WriteConsoleOutputCharacterW - Where are my new lines? - c++

Question

I'm trying to learn how to use a screen buffer, and I made a mistake that I do not understand. These are the settings for my screen buffer:
wchar_t* screen = new wchar_t[nScreenWidth * nScreenHeight];
for (int i = 0; i < nScreenWidth * nScreenHeight; i++) {
screen[i] = L' ';
}
HANDLE hConsole = CreateConsoleScreenBuffer(GENERIC_READ | GENERIC_WRITE, 0, NULL, CONSOLE_TEXTMODE_BUFFER, NULL);
SetConsoleActiveScreenBuffer(hConsole);
DWORD dwBytesWritten = 0;
WriteConsoleOutputCharacterW(hConsole, screen, (nScreenWidth * nScreenHeight), { 0,0 }, &dwBytesWritten);
I manage to print to it my 2D array but it is weird that it's lying flat in my terminal window (see link to print screen).
Small print screen of my failed 2D array
It's as if all the new lines have been removed. This is my loop that prints my 2D array to "screen".
int g = 0;
while (g < 100) {
WriteConsoleOutputCharacterW(hConsole, screen, (nScreenWidth * nScreenHeight), { 0,0 }, &dwBytesWritten);
for (int i = 0; i < field.difficulty; i++) {
std::this_thread::sleep_for(std::chrono::milliseconds(50));
}
for (int y = 0; y < field.nFieldHeight; y++) {
for (int x = 0; x < field.nFieldWidth; x++) {
screen[(y + 2) * field.nFieldWidth + (x + 2)] = field.matrix[x][y];
}
}
}
Is it possible that I need to write to a coordinate in the screen buffer every time I print a character?

By default the console window is re-sizable and the this causes the output to wrap. You can prevent this by using the following:
// Get console window
HWND hwndWindow = GetConsoleWindow();
// Prevent resize & maximize
LONG lFlags = GetWindowLong(hwndWindow , GWL_STYLE) & ~WS_MAXIMIZEBOX & ~WS_SIZEBOX & ~WS_HSCROLL;
SetWindowLong(hwndWindow , GWL_STYLE, lFlags);
// Get console handle
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
// Set window and buffer size
_SMALL_RECT consoleRect = { 0, 0, SCREEN_W - 1, SCREEN_H - 1 };
SetConsoleScreenBufferSize(hConsole, { SCREEN_W, SCREEN_H });
SetConsoleWindowInfo(hConsole, TRUE, &consoleRect);
