How to make a loop with multiple nodes?

Question

I want to make this

\documentclass{article}
\usepackage{tikz}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{mathrsfs}
\usepackage{textcomp}
\usetikzlibrary{arrows,snakes,automata,backgrounds,calc, positioning,quotes}

%\begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=3cm,thick,main node/.style={circle,fill=#1!0,draw,font=\sffamily\Large\bfseries}]

\begin{tikzpicture}[
        ->,    > = stealth',
       shorten > = 1pt,auto,
   node distance = 3cm,
      decoration = {snake,   % <-- added
                    pre length=3pt,post length=7pt,% <-- for better looking of arrow,
                    },
main node/.style = {circle,draw,fill=#1!0,
                    font=\sffamily\Large\bfseries},
                    ]

\node[main node=black] (0) {$\omega$};
\node[main node=black] (1)[above of=0] {$\alpha$};
\node[main node=black] (2) [above of=1]{$\alpha_0$};
\node[main node=black](3)[above of=2]{$\alpha_1$};
\node[main node=black] (4) [above of=3]{$\beta$};
\node[main node=black](5)[right of=4]{$\beta_0$};
\node[](6)[above of =3]{};
\node[main node=black](7)[left of=4]{$\beta_1$};
\node[main node=black](8)[right of =1]{$\beta_1^{'}$};
\node[](9)[left of=8]{};
\node[main node=black](10)[right of=8]{$\beta_1^{''}$};
\node[](11)[right of=10]{};

  \path[every node/.style={font=\sffamily\small}]

    (0) edge[very thick, color=blue] node [] {} (1)
    (1) edge[very thick, color=magenta]node[right]{CHILD$_{oot}$}(2)
    (2) edge[draw=gray, very thick, decorate] node [right] {SEALED} (3)
    (3) edge[very thick, color=cyan] node [right] {ADULT$_{oot}$} (4)
    (4) edge[very thick, color=red]node[above]{DEFEAT}(5)
    (4) edge[very thick, color=green]node[above]{SUCCESS}(7)
    (10) edge[very thick, color=cyan]node[]{ADULT}(11)
    (1) edge[very thick, color=magenta]node[]{CHILD}(8)
    (8) edge[draw=gray, very thick, decorate]node[]{SEALED?}(10)
    (7) edge[bend right, very thick, draw=gray]node[left]{BACK IN TIME}(1)

   ;

\end{tikzpicture}
\end{document}

look like this

I've never made arrows bend around a circle like this before. Any ideas?

Answer 1

I am not sure of the exact setup you want for your nodes, as it does not seem possible to fit the topology of your tikz graph to that you drew by hand.

This solution is rather naive.

\documentclass[tikz, border =3pt]{standalone}
\usetikzlibrary{arrows,snakes}
\begin{document}

\begin{tikzpicture}
  [
            ->,    > = stealth',
           shorten > = 1pt,auto,
       node distance = 4cm,
          decoration = {snake,   % <-- added
                        pre length=3pt,post length=7pt,% <-- for better looking of arrow,
                        },
    main node/.style = {circle,draw,fill=#1!0,
                        font=\sffamily\Large\bfseries},
  ]
  \def\r{3.5}

  \node[main node=black] (2) at (0:\r) {$\alpha_0$};
  \node[main node=black] (3) at (90:\r) {$\alpha_1$};
  \node[main node=black] (4) at (180:\r) {$\beta$};
  \node[main node=black] (7) at (-90:\r) {$\beta_1$};
  \node[main node=black] (1) at (2|-7) {$\alpha$};
  \node[main node=black] (5) [left of=4] {$\beta_0$};
  \coordinate                (6) [above of=3] {};
  \node[main node=black] (0) [below of=1] {$\omega$};
  \node[main node=black] (8) [right of=1] {$\beta_1^{'}$};
  \coordinate                (9) [left of=8]  {};
  \node[main node=black] (10)[right of=8] {$\beta_1^{''}$};
  \node[]                (11)[right of=10]{};

  \path[every node/.style={font=\sffamily\small}]

    (0) edge[very thick, color=blue] node [] {} (1)
    (1) edge[very thick, color=magenta]node[right]{CHILD$_{oot}$}(2)
    (2) edge[draw=gray, very thick, decorate, in=0, out=90] node [anchor=south west] {SEALED} (3)
    (3) edge[very thick, color=cyan, in=90, out=180] node [anchor=south east] {ADULT$_{oot}$} (4)
    (4) edge[very thick, color=red]node[above]{DEFEAT}(5)
    (4) edge[very thick, color=green, in=180, out=-90]node[anchor=north east]{SUCCESS}(7)
    (10) edge[very thick, color=cyan]node[]{ADULT}(11)
    (1) edge[very thick, color=magenta]node[]{CHILD}(8)
    (8) edge[draw=gray, very thick, decorate]node[]{SEALED?}(10)
    (7) edge[very thick, draw=gray]node[anchor = north]{BACK IN TIME}(1)

   ;

\end{tikzpicture}
\end{document}
