Tikz 鏈,最左邊節點的一側,粗體

Tikz 鏈,最左邊節點的一側,粗體

大家早安。其實這是我第一次在這裡寫文章,所以我感謝所有願意回覆的人。我正在寫本科論文,目前正致力於繪製圖靈機。我想做的是這樣的:

除了我想讓第一個節點的左側(只有左側,而不是所有 4 個邊)非常厚。到目前為止我所做的如下:

\begin{tikzpicture}
\edef\turingtapesize{0.7cm}
\tikzstyle{tape}=[draw,minimum size=\turingtapesize]
\tikzset{
    leftmostnode/.style={
        draw,minimum size=\turingtapesize,
        append after command={% <= for the leftside line of the leftward node
            \pgfextra{%
            \begin{pgfinterruptpath}
            \begin{pgfonlayer}[foreground]
                \draw[verythick] (\tikzlastnode.south west)--(\tikzlastnode.north west);
            \end{pgfonlayer}
            \end{pgfinterruptpath}
            }
        }
    }
}

% Drawing the tape itself
\begin{scope}[start chain=0 going right,node distance=0mm]
    \node[on chain=0,tape] (b)  {0};
    \node[left=of b,leftmostnode](a){1};
    \node[on chain=0,tape] (c)  {1};
    \node[on chain=0,tape] (d)  {0};
    \node[on chain=0,tape] (e)  {1};
    \node[on chain=0,tape] (f)  {0};
    \node[on chain=0,tape] (g)  {0};
    \node[on chain=0,tape] (h)  {1};
    \node[on chain=0,tape] (i)  {1};
    \node[on chain=0,tape] (l)  {$\sqcup$};
    \node[on chain=0,tape] (l)  {$\sqcup$};
    \node[on chain=0,tape] (l)  {$\sqcup$};
\end{scope}
\end{tikzpicture}

但我收到一個錯誤:

抱歉,無法找到請求的圖層「[」。也許你拼錯了?

\nodeleft=b 的最左邊節點 {1};

我還可以問你如何獲得那種“電鋸”(這個術語存在嗎?)的磁帶末端?謝謝,乾杯;)來源:1 2

編輯按照 moospit 的建議,我解決了「厚度問題」。現在只剩下我來創造那條特殊的鋸齒線了;)

EDIT2 我剛剛看到你的回覆。我以稍微不同的方式解決了這個問題。

最終結果如下: 在此輸入影像描述

答案1

如何使用您的tape節點樣式a並在鏈代碼之後添加以下內容:

\draw [very thick] (a.south west) -- (a.north west);

或者

\draw [line width=.1cm] (a.south west) -- (a.north west);

這樣您就可以在節點上方增加一條額外的線a

編輯:更新鏈末端的鋸齒形節點 (MWE)

這裡還有一些關於您的鋸齒形節點的資訊。我zigzag在下面描述的路徑的一部分上使用了 -decoration。只需zigzag segment length根據您的需求調整和幅度即可。

請注意將outer sep鏈節點的設為0,否則之字形路徑將與north eastsouth east座標產生一些偏移。

\documentclass[tikz, border=5mm]{standalone}

\usetikzlibrary{decorations.pathmorphing, calc}

\begin{document}
 \begin{tikzpicture}
  \node [draw, outer sep=0pt] (n) {n};
  \draw (n.north east) -- ++(.1,0) decorate [decoration={zigzag, segment length=.12cm, amplitude=.02cm}] {-- ($(n.south east)+(+.1,0)$)} -- (n.south east) -- cycle;
 \end{tikzpicture}
\end{document}

再編輯一次:無法抗拒;)。只需重寫程式碼即可使鏈可擴展以容納更多元素:

如果您還有更多問題,請提問。如果您願意,您可以輕鬆地更改zigzag一些。snakes
