For some reason, most Scene2D (= in the tests package) don't work which use the stage, because it is null. MaskTest works for example, it doesn't access the stage object anywhere.

Problem: when using sprite.spritesheet.playAnimation("run"), sprite.width/height is not updated immediately.

Possible Solution 1:
+Sprite2d.as:
public function updateSize():void {
if(spriteSheet) {
_width = spriteSheet.spriteWidth;
_height = spriteSheet.spriteHeight;
}
}

Possible Solution 2:
+Sprite2d.as:
public function playAnimation(value:String ..... ):void {
if(spriteSheet) {
spriteSheet.playAnimation(value ...... );
_width = spriteSheet.spriteWidth;
_height = spriteSheet.spriteHeight;
}
}

If I start Main.as test with BlurTest

activeSceneIdx = 25;

I see this http://pix.am/oHMh/

PostProcessingTest and SideScrollerTest throw this error:

RangeError: Error #1125: Index 2147483647 lies outside valid bounds of 35

All other tests work now, thank you :)

Lately a major performance bottleneck has been identified on older devices, the confirmed ones I know of are: iPhone 4, iPad 1, iPod Touch 4, Nexus One and Galaxy Nexus.

Starling and Genome2D have both optimized for it, and from what they tell me:

The issue relates to these devices having limited fragment shaders when using any type of blending. For objects that have a value of 1.0, if the alpha operation is omitted from the shader, you can yield up to a 3x improvement in performance.

The one drawback is that batching needs to be separated now, instead of one batch to need to split them into alpha and non-alpha, but this only impacts higher end of devices, and the impact is generally minimal.

You can see my latest benchmarks here where I compare all the devices, you can see that Starling is outperforming ND2D 2:1 in most tests, except the iPad 2 where this seems to be a non-issue.

The dynamic texture plugin needs to subclass ASpriteSheetBase, but a bunch of the properties are marked as internal.

If you'll switch to protected instead, it will resolve the issue.

ASpriteSheetBase @ Line 41:
protected var frames:Vector. = new Vector.();
protected var offsets:Vector. = new Vector.();
protected var sourceSizes:Vector. = new Vector.();
protected var sourceColorRects:Vector. = new Vector.();
protected var frameNameToIndex:Dictionary = new Dictionary();
protected var uvRects:Vector.;
protected var spritesPackedWithoutSpace:Boolean;

What about to add geometry class for more simple working with faces, hit test collection, etc?

I created some example https://github.com/profelis/nd2d/blob/experimental/src/de/nulldesign/nd2d/geom/Geometry.as

pro geometry

• simple realign geometry from center to top-left
• simple work with faces, create complex grids
• clone complex geometry (reuse)

contra

• geometry contains in vertexBuffer materials data (can't reuse geometry without clone)

I think that would be better to have some API for adding custom parsers for TextureAtlas, since some people can't use Zwoptex (no Mac) or TexturePacker (too costly). Something like this:
TextureAtlas.registerParser(name:String, parser:ATextureAtlasParser):void;

This could be a pull request, but I thought it was simple enough to just post here.

I found this useful when creating one giant TextureAtlas to hold all my various graphics:

ASpriteSheetBase.as @ Line 185
public function setFrameByAnimationName(name:String):void {
if(animationMap[name]){
frame = animationMap[name].frames[0];
}
}

This way I can easily gotoAndStop on single frame animation.

Workaround would be something like:
s.spriteSheet.playAnimation("cloud");
s.spriteSheet.stopCurrentAnimation();

When adding a SpriteCloud to another SpriteCloud, only the first sprite shows up of the child.

i.e.

loop 4
{
loop 20
{
loop 30
{
sprite2d = new sprite2d
spriteCloudChild.addChild(sprite2d);
}
}
masterSpriteCloud.addChild(spriteCloudChild);
}
scene2d.addChild(masterSpriteCloud)

only the first sprite2d of each spriteCloudChild shows up.

