I'm trying to convert an old project of mine to use Starling for some extra performance.
I've come to a problem when I'm loading my SWFs and trying to display them.
Here is the code I used before: (no Starling)
private function swfLoaded(e:LoaderEvent):void {
var spr:Sprite = new Sprite();
spr = e.currentTarget.content;
bitmapData.draw(spr ...);
}
The problem when I'm using Starling is that the currentTarget.content is a flash.display.displayObject.
cannot convert com.greensock.loading.display::ContentDisplay#90ffec1 to starling.display.Sprite
I want to find a way to "convert" the flash.display.displayObject into a starling Sprite.
I also want to be able to store the loaded swfs content into a array as a sprite.
Thanks in advance,
Tompa
You're overwriting spr with a different value immediately after you create it, for one thing.
After you do the bitmapData.draw() call:
var tex:Texture = Texture.fromBitmapData(bitmapData, false, false);
The new texture can then be used to create a Starling Image sprite.

How do I create the AS3 equivalent of a moviescript with multiple frames?
If I were using the Flash IDE, I would put whatever stuff I wanted on frame 1, other stuff on frame 2, etc. and step through the frames as the user clicks the "Next" button. Or perhaps put in keyframes and tweens and let the system play through the frames at a fixed rate.
I don't see a way to do this in AS3, even though all the descriptions I've seen say that Flash CS3 turns your timeline and frames into ActionScript, and I would like to know how to do the same without having the Flash IDE (e.g., working in Flex).
Let's take a simple example: I have 3 frames. Frame 1 contains the splash page (a lot of text and a button). Frame 2 contains one image, one label, and one button that says "Next". Frame 3 contains two images and one label.
How would you build that in AS3?
Flash CS
You will put your logic code in key frame, and do something with the text,button etc. It's hard for multi uses to edit and work on it.
AS3 use IDE like Flash Builder
Flash CS will is just used to make animation swf
Assume we have a swf named A.swf
A.swf
mySymbol (have a link name like com.mySymbol)
subSymbol1(named subSymbol1)
nameLabel(named label1)
addressLabel(named label2)
subSymbol2(named subSymbol2)
nameLabel(named label1)
addressLabel(named label2)
Here is how you use A.swf in flash builder
Class MyView {
public function MyView() {
var loader:Loader = new Loader();
var url:String = "A.swf";
var urlReq:URLRequest = new URLRequest(url);
var loaderContext:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain, null);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete);
loader.load(urlReq, loaderContext);
}
private function onLoadComplete(e:Event):void {
//now you can get defined symbols in A.swf
var c:Class = getDefinitionByName(" com.mySymbol");
//get a mySymbol instance
var mc:MovieClip = new c();
//add to parent
some.addChild(mc);
/*what you said you got three frames,
Just like set like subSymbol1 and subSymbol2 in this A.swf
add some text in subSymbol1 and other in subSymbol2 */
mc.subSymbol1.visible = false;
mc.subSymbol2.visible = true;
}
}
It could make the program and view indenpendent in a way.
You would most likely just create each of those frames as an individual Sprite.
When you want to switch between them, you'd use removeChild() to hide the old one and addChild() to show the new one.
If you want to get fancy you can add Tweens (either built-in or from a tweening engine). This would allow you to fade between the frames, or scale them in, or slide from left to right, or whatever.
If you need to do more complex sequenced animations you can look into something like TimelineLite to help with that.
I'm trying to see how Starling could benefit the applications I build using as3. My knowledge thus far of Starling is that it only uses bitmap objects not symbol objects. How do I take a BitmapData class and create an starling Image out of it.
This bitmap was a symbol in flash that was converted into bitmap. It then had its properties modified to export for as3
Say there is a Ship BitmapData class in a swc.
According to Starlings documentation of how it handles other bitmap like a png, I would think I should be able to do this.
var myShip:Image = Image.fromBitmap(new Ship());
This of course doesn't work.
fromBitmap() expects to receive a bitmap object but here you are passing in a BitmapData Class. And Image class requires a texture.
Also your syntax is slightly incorrect.
NB. There is Texture.fromBitmap and Texture.fromBitmapData.
