Personalities OXP

From Elite Wiki

Adds Oolite community personalities to your game



This OXP adds characters we all know and love from the Oolite Bulletin Boards to the Ooniverse. Each personality has some specific behaviour and communication patterns.

Notable Features

There is a 65% chance that you will meet one well-known personality when you either jump into a new system or launch from a main station. Some of them are traders or engage in asteroid mining, some of them are bounty hunters and will protect you in case a pirate attacks you—or attack you in case you are the pirate. Some will only engage Thargoids. And some greet you friendly first, but may try to make you one more step on their ELITE ladder if nobody else is looking. Their behaviour in combat varies, but expect all of them to be a little tougher than your average adversary.

A list of the personalities contained in the basic OXP can be found at the very bottom of its ReadMe, separated by enough whitespace. If you like to be surprised, don't scroll down.

Notes on Alnivel's update version 0.91 (2022)

Update of the original 10 personalities to work with newer versions of Oolite. Adds more options.

Notes on original version 0.9 (2009)


Personalities.oxp is a work in progress, and this version 0.9 is meant as a sneak preview, to give you a feeling what it looks like. It works as it is, but the final release may be different. Please help improving it by reporting bugs and strange or unexpected behaviour in its thread on the Oolite Bulletin Boards. Thanks very much!

Tales from the spacelanes...

I'd stopped off at a Space Bar for a quick beverage and perhaps news of a tempting contract in the vicinity and was rather pleased to find a valuable bounty target en route to my next destination. A few jumps later and I was sharing a system with potentially 8000 buckshee credits.

As the system was an Anarchy I had to splash a couple of pirate groups as I torused towards the station and just as I'd finished off the second group I received word that my target had been liquidated by someone else. Foul language may have been employed at this point.

Making the best of the situation I headed for the station to refuel and offload cargo. I dropped out of Torus a few seconds later when I encountered of all things Commander Wyvern in his Caddy Omega heading towards the witchpoint. Suddenly I had my suspicions of exactly who had snaffled my 8000Cr.

These suspicions were confirmed when shortly after passing Wyvern I encountered the remnants of my targets escorts. Clearly the meagre bounties on these peons had been beneath the notice of the mighty Caddy.

The moral of the story? No matter your combat rating or how high you might stand in the bounty hunters' guild, there's always someone in the eight charts with a sharper killer instinct than you. Travel safely friends and watch your six. Loxley (2011)


How do I add myself as a character?

Note: Take this instruction not as a “do it all yourself”, but rather as a reference in case you want to tweak something for yourself (or, well, do everything all yourself). You can always ask for help in the BB thread or even just leave a request there to be added.

You can do this either by modifying this OXP or by creating a separate one, but in any case, you will need at least basic knowledge of how to work on them. It is still preferable to be separate, but still choose as you like or can! A good starting point and reference would be OXP howto.

Make an entry about your ship in shipdata.plist

  1. As a base you can take a entry from the game files or OXP or, if your ship is from OXP, from its files.
  2. Adjust the parameters so that they correspond to the specs of your ship in the game. Pay special attention to:

Make sure that models, textures and shaders used be ship will be available not only for you

  1. Copy them to the appropriate folder of OXP.
  2. (Optional) It would be great if you change resource names, both filenames and references inside the models (.dat) and shipdata.plist, as this will help avoid conflicts.
Model files are just regular text files, same as shipdata.plist, so they can be opened in a any decent text editor. It might be a good idea to use search and replace - one Griff's Cobra model has more than 800 lines with the name of the texture.

(Optional) Add a character entry in characters.plist

If you're carrying an escape capsule with you, you should create this entry, or one day a complete stranger will escape the ship instead of you!

