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. On the Macintosh, this is found in the folder that contains the Oolite application. On Linux, if the game was installed system-wide, it is in /usr/lib/Oolite/AddOns if installed system wide, or in the user's home directory if installed just for the user who downloaded the game. 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.
