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. On the Mac the OXP itself is a folder which takes the form of the icon shown here. On Windows the OXP appears as a normal folder ending ".oxp". 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. Oolite will only read an OXP if you place the .oxp folder in Oolite's AddOns folder.

Downloading OXPs

On this page you will find download links to all the OXPs. Most OXPs can also be found at The Oolite Satellite Resource Site or the older Captain Hack OoSat Site).

Please note however that neither of these sites have been updated for a long time, nor will they be. All updating is now done on this page of the Wiki, so you should use the link shown on this page to get the latest version of the OXP. For example, the versions of Assassins.oxp, Ionics.oxp and Spyhunter.oxp on the Captain Hack site are old versions (and contain bugs). The links on this page will take you to the latest versions.

The download will create a .ZIP file. Unzip it and a new folder will appear. Open this folder and you will see a folder ending .oxp and usually a README file. Move the folder ending .oxp into the Oolite AddOns folder. Next time you load up Oolite the new features added by the OXP will be added to the game. Do read the README file, as this will tell you what the OXP does.

Below you will see a table giving download links to all the OXPs set out in alphabetical order. The links in the next column will take you to Wiki Pages giving information on ships or stations added by the OXP. Many of the Mission OXPs will contain lots of other ships, stations or weapons that are not listed here. The Wiki only gives information on the Ships listed in the galaxy wide "Jane's Spacecraft". Many military, criminal and corporate powers do not make information on the craft they build or use available to the galactic public! Listed below the table are all the OXPs broken down by category.

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.
