I want to move the paddles in my game. int move_paddle = 0; // this is the main message handler for the program LRESULT CALLBACK WindowProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { switch (message) { case WM_DESTROY: { PostQuitMessage(0); return 0; } case WM_KEYDOWN: { if (wParam == VK_UP) { move_paddle--; return 0; } if (wParam == VK_DOWN) { move_paddle++; return 0; } break; } break; } return DefWindowProc(hWnd, message, wParam, lParam); } void init_graphics(void) { // create the vertices using the CUSTOMVERTEX struct CUSTOMVERTEX vertices[] = { { 775.0f, 250.0f + move_paddle, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 255, 0), }, { 800.0f, 250.0f + move_paddle, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 255, 0), }, { 775.0f, 350.0f + move_paddle, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 255, 0), }, { 800.0f, 250.0f + move_paddle, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 255, 0), }, { 800.0f, 350.0f + move_paddle, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 255, 0), }, { 775.0f, 350.0f + move_paddle, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 255, 0), }, { 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), }, { 395.0f, 295.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, { 405.0f, 295.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, { 395.0f, 305.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, { 405.0f, 295.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, { 405.0f, 305.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, { 395.0f, 305.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, };
