Graphics, Figures & Tables ⇒ tikz nodes connection problem

[Bahurin]

Dear all!
I cannot to find solution of my problems.
I created short code:

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes, snakes, arrows}

\tikzset{
	sum/.style={circle,draw=black,fill=white,thick, inner sep=0pt,minimum size=6mm},
	gain/.style={regular polygon,regular polygon sides=3, draw = black, fill=white,thick, minimum size=6mm},
	none/.style={draw=none,fill=none}}

\begin{document}
	
	\begin{tikzpicture}[thick, >=stealth]
		
		\node(w) at (0,0) [gain, rotate = -90]  {};	
		\node(sum0) at ( 2,0) [sum] {$+$};
		\draw[->] (w) -- (sum0) ;
		\draw[*->] (1,0) -- (1,-1) ;
		

	\end{tikzpicture}
	
	
\end{document}

I created 2 nodes: triangle and circle and I want to connect nodes (see picture).

But line from triangle node likes bad. Also I want to create branch from my connection like this

Code: Select all

\draw[*->] (1,0) -- (1,-1) ;

but beggining marker also just touch main line.

Could you tell me how can I solve these problems?
Thanks!

Hi Bahurin,

very good minimal example and picture! So it makes fun to read and to test it.

You could simply extend the lines, that is, shorten by a negative value:

Code: Select all

     \draw[->,  shorten <=-1] (w)   -- (sum0) ;
     \draw[*->, shorten <=-3] (1,0) -- (1,-1) ;
