Draw striped arrowhead in tikz

tikz-arrowstikz-pgf

I want to draw an arrow with a striped arrowhead using tikz. I can't find anything in the tikz docs to do this.

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}[very thick,font=\sffamily\Large]
\draw[-{Latex[length=30mm,angle'=10]}] (0,-2) -- (0,3);
\end{tikzpicture}
\end{document}

I want to make something like the below figure. Black line with arrowhead that has evenly spaced orange/white stripes:

Best Answer

The inset is misused, it denoted the number of stripes (including the white/transparent ones). An even number will lead to the line ending at a white stripe.

Code

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows.meta, bending}
\pgfdeclarearrow{
  name = Striped Triangle,
  defaults = {
    length  = +3pt 4.5 .8,
    width'  = +0pt .75,
    inset'  = +13pt,
    angle=+60:+2.7pt +3.6,
  },
  setup code={%
    \pgfarrowssettipend{0pt}%
    \pgfarrowssetbackend{-\pgfarrowlength}%
    \pgfarrowssetlineend{\dimexpr-\pgfarrowlength+.001pt}% visual things
    \pgfarrowsupperhullpoint{0pt}{0pt}%
    \pgfarrowsupperhullpoint{-\pgfarrowlength}{.5\pgfarrowwidth}%
    \pgfarrowssavethe\pgfarrowlength
    \pgfarrowssavethe\pgfarrowwidth
    \pgfarrowssavethe\pgfarrowinset
    \pgfmathreciprocal{\pgfarrowinset}%
    \let\pgfarrowstripedtrianglefrac\pgfmathresult
    \pgfarrowssave\pgfarrowstripedtrianglefrac
  },
  drawing code={%
    \pgfmathloop % could use qicker \pgfmathmultiply@ here
      \pgfmathmultiply{\pgfmathcounter-1}{\pgfarrowstripedtrianglefrac}\let\near\pgfmathresult
      \ifdim\pgfmathcounter pt=\pgfarrowinset \def\far{1}% just use 1 instead of n*1/n
      \else
        \pgfmathmultiply{\pgfmathcounter}{\pgfarrowstripedtrianglefrac}\let\far\pgfmathresult
      \fi
      \pgfpathmoveto{\pgfqpointscale{\near}{\pgfqpoint{-\pgfarrowlength}{+.5\pgfarrowwidth}}}%
      \pgfpathlineto{\pgfqpointscale{\far }{\pgfqpoint{-\pgfarrowlength}{+.5\pgfarrowwidth}}}%
      \pgfpathlineto{\pgfqpointscale{\far }{\pgfqpoint{-\pgfarrowlength}{-.5\pgfarrowwidth}}}%
      \pgfpathlineto{\pgfqpointscale{\near}{\pgfqpoint{-\pgfarrowlength}{-.5\pgfarrowwidth}}}%
      \pgfpathclose
      \ifdim\pgfinteval{1+\pgfmathcounter}pt<\pgfarrowinset\relax
      \edef\pgfmathcounter{\pgfinteval{\pgfmathcounter+1}}%
    \repeatpgfmathloop
    \pgfusepathqfill
  },
  parameters={\the\pgfarrowlength,\the\pgfarrowwidth,\the\pgfarrowinset}
}
\tikzset{>={Striped Triangle[fill=orange, angle'=30]}}
\begin{document}
\begin{tikzpicture}[ultra thick]
\foreach[count=\i] \ang in {0, 30, ..., 359}
  \draw[-{>[inset=2*\i-1]}] (0,0) -- (\ang:.7);
\end{tikzpicture}
\begin{tikzpicture}
\foreach[count=\i] \bendmode in {quick, flex, bend}{
\tikzset{yshift=-\i cm}
\draw [red!25,line width=1mm] (-1,0) -- (1,0);
\draw [red,line width=1mm,-{[\bendmode]>.>>}]
  (-1,-.5) node[right, black] {\bendmode}
  .. controls (0,-.5) and (0,0) .. (1,0);
}
\end{tikzpicture}

[Tex/LaTex] get an extra white page before the TikZ picture

use

\begin{landscape}
\resizebox{!}{0.95\textheight}{\input{erd.tikz.tex}}
\end{landscape}

The image is too big. The reason why it is placed on the following page.

[Tex/LaTex] Drawing rectilinear curves in Tikz, aka an Etch-a-Sketch drawing

\draw (20,12) -- ++(2,0) -- ++(0,2) -- ++(-3,0) -- ++(45:3);

Use ++ before each new incremental coordinate to make it relative to the last one and put the pencil there.

Here's a complete example:

\documentclass{article}
\usepackage{tikz}
\begin{document}
\tikz\draw (20,12) -- ++(2,0) -- ++(0,2) -- ++(-3,0) -- ++(30:3) {[rounded corners=10pt]-- ++(5,0) -- ++(0,-6)} -- ++(-7,0) -- cycle;
\end{document}

Of course, combining this with the -| or |- path operators can simplify the code even further; the following two pieces of code produce the same result:

\tikz\draw (20,12) -- ++(2,0) -- ++(0,2) -- ++(3,0) -- ++(0,1) -- ++(1,0) -- ++(0,-3) -- ++(2,0);\par\bigskip

and

\tikz\draw (20,12) -| ++(2,2) -| ++(3,1) -- ++(1,0) |- ++(2,-3);

I don't think that defining commands in this case adds anything; in fact, I think it reduces the functionality of the existing syntax (which is already simple). The example demonstrates that you can use, for example, polar coordinates and modify (up to TikZ limitations) the path attributes midways; even if the current question doesn't require this, it's a good thing to have the possibility to do those kind of modification if they are required.
