Define style in TikZ

Question

I have the following code

\documentclass[tikz,border=5pt]{standalone}
\usetikzlibrary{positioning,arrows}

\definecolor{babyblue}{rgb}{0.54, 0.81, 0.94}

\begin{document}
\begin{tikzpicture}

% heads
\node[circle,fill,minimum size=4.5mm] (head) {};
\node[circle,fill,minimum size=4.5mm,right = 50pt of head] (head2) {};

% bodies
\node[rounded corners=2pt,minimum height=1.3cm,minimum width=0.4cm,fill,below = 1pt of head] (body) {};
\node[rounded corners=2pt,minimum height=1.3cm,minimum width=0.4cm,fill,below = 1pt of head2] (body2) {};

% texts
\node[below = 1pt of body] {Buyer};
\node[below = 1pt of body2] {Broker};

% arms
\draw[line width=1mm,round cap-round cap] ([shift={(2pt,-1pt)}]body.north east) --++(-90:6mm);
\draw[line width=1mm,round cap-round cap] ([shift={(2pt,-1pt)}]body2.north east) --++(-90:6mm);

\draw[line width=1mm,round cap-round cap] ([shift={(-2pt,-1pt)}]body.north west)--++(-90:6mm);
\draw[line width=1mm,round cap-round cap] ([shift={(-2pt,-1pt)}]body2.north west)--++(-90:6mm);

% legs
\draw[ultra thick,white,-round cap] (body.south) --++(90:6.2mm);
\draw[ultra thick,white,-round cap] (body2.south) --++(90:6.2mm);

% stock exchange
\node[rounded corners=3pt,minimum height=1.3cm,minimum width=0.35cm,fill,right = 60pt of body2] (pillar1) {};
\node[rounded corners=3pt,minimum height=1.3cm,minimum width=0.35cm,fill,right = 8.5pt of pillar1] (pillar2) {};
\node[rounded corners=3pt,minimum height=1.3cm,minimum width=0.35cm,fill,right = 8.5pt of pillar2] (pillar3) {};

\node[rounded corners=3pt,minimum height=0.35cm,minimum width=1cm,fill,below left = 2pt and -12pt of pillar1] (hpillar1) {};
\node[rounded corners=3pt,minimum height=0.35cm,minimum width=1cm,fill,below right = 2pt and -12pt of pillar3] (hpillar2) {};

\node[rounded corners=3pt, minimum height=0.05cm, minimum width=2.85cm, fill, above = 2pt of pillar2] (mroof) {};

\draw[line width=1mm, round cap-round cap] ([shift={(4.5pt,-41.3pt)}]pillar2.north east) --++(-180:7mm);
\draw[line width=1mm, round cap-round cap] ([shift={(4.5pt,-45.3pt)}]pillar2.north east) --++(-180:7mm);
\draw[line width=1mm, round cap-round cap] ([shift={(4.5pt,-49.3pt)}]pillar2.north east) --++(-180:7mm);

\draw[ultra thick,fill,rounded corners=3pt] (3.94,0.17) -- (6.82,0.17) -- (5.38,0.82) -- cycle;

% arrows

\draw[->,thick,babyblue] (0.4,-0.6) -- (1.82,-0.6);
\draw[->,thick,babyblue] (0.4+2.2,-0.6) -- (1.82+2.2,-0.6);

\end{tikzpicture}

\end{document} 

that produces the figure below.

Is there a way I can define the man and the building as a style by means of tikzset? And have coordinates as arguments, so I can place them wherever I want?

Answer 1

I've created a pic with two args: a sort of node name (for easy reference in the successive \draw commands) and the text of the picture.

\documentclass[tikz,border=5pt]{standalone}
\usetikzlibrary{positioning,arrows,fit}
\tikzset{%
    pics/man/.style 2 args={code={%
            % head
            \node[circle,fill,minimum size=4.5mm] (head) {};
            % body
            \node[rounded corners=2pt,minimum height=1.3cm,minimum width=0.4cm,fill,below = 1pt of head] (body) {};
            % text
            \node[below = 1pt of body] {#2};
            % arms
            \draw[line width=1mm,round cap-round cap] ([shift={(2pt,-1pt)}]body.north east) --++(-90:6mm);
            \draw[line width=1mm,round cap-round cap] ([shift={(-2pt,-1pt)}]body.north west) --++(-90:6mm);
            % legs
            \draw[ultra thick,white,-round cap] (body.south) --++(90:6.2mm);
            \node[inner ysep=0pt, fit=(head)(body)] (#1) {};
        }},
}
\definecolor{babyblue}{rgb}{0.54, 0.81, 0.94}

\begin{document}
    \begin{tikzpicture}

    \pic {man={buy}{Buyer}}; 
    \pic[right=50pt] {man={bro}{Broker}};   
    % stock exchange
    \node[rounded corners=3pt,minimum height=1.3cm,minimum width=0.35cm,fill, below right=-3.7em and 5em of bro] (pillar1) {};

    \node[rounded corners=3pt,minimum height=1.3cm,minimum width=0.35cm,fill,right = 8.5pt of pillar1] (pillar2) {};
    \node[rounded corners=3pt,minimum height=1.3cm,minimum width=0.35cm,fill,right = 8.5pt of pillar2] (pillar3) {};

    \node[rounded corners=3pt,minimum height=0.35cm,minimum width=1cm,fill,below left = 2pt and -12pt of pillar1] (hpillar1) {};

    \node[rounded corners=3pt, minimum height=0.05cm, minimum width=2.85cm, fill, above = 2pt of pillar2.north] (mroof) {};

    \draw[line width=1mm, round cap-round cap] ([shift={(4.5pt,-41.3pt)}]pillar2.north east) --++(-180:7mm);
    \draw[line width=1mm, round cap-round cap] ([shift={(4.5pt,-45.3pt)}]pillar2.north east) --++(-180:7mm);

    % arrows    
    \draw[shorten >= 2pt, shorten <= 2pt,->,thick,babyblue] (buy) -- (bro);
    \draw[shorten <= 2pt,->,thick,babyblue] (bro) -- (bro-|SE.west);
