我想知道是否可以使用 hexgame 包来制作 Hex 棋盘游戏的箭头演练。有人知道怎么做吗？
这个想法是制作类似此链接中的箭头的东西：
但是在 hexgame 包中，显示的棋盘如下：
如果无法在 hexgame 包中执行此操作，那么如何在 Latex 代码中考虑箭头和粗黑线来制作第一个图像？

这里我使用了 hexboard 包。绘制棋盘 ( \hexboard) 和为单元格着色 ( \hexcellshaded) 是 hexboard 的一部分。该包还有一个\hexconnect用于在两个单元格之间绘制线条的命令，不过我在这里重写了这个命令，以便dotted线条变成虚线。然后，绘制单元格边框的代码在这里是新的，不过是基于 hexboard 中绘制彩色边缘边界的代码。
\documentclass{standalone}
\usepackage{hexboard}
% this redefines the hexboard command \hexconnect so that it has a dotted line instead of a solid one. The difference is ',dotted' in the \draw command
\renewcommand{\hexconnect}[4]{%
\hexcoord{#1}{#2}
\node[minimum size=0,inner sep=0,outer sep=0] (A) at (\xchor em,\ychor em) {};
\hexcoord{#3}{#4}
\node[minimum size=0,inner sep=0,outer sep=0] (B) at (\xchor em,\ychor em) {};
\draw[line width=\hexthinline em,line cap=round,dotted] (A) -- (B);
}
% these commands are based on the code that draws the coloured edge borders in hexboard
% they draw the six parts of a cell border for the cell specified by the two arguments
\newcommand{\bottomrightcellborder}[2]{\hexcoord{#1}{#2}\draw[black,shift={(\xchor em,\ychor em)},line width=\hexedgewidth em,line cap=round] (0 em,-0.577350 em) -- (0.5 em,-0.288675 em);}
