[Tex/LaTex] Vertical Spacing After Paragraph Heading

sectioningsections-paragraphsspacing

I can't manage to control vertical spacing after (and before) paragraph which I've customized.

\paragraph{Çatışma}
Birden fazla düşman birimin karşılıklı yok etme ….

And here is what i used to customize this:

    \documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[turkish]{babel}
\usepackage[left=3.50cm, right=2.50cm, top=3.00cm, bottom=3.00cm,nohead,nofoot]{geometry}
 \usepackage[overload]{textcase} 
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{pslatex}
\usepackage[explicit]{titlesec}
\usepackage[font=small,format=plain,labelfont=bf,up,textfont=it,up]{caption}
\usepackage{graphicx,epstopdf}
\epstopdfsetup{update}
\DeclareGraphicsExtensions{.ps}
\epstopdfDeclareGraphicsRule{.ps}{pdf}{.pdf}{epstopdf er.ps --outfile \OutputFile}
\usepackage{setspace}
\setlength{\parindent}{0pt}
\renewcommand{\thefigure}{\arabic{section}.\arabic{figure}}
\setlength{\parskip}{\baselineskip}

\addto\extrasturkish{\uccode`i=\string"9D \lccode`I=\string"19 }
\addto\noextrasturkish{\uccode`i=`I \lccode`I=`i }

\titleformat{\section}
  {\normalfont\normalsize\bfseries}{\thesection}{1em}{\MakeTextUppercase{#1}}
\titleformat{\subsection}
  {\normalfont\normalsize\bfseries}{\thesubsection}{1em}{#1}
\titleformat{\subsubsection}
  {\normalfont\normalsize\bfseries\itshape}{\thesubsubsection}{1em}{#1}

\raggedbottom
\usepackage{chngcntr}

\setcounter{secnumdepth}{6}
\renewcommand\theparagraph{\Alph{paragraph}}
\makeatletter
\renewcommand\paragraph{\@startsection  {paragraph}
                                        {4}
                                        {\z@}%
                                        {0ex\@plus -0ex \@minus -.2ex}%
                                        {0.0001pt \@plus .2ex}%
                                        {\itshape\normalsize}}

\counterwithin{paragraph}{subsubsection}

\titlespacing\section{0pt}{-12pt plus 4pt minus 2pt}{-10pt plus 2pt minus 2pt}
\titlespacing\subsection{0pt}{-12pt plus 4pt minus 2pt}{-10pt plus 2pt minus 2pt}
\titlespacing\subsubsection{0pt}{-12pt plus 4pt minus 2pt}{-10 pt plus 2pt minus 2pt}
\titlespacing\paragraph{0pt}{-12pt plus 4pt minus 2pt}{-10 pt plus 2pt minus 2pt}


\usepackage{graphicx,epstopdf}
\epstopdfsetup{update}
\DeclareGraphicsExtensions{.ps}

\newcounter{subcount}





\begin{document}

I'm not even sure which packages effect each other and why… Any kind of help will be nice.
Thanks in advance.

Best Answer

You mix up standard LaTeX style for section heading definitions (via \@startsection) with the declarative method used by titlesec. And that doesn't work.

Remove the redefinition for \paragraphand instead use:

\titleformat{\paragraph} {\itshape\normalsize}{\theparagraph}{1em}{#1}
\titlespacing\paragraph{0pt}{-12pt plus 4pt minus 2pt}{-15 pt plus 2pt minus 2pt}

and adjust the values for spacing as you wish.

Standard LaTeX method doesn't work if you have a \parskip that is big (eg \baselineskip) as in the \@startsection command the \parskipis always added to all dimensions. And if you try to go nevative to account for it it changes from display heading to inline heading ... a documented bug (aka feature)
