骑士在 4 x 8 棋盘上移动动画

Question

我想制作一个动画，展示骑士如何在 4 x 8 棋盘上移动，每个方格只访问一次。如果某个方格被访问过一次，我想在方格内放置一个“X”，这样我们就知道骑士已经访问过该方格。我无法实现这一点。

我已附上了一个最小工作示例！请帮忙。

\documentclass[14pt]{extarticle}
\usepackage[margin=1in]{geometry}
\usepackage{xskak,chessboard,amsmath}
\storechessboardstyle{4x8}{maxfield=h4,showmover=false}
\setchessboard{style=4x8,boardfontsize=30pt}
\usepackage{animate}

\makeatletter
\cbDefineNewPiece{white}{C}{\raisebox{\depth}{\cfss@whitepiececolor
$\times$}}



\begin{document}

\begin{center}
\textbf{\Large{Knight's Tour: 1}}\\
\begin{animateinline}[controls]{1}
\chessboard[setblack={Na4}]
