Srpites ?

[Coder]

Hi!
Ich versuche schon seit ein paar Tagen sprites anzeigen zu lassen.
Jedoch geht das immer in die Hose. Gibt es ein Beispiel ? Also KEINE Partikelsysteme oder der gleichen. Ich will erstmal ein Sprite auf der Poition 0.0.0 Rendern.. Gibt es sowas ?

Problem: ich seh nichts!

Coder der nicht geht:

IDirect3DVertexBuffer9 *pPSVB;
IDirect3DTexture9 *pTexture;

struct POINTVERTEX
{
   D3DVECTOR v;
   D3DCOLOR color;
};
#define D3DFVF_POINTVERTEX (D3DFVF_XYZ|D3DFVF_DIFFUSE)

POINTVERTEX vPVertices[1];

void InitPS()
{

    vPVertices[0].v.x = 0.0f;
    vPVertices[0].v.y = 0.0f;
    vPVertices[0].v.z = 0.0f;
    vPVertices[0].color = D3DCOLOR_XRGB(255, 0, 0 );

    // Create the vertex buffer.
    if( FAILED( pGraphics->GetDevice()->CreateVertexBuffer( 1*sizeof(POINTVERTEX),
                                                  D3DUSAGE_WRITEONLY | D3DUSAGE_POINTS, D3DFVF_POINTVERTEX,
                                                  D3DPOOL_DEFAULT, &pPSVB, NULL ) ) )
    {

    }
    // Fill the vertex buffer.
    VOID* pVertices;
    if( FAILED( pPSVB->Lock( 0, sizeof(vPVertices), (void**)&pVertices, 0 ) ) )
    {
    }
    memcpy( pVertices, vPVertices, sizeof(vPVertices) );
    pPSVB->Unlock();

    D3DXCreateTextureFromFile( pGraphics->GetDevice(), "point.jpg" , &pTexture);
}

void ReleasePS()
{
    pPSVB->Release();
    pTexture->Release();
}

inline DWORD FtoDW( float f )
{
   return *((DWORD*)&f);
};

void RenderPS()
{
   pGraphics->GetDevice()->SetRenderState( D3DRS_POINTSPRITEENABLE, true    );
   pGraphics->GetDevice()->SetRenderState( D3DRS_POINTSCALEENABLE, true );

   // set states
   //pGraphics->GetDevice()->SetTexture( 0, pTexture);
   pGraphics->GetDevice()->SetRenderState( D3DRS_LIGHTING, false );
   pGraphics->GetDevice()->SetRenderState( D3DRS_ZWRITEENABLE, false );
   pGraphics->GetDevice()->SetRenderState( D3DRS_ALPHABLENDENABLE, true );

   pGraphics->GetDevice()->SetRenderState( D3DRS_SRCBLEND, D3DBLEND_INVSRCCOLOR);
   pGraphics->GetDevice()->SetRenderState( D3DRS_DESTBLEND, D3DBLEND_INVSRCCOLOR);

  pGraphics->GetDevice()->SetRenderState( D3DRS_POINTSIZE_MIN, FtoDW(0.00f) );
  pGraphics->GetDevice()->SetRenderState( D3DRS_POINTSCALE_A, FtoDW(0.00f) );
  pGraphics->GetDevice()->SetRenderState( D3DRS_POINTSCALE_B, FtoDW(0.00f) );
  pGraphics->GetDevice()->SetRenderState( D3DRS_POINTSCALE_C, FtoDW(1.00f) );

   pGraphics->GetDevice()->SetRenderState( D3DRS_POINTSIZE, FtoDW(1.0f) );

   pGraphics->GetDevice()->SetStreamSource( 0, pPSVB, 0, sizeof( POINTVERTEX) );
   pGraphics->GetDevice()->SetFVF( D3DFVF_POINTVERTEX );

   /*pPSVB->Lock(0 ,1 * sizeof (POINTVERTEX),(BYTE **) &vPVertices,0);
   pPSVB->Unlock();*/

   //pGraphics->GetDevice()->SetTransform(D3DTS_WORLD, &m_matWelt);
   pGraphics->GetDevice()->DrawPrimitive( D3DPT_POINTLIST, 0, 1 );

  // deset states
    pGraphics->GetDevice()->SetRenderState( D3DRS_ZWRITEENABLE, true );
    pGraphics->GetDevice()->SetRenderState( D3DRS_ALPHABLENDENABLE, false );
   pGraphics->GetDevice()->SetRenderState( D3DRS_POINTSPRITEENABLE, false    );
   pGraphics->GetDevice()->SetRenderState( D3DRS_POINTSCALEENABLE, false );
   pGraphics->GetDevice()->SetRenderState( D3DRS_LIGHTING, false );

}

Hi!
Sry, Admin! Sollte in die Grafik.programmierung !!
Kann das jemand bitte dorthin stellen ?
