accuracy
Used with missiles it has influence on tracking of target. Allowed values with missiles are between 0.0 and 10.0. When not defined, the system assings to the missile the accuracy value of 0.0, which corresponds to the standard missile tracking behaviour.
Used with NPC ships it enlarges the chance of shooting at greater distances. Value with NPC ships is between -5 and 10.
Example:
<key>accuracy</key> <integer>8</integer>
aft_eject_position
Determines the XYZ point on the model from which cargo is ejected.
Example:
<key>aft_eject_position</key> <string>0.0 -4.5 -23.0</string>
aft_weapon_type
Assigns the ship's laser. Any weapon type from the equipment.plist can be used (and WEAPON_NONE).
Example:
<key>aft_weapon_type</key> <string>WEAPON_BEAM_LASER</string>
ai_type
Assigns an AI to the entity. This may be a previously existing AI, or one custom made for the occasion.
Example:
<key>ai_type</key> <string>pirateAI.plist</string>
auto_ai
Introduced in version 1.69 to autoswitch ai to the appropriate one if a ship was added by a script in one of its standard roles like trader or pirate. See also the comment inside the autoAIMap.plist inside Oolite 1.69 or newer. When not defined it will be true by default. Defining auto_ai is only necessary when using one of the standard roles mentioned in the autoAIMap.plist for your ship. Example:
<key>auto_ai</key> <true/>
Starting with Oolite 1.73 also the populator will look at the auto_ai during system setup. When auto_ai is false the ship will keep the ai_type defined for the ship and not give it the default ai for that role.
beacon
A special feature for beacons and navigation aids. The string can be anything - the first letter is what's displayed in the advanced space compass.
Example:
<key>beacon</key> <string>X-code</string>
The following characters are known to be used as identifiers for stations and other fixed objects (listed with their respective OXPs):
A = Astromine (Commies) B = Black Monk Monastery (Black Monks) A Seedy Space Bar (Random Hits) Nemeanian Military Base (Assassins) C = CoachWhip hOopy Casino (Hoopy Casino) Pi-42 Con Store (Your Ad Here) F = Collective Zero-G Factory (Commies) Collective SLAPU (Commies) Imperial AstroFactory (Dictators) G = Griff Research Ltd Orbital Base (Assassins) GRS Buoy Factory (GRS Buoy Repair) H = Hacker Outpost (Anarchies) Deep Space Hoopy Hotel : Hades Branch (Assassins) L = The Link Base (Ionics) Deep Space Hoopy Hotel : Lernean Branch (Assassins) N = Main Station Beacon P = Tianve Pulsar Monitoring Station (Tianve) R = Rock Hermit (Rock Hermit Locator) Augeaian Orbital Repair Facility (Assassins) Rebel Outpost (Assassins) Q = Hesperides Wiseguy Way-Station (Assassins) S = Navy SecCom Station (Galactic Navy) Special Branch Orbital Headquarters (Assassins) T = Taranis Corporation HQ (Taranis) W = Witchpoint Buoy Z = Free Trade Zone (Free Trade Zone)
The following characters are known to be used for non-station objects that may appear anywhere:
H = Homing Beacon (ett Homing Beacon)
The following characters should not be assigned easily to stations or ships that are supposed to appear anywhere, because they are likely to be used for ships in other OXPs:
M = Mark T = Target V = Victim X = general marker + = general marker
bounty
Sets a Cr. reward on the NPC's head, and is bound to give it trouble with the law .
Example:
<key>bounty</key> <integer>50</integer>
cargo_carried
Determines the type of cargo carried as described in commodities and commodities.plist. Only one type can be specified.
Example:
<key>cargo_carried</key> <string>Gold</string>
cargo_type
Determines if object is indeed cargo (CARGO_RANDOM, CARGO_SLAVES, CARGO_THARGOID, CARGO_ALLOY, CARGO_MINERALS) or a ship, as below, which is not cargo. Only works for randomly generated cargopods. Works since Oolite 1.71 also for pods spawn by a script. Another notable type of cargo is the scripted item (CARGO_SCRIPTED_ITEM), as examplified by the cloacking device. Other cargo_types than the above mentioned won't work unless you use CARGO_CARRIED.
Example:
<key>cargo_type</key> <string>CARGO_NOT_CARGO</string>
In v1.63, more control of contents of barrels will be available through the CARGO_CARRIED string. (see also discussion)
Example:
<key>cargo_type</key> <string>CARGO_CARRIED</string> <key>cargo_carried</key> <string>4 Gold</string>
You can also specify the cargo of a ship. use "cargo_type" = CARGO_NOT_CARGO and define the contents of the barrels it will give with "cargo_carried"
Example:
<key>cargo_type</key> <string>CARGO_NOT_CARGO</string> <key>cargo_carried</key> <string>Computers</string>
cloak_passive
When true, any firing of laser will deactivate the cloak. (Added in oolite 1.73. False by default)
Example:
<key>cloak_passive</key> <true/>
conditions
Whit this option you can include an array of extra conditions when to add a ship. When the conditions are not met, the ship does not appear in a selection list by role. Useful when you have a standard ship like a trader that should only be added in certain systems.
