OXP
An OXP (Oolite eXpansion Pack) is an enhancement to the game Oolite. Typically, an OXP is downloaded as a ZIP file, which is expanded in Oolite's AddOns folder. The OXP itself takes the form of a folder, which Oolite scans when it is started. An OXP can be a new game object (such as a ship, space station or a moon) or a mission. OXPs can use all of the facilities of Oolite, including some that are not used in the standard, unexpanded game.
Downloading an OXP
Most OXPs can be found at The Oolite Satellite Resource Site
Installing an OXP
Unzip the OXP in the AddOns folder. This can be in a number of locations depending on the parent platform:
Macintosh: found in the folder that contains the Oolite application.
Linux: If the game was installed system-wide, it is in /usr/lib/Oolite/AddOns. If it was installed jsut for the currently logged in user, it will be in the user's home directory.
Win32: If the installable package was used (post Jan 06) then the AddOns folder needs to be created in C:\Programs Files\Oolite. Note that this applies if the default installation location is used. If the install location is changed then use the path to the Oolite folder that correspnds to your installation. If the GNUStep dedicated versions (pre-Jan 2006) is used, then the AddOns folder must be created in the oolite.app folder.
When you unzip the file, make sure that the OXP folder is in the AddOns directory - some zipped OXPs contain a top level folder with a readme file, and the actual OXP folder one level further down. If this is the case, move the folder with the '.oxp' extension up to the AddOns folder.
Caveats
If you purchase a ship that is an OXP ship and save the game, you will only be able to load that commander on a computer with that OXP installed. Oolite will give you an error instead of trying to load the commander.
Creating an OXP
It is intended to be easy to create expansion packs. With a few simple tools, a player can make small or big changes, and customize the gaming experience.
