I am trying to do something like this:
`ParticleEffect pe = new ParticleEffect();
if(pe.getEmitters().get(0).isComplete())
{
pe.getEmitters().get(0).setImagePath("x4.png");
pe.getEmitters().get(0).start();
}`
but the new image does not load, it still shows previous image as declared in .p file. How do I load a new particle ?
Create a sprite from desired texture and then use ParticleEmitter.setSprite() method. This method doesn't have documentation unfortunately. So see source code: https://github.com/libgdx/libgdx/blob/master/gdx/src/com/badlogic/gdx/graphics/g2d/ParticleEmitter.java#L597

I need the ability to be able to create an image of size 400x400 on the fly in a Windows Phone app, which will have a color of ARGB values that a user selects from a color picker. For instance, the user will click on a HyperlinkButton to take them to a ColorPickerPage and then will select a color, and I will retrieve that value and create the image from it, and display this image back on the MainPage. How might something like this be accomplished one I have retrieved the ARGB value from the user? I have not had luck finding any resources on this particular issue.
EDIT**
I came across http://www.geekchamp.com/forums/windows-phone-development/how-to-correctly-save-uicontrol-with-opacity-to-writeablebitmap which creates a rectangle on the screen and then saves to WriteableBitmap, but how might I skip that step and just save the Rectangle to WriteableBitmap? Note, I only have a single rectangle that I Fill with a custom Color.
You can save any UI element as an image using the code below. Here rect is the name of the rectangle in your XAML. If the rectangle isn't present in the UI then simply create one using C#. I have added the code to create a rectangle using C# and commented it.
public void saveimage(int height, int width, String filename)
{
//Rectangle rect = new Rectangle();
//rect.Height = 40;
//rect.Width = 40;
//rect.Fill = new SolidColorBrush(System.Windows.Media.Colors.Cyan);
var bmp = new WriteableBitmap(width, height);
bmp.Render(rect, null);
bmp.Invalidate();
var isf = IsolatedStorageFile.GetUserStoreForApplication();
if (!isf.FileExists(filename))
{
using (var stream = isf.OpenFile(filename, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.ReadWrite))
{
bmp.SaveJpeg(stream, width, height, 0, 100);
stream.Close();
}
}
}
Did you try using the Drawing Class.
here's the reference from msdn.
These are some samples: System.Drawing and System.Drawing.Imaging alternatives for Windows Phone

Hope it helps!
I cant seem to find a solution, anyways basically im trying to add a new dynamic texture to a 3D model using Away3d engine with flash
var myImage:BitmapData = new BitmapData(256, 256, true,0xFFFFFFFF);
// i cant seem to reference this to my 3D model in the example: Myevent(enter frame):
myModel.material = new TextureMaterial(new BitmapTexture(myImage))
I have tried different things along the above method, i have checked the away3d docs and cant find something similar for my current situation:
Im using the latest Away3d lib, and flash player 11...all my models works and load with there original embedded materialtTextures, im just trying to change them to a bitmap or texture that i have dynamically created
Take a look here:
https://github.com/away3d/away3d-tutorials-fp11/blob/master/tutorials/materials/basic_shading/src/Basic_Shading.as
They use Away3D’s Cast utility class to create BitmapTexture objects and they also add a bunch of different texture maps - hopefully this helps
** EDIT --- This Tutorial Does Work **
Added
public bmt:BtiMapTexture;
....
private function initMaterials():void {
this.bmt = new BitmapTexture(new BitmapData(256,256, true, 0x222277FF));
sphereMaterial = new TextureMaterial(Cast.bitmapTexture(this.bmt));
sphereMaterial.specularMap = Cast.bitmapTexture(this.bmt);
sphereMaterial.lightPicker = lightPicker;
}
And I got a nice blue sphere
My solution is:
var mesh:Mesh = 'the mesh for changing'
for each (var item:SubMesh in mesh.subMeshes) {
item.material = null;
}
mesh.material = new ColorMaterial(0xFF00FF);
Does anyone know of any libraries or tools for importing an SVG file into actionscript on the fly? I need to be able to import an SVG file into flash and convert it to a movieclip or preferably a flat 3d object. The end goal here is to implement a vector file with Augmented reality.
