I've been ripping my hair of trying to solve my problem, so I really hope that someone has any idea of how to solve it:
I've defined a new float and want to do a indentation (or similar) within it.
\usepackage{float}
\newfloat{algfloat}{h}{ext}[chapter]
\begin{document}
\begin{algfloat}
Not Indented text.\\
\indent Indented text.\\
\hspace{1 pt} Indented text.\\
\end{algfloat}
\end{document}
The problem is that there is no indentation anywhere in the pdf!
(The "\\" are needed for creating a new line)
Does any one have an idea of a solution? I've been googeling it for hours! And I haven't found any alternative way of doing something similar.
EDIT: Finally solved!

Problem was that parindent is, for some reason, set to "0" only within my custom float. So the solution is:
\setlength{\parindent}{10pt}, togheter with \noindent for avoiding a indent on the first row.
Hope this will help someone else!
I must say I regret choosing Latex instead of Word for writing my Master Thesis. It has taken me about 8 hours to solve this problem. I Word I've would have done it in less than 5min.
