Hey guys, new to the forum. Anyway, I have written a program to animate a sprite with transpatency support with the help of a book. But see, I keep getting these two erros: 'D3DXSPRITE_ALPHABLEND' : undeclared identifier 'Draw' : function does not take 5 parameters In fact, I loaded and ran the example program in the book as it is, and I still get these same errors. How can I fix this thing? Heres the chunk of code does the drawing: if (d3ddev->BeginScene()) { d3ddev->StretchRect(back, NULL, backbuffer, NULL, D3DTEXF_NONE); sprite_handler->Begin(D3DXSPRITE_ALPHABLEND); D3DXVECTOR3 position((float)kitty.x, (float)kitty.y, 0); sprite_handler->Draw( kitty_image[kitty.curframe], NULL, NULL, &position, D3DCOLOR_XRGB(255,255,255)); sprite_handler->End(); d3ddev->EndScene(); }
