Couldn't find a recent run-down on the process, so I documented my own (streamlined) process (excluding all dead-ends and rage-quits). If this thread is inappropriate in this forum, please feel free to delete or move it.
This is a guide for installing and running the AGS editor on Ubuntu 64-bit. At the moment of writing this, I'm running Kubuntu 13.10 (codename Saucy), which is a KDE "flavour" of Ubuntu. Here's what I did and (hopefully everything) you need to do:
1) Get the latest version of Wine
Head to https://www.winehq.org/download/ubuntu and add the Wine PPA to your package sources. Then run:
sudo apt-get update
sudo apt-get install wine
2) Create a separate 32-bit wine prefix
WINEARCH=win32 WINEPREFIX=~/.wine32 winecfg
Just press â€Ok†if you don't know a particular change to the default Wine setup you wish to apply to this prefix.
3) Install .NET 2.0 on this prefix.
env WINEPREFIX=~/.wine32 winetricks dotnet20
4) Download the latest AGS install executable
Head to http://www.adventuregamestudio.co.uk/site/ags/ and download the executable. Then run (in the folder you downloaded to):
env WINEPREFIX=~/.wine32 wine AGS-3.3.0.exe
Exchange â€AGS-3.3.0.exe†for whatever file you've downloaded.
5) Start the editor
env WINEPREFIX=~/.wine32 wine ~/.wine32/drive_c/"Program Files"/"Adventure Game Studio 3.3.0"/AGSEditor.exe
This snippet assumed you made no changes to the suggested installpath and is ideally saved as a shortcut on your system.
