I am trying to build a pong game using dx9. I am able to draw a paddle on the left side of the screen. I want to draw a paddle on the right side of the screen. I am very new at dx9.
void render_frame(void)
{
d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 0, 0), 1.0f, 0);
d3ddev->BeginScene();
// select which vertex format we are using
d3ddev->SetFVF(CUSTOMFVF);
// select the vertex buffer to display
d3ddev->SetStreamSource(0, v_buffer, 0, sizeof(CUSTOMVERTEX));
// copy the vertex buffer to the back buffer
d3ddev->DrawPrimitive(D3DPT_TRIANGLELIST, 0, 2);
d3ddev->EndScene();
d3ddev->Present(NULL, NULL, NULL, NULL);
}
// this is the function that cleans up Direct3D and COM
void cleanD3D(void)
{
v_buffer->Release(); // close and release the vertex buffer
d3ddev->Release(); // close and release the 3D device
d3d->Release(); // close and release Direct3D
}
// this is the function that puts the 3D models into video RAM
void init_graphics(void)
{
// create the vertices using the CUSTOMVERTEX struct
CUSTOMVERTEX vertices[] =
{
{ 0.0f, 250.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), },
{ 25.0f, 250.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), },
{ 0.0f, 350.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), },
{ 25.0f, 250.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), },
{ 25.0f, 350.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), },
{ 0.0f, 350.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), },
};
// create a vertex buffer interface called v_buffer
d3ddev->CreateVertexBuffer(6 * sizeof(CUSTOMVERTEX),
0,
CUSTOMFVF,
D3DPOOL_MANAGED,
&v_buffer,
NULL);
VOID* pVoid; // a void pointer
// lock v_buffer and load the vertices into it
v_buffer->Lock(0, 0, (void**)&pVoid, 0);
memcpy(pVoid, vertices, sizeof(vertices));
v_buffer->Unlock();
}
