Easy to make a shortcut on the desktop for those who find it handy.
1. Right click on the desktop.
2. Create new / empty file.
3. Name it: AGK.desktop (I called it AGK2.desktop in the image).
4. Double click the file ( or right click and choose text editor).
5. Past this code:
[Desktop Entry]
Name=AGK2
Comment=App game kit 2
Icon=/home/pi/agk/AGKPi/Tier1/Editor/share/icons/hicolor/48x48/apps/agk.png
Exec=agk/AGKPi/AGK
Type=Application
Encoding=UTF-8
Terminal=false
Categories=None;
6. Change directory Icon and Exec if you have the AppGameKit installed in an other directory.
7. And done!
