what am i doing wrong in this?Code:unsigned int uiStride; bool bTex = false, bCham = false; LPDIRECT3DTEXTURE9 pTexture[2]; const BYTE bRed[60] = { 0x42, 0x4D, 0x3C, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x36, 0x00, 0x00, 0x00, 0x28, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x01,0x00, 0x00, 0x00, 0x01, 0x00, 0x20, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x12, 0x0B, 0x00, 0x00, 0x12, 0x0B, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xFF, 0x00, 0x00, 0x01 }; const BYTE bYellow[60] = { 0x42, 0x4D, 0x3C, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x36, 0x00, 0x00, 0x00, 0x28, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x01, 0x00, 0x20, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x12, 0x0B, 0x00, 0x00, 0x12, 0x0B, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xFF, 0xFF, 0x00, 0x00, 0x01 }; HRESULT APIENTRY pIDirect3DDevice9::BeginScene() { if(bTex == false) { D3DXCreateTextureFromFileInMemory(pDevice, (LPCVOID)&bRed, sizeof(bRed), &pTexture[0]); D3DXCreateTextureFromFileInMemory(pDevice, (LPCVOID)&bYellow, sizeof(bYellow), &pTexture[1]); bTex = true; } return pDevice->BeginScene(); } HRESULT APIENTRY pIDirect3DDevice9::DrawIndexedPrimitive(D3DPRIMITIVETYPE PrimitiveType, INT BaseVertexIndex, UINT MinVertexIndex, UINT NumVertices, UINT startIndex, UINT primCount) { if(GetAsyncKeyState(VK_F1)&1) bCham = !bCham; if(bCham == true && uiStride == 52) { pDevice->SetRenderState(D3DRS_ZENABLE, false); pDevice->SetTexture(0, pTexture[0]); pDevice->DrawIndexedPrimitive(PrimitiveType, BaseVertexIndex, MinVertexIndex, NumVertices, startIndex, primCount); pDevice->SetRenderState(D3DRS_ZENABLE, true); pDevice->SetTexture(0, pTexture[1]); return pDevice->DrawIndexedPrimitive(PrimitiveType, BaseVertexIndex, MinVertexIndex, NumVertices, startIndex, primCount); } return pDevice->DrawIndexedPrimitive(PrimitiveType, BaseVertexIndex, MinVertexIndex, NumVertices, startIndex, primCount); } HRESULT APIENTRY pIDirect3DDevice9::SetStreamSource(UINT StreamNumber, IDirect3DVertexBuffer9* pStreamData, UINT OffsetInBytes, UINT Stride) { if(StreamNumber == 0) uiStride = Stride; return pDevice->SetStreamSource(StreamNumber, pStreamData, OffsetInBytes, Stride); }