A great library for this can be downloaded here: http://code.google.com/p/as3svgrendererlib/
It is easy to implement and reliable. Note that there are two ways to implement the code. I prefer the following because it gives you more control:
private function loadSVG(url:String):void {
ProcessExecutor.instance.initialize(stage);
ProcessExecutor.instance.percentFrameProcessingTime = 0.9;
loader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.TEXT;
loader.addEventListener(Event.COMPLETE, svgLoaded, false, 0, true);
try {
loader.load(new URLRequest(url));
} catch (error:Error) {
trace(error);
}
}
private function svgLoaded(e:Event):void {
var svgString:String = loader.data as String;
var svgDocument:SVGDocument = new SVGDocument();
svgDocument.parse(svgString);
this.addChild(svgDocument);
}
The other way is shorter and might be the way to go when you only have to load a small SVG or just a few.
public function loadSVG(url:String) {
ProcessExecutor.instance.initialize(stage);
ProcessExecutor.instance.percentFrameProcessingTime = 0.9;
var svgDocument:SVGDocument = new SVGDocument();
svgDocument.load(url);
addChild(svgDocument);
}
Two important notes:
1. I could not seem to be able to capture the width or height of the SVGs and the parent Sprite had a width and height of 0 after loading the SVG. I solved this by making all the SVGs the same size before loading them into AS3. After that I knew the dimensions I used the ScaleX and scaleY to resize the loaded SVGs.
2. The stage has to exist before you can use this code. adding the following code will make sure you won't run into problems:yourDisplayClass.addEventListener(Event.ADDED_TO_STAGE, loadYourSVGs);
Now how you convert this to a flat 3D object depends on your 3D Library. I have worked with Away3D where you can use bitmapmaterial on your Sprite3D. The Sprite3D class would be the object to use. I hope your 3D Library supports the use of MovieClips so that you can add them to your 3D Object. Else you will have to use to extract the bitmapMaterial from the movie clip as i have done in the following example:
public function movieClipToBitmapMaterial(mc:MovieClip):BitmapMaterial {
var bmData:BitmapData = new BitmapData(mc.width, mc.height, true, 0xFFFFFF);
bmData.draw(displayObject);
return new BitmapMaterial(bmData);
}
Your input in the above function will be the movieclip onto wich you have loaded your SVG.
I am not sure of this but I think that by using this function you will loose the ability to scale as much as you like without loosing quality.
I hope my input was of some help!
Good luck
PS: don't forget to add the SWC from the link to your project and to check out the provided examples. Please note as well the excellent comment of shaunhusain on your original question. You might not have to use 3D Library.
Salam,
It is very easy:
Open the "name.svg" file in illustartror.
Save it as "name.ai"
Import it into the stage in flash, that is all.
I'm creating a game where a lot of images are being used in Actionscript / Flex 3 (Flash). Now that I've reached the designer stage, I have to work out a structural way of using embedded images (which have to be manipulated with rotation, color, etc.).
Unfortunately, after investigating a bit, it looks like you have to manually embed images before you can use them. I currently have it setup like this:
Resource.as class file:
package
{
public final class Resource
{
[Embed (source="/assets/ships/1.gif" )]
public static const SHIPS_1:Class;
}
}
So, just for one ship I so for have to:
Put the image in the correct folder with the correct name
Name it in the same way in the Resource.as file
Create the constant with the same name in the Resource.as file
Even though this should all be possible by simply putting the file in a specified folder.
To make things even worse, I still have to call it using:
var test:Bitmap = new Resource.SHIPS_1();
There must be better ways to handle resources when creating very huge applications? Imagine I need thousands of images, this system simply wouldn't fit.
