Information on playing the game can be found in the manual and in the file "QuickStart.txt" in the kohan_demo installation directory. The first time you run Kohan it will create a ~/.loki/kohan_demo directory. Saved games, temporary files, and preferences will be stored here. The following arguments may be given to Kohan: [-h | --help] Display this help message [-v | --version] Display the game version [-f | --fullscreen] Run the game fullscreen [-w | --windowed] Run the game in a window [-s | --nosound] Do not access the soundcard [-c | --nocdrom] Do not access the CD-ROM [-u | --update] Run the Loki auto-update tool [-x | --x11cursor] Use the X11 hardware mouse cursor [-d | --dga] Use DGA 2.0 acceleration (unsupported) Use Alt-Enter to toggle fullscreen mode. Use Ctrl-G to toggle mouse grabbing. Use Ctrl-Z to iconify the game when it is run in a window. The Print Screen key will save the current screen to the ~/.loki/kohan directory. If the Print Screen, Pause, or Alt-# keys are not working, make sure your window manager is not overriding them. Text input widgets have standard UNIX keybindings. Ctrl-A - Move to beginning of line Ctrl-E - Move to end of line Ctrl-B - Move backwards Ctrl-F - Move forwards Ctrl-U - Erase line Ctrl-D - Delete character Ctrl-C - Copy to X clipboard Ctrl-V - Paste from X clipboard ------------------- (4) TROUBLESHOOTING ------------------- The following are some of the more common problems you might have, and recommended solutions: Q: There is no game sound. A: First, check all your connections between your speakers and your computer. Make sure your speakers are turned on and receiving power. Make sure the volume is not turned down all the way. You can change sound and music volume in the 'Game Options' window. If none of the above suggestions works, try producing sound in another program. If that does not work, make sure you have the sound driver enabled in your kernel. If you are running KDE, make sure that the artscd sound daemon has released the sound card. Finally, go to http://www.opensound.com/ to see whether a commercial driver is available for your sound card. Q: I am playing in windowed mode and I can't scroll at all. A: You can press CTRL-G to toggle whether or not the mouse is grabbed. When the mouse is grabbed, you can scroll easily, but cannot access other applications on the desktop. Q: I have the mouse grabbed, but I still can't scroll. A: You have three different options for scrolling: - Run the game in fullscreen mode - Use the arrow keys or middle button drag to scroll the map - Use the mousewheel and Ctrl-mousewheel to scroll the map - Set the environment variable SDL_MOUSE_RELATIVE=1 Q: What is this DGA 2.0 acceleration option? A: XFree86 4.0 provides a way for X11 applications to grab control of the display and use hardware acceleration for blitting. Kohan can take advantage of this by passing it the "--dga" command- line option when starting up. There are several caveats however: - This option is COMPLETELY UNSUPPORTED. While we've seen it working properly on several DGA implementations, it hasn't been fully tested on all X server and video card configurations. - It requires root permissions to work properly. We have added experimental support for using DGA as a normal user if you have the framebuffer console working, but this is even more unsupported. :) - You can't toggle between windowed and fullscreen operation. Note, Kohan also works on the framebuffer console, unsupported. Q: Can I host a game behind a firewall? A: Yes, you need to have IP masquerading enabled on your firewall, and then forward UDP packets to the firewall on ports 17437 and 3855 to the internal machine that is hosting the game. As always, opening network services inside your firewall introduces a security risk, so don't do it unless you're comfortable taking that risk.
