@yang: You could set the scaleX to -1 to achieve a mirror effect.

Hi,
I have a spritesheet with 5 direction and I want mirror 3 of them to make 8 direction game.
my question is , how can I mirror it at runtime?

Hi, I've also been working on Nape+ND2D integration and have recently push the project to github... Napoleon Napoleon test page My ND2D fork During development I've also been modifiying and adding to ND2D (in my fork) - including adding Polygon2D for creating / drawing convex polygons in ND2D. It's early days, but I'm pretty happy with how it's coming along, thanks mainly to the solid foundations provided by ND2D! :)

Thanks for your hard work! I hope I’ll release a cool game on it :)

[...] I said, I’ll explain the difference between a Sprite2DCloud and a Sprite2DBatch and here we go. I won’t get into technical details here, but there a basically two different methods for batching data. For those who are interested: ND2D – speeding up the engine. [...]

@lars: Oh nice! I didn’t realize there was a method ‘setRenderToTexture(…)’, I’ll keep that in mind :) Thanks a lot!

To achieve a blur, you could render your whole scene (or parts of the scene) to a native Context3D texture and render a full screen quad with this texture and a blur fragment shader. BitmapData and PixelBender2D is a totally different world and don’t exist in a Stage3D environment.

@lars: Ok I should clarify my question. I just want to understand the whole process of post processing in Stage3D. Do you have to: Render your scene, draw it to a BitmapData, create a new Scene with only one screen Quad (plane object) with your original Scene as the texture, then use a Fragment Shader to blur the scene? Or…
Applying a PixelBender2D Shader to the rendered Scene (as BitmapData) then draw it to the screen Quad?

I’m not sure I understand how you can sample pixels around one given pixel location (unless I’m not thinking “outside the box” enough!)

i’m troubled with the matter about quad batching. i batched 30 quads(120 vc) within one batch, and the quad textures is paint a humanbody that some parts of the pic are 0 alpha.
Before calling draw() this batch, the quads vertex index has been sorted by z axis from far to near. OK, with context3d.setBlendFactors(SOURCE_ALPHA, ONE_MINUS_SOURCE_ALPHA) and context3d,setDepthTest(true, LESS_EQUAL), there shows the rigth depth and alpha blend effect.
Then,after the batch drawed , here i wanna go on to draw a quad( or more) which is with a z-axis value among the z-axis values which R of just mentioned quads batch. i aim to draw a new quad locates among the quads last batched.
The problem is showing, the alpha blend is wrong! :( it didnot approach to my aim. the batched quads blend the background color but not the zero alpha wanted, with z-axis smaller than the z of the one quad .(if i didn’t describe it clearly, i think a mail with pics can do it)
Thus, i wonder that if the quads batch is really easy-using in a RPG game which contains a batch of same-looking monsters and several hero roles running across the batched monsters….

happy new year~looking forward to ur reply

@chamberlainpi: You can’t use the 2D Pixelbender with Stage3D. This would be only possible with the Pixelbender 3D, but I can’t recomment this one, because it’s unfinished an buggy. So you have to code shaders in AGAL and you can do whatever you can think of with them ;)

Hi Lars!!!

Just found your personal blog on the web following some links from adobe…
I have been following some Guy “Der Bauer” (http://www.derbauer.de/) on his 3D work on the web but all the time trying to get the real feeling about what interactivity is all about…. i must say that you realy impressed me with this wonderful example…..just feel sory that i do not have the means to get an ipod and experience it on hand, on the other hand do not as well have any code know how to develop anything like it…….but here is my testimony that you will be in my mind.

Great successes on your carer, is my wish and a happy Christmas season.
