Configuración de estilos en tikzset

Question

Me enfrento a varios problemas al intentar crear una imagen tikzsety cargarla con diferentes variables.

El tikzset incluye estilos para:

1. partes de la imagen tikz (en el ejemplo, los nodos) y
2. partes que podrían agregarse (en el ejemplo, la ruta)

Mientras tanto, las imágenes deberían tener una escala diferente, lo que parece ser un problema con mi código actual.

\tikzset{

        code = { %
            scale=#1,
            mypathstyle/.style={line width=#2mm, ->}, 
            \begin{scope}
                [scale=#1,  
                %mypathstyle/.style would only work here if path inside scope

            every node/.append style={transform shape},

            \node(1) [circle,draw=black,fill=white,thick, font=\bfseries] {$1$};

Loading without parameter works\\[2cm]
\begin{tikzpicture}
    \pic {withscope};
\end{tikzpicture} \\

putting everything in tikzpicture works\\

\begin{tikzpicture} [scale=1.5, 
    every node/.append style={transform shape},
    nodestyle/.style={circle,draw=black,fill=white,thick, font=\bfseries},
    mypathstyle/.style={line width=0.2mm, ->}] 
    \node(1) [nodestyle] {$1$};
    \node(2) [right=of 1] [nodestyle] {$2$};
    %path   
    \draw [mypathstyle] (1) -- (2) node[pos=0.5,above] {2};
\end{tikzpicture} \\

scale doesnt work with scope \\

\begin{tikzpicture}[scale=2,mypathstyle/.style={line width=0.5mm, ->}]
    \pic {withscope};
    %   %path   
    \draw [mypathstyle] (1) -- (2) node[pos=0.5,above]  {3};
\end{tikzpicture}   


without scope it works   \\

\begin{tikzpicture}[scale=2,
    every node/.append style={transform shape},
    mypathstyle/.style={line width=0.5mm, ->}]
    \pic {thisisscopeless};
    \draw [mypathstyle] (1) -- (2) node[pos=0.5,above]  {4};
\end{tikzpicture}   

with scope the scale in tkzpicture wont work. You can hand scale through tikzset, but this isnt great\\

\begin{tikzpicture}[scale=3,mypathstyle/.style={line width=0.5mm, ->}]
    \pic {withscope={3,8}};
    %   %path   
    \draw [mypathstyle] (1) -- (2) node[pos=0.5,above]  {5};
\end{tikzpicture}


without mypathstyle in tikzpicture gives an error as "mypathstyle" is unknown\\

\begin{tikzpicture}%[mypathstyle/.style={line width=0.5mm, ->}]
    \pic {withscope={4,8}};
    %   %path   
    \draw [mypathstyle] (1) -- (2) node[pos=0.5,above]  {6};
\end{tikzpicture}   


\end{document}

Mis problemas son: si uso scopeel estilo funciona, pero scaleno. Si no uso scopelos estilos, no funcionará, pero scalefunciona. En ambos escenarios, definir un estilo para algo más fuera del tikzset pero dentro del tikzset tikzpictureno funcionará.

Estoy bastante seguro de que el problema de la última parte radica en algún lugar de la clave de los estilos que defino, pero no sé cómo llamarlo correctamente. ¿Alguien tiene una idea sobre cómo crear un tikzset que defina estilos para el tikzpicture al que se llama y que también tenga contenido que sea escalable a través del entorno tikzpicture?

Muchas gracias

Hay dos problemas:

1. Si dices code={...}, ...tiene que haber algún código, no algo así key=blabla. TúpoderSin embargo , defina claves usando \tikzset, por ejemplo, .
2. Si es así n args=2, los dos argumentos deben pasarse a la picvía \pic {withscope={3}{8}};y no\pic {withscope={3,8}};

Teniendo esto en cuenta, el MWE se convierte en

scale doesn't work with scope \textbf{because the options are local}

    \draw [mypathstyle] (1) -- (2) node[pos=0.5,above]  {4};
\end{tikzpicture}

\begin{tikzpicture}[scale=3,mypathstyle/.style={line width=0.5mm, ->}]

    \draw [mypathstyle] (1) -- (2) node[pos=0.5,above]  {5};
