bk@setstate inserts whitespace

[eranlambooij]

I was playing around with the package and I came across the following issue. When you set points manually (for example through blackpoint and whitepoint) the left hand margin of the generated image grows. I was able to reduce the problem to the bk@setstate macro by trial and error, but since my pgf and tikz skills are bad I could (sadly) not fix it myself.

A MWE would be:

\documentclass{standalone}
\usepackage{tikz-backgammon}
\begin{document}
\double{neutral}{0}
\bk@setstate{0}{white}
...
\bk@setstate{0}{white}
\blackboard

Where if one is to increase the number of set states the margin on the left hand increases.

Hi thanks for the report. The code you've posted doesn't really allow me to reproduce the problem, however. You can't use \bk@setstate inside the main document, and I also don't actually understand the effect you're describing. Can you reproduce it with a complete compilable document using article class, and using only \blackpoint or \whitepoint commands?

For example the following document produces no shift that I can see, but maybe I'm misunderstanding something.

\documentclass[12pt]{article}
\usepackage{tikz-backgammon}
\begin{document}
\blankboard
\foreach\x in {1,...,24}{
\blackpoint{\x}{1}
}
\blackboard
\end{document}

The given code it does not give. So I guess it is because of the standalone class. I get the same behaviour when I add it to a resizebox environment (inside an article class). Basically the following code misbehaves:

\documentclass[12pt]{article}                                                   
\usepackage{tikz-backgammon}                                                    
\begin{document}                                                                
\resizebox{\textwidth}{!}{                                                      
\double{neutral}{0}                                                             
\foreach\i in {1,...,24}{                                                      
\blackpoint{\i}{1}                                                             
}                                                                              
\blackboard                                                                     
}                                                                               
\end{document}    

To see the difference comment out the for loop.

@eranlambooij Thanks for this example. That is indeed an odd behaviour! Turned out to be quite easy to fix. I've updated the package. You still need to add a % after the opening brace of the loop, but the commands themselves no longer introduce spurious spaces.