Here's what I did:
when some.bitmapData is used for the first time
myCloud = new Sprite2DCloud(100, some.bitmapData);
myCloud.addChild(new Sprite2D());

whenever some.bitmapData is used again then Ijust
myCloud.addChild(new Sprite2D());

the result is that only first 2 children of myCloud are drawn, and I can't figure out why.

Hi,

I was working with localToGlobal on a project and found I was getting odd results when the camera moved. Adding camera.x/y to the localToGlobal output Point fixed my issue.

I have a fork of the project, but didn't think it was worth making a pull request for this, and I've been modifying other things in there that you probably don't want in the framework... feel free to merge it (or ask me to make a pull request) if you want though :)

Have a look at localToGlobal in Node2D.as in this commit, specifically, where the output Point is created/set:
mikedotalmond@a1f936c

Also, the equivalent fix in (my modified version of) globalToLocal:
mikedotalmond@d8af9cd

Thanks for making a fun library :)

The current implementation of MouseEvent.click responds to the whole area of the bitmap of the scene. In contrast, the old flash2D clicking only response to non-transparent area whitch was quite handy. Is nd2d going to use the old way later or suggesting some new skills?
The imaginary scenario would be some monsters crowding in an isometric view. The player now wants to shoot one of them, by clicking on its body part that is not covered by another monster.

Add internal namespace (nd2d for example) (Away3D - arcane, Minko - minko, minko_animation ...)

small demo https://github.com/profelis/nd2d/blob/experimental/src/de/nulldesign/nd2d/materials/texture/Texture2D.as#L62

Core classes can use variables with namespace (use namespace nd2d), others call public getters.

It would be nice to be able to use TweenMax along with Nd2d. TweenMax provides a lot of well tested 2d features. It doesn't have to be some api called 'useTweenMaxHere' but some general api and an instruction of how to use them together is good enough.

In my test, SpriteCloud is not rendering any faster than then normal Sprite2D's, when I'm using SpriteSheet. Same issue exists with SpriteBatch2D.

Using a single spritesheet, shared across all animations, caps out at about 380 @ 60fps, regardless of rendering technique.

Code for adding Sprite2D's is something like this:
texture = Texture2D.textureFromBitmapData(moleData);
spriteSheet = new SpriteSheet(texture.bitmapWidth, texture.bitmapHeight, frameWidth, frameHeight, 60);
spriteSheet.addAnimation("dig", [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19], true);

for(var i:int = particleList.length; i < numParticles; i++){
var s:Sprite2D = new Sprite2D(texture);
s.spriteSheet = spriteSheet;
s.spriteSheet.playAnimation("dig");
scene.addChild(s);
}

Code for adding with cloud, is like this:

texture = Texture2D.textureFromBitmapData(moleData);
cloud = new Sprite2DCloud(500, moleData);
spriteSheet = new SpriteSheet(texture.bitmapWidth, texture.bitmapHeight, frameWidth, frameHeight, 60);
spriteSheet.addAnimation("dig", [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19], true);
scene.addChild(cloud);

for(var i:int = particleList.length; i < numParticles; i++){
var s:Sprite2D = new Sprite2D();
s.spriteSheet = spriteSheet;
s.spriteSheet.playAnimation("dig");
cloud.addChild(s);
}

Obviously all frames are not in sync, and can't all be batched, but I'd assume the framework would be batching identical frames within the cloud, 20 batches for a 20 frame animation...

On 0.97.swf clicking is only effective on Rectangle(0,0,512,384) area. Is it a bug or I'm missing some config?

Sprite2DBatchMaterial.as -> processAndRenderNodes()
I've got an error at this line:
clipSpaceMatrix.appendScale(child.spriteSheet.spriteWidth >> 1, child.spriteSheet.spriteHeight >> 1, 1.0)
I've changed it to this:
clipSpaceMatrix.appendScale(child.spriteSheet.spriteWidth * 0.5, child.spriteSheet.spriteHeight * 0.5, 1.0)
And all works fine now.

Hi there! Great engine, thanks for your hard work.
I've found a bug. Pivots can't be used with sprites in the Sprite2DCloud.
Sprite always rotates around 0, 0 point. Regardless of the value of it's pivot.