If you need to handle a large number of resources you can follow these 3 steps:
Place them in an uncompressed zip archive
Embed the zip file as binary data:
[Embed(source = 'resources.zip', mimeType = 'application/octet-stream')]
Access the resources using FZip
If you choose a different method that involves loading external files be aware that some flash game websites require the games they host to be contained within a single swf file.
instead of
var test:Bitmap = new Resource.SHIPS_1();
Use
myImage.source = Resource.SHIPS_1;
The embedding is correct. :D the way you use it is wrong :)

This is really what Flash CS4 is for. Your way seems fine to me though - although I wouldn't use all caps for a class name even if it is a constant. Just put your head down and get copy-pasting!
Alternatively you could load the files at runtime.
This is old but since I stumbled across it searching for something different I'll write here for future generations : )
I use a different approach. I create a swf movie with flash professional and import all graphics in it and then mark them all for "Export for ActionScript".
Compile the swf and in your main project embed only the swf and access all the graphics through it...
I find this approach much more organized. Why write the whole resources class when you can make it by importing files right? ;)
I just watched this great tutorial on the Starling framework:
http://www.hsharma.com/tutorials/starting-with-starling-ep-3-sprite-sheets/
It sounds like spritesheets are exactly what you're looking for:
You bundle all your individual textures into one big texture that is called spritesheet and create an xml file that contains information where the textures are within the spritesheet. In order to do that you can use this tool:
http://www.codeandweb.com/texturepacker
I'm not sure if you can use it for commercial projects and the amount of textures you're speaking of doesn't sound like you're doing this just as a hobby, so you might want to check the license. There's a pro version available, too.
Texturepacker creates two files: spritesheet.png and spritesheet.xml. You just copy them into your project.
Then you add this code to one of your classes.
private static var gameTextureAtlas:TextureAtlas;
[Embed(source="../media/graphics/mySpriteSheet.png")]
public static const AtlasTextureGame:Class;
[Embed(source="../media/graphics/mySpritesheet.xml", mimeType="application/octet-stream")]
public static const AtlasXmlGame:Class;
public static function getAtlas():TextureAtlas
{
if(gameTextureAtlas==null)
{
var texture:Texture=getTexture("AtlasTextureGame");
var xml:XML=XML(new AtlasXmlGame());
gameTextureAtlas=new TextureAtlas(texture,xml);
}
return gameTextureAtlas;
}
Now you can access all the textures of the spritesheet by calling
YourClass.getAtlas().getTexture("name");
It's simply awesome. When you're using texturepacker the filename of each of the sprites you bundled into the spritesheet becomes its texturename.
This is probably too late to help you, but I hope that future visitors can profit from this elegant solution.
I would like to emphasize that this answer is basically an excerpt from sharma's tutorial. I even felt free to reproduce the code he used in his screencast. All the credit goes to him
It depends how big your individual images are but you could put them all in one image like a spritesheet. If you want to draw a particular ship use the correct xy offset in the image for that ship and use copyPixels to draw it to your bitmap.
package
{
public final class Resource
{
[Embed (source="/assets/ships/1.gif" )]
public static const SHIPS_1:Class;
}
}
[Embed (source="/assets/ships/1.gif" )]
public static const SHIPS_1:Class;
I like to do my Library classes like this.
I took GSkinners code for the singleton: http://gskinner.com/blog/archives/2006/07/as3_singletons.html
package
{
import flash.display.Bitmap;
import flash.display.BitmapData;
public class Lib
{
/*
Make this an Singleton, so you only load all the images only Once
*/
private static var instance:Lib;
public static function getInstance():Lib {
if (instance == null) {
instance = new Lib(new SingletonBlocker());
}
return instance;
}
public function Lib(p_key:SingletonBlocker):void {
// this shouldn't be necessary unless they fake out the compiler:
if (p_key == null) {
throw new Error("Error: Instantiation failed: Use Singleton.getInstance() instead of new.");
}
}
/*
The actual embedding
*/
[Embed(source="assets/images/someImage.png")]
private var ImageClass:Class;
private var _imageClass:Bitmap = new ImageClass() as Bitmap;
[Embed(source="assets/images/someOtherImage.png")]
private var OtherImageClass:Class;
private var _otherImageClass:Bitmap = new ImageClass() as Bitmap;
public function get imgClass():Bitmap{
return _imageClass;
}
public function get imgClassData():BitmapData{
return _imageClass.BitmapData;
}
public function get otherImageClass():Bitmap{
return _otherImageClass;
}
public function get otherImageClassData():BitmapData{
return _otherImageClass.BitmapData;
}
}
}
internal class SingletonBlocker {}
[Embed (source="/assets/images/123.png" )]
public static const className:Class;
Good idea, lhk
That is nice solution like Source-Engine with vtf and vmt
vtf = image
vmt = script ( like xml or javascript )
Good i would like to suggest for TexturePacker, TexturePath or TextureTarget :P
Thanky ou for tip.
