如何在 TikZ 中的节点下方绘制圆形箭头和多行文本？

我有一个如下所示的投影仪框架。它绘制了两个节点tikzpeople，然后在它们之间绘制了箭头。但是，我想绘制另外两个东西。首先，我想在左侧图标下方添加多行文本，并在右侧图标上方绘制带注释的圆形箭头。我想要实现的目标如下图所示。

\documentclass[xcolor=table,10pt,aspectratio=169]{beamer}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[american]{babel}

    calc,
    chains,
    decorations,
    decorations.text,
    decorations.pathmorphing,

    positioning,

标准循环和自定义循环：

\documentclass[tikz, border=1cm]{standalone}
\usepackage{tikzpeople}
\begin{document}
\begin{tikzpicture}
\node[charlie, minimum size=2cm, align=center] (A) at (0,0) {$(\mathsf{msk},\mathsf{mpk}) \gets \mathsf{Setup}(1^\lambda, \mathcal{F})$\\Text also here} edge[loop above] node {Text} ();
\node[devil, minimum size=2cm] (B) at (5,0) {};
\draw[->] (B) to[out=45, in=90, looseness=5] node[above right]{Text} (B);
\end{tikzpicture}
\end{document}

Two person figures with loops above

以下是我的想法：

\documentclass[xcolor=table,10pt,aspectratio=169]{beamer}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[american]{babel}
\usepackage{amsmath,amssymb,amsthm}
\usepackage[beamer,customcolors]{hf-tikz}
\usepackage{booktabs} % Tables
\usepackage{tikz}
\usetikzlibrary{
    arrows,
    calc,
    chains,
    decorations,
    decorations.text,
    decorations.pathmorphing,
    matrix,
    overlay-beamer-styles,
    positioning,
    shapes,
    tikzmark
}
\usepackage{tikzpeople}
\tikzset{hl/.style={
        set fill color=red!80!black!40,
        set border color=red!80!black,
    },
}

\usepackage{lipsum}
\begin{document}

    \begin{frame}{Security Notion - IND-CPA-FE}
        \begin{center}
            \begin{tikzpicture}[every text node part/.style={align=center}]
            \node[name=a,charlie,minimum size=2cm] (A) at (0,0) {$(\mathsf{msk},\mathsf{mpk}) \gets \mathsf{Setup}(1^\lambda, \mathcal{F})$ \\Hello is anybody out there ?};
            \node[name=b,devil,minimum size=2cm] (B) at (10,0) {};
            {\draw[->] (1.5,1.25) -- (8,1.25) node[midway, above]{$\mathsf{mpk}$};}
            {\draw[->] (8,0.5) -- (1.5,0.5) node[midway, above]{$x_0^*, x_1^*$};}
            {\draw[->] (1.5,-0.25) -- (8,-0.25) node[midway, above]{$c^* \gets \mathsf{Enc}(\mathsf{mpk}, x_b^*)$};}
            {\draw[->] (8,-1) -- (1.5,-1) node[midway, above]{$b'$};}

            \path[->] (B) edge [loop above] +(0,0);
            \end{tikzpicture}
        \end{center}
    \end{frame}

\end{document}

Tiks 有一个不错的loop选择：https://tikz.dev/library-automata

所以我补充道(B) edge [loop above] +(0,0);

多行文本更简单： \\Hello is anybody out there ?}

您还可以添加选项[text width = 50]以获得所需的效果。

当然还有其他方法可以实现这一点。