To repeat this bug open "MassiveSpriteCloudTest.as" and find this function:
private function addSpritesClick(event:MouseEvent = null):void {
var s:Sprite2D;
for(var i:int = 0; i < 100; i++) {
s = new Sprite2D();
s.x = Math.round(Math.random() * 1000);
s.y = Math.round(Math.random() * 1000);
s.vx = (Math.random() - Math.random()) * 3;
s.vy = (Math.random() - Math.random()) * 3;
s.pivot = new Point(100, 100); <-------- And add this
...

Uncomment "s.rotation += 10;" in the "step" function.

P.S:
Is it possible to add _z property to the Node2D for a quick z-sorting? Using Add/RemoveChild in 3d engine is a bit strange...

When writing a speedtest I noticed that the first screenrender would stay onscreen the whole time. Somehow the first render doesn't get cleared properly. You can see this in action here:

http://www.todorus.com/gunrun/speedtests/nd2d-bug/

When I don't add them at the first frame everything seems to work fine.

Hello, I am curious as to why there is no batching of Sprite2ds with the same texture at consecutive levels in the global display hierarchy. This is done in Starling.

Didn't realize there is a forum. This is probably more appropriate for that.

Add internal namespace (nd2d for example) (Away3D - arcane, Minko - minko, minko_animation ...)

small demo https://github.com/profelis/nd2d/blob/experimental/src/de/nulldesign/nd2d/materials/texture/Texture2D.as#L62

I tried alpha on spriteclouds, works, sprite2d work, font2d alpha does not work.

Please add pivot3d:Vecor3D

at present i got 7/60fps if -debug=true via AIR/FP beta6
i think MassiveSpritesTest is faster before beta6?

I've been trying to use the masking and ran into a couple different issues.

1. The edges of a mask continue out across the entire masked area.
2. A mask at certain sizes shrink, as noted in this comment: http://www.nulldesign.de/2011/09/02/nd2d-stage3d-masks/#comment-35536

Here is a test swf and project to demonstrate these issues:
www.fapfaprevolution.com/tests/nd2dMaskGlitch/ - press space bar to cycle through the masks
www.fapfaprevolution.com/tests/nd2dMaskGlitch/nd2dMaskGlitch_fdproject.zip

in a Scene2D class
var tex:Texture2D = ballTexture;
var ball:Sprite2D = new Sprite2D(tex);
ball.alpha = 0.6;
addChild(ball);

var ballOther:Sprite2D = new Sprite2D(tex);
ballOther.alpha = 0.5;
addChild(ballOther);

ballOther.addChild(ball);

I put a break point at drawNode

here is 3 times drawNode and content.drawTriangle
2 by ball , 1 by ballOther
alpha
0.6 , 0.5 , 0.3

but only two ball on sreen
why ?

ps:
i have test atf texture.
alpha ath work right on Sprite2D;
but has white backgroundColor on Sprite2DBatch;

not always , use different asset
i don't find out agal and blendmode has different place.

I find it is very slow to setTexture each frame to make an animation.Because it dispose the old texture very time.

And,I want Sprite2D can play an array of textures or bitmaps.

Screencast
screencast not exact, in fact flickering like one frame visible, next frame not, ...

29 April, Danial talked about this

I tried compiling a few examples of ND2D with the latest Air 3 RC. Everything works fine when I debug on desktop (IOS profile).
Once I package and installed on IOS, the app doesn't seem to work, it stucks on a blank white screen with a black box which is the stat viewer. Is Stage3D or ND2D supported in IOS at this stage?

Thanks

Hi Lars!
Pivots are still a little buggy :)
Just try "MassiveSpriteCloudTest.as" with s.pivot = new Point(0, -15);
(and vx = vy = 0)
While using Sprite2DBatch it is all ok (man rotates around his head). But in Sprite2DCloud it's rotates around bottom point of his legs. In this example it doesn't seem very important. But it ruins all my animations :)

Here is an example, first with Sprite2DBatch:
http://dl.dropbox.com/u/43384235/ok.html

And Sprite2DCloud:
http://dl.dropbox.com/u/43384235/bad.html

to reproduce:

get localToGlobal from Node2d,

set z, rortationX, rortationY or rotationZ to random values,

and get the localToGlobal again - you will get the same point as first one.

