Thanks for your help.  Unfortunately that didn't do the trick.  Here's what I'm basically doing in onDrawFrame, hopefully it's enough for some insight;

               sprite.build(false); //called much earlier outside of onDrawFrame

               //inside onDrawFrame
      quadUVs = animationTexture.getCurrentQuadUVs(); //my own class, the UVs come back correct every frame
      tex1 = new TextureInfo(
                TextureManager.getInstance().getTextureID( "spritetex" ),
                quadUVs.u1, quadUVs.v1, quadUVs.u2, quadUVs.v2,
                quadUVs.u4, quadUVs.v4 );
        tex2 = new TextureInfo(
                TextureManager.getInstance().getTextureID( "spritetex" ),
                quadUVs.u2, quadUVs.v2, quadUVs.u3, quadUVs.v3,
                quadUVs.u4, quadUVs.v4 );
        sprite.getPolygonManager().setPolygonTexture( polyIdOffset,
                                                    tex1 );
      sprite.getPolygonManager().setPolygonTexture( polyIdOffset + 1,
                                                    tex2 );

      sprite.touch();

...I only ever see the first frame, unless I forcibly skip it, then I see the second.  I know the screen is updating as I can see a framerate blit I have going.

Hi All,

I'm having a hard time figuring out how to do animated sprites efficiently (and easily!).  Is there a single best way?  Let's say I need hundreds of them animating on the screen at once.  Swapping textures around certainly doesn't seem the best way,...can I change UV coordinates on the fly?

Thanks!

Thanks, I did finally get a touch point to project a ray into the world, but I can't pick an object.

Using calcMinDistanceAndObject3D always returns empty, even when I can see my ray hitting an object.

Object[] result = getWorld().calcMinDistanceAndObject3D(camera.getPosition(), ray, 10000F);

result[0] always has a float
result[1] is always null

Any ideas?

I've discovered my graphic was also messed up, and switched to png with no problems.

I've started making dialogs with overlays.  Is there something I'm missing about using transparency with overlays?  I can't seem to make it happen in hw/sw modes.  Transparent textures in 3Dobjects do work fine...

Basically, I'm just creating the texture with something like;

Texture texture = new Texture(image,useAlpha);

and I've tried adding textureInfo to the effect of;

ti.add(textureID,TextureInfo.MODE_ADD);

For the moment I'm manually tracking overlay depth(z-order) while testing, and everything is 1f apart.  (I will make a depthmananger soon...)

My efforts so far give me overlays, but they all seem to jiggle on the screen x-axis abit, and transparency isn't working.

Tips appreciated!

Thanks!   What do you mean when you say overlay?  Do you mean creating and displaying an image and then detecting mouse clicks on it in specific areas?
