以新行开始环境（无 par）

Question

我有自定义环境。我希望我的环境（简单​​地）以新行开始，因为我有自定义的长度\parskip和\parindent。我如何调整我的环境以从新行开始并以一行结束并避免出现像下一个这样的代码？

    \\
    \begin{envenv}
    ...
    \end{envenv}
    \\

Answer 1

\documentclass{article}

\newenvironment{envenv}
 {\par\addvspace{-\parskip}\itshape}
 {\par\addvspace{-\parskip}}