Bug 1) depth works a bit different in the engine then in regular actionscript 3. and depth seems to work on sprite2d's but not sprite2d's that are in clouds.

Bug 2) to change depth of a sprite2d (not in cloud) you have to remove it from the scene and re-add it, instead of just scene.addChild(scene.getChildAt(0)) to bring it foremost, you have to say scene.removeChild(0); scene.addChild(sameSprite);

I'm a game developer from Tinime Games who are now using nd2d to develop a new flash game for our client and I want to say thank you so much for the talented work .

Is there a way like cocos2d to push and pop scene in the game world? I think it would be very useful .It would be great if you consider to add this feature in the future version. : )

Hello Lars, it's me again :)
TextureAtlasTest.as:
Replace "batchChild.spriteSheet.playAnimation("blah", i, true); "
with "batchChild.spriteSheet.frame = 0;"
It will not be rendered.

P.S:
And it is so blurry: http://dl.dropbox.com/u/43384235/blurry.jpg

Hopefully I'm not doing something stupid here but setting the alpha property on Sprite2D doesn't seem to do anything. I experimented with SpriteTest from the examples and couldn't see any alpha transparency being rendered.

Add additional mouse capturing strategy. Current implementation not cover all variants of usage (example: custom shape button).

As a workaround, you can use:

1. Alpha channel of texture in Sprite2D class and some custom treshold (not a perfect solution)
2. Add shapeMask field (of type BitmapData) to Node2D and use binary bitmap for handling custom shapes (I vote for this solution)

When using a spritesheet and you play an animation on just one sprite2d, you can no longer set a frame number on any other sprite2d inside the same cloud by using .frame. You have to set animations for all other items.

What I said may not make sense, so I made a demo of the issue. The middle guy is playing an animation, the rest of them have spritesheet.frame =

    private var sc:Sprite2DCloud;
    private var numOfSprites:int = 5;
    public function SpriteAnimTest2() {

        var sheet:SpriteSheet = new SpriteSheet(new spriteTexture().bitmapData, 24, 32, 5);
        sheet.addAnimation("up", [0, 1, 2], true);
        sheet.addAnimation("right", [3, 4, 5], true);
        sheet.addAnimation("down", [6, 7, 8], true);
        sheet.addAnimation("left", [9, 10, 11], true);

        sc = new Sprite2DCloud(numOfSprites,null,sheet);
        addChild(sc);
        addEventListener(Event.ADDED_TO_STAGE,sceneAdded);
        }

    protected function sceneAdded(event:Event):void
    {
        // TODO Auto-generated method stub
        removeEventListener(Event.ADDED_TO_STAGE,sceneAdded);
        for(var i:int = 0; i < numOfSprites; i++)
        {
            var s:Sprite2D = new Sprite2D();
            sc.addChild(s);

            //places in center
            s.y = stage.stageHeight/2;
            s.x = ((i-numOfSprites)*50)+stage.stageWidth/2;

            if(i == int(numOfSprites/2))
                s.spriteSheet.playAnimation("down");
            else
                s.spriteSheet.frame = i;
    }
}
}

}

Thanks!

Hi there.
I'm tring to use nd2d for making a game.
And, I found some bug at Sprite2D.setMaterial method.

If make Sprite2D object first, and then assign Sprite2DMaterial later, like below,
I can't see any rendering image.

var sp:Sprite2D = new Sprite2D();
var sheet:SpriteSheet = new SpriteSheet(imageBitmapData, 100, 100, 5);
sheet.addAnimation('idle',[0,1,2],true);
var mat:Sprite2DMaterial = new Sprite2DMaterial(null, sheet);
sp.setMaterial(mat); // can't see any

So, I added some codes at Sprite2D.seMaterial

this.spriteSheet = material.spriteSheet;
if (material.bitmapData === null) material.bitmapData = this.spriteSheet.bitmapData;

Then, It works~!
I hope this helps.

Thanks for nice api.
