OpenSSN - What is OpenSSN?

==========================



OpenSSN is a submarine simulation (subsim) which tries to emulate

the behaviour of modern submarines. The player is placed in command

of a submarine and is able to move about in a deep ocean environment.



Combat missions are now being added to OpenSSN, and ships with

sonar will run from torpedoes and, if they can detect the player,

will return fire.



Why a subsim?

======================



I've always been a fan of subsims and played commercial games,

but couldn't find a modern subsim for open source operating systems

(such as Linux and FreeBSD). Danger from the Deep is available,

but it's stictly for World War II u-boats, and has relatively high

graphics requirements. Looking around I found a half dozen or so

subsims that had begun and dropped away shortly after beginning development.



The LinuxSSN project had laid a solid foundation before the developers

dropped the project and I decided to pick up where they left off.

The heart of OpenSSN comes from their project and attempts to further

their work.

What do I need to build OpenSSN?

=================================



To build OpenSSN you'll need a C++ compiler (GNU's Compiler Collection

is recommended) and the following development libraries:



SDL

SDL_gfx

SDL_image

SDL_mixer



Assuming the above libraries are installed, it should be possible to

build OpenSSN with the following commands



tar zxf openssn-1.4.tar.gz

cd openssn

make



Running OpenSSN

==================================



Once OpenSSN has built, an executable file (called openssn) will

be placed in the top level directory. From there

the game can be run with the command:



./openssn



The following command line parameters are recognized:



-w		Run in windowed mode, this is the default

-f		Run in full screen

-s		Enable sound effects

-v		Display version number and exit

-h		Display help and exit

-m  	Load a specific mission



Control Keys

===========================



The player's submarine can be controlled with either the mouse 

or keyboard commands. The following key commands are recognized.
