Flash - How To Check If BitmapData Empty

Sep 2, 2011

I have a code to erase a masked movieclip. I would like to know how I can check if the whole movieclip is been erased. So I thought I had to check if the BitmapData is empty. How can I check if every pixel of the movieclip has been erased?

if (erasableBitmapData = empty){
trace("empty")
} var lineSize:Number=40;
var doDraw:Boolean=false;
var resumeDrawing:Boolean=false;
[Code] .....

Xml :: Flash - Run If/else Statement To Check If XML Node Is Empty?

Feb 23, 2010

checking an XML file for a specific node.

Example:

<vid
flv="videoName"
thumb="thumbnail.jpg"
title="Video Title"

[code]....

The first vid node contains a path to a logo graphic, I then need to check in my ActionScript if there is a logo there or not, and to do something if there is(display the logo) I can trace out the logo path so I thought I could run a simple if/else to check if there is anything in that node and if so to do something:

private function thumbOver(e:MouseEvent = null):void
{
trace("
");

[code]....

Now I've tried everything, but it will always trace out "Does have a logo" no matter what I do. I tried:

if (tabData[tabID].video[e.target.id].@logo == "")
if (tabData[tabID].video[e.target.id].@logo == null)

However I get the same results?

ActionScript 3.0 :: Flash Check Container And AddChild If Empty

Apr 7, 2011

I have a button on stage which has a child menu movieclip and that movieclip has three submenu button children.On each of these 3rd level buttons an event listener draws a new container on the stage and adds a new movieClip holding various info.This all works nicely, but I cannot work out a way to get an eventListener on the menu buttons to check if the container already exists so I can then stop the button repeating the add container function. So, at the moment you can repeatedly hit any of these menu buttons and they will just continue to add info movieClip children.I've tried some nice Boolean commands that should work, but I think it's the nesting of the children/relationships that are not allowing me to get this to work.So, basically for arguments sake, let's say I only have one of each item... here's the nesting of children:[code]

Oct 21, 2010

I have 3 input texts on the stage.

ActionScript 3.0 :: Error #2015: Invalid BitmapData At Flash.display::BitmapData()

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..

Actionscript 3 :: Quickly Rotate The Pixels That Make Up BitmapData Without Using BitmapData.draw()?

Dec 29, 2011

I'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.

Actionscript 3 :: Graphic Object BitMapData Type The Same As BitmapData Type?

Dec 29, 2009

The title might be a little misleading. Look at my code and I will explain

public static function loadTile(tileDir:String = "empty"):void
{
if(tileDir != "empty")
{
tPoint = new Point(0,0);
tRect = new Rectangle(0,0,30,30);

[Code]...

I am trying to do tiling with sprites. I want my tiles to be interactive, so that is why I am using the sprite object instead of using regular bitMaps to represent my tiles. You might be wondering why I wouldnt just use graphics.beginBitmapFill(tImage); and graphics.drawRect(0, 0,tWidth ,tHeight ); to pick out the tiles I want to use. Well reason being is because it turns out that drawRect() first and second parameters actually alter the location of where the actual sprite sits at.

So if I set the x and y properties of the sprite to x = 20, and y = 20. then I set my drawRect(20,20). it actually adds an extra 20 pixels to my x and y coords of my sprite. And I know the reason why, I just need to know a better way.

Actionscript 3 :: Check The User Selections On Dynamically Generated Radio Buttons And Check Boxes In Flex?

Jan 27, 2011

The following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?

Flash :: Empty Space After Tweening Movieclip?

Aug 19, 2011

I'm filling arrays from a XML. These arrays have dynamic textFields inside them, and these textFields are childs of a movieclip.

I tween this movieclip, therefore making the array of textFields animate on the stage one by one. There are two sources of XML, one from an actual site, and another from a XML stored in the hdd. First i fill the arrays of textFields, and then animate the movieclip. I do this for the first one, then animate it, do it again for the 2nd one, animate it, again for the 1st one, animate it, so on so on.

myTween = new Tween(mc,"x",None.easeNone,sizeOfStage,0 - mc.width,mcSpeedAuto,true);

my tween ends at 0 - mc.width, the problem is, if i tween first the
"bigger" XML, when the next one which is smaller gets tweened, there's loads of empty space before it tweens the big one again (tweening whitespace?).

myTween.addEventListener(TweenEvent.MOTION_FINISH, onFinish);

onFinish i clear all the arrays (otherwise the tweening of the 2nd one would still have information of the 1st one e.g: 1st has 25 fields, second has 10, 1st shows it's 25 fields, 2nd shows 10, and the 15 that were left from from the 1st one) and call the tween on the 2nd one. I thought that by doing this i'd be clearing all that white space too, apparently not. I think the mc.width just keeps the "bigger" value and always tweens with that, taking longer to end in the 2nd case. I've tried setting the mc.width as the sum of textfield width's everytime i fill the arrays, but this hasn't worked either
