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 and placed in Oolite's AddOns folder. The OXP itself is a folder which takes the form of the icon above, which Oolite scans when it is started. An OXP could be a new game object (such as a ship, space station or a moon), a mission, or a combination of several elements. OXPs can use all of the facilities of Oolite, including some that are not used in the standard, unexpanded game.

Downloading OXPs

Most OXPs are found at The Oolite Satellite Resource Site (see also the old CapnHack OoSat)

Not all OXPs are listed on the Oosat2 site (some can only be found on the Oosat1 site). If however a version of an OXP appears on both sites remember to use the version from the Oosat2 site. The versions of Spyhunter, Ionics and the Assassins Guild on Oosat1 contain bugs. The updated (bug fixed) versions of Spyhunter and Ionics can be found on Oosat2. The latest version of the Assassins Guild is now stored on the Wikki.

OXP authors are encouraged to use the Wikki to store their OXPs, in order that eventually all the OXPs will be in one place. If you scroll down to the bottom of this page, you will see a full list of OXPs and right at the bottom a list of OXP categories. If you follow the categories link you will be taken to the OXPs stored on the Wikki.

Installing an OXP

Unzip the OXP and place it in the folder named AddOns. Sometimes the zipped files contain several folders, make sure you only copy the folder -or file for Macintoshes- ending with .oxp into the AddOns folder. This folder is found in different locations, depending on the platform:

Mac OS X

Found in the folder that contains the Oolite application.

Troubleshooting: If you get an error saying "The item could not be moved because "AddOns" cannot be modified", that can happen if you weren't the user that installed Oolite. The solution is to put the OXP's of your choice in ~/Library/Application Support/Oolite/AddOns/ instead (you may need to create this folder). The error could also be triggered because you’re running from the disk image, you’ll need to copy the game somewhere else. Having done so, if you still get the error, use the Get Info command on the AddOns folder, open the Ownership & Permissions pane and check that it says You Can: Read & Write.

Linux

If the game was installed system-wide, it is in /usr/lib/Oolite/AddOns. If it was installed just for the currently logged in user, it will be in the user's home directory, in $HOME/.local/lib/Oolite/AddOns except Debian systems. Debian changes the folder locations to $HOME/.Oolite/Addons., $HOME/Library/Application Support/Oolite/AddOns/ and /usr/lib/GNUstep/System/Applications/AddOns. This, hopefully, solves many a Debian users dilemma of where to put the OXPs.

Windows

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.

After unzipping the file, make sure that it is the OXP folder that put into the AddOns directory - some zipped OXPs can contain a top level folder with a readMe file, and the actual OXP folder is a level further down. If this is the case, move the item with the .oxp extension into 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 as long as this OXP is installed in AddOns. If it's not, 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.
