I am missing something and need help. I've defined 12 vertices and put them in a vertex buffer. This is the FVF format:
#define D3DFVF_PLAYINGCARD_FACE_VERTEX (D3DFVF_XYZ | D3DFVF_DIFFUSE | D3DFVF_TEX1)
struct PLAYINGCARD_FACE_VERTEX
{
D3DXVECTOR3 position;
D3DXCOLOR color;
float u, v;
};
These are the 12 vertices. They share a large texture that has 4 rows of 14 different cards which is where the cardTexWidth, cardTexHeight stuff comes in.
Top Left Corner(clockwise) - Bottom Left Corner 0,1,2,3:
Top Left Corner(clockwise) - Bottom Left Corner 4,5,6,7:
//Playing Card Vertices For Face Of Card
const float cardWidth = (float)m_width/2.0f;
const float cardHeight = (float)m_height/2.0f;
const float cardTexWidth = 1.0f/14.0f;
const float cardTexHeight = 1.0f/4.0f;
float u = (float)m_value/14.0f;
float v = (float)m_suit/4.0f;
PLAYINGCARD_FACE_VERTEX arrCardFaces[] =
{
//Face #1
{D3DXVECTOR3(-cardWidth, cardHeight, -2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), u, v}, //Vertex 0
{D3DXVECTOR3(cardWidth, cardHeight, -2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), u + cardTexWidth, v}, //Vertex 1
{D3DXVECTOR3(cardWidth, -cardHeight, -2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), u + cardTexWidth, v + cardTexHeight}, //Vertex 2
{D3DXVECTOR3(-cardWidth, cardHeight, -2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), u, v}, //Vertex 0
{D3DXVECTOR3(cardWidth, -cardHeight, -2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), u + cardTexWidth, v + cardTexHeight}, //Vertex 2
{D3DXVECTOR3(-cardWidth, -cardHeight, -2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), u, v + cardTexHeight}, //Vertex 3
//Face #2
{D3DXVECTOR3(cardWidth, -cardHeight, +2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), cardTexWidth, cardTexHeight}, //Vertex 6
{D3DXVECTOR3(cardWidth, cardHeight, +2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), cardTexWidth, 0.0f}, //Vertex 5
{D3DXVECTOR3(-cardWidth, cardHeight, +2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), 0.0f, 0.0f}, //Vertex 4
{D3DXVECTOR3(-cardWidth, -cardHeight, +2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), 0.0f, cardTexHeight}, //Vertex 7
{D3DXVECTOR3(cardWidth, -cardHeight, +2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), cardTexWidth, cardTexHeight}, //Vertex 6
{D3DXVECTOR3(-cardWidth, cardHeight, +2.0f), D3DXCOLOR(1.0f, 1.0f, 1.0f, 1.0f), 0.0f, 0.0f} //Vertex 4
};
Whenever I render the faces I don't see the texture. Instead I see a solid color (which is not white). If I choose, as the D3DTSS_COLOROP, D3DTOP_SELECTARG1 then the color is blue and if I choose D3DTOP_SELCTARG2 then the color is red.
I have lighting off, z-buffer and target clearing to white, zenable on, and max/min filter to linear. Any help you could give would be most appreciated.
Thanks,
