Warum scrollen meine ASCII -Animation weiter nach unten, anstatt auf Windows Console (C ++) zu aktualisieren? ⇐ C++

Ich versuche, eine einfache ASCII 3D Spinning Cube -Animation in der Windows -Konsole mit C ++ zu erstellen.#include

COORD pos{(SHORT)x, (SHORT)y};
SetConsoleCursorPosition(hConsole, pos);

Obwohl ich "\ x1b [H" verwende, um den Cursor wieder nach oben zu bewegen, wird die Konsole immer noch nach unten geprüft-jeder neue Rahmen wird unten unter dem vorherigen gedruckt. (IM Verwenden Sie VSCODE unter Windows 11). < /P>
Vielen Dank! (CMD, PowerShell, Windows -Terminal) < /p>
