Pong and DirectX9

I am trying to move a pong paddle but I can't seem to get it to move. float x = 0.0f, y = 0.0f; // 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) { y--; } if (wParam == VK_DOWN) { y++; } } break; } return DefWindowProc(hWnd, message, wParam, lParam); } void init_graphics(void) { // create the vertices using the CUSTOMVERTEX struct CUSTOMVERTEX vertices[] = { { 0.0f, 250.0f+y, 0.0f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), }, { 25.0f, 250.0f+y, 0.0f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), }, { 0.0f, 350.0f+y, 0.0f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), }, { 25.0f, 350.0f+y, 0.0f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), }, { 775.0f, 250.0f, 0.0f, 1.0f, D3DCOLOR_XRGB(0, 0, 255), }, { 800.0f, 250.0f, 0.0f, 1.0f, D3DCOLOR_XRGB(0, 0, 255), }, { 775.0f, 350.0f, 0.0f, 1.0f, D3DCOLOR_XRGB(0, 0, 255), }, { 800.0f, 350.0f, 0.0f, 1.0f, D3DCOLOR_XRGB(0, 0, 255), }, { 395.0f, 295.0f, 0.0f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, { 405.0f, 295.0f, 0.0f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, { 395.0f, 305.0f, 0.0f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, { 405.0f, 305.0f, 0.0f, 1.0f, D3DCOLOR_XRGB(255, 255, 255), }, };

Not being able to transfer ideas/knowledge into code is going to be an ongoing problem.

@pbivens67 I don't know you so I can't speak to your situation. Just know that it (gamedev programming) is not going to get any easier. It's not going to someday ‘click’ and everything magically falls into place. If you're not enjoying it now, you will never enjoy it.

Search “chatgpt programming”. That might be a lifeline of sorts.

I am not giving up on programming, I am not the best, but I try hard. I am still studying my c++ book and am on the chapter on recursion

While recursion is a useful concept, I don't think it will help you with your current trouble areas, which seems to be not quite being able to create some structure in your problem so it becomes easier to solve it.

Working on that may be more useful for you.

Did you ever try solving programming exercises or write eg a hangman game? No DX9 setup, just a main function that runs the computation and prints the result. Try to use functions that each do some part of the computation.
