xskak 展示某些动作

Question

使用以下代码，是否可以仅显示带有注释的动作而不是所有动作？

\documentclass{beamer}
\usepackage{xskak, chessboard}
\usepackage{verbatim}
\setbeamertemplate{navigation symbols}{}

\makeatletter
\providecommand\xskak@beforecomment{}
\makeatother

\newcommand\getmovestyle[1]{
\ifthenelse
  {\equal{#1}{N}}
  {\def\mymovestyle{[clockwise=false,style=knight]curvemove}}
      {\ifthenelse
    {\equal{#1}{}}
    {\def\mymovestyle{curvemove}}
    {\def\mymovestyle{straightmove}}}}

Answer 1

您可以测试 nag-data 是否为空。请注意，较短的 NAG（例如 $4）也在此字段中：

\documentclass{article}
\usepackage{xskak}
\usepackage{chessboard}
\usepackage{etoolbox}
\makeatletter
\providecommand\xskak@beforecomment{}
\makeatother

\newcommand\getmovestyle[1]{
\ifthenelse
  {\equal{#1}{N}}
  {\def\mymovestyle{[clockwise=false,style=knight]curvemove}}
      {\ifthenelse
    {\equal{#1}{}}
    {\def\mymovestyle{curvemove}}
    {\def\mymovestyle{straightmove}}}}