Although I haven't tried accessing assets from a swc you could try:
var myShip:Image = new Image(Texture.fromBitmapData(new Ship());
Perhaps try to get the Image appearing first before attempting to access the swc bitmapData
var bd:BitmapData = new BitmapData(100, 100, false, 0xFF0000);
var myShip:Image = new Image(Texture.fromBitmapData(bd);
addChild(myShip); //should display a red square
Working in FlashBuilder, I build a mobile AS3 application that uses a Loader to display a local SWF file. It masks the loader so it only shows a 640x480 window. This worked fine using an old SWF file (a Flixel game, non-Stage3D).
I then tried it with a Stage3D-enabled SWF file. This failed to run, because the application was not set to run in the 'direct' renderMode (it had been in auto up until this point). This allowed the application to run, but the SWF file now ignores the Loader's mask and displays across the entire stage.
Is it not possible to mask Stage3D SWFs when loaded in this way? The loading looks like so:
public function FlixelTest()
{
super();
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
myLoader.x = (stage.fullScreenWidth-640)/2;
myLoader.y = (stage.fullScreenHeight-480)/2;
var url:URLRequest = new URLRequest("stage3dswf.swf"); // in this case both SWFs are in the same folder
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadProdComplete);
myLoader.load(url); // load the SWF file
addChild(myLoader);
}
private function loadProdComplete(e:Event):void{
var gameMask : Shape = new Shape;
gameMask.graphics.beginFill(0xffcc00);
gameMask.graphics.drawRect(myLoader.x,myLoader.y,640,480);
gameMask.graphics.endFill();
myLoader.content.mask = gameMask;
}
As you can read in Adobe's documentation on Stage3D, the special Stage3D layers are located "behind" the regular stage used for 2D content.
Since any mask applied within the 2D stage exists in a different display list, there is no way to use 2D masks on Stage3D content. If at all possible, the only way to get similar results is to use 3D layers and alpha masks within the Stage3D context.
I have Loader object containing loaded swf. I don't know how the shape of this swf looks like - it's not necessarily rectangular.
I want to add some light reflection on it. I need to mask this reflection with Loader, but in the same time I need this Loader to be visible.
I don't want to load swf twice, because it may contain some dynamic, script-generated content, which can produce different results in each Loader.
And that's quite a problem, isn't it? Any ideas?

you could add your instance of the loaded swf to the stage, and for the reflection use he same movieclip/sprite and draw it to a new BitmapData. do the transformations needed and then add to stage.
Or imagine the following situation, instead of having the swf that is loaded adding it's own graphics to library you could do this from the loading application, so for instance, give the instance name of MyDisplayObject to the movieclip in the loaded swf and export to actionscript. After you load the swf you could use the following code to access the library, so you can add this object number of times you need, in you case 2.
here is the code (from adobe live docs)
function initHandler(e:Event) {
var applicationDomain:ApplicationDomain = e.target.applicationDomain; // e.target is the loaderInfo object
var testClip:Class=applicationDomain.getDefinition("testClip") as Class;
var clip = new testClip();
addChild(clip);
var reflection = new testClip();
addChild(reflection);
reflection.y= 100;
}
Hope this get's you on the right track.
We have Bitmap and Bitmapdata objects now. And when using the webcam, we can get raw-pixeldata output from it. But, can we get raw-pixeldata from the "stage" or "swf" object somehow?
I would like to use this to make "small thumbnails" of certain parts of Actionscript applications and these could be complex compositions of dynamic text, bitmap graphics and movieclips at the same time. So it would be nice to make a "quick snap" and just get the current combined pixels into one bitmap and then be able to "save that for later use".
Is that possible? is it too easy? am I just looking the wrong place in the Adobe Docs?
We have images, vectors etc at the same time on stage, so I need to grab the "stage" objects bitmapdata???
Create a BitmapData and call its draw() method with the corresponding DisplayObject
var bmpData:BitmapData = new BitmapData(sprite.width, sprite.height, true);
bmpData.draw(sprite);
If you want to make thumbnails smaller, create a Matrix and call its createBox method with required scaling parameters and pass it to the draw method.
var bmpData:BitmapData = new BitmapData(thumbW, thumbH, true);
var mat:Matrix = new Matrix();
mat.createBox(thumbW / sprite.width, thumbH / sprite.height);
bmpData.draw(sprite, mat);
