm in "A" and the background is "bg01.swf", after clicking "B" the "bg01.swf" background would unload/stop (fade out) and than the "bg02.swf" would fade in and start to animate. I can't put the right script in the menu system. The source files are attached to this post (Flash CS3 source file and the backgrounds):

I've used script -[URL] to open a centralised window on the release of a button. It works brilliantly but how to change the background colour of the opened window to black. I'm no programmer so don't really have much of a grasp of Action or Java script but having looked on the web, I think what I need to do is use document.bgColour('#000000') somewhere in the script but have no idea where to put it or even if it's right!

I have just started working in flash and I am having some trouble with a Flash XML Slideshow that I had purchased from "Flash Den". My problem is that I would like to add an element in the XML file to change the background color everytime the slideshow changes to a new slide. I have downloaded the xml gallery from this forum and it works great but on my home page, I would like the same function but only without the thumbnails because my client would like the slideshow to be on the home page but without any thumbnails. She would also like the background color to change as the slideshow changes.

I would like to have flash www page with dimentions 960x653 pixels. There will be 5 scenes navigated by buttons and each of the scene will have different background color. I would like to have fullscreen background also (filling the rest of the space), and to make it I used "Auto-Resizing and Centering Content", based on tutorial:
[URL]
To make it working with my existing animation I made 960x653 UILoader instead the centerRectangle, and I loaded my swf animation there. Fullscreen background is working - when I scale window of the viewer the main scene keeps its dimentions and background fills the rest of the space, what is what I wanted to. My included animation is working perfectly.
But I still have one issue to solve. How to change my fullscreen background while switching scenes? Is it possible to change it from included swf animation?

One of these scenes is a page whereby when a user clicks on a button he/she can change the background image on every scene in my project.On each scene i have made a layer called 'background' and drawn a black rectangle which is the default background. This has been converted to a graphic using F8.What i'd like to be able to do is when the user clicks on the button he/she can change this default background to 1 of 4 photo's i have in my library.i have tried the code:
