I have an object which is coded in a .as file, let's call it a widget, in widget.as. It is listed in the library as a MovieClip and is in fact a MovieClip. How can I, from the code in widget.as, overlay an image (Bitmap) from the library on it so that the Widget has four parts which can be switched between two different styles independently.
As an alternative, I could make a frame in the MovieClip of Widget for each possibility and make the code switch what frame I am on.
This must work in Adobe Flash CS3 and with ActionScript 3
If you have the image you want to show on top of it, and already have that split in four, then you could do something like this:
var tl:Bitmap = new Bitmap();
var tr:Bitmap = new Bitmap();
var bl:Bitmap = new Bitmap();
var br:Bitmap = new Bitmap();
addChild(tl);
addChild(tr);
addChild(bl);
addChild(br);

I have a problem that after a lot of searches I didn't manage to solve it.
I created 2 movie clips in the library (let say mc1 and mc2). Then I manually create another movie clip in timeline (using IDE), let say foo.
As background inside foo I use mc1 with instance name bg. In ActionScript I'm trying to replace the foo.bg with mc2.
Please note that I already exported mc1 and mc2 to first frame with classes mc1() and mc2().
I tried (without any luck) :
var mc1:movieClip = new mc1()
var mc2:movieClip = new mc2()
if (....)
{
foo.bg=mc2;
}
Thanks
Mistake №1: managing objects in display list is not the same thing as assigning variables.
Mistake №2: variable names and class name MUST be different. On a case-level, at least.
So, you need to do something like that:
var mc1:MovieClip = new MC1;
var mc2:MovieClip = new MC2;
// ...
// Delete existing background.
foo.removeChild(foo.bg);
// Set the new background.
foo.addChild(mc2);
foo.bg = mc2;
Ok so i'm trying to display multiple instance of an object square(movie clip) on different location on screen.
var k1=0,k=0,p=0;
for (k1=0;k1<5;k1++)
{
drawrect(k,p);
k=k+101;
}
This above code is for number of times i want to display the object om screen horizontally in line.
import flash.display.MovieClip;
function drawrect(x1:Number,y1:Number){
// statements here
trace("Hello world!");
var MC_squre:MovieClip= new MovieClip();
MC_squre.x=x1;
MC_squre.y=y1;
addChild(MC_squre);
};
this Function is trying to declare instance of movieclip SQUARE and place it at given parameter in function.i might want to make it and array of the instance later too.i tried this code with just
var square:Sprite = new Sprite();
addChild(square);
square.graphics.lineStyle(3,0x000000);
square.graphics.beginFill(0x0000FF);
square.graphics.drawRect(0,0,100,100);
square.graphics.endFill();
and it worked but i want to now use it by library object not just on drawn shapes.
What you have to do is to make your object in the library accessible by actionscript.
To do that, go into the properties of that Clip, click on "Advanced", and check the box "Export for Actionscript".
When pressing "Ok", you will get a warning that such a class does not exist and it will be automatically generated. That is ok.
Whatever you put as a classname in the Properties, you then have to use to instanciate your objects. If it is for example MySquare, use that.
So your above code would look like this:
function drawrect(x1:Number,y1:Number){
// statements here
trace("Hello world!");
var MC_squre:MovieClip= new MySquare();
MC_squre.x=x1;
MC_squre.y=y1;
addChild(MC_squre);
};
I have to do a very simple swf application able to show a series of pdf files.
Actually I was able to create on a single layer the menu interface (some buttons on frame 0 which redirect the user to other frames where the pdf should be showed).
Here my question:
I need a way to read the pdf inside the flash frame.
I've found a possible solution converting the pdf into an swf with FlashPaper 2
Now I wish to know how import the swf into the frame.
Reading some actionscript 3 guides I was able to create a container movieclip (a simple rectangle) into which I have loaded the swf with this code:
var swf:MovieClip;
var loader:Loader = new Loader();
var defaultSWF:URLRequest = new URLRequest("test.swf"); //test.swf is my converted pdf
loader.load(defaultSWF);
screen_01.addChild(loader); //screen_01 is the container rectangle converted to movieclip
I've used a container movieclip to mantain the other objects (menu buttons) on the frame, and ecause it helps with the swf positioning.
I seen it is possible also using loader.x and loader.y and it works.
Unfortunately I wasn't able to control width and height of the swf/pdf file (loader.width and loader.height exists but if used cause the swf will not loaded at all)
Solution:
I've found a possible solution at this page. The idea is to change swf scale only after the load process is complete (positioning can be done even before).
Anyway I had to use Actionscript 2 for this project because FlashPaper converted pdf doesn't work properly with AS3, I don't know why...
here the code:
//insert an emplty movieclip to load the swf, I've called it screen_01
var movLoad:MovieClipLoader = new MovieClipLoader();
var myListener:Object = new Object();
myListener.onLoadInit = function(thisMc:MovieClip) {
thisMc._height = 600;
thisMc._width = 900;
thisMc._x = 50;
thisMc._y = 30;
};
movLoad.addListener(myListener);
movLoad.loadClip("folder/flashpaper_converted_pdf.swf.swf",screen_01);
You can modify the size of the loader using scaleX and scaleY properties.
Keep them equals so the swf isn't stretched.
You may also want to listen to the COMPLETE event to do such a thing :
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onComplete(e:Event)
{
var loader:Loader = e.currentTarget.loader;
loader.scaleX = loader.scaleY = 2; //Double the size of the loaded swf
}
I am embedding an swf file that has some children on its timeline. Like this:
[Embed(source="assets/skyscraper200x600.swf")]
private var Skyscraper :Class;
All children in the swf have an instance name, I double checked that when creating the swf in Flash CS5.
I am trying to access those children by name like this:
_bg = MovieClip(new Skyscraper());
_pig = MovieClip(_bg.getChildByName("chara_pig"));
_arrow = MovieClip(_bg.getChildByName("arrow_banner"));
However, both _pig and _arrow end up being null.
What's even stranger is that when I look at the Skyscraper object in the debugger, it shows a rather strange class name and a Loader as its only child (which in turn has no children). What's up with this?
.
I can access them like above if I do not embed the swf, but load it with a Loader. But I cannot do it in this case. I need to embed the swf.
So, how can you access children of embedded swfs?
I am not talking about accessing classes in the library of the embedded swf, but the instances on the timeline.
Here is a solution. You can also see the steps who helped me find this solution (describeType is your friend) :
public class Demo extends Sprite {
[Embed(source="test.swf")]
private var Test:Class
public function Demo() {
//first guess is that embed SWF is a MovieClip
var embedSWF:MovieClip = new Test() as MovieClip;
addChild(embedSWF);
//well, emebed SWF is more than just a MovieClip...
trace(describeType(embedSWF));//mx.core::MovieClipLoaderAsset
trace(embedSWF.numChildren);//1
trace(describeType(embedSWF.getChildAt(0)));//flash.display::Loader
var loader:Loader = embedSWF.getChildAt(0) as Loader;
//the content is not already loaded...
trace(loader.content);//null
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, function(){
var swf:MovieClip = loader.content as MovieClip;
var child:MovieClip = swf.getChildByName("$blob") as MovieClip;
//do nasty stuff with your MovieClip !
});
}
}
At the end of this tutorial http://jadendreamer.wordpress.com/2010/12/20/flash-as3-embedding-symbols-from-external-swf-game-tutorial there is an example of how it can be done
One solution is to embed the swf as an octet stream and reconstitute its bytes. However, I seem to remember reading somewhere that if you just set the mimeType to "application/x-shockwave-flash", you get a MovieClip that works as normal.
I am trying to build a portfolio application similar to the used by Whitevoid. I am using Flex 4 and Papervision3D 2. I have everything working except for one issue. When I try to load an external SWF as a material on one of the planes, I can see any native Flex or Flash components in their correct positions, but the papervision objects are not being rendered properly. It looks like the viewport is not being set in the nested swf. I have posted my code for loading the swf below.
private function loadMovie(path:String=""):void
{
loader = new Loader();
request = new URLRequest(path);
loader.contentLoaderInfo.addEventListener(Event.INIT, addMaterial);
loader.load(request);
}
private function addMaterial(e:Event):void
{
movie = new MovieClip();
movie.addChild(e.target.content);
var width:Number = 0;
var height:Number = 0;
width = loader.contentLoaderInfo.width;
height = loader.contentLoaderInfo.height;
//calculate the aspect ratio of the swf
var matAR:Number = width/height;
if (matAR > aspectRatio)
{
plane.scaleY = aspectRatio / matAR;
}
else if (matAR < aspectRatio)
{
plane.scaleX = matAR / aspectRatio;
}
var mat:MovieMaterial = new MovieMaterial(movie, false, true, false, new Rectangle(0, 0, width, height));
mat.interactive = true;
mat.smooth = true;
plane.material = mat;
}
Below I have posted two pictures. The first is a shot of the application running by itself. The second is the application as a MovieMaterial on a Plane. You can see how the button created as a spark object in the mxml stays in the correct position, but papervision sphere (which is rotating) is in the wrong location. Is there something I am missing here?
Man. I haven't seen that site in a while. Still one of the cooler PV projects...
What do you mean by:
I cannot properly see the scene rendered in Papervision
You say you can see the components in their appropriate positions, as in: you have a plane with what looks like the intended file loading up? But I'm guessing that you can't interact with it.
As far as I know, and I've spent a reasonable amount of time trying to make something similar work, the MovieMaterial (which I assume you're using) draws a Bitmap of whatever contents exist in your MovieClip, and if you set it to animated=true, then it will render out a series of bitmaps - equating animation. What it's not doing, is displaying an actual MovieClip (or SWF) on the plane. So you may see your components, but this is how:
MovieMaterial.as line 137
// ______________________________________________________________________ CREATE BITMAP
/**
*
* #param asset
* #return
*/
protected function createBitmapFromSprite( asset:DisplayObject ):BitmapData
{
// Set the new movie reference
movie = asset;
// initialize the bitmap since it's new
initBitmap( movie );
// Draw
drawBitmap();
// Call super.createBitmap to centralize the bitmap specific code.
// Here only MovieClip specific code, all bitmap code (maxUVs, AUTO_MIP_MAP, correctBitmap) in BitmapMaterial.
bitmap = super.createBitmap( bitmap );
return bitmap;
}
Note in the WhiteVoid you never actually interact with a movie until it "lands" = he's very likely swapping in a Movie on top of the bitmap textured plane.
The part that you are interacting with is probably another plane that holds the "button" that simply becomes visible on mouseover.
I think PV1.0 had access to real swfs as a material but this changed in 2.0. Sadly. Hopefully Molehill will.