For example:
mytexture.js:
xml or javascript:
function mytexture(){ basedir = "/assets/mytexture.png", normalmap =
"/assets/mytexture_bump.png", normalcube ) [ 1, 1, 1 ] };
I don't think because default texture gets error somewhere mytexture.png doesn't exists than it happens again :)
[Embed(source="../assets/editors/error_texture.png")] public static
const ERROR_TEX:Class; ...
How do i know because Actionscript 3 should "read" to javascript like jsBirdge or ExternalInterface.call();
Is it possible?
How to assign bytearray value to panel background image. If anybody have idea or experiance plz help me to overcome the problem. BRIEF EXP:
I have panel control and want to load image getting from webservice as a backgroundimage. So i used setstyle() but its not accepting that image. so how to add that image into my panel background image.Plz tel me your ideas here.
In Flex 3 or higher, you just need to do:
yourImage.source = yourByteArray;
regards!
uhm, well i presume, since it is an image, you have it in a BitmapData, let's say "myBmp" ...
then use the following to extract all the data from BitmapData:
var bytes:ByteArray = myBmp.getPixels(myBmp.rect);
and the following to write:
myBmp.setPixels(myBmp.rect, bytes);
note that only the raw 32 bit pixel data is stored in the ByteArray, without compression, nor the dimensions of the original image.
for compression, you should refer to the corelib, as ozke said ...
For AS3 you can use adobe corelib. Check this tutorial...
http://ntt.cc/2009/01/09/as3corelib-tutorialhow-to-use-jpegencoder-and-pngencoder-class-in-flex.html
I used a flash.display.Loader() to load an image in an array. It has a Complete event that is fired after the image has been loaded. I then draw the image on to a Bitmap which I set to the data of a Image that could be placed in a panel. Hope you can make since of this good luck.
public static function updateImage(img:Image, matrix:Matrix,
pageDTO:PageDTO, bitmapData:BitmapData):void {
var loader:flash.display.Loader = new flash.display.Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, function (e:Event) : void {
bitmapData.draw(loader.content, matrix);
pageViewer.data = new Bitmap(bitmapData);
});
loader.loadBytes(pageDTO.thumbnail);
}
<mx:Panel>
<mx:Image id="pageViewer"/>
</mx:Panel>
Using adobe's JPGEncoder (com.adobe.images.JPGEncoder) class and ByteArray is pretty much all you need. Converting image to byte array (assuming CAPS are variables you'd need to fill in):
// -- first draw (copy) the image's bitmap data
var image:DisplayObject = YOUR_IMAGE;
var src:BitmapData = new BitmapData(image.width, image.height);
src.draw(image);
// -- encode the jpg
var quality:int = 75;
var jpg:JPGEncoder = new JPGEncoder(quality);
var byteArray:ByteArray = jpg.encode(src);
I had the same problem. As a workaround I created sub Canvas nested inside a main Canvas and added an Image to the main Canvas behind the sub Canvas. Anything drawn on the sub Canvas will appear on top of the Image.
Just load it into a Loader instance using the loadBytes function.
var ldr:Loader = new Loader();
ldr.loadBytes(myByteArray);
addChild(ldr);
