How can i put d3dxsprite into object space?
D3DXSPRITE_OBJECTSPACE?
and i could need a example.
Not 100% clear on what you are asking here. Normally object space refers to the space a 3D model is created in and is normally centred on 0,0,0. A sprite is a 2D image only and hence has no such thing. Probably I have misunderstood the question?
not sure what your trying to do but this may help you understand
sprite->SetWorldViewLH(world, view);
sprite->Begin(D3DXSPRITE_OBJECTSPACE | D3DXSPRITE_BILLBOARD | D3DXSPRITE_ALPHABLEND | D3DXSPRITE_SORT_DEPTH_BACKTOFRONT);
sprite->Draw(texture, NULL, &D3DXVECTOR3(pos->x+w, pos->y+h, 0.0f), pos, D3DCOLOR_RGBA(255, 255, 255, 255));
sprite->End();
sprite->SetWorldViewLH(world, view);
sprite->Begin(D3DXSPRITE_OBJECTSPACE | D3DXSPRITE_BILLBOARD | D3DXSPRITE_ALPHABLEND | D3DXSPRITE_SORT_DEPTH_BACKTOFRONT);
sprite->Draw(texture, NULL, &D3DXVECTOR3(pos->x+w, pos->y+h, 0.0f), pos, D3DCOLOR_RGBA(255, 255, 255, 255));
sprite->End();

Can i "move" the sprite in 3D space? or use buffers?
Sprites use an ortho projection and work on the screen space. To get a perpective effect when moving the "sprite" in Z direction, you can use PointSprites or a texture mapped on a 3D plane (two triangles).
I believe that you're looking for:
I haven't tried this code, but I believe that is how it is done (I read a tutorial about 2 months ago.)
Hope that helps!
Edit:
You might need to call Sprite->SetWorldViewLH() in there somewhere, I don't know (I've just begun using 3D graphics.)
Sprite->Begin(D3DXSPRITE_OBJECTSPACE);/*D3DXSPRITE_OBJECTSPACE:The world, view, and projection transforms are not modified. The transforms currently set to the device are used to transform the sprites when the batched sprites are drawn (when ID3DXSprite::Flush or ID3DXSprite::End is called). If this flag is not specified, then world, view, and projection transforms are modified so that sprites are drawn in screen-space coordinates.*/D3DXMATRIX SRTMatrix;// Scale here// Rotate here// Translate hereSprite->SetTransform(&SRTMatrix);Sprite->Draw(pTexture, &Rect, &Center, &Position);I haven't tried this code, but I believe that is how it is done (I read a tutorial about 2 months ago.)
Hope that helps!

Programmer16, That what i'm looking for!
Think you.
What tutorial did you readed.
But i'm not sure how to setup the matrix?

I didn't read a tutorial I look at the documents and figured it out. I knew that transform(ation) is manipulation of 3D objects and I knew that they had to be in object space.
