This demo is based on the Pharo 4 OSWindow version, and more recent versions are working fine on linux.
About fullscreen as I said in the previous mail it is possible to enable it, I tried it worked, but I did not do it as I don't think it make sense with this game. I will consider in the future making it work on the latest Pharo version on multiple OS if it makes sense to show people how to do it. I'm busy with other concerns right now. Anyway, it's just one approach, you can use another one. > Cheers, > > Jeff > > > > > > On Sun, Sep 24, 2017 at 7:53 AM Clément Bera <bera.clem...@gmail.com> > wrote: > >> Hi, >> >> I describe in the next paragraphs what I do to build application with >> Pharo at 50 fps.