Example of such a entry:

"personalities-hesperus" = {
    bounty = 150; 
    name = "Captain Jack Hesperus"; 
    "random_seed" = "0 0 0 0 0 0"; 
    "short_description" = "a notorious, feline trumble dealer from Orrira"; 

Give your ship a personality (shipdata.plist)

  • name - shipname: charactername.
  • pilot - key of entry in characters.plist, for example,personalities-hesperus.
  • roles:
general role: personalities
occupation: personalities_cruiser (trader), personalities_privateer (pirate) or personalities_hunter (bounty hunter)
spawn options (several or even none may be specified):
personalities_galaxy_any - can appear in space or near main station in any galaxy
personalities_launcher_galaxy_any - can apear launching from main station in any galaxy (some ships are too big for that)
personalities_galaxy_0, personalities_launcher_galaxy_0 - similar to 'any' variant but limited only to the Galaxy One.
personalities_yourCharacterName - opional but useful for testing
  1. personalities personalities_privateer personalities_galaxy_any personalities_launcher_galaxy_any personalities_aodhan - pirate by name "Aodhan" that can appear in any galaxy both in space and via launch from main station,
  2. personalities personalities_hunter personalities_galaxy_7 personalities_launcher_galaxy_7 personalities_cwydion - bounty hunter by name "Gwydion" that can appear only in Galaxy Eight both in space and via launch from main station,
  3. personalities personalities_cruiser personalities_galaxy_0 ppersonalities_galaxy_1 personalities_galaxy_2 personalities_jameson - trader by name "Jameson" that can appear only in Galaxy One, Two and Three and only in space
  • ai_type and script - there are two options here: plist AI or priority AI
Plist AI - relatively obsolete, but more straightforward for making your own tweaks:
ai_type - personalitiesCruiserAI.plist, personalitiesHunterAI.plist or personalitiesPrivateerAI.plist
script - personalities-ship-script.js
Priority AI - available more communications and slightly better interaction with the environment:
ai_type - personalities-cruiserAI.js, personalities-hunterAI.js or personalities-privateerAI.js
script - personalities-priorityai-ship-script.js
You can also put in your own AI scripts, but then OXP will only decide when to add your personality, and you have to implement everything else yourself.

Customize behavior via script_info (shipdata.plist)

Add communication messages into description.plist

  1. Add entry of what types of messages are used, name below must be same as in script_info:
"personalities-name-messageTypes" = "attack attacked captured chatter dead flee jump kill launch witchspace"
  1. Add the comms themselves:
"personalities-name-attack" = ("Phrase to be sent when attack");
"personalities-name-attacked" = ("Either this phrase will be sent..", "or this one when ship attacked");
"personalities-name-chatter" = ("Also you can add...{pause: 5} some dramatic pauses!");
List of available message types
Comms key Full form (PriorityAI scripts) Notes
attack oolite_beginningAttack Commencing an attack, repetitive

Note: With PriorityAI scripts you can also use any standart comms key with or without oolite_ prefix:

"personalities-name-messageTypes" = "dockingWait oolite_selectedStation"; // In messageTypes entry types must be writen same as in descriptions key!
"personalities-name-dockingWait" = ("Complaints about tedious waiting for docking");
"personalities-name-oolite_selectedStation" = ("Phrase about going to check local ConStore");

If you have any questions or suggestions, don't hesitate to ask them in BB thread or send a PM to Alnivel.

How do I remove my own character?

  1. Open the shipdata.plist inside the "Config" folder.
  2. Look for the entry "personalities-<yourname>".
  3. Remove it completely OR Go to its "roles" key, and delete the roles with "personalities" and "personalities_launcher".

Version History

  • version 0.9.2 (October, 2022)
new AI scripts, most personalities now use them

fixed a bug in plistAI scripts that caused the ships themselves to never attack
pauses can be added to comms messages: "The message will be split{pause: 12}and the second half will be sent with specified delay"
appearance can be limited through the list of roles:
1) "personalities personalities_privateer personalities_galaxy_any personalities_launcher_galaxy_any personalities_aodhan" -

  • version 0.9.1 (September, 2022) by Alnivel
requires Oolite 1.90 (probably can work even on versions 1.82+, but not tested)
fixed several broken function calls

changed comms message using method, it now requires a description.plist entry to be defined in this format:
"personalities-<personality name>-messageTypes" = "<list of space separated message types>";
rewritten methods for the spawn of special ships, changing a probability of this spawns now easier
added method for adding role to appear on a specified condition, such as system id, after some event etc
