For simplicity, base game and expansions can be started from one of the 3 launchers:
launch_openmohaa_base
, this starts OpenMoHAA in Medal of Honor: Allied Assault mode which is the base gamelaunch_openmohaa_spearhead
, this starts OpenMoHAA in Medal of Honor: Allied Assault: Spearhead modelaunch_openmohaa_breakthrough
, this starts OpenMoHAA in Medal of Honor: Allied Assault: Breakthrough mode
Medal of Honor: Allied Assault is the default game, but expansions are also supported.
Medal of Honor: Allied Assault Spearhead and Medal of Honor: Allied Assault Breakthrough are supported in OpenMoHAA using the com_target_game
variable.
To play an expansion, append the following command-line arguments to the executable:
+set com_target_game 1
for the Spearhead expansion (mohaas/mohta, mainta, a.k.a Team Assault)+set com_target_game 2
for the Breakthrough expansion (mohaab/mohtt, maintt, a.k.a Team Tactics)
With com_target_game
, OpenMoHAA will support the network protocol accordingly. The default value of com_target_game
is 0 for the base game (mohaa, main).
On Windows, a shortcut can be created to the openmohaa
executable, with the command-line argument appended from above to play an expansion.
You can now start a local OpenMOHAA server or play on a server.
The argument +set com_target_demo 1
must be appended to command-line to play the game or host a server using demo assets. Allied Assault, Spearhead and Breakthrough demos are supported as long as com_target_game
is set (see above).
The location of user-writable data, like the console logfile, saves and configuration files can be found in different locations depending on the platform:
%APPDATA%\openmohaa
on Windows~/.openmohaa
on Linux~/Library/Application Support/openmohaa
on macOS
There will be one or more subdirectories like in the game installation folder, they match the game being used: either base game main
or expansions mainta
/maintt
.
This is by design since ioquake3 and has two advantages:
- On a multi-user system, each user will have their own configuration file
- It doesn't overwrite the existing MOHAA configuration in the MOHAA installation directory.
If necessary, the location of user-writable data can be changed manually by setting the fs_homepath
variable in the command-line argument. This is useful when running a dedicated server that can only use the game directory to store/read data. The value can be a relative path (relative to the current working directory) or an absolute path. Example:
+set fs_homepath Z:\openmohaa_data
data will be written inside the fully qualified pathZ:\openmohaa_data
+set fs_homepath homedata
will use the subfolderhomedata
in the process current working directory to write data (will be created automatically)+set fs_homepath .
not recommended, will write data inside the process current working directory
The game directory is intended to be read-only, which is the reason why the home path exists. This prevents existing files in the game directory from being accidentally overwritten.
Note that the configuration file isn't created nor written automatically on a dedicated server (omohaaded).
OpenMoHAA has a basic bot system that emulates real players. The maximum number of bots is defined by the sv_maxbots
variable, and the number of initial bots is defined by the sv_numbots
variable. Bots can also be added or removed using the addbot
and removebot
commands.
This feature is a great way to test the gameplay and mods.
Note that maps must have path built for bots to move, multiplayer maps don't have path built by default. The mp-navigation PK3 file can be downloaded and installed in the main
directory, it adds navigation for all multiplayer maps, including multiplayer maps from Spearhead and Breakthrough.