Example:
<key>conditions</key> <array> <string>systemGovernment_number equal 3</string> <string>systemEconomy_number lessthan 4</string> </array>
custom_views
Will add the ability to display custom POVs of the player ship, in game toggled by pressing v.
This is an array with any number of entries, one for each view, each with:
- a view_description - giving a textual description of the view.
- a view_position - relative to the origin of the ship model.
- a view_orientation - this is a quaternion expressing a rotation from directly forwards.
- a weapon_facing - FORWARD, AFT, PORT or STARBOARD. The weapon that will fire when that view is selected.
The view_position is best chosen by selecting a facet, line or point in Wings and copying down the coordinates.
For the view_orientation you will probably need a calculator but the basic method is to choose a unit vector (x y z) as the axis for a rotation then calculate the four values W X Y and Z for the quaternion as follows:
W = the cosine of half the angle rotated about the axis xyz
X = the sine of half the angle rotated about xyz, multiplied by x
Y = the sine of half the angle rotated about xyz, multiplied by y
Z = the sine of half the angle rotated about xyz, multiplied by z
Four decimal places are probably enough accuracy for these values.
Example:
<key>custom_views</key> <array> <dict> <key>view_description</key> <string>External View - Aft</string> <key>view_position</key> <string>0.0 100.0 -173.21</string> <key>view_orientation</key> <string>0.966 -0.259 0.0 0.0</string> <key>weapon_facing</key> <string>FORWARD</string> </dict> <dict> <key>view_description</key> <string>Scoop camera</string> <key>view_position</key> <string>0.0 -38.3333 1.6666</string> <key>view_orientation</key> <string>1.0 0.0 0.0 0.0</string> <key>weapon_facing</key> <string>FORWARD</string> </dict> </array>
death_actions
Gives an opportunity to have a ship's death trigger one or a set of script_actions.
Example:
<key>death_actions</key> <array> <string>spawn: explosive_shrapnel 1</string> </array>
defense_ship
Gives an oportunity to designate a particular ship by name that will defend a station/carrier. When launched from a carrier the scanclass becomes that of the carrier.
Example:
<key>defense_ship</key> <string>my_defender</string>
defense_ship_role
Gives an oportunity to designate a particular (group of) ships that will defend a station/carrier. This has to be specified in the roles of the ship(s) that are assigned to defend. When launched from a carrier the scanclass becomes that of the carrier.
Example:
<key>defense_ship_role</key> <string>carrier_defenders</string>
density
This real value is used to calculate a ships total mass. Default is 1.0 (Introduced in version 1.69?)
Example:
<key>density</key> <real>1.5</real>
display_name
States the model's name as it will be known to the ID computer. By default this is the same as "name". Added for multilingual oolite.
Example:
<key>display_name</key> <string>ExampleShip Mark IX</string>
energy_recharge_rate
The rate at which energy is replenished. Stations are at 100, Adders at 2..
Example:
<key>energy_recharge_rate</key> <real>3.5</real>
escape_pod_model
With this entry ships can have custom escape pods. (starting from version 1.65) You have to specify the role of your custom escape pod (not its entry-name).
Example:
<key>escape_pod_model</key> <string>custom_pod</string>
escorts
Determines how many escorts an NPC shall have. Maximum is 16. In save systems Oolite may randomly decide to subtract escorts from the defined value.
Example:
<key>escorts</key> <integer>4</integer>
Warning: Ships with scanClass = CLASS_POLICE should always have escorts set to zero. Oolite will set this value here and add wingmans instead of escorts. Without special scripting escorts won't escort a mother with CLASS_POLICE.
escort-role
Assigns the specific ship type to be the escort, by the ship's role
Example:
<key>escort-role</key> <string>my_custom_escort_role</string>
Warning: Only usable since Oolite 1.71. It will use the AI file defined in shipdata for this escort and will not use any default escortAI. So make sure the summoned escort has an AI defined in its entry that is capable of supporting escorting.
escort-ship
Assigns the specific ship type to be the escort, by the ship's name.
Example:
<key>escort-ship</key> <string>cobramk1</string>
equipment_price_factor
Equipment price mask for dockables.
Example:
<key>equipment_price_factor</key> <real>4.5</real>
equivalent_tech_level
Sets shipyard tech level for dockables, different to the local system techlevel.
Example:
<key>equivalent_tech_level</key> <integer>1</integer>
exhaust
The XYZ position(s) of exhaust plume(s), and the XYZ of the plume shape, ergo
x y z width height length
x y z is the position relative to the origin of the main model.
width in metres, how wide a plume is on x axis.
height in metres, how tall a plume is on y axis.
length in metres, how long a plume is on z axis.
Below are 2 assigned plumes at coords 5, 0, -25 and -5, 0, -25, and each plume is 6 m wide, 4 m tall and m 10 long
Example:
<key>exhaust</key> <array> <string>5 0.0 -25 6.0 4.0 10.0</string> <string>-5 0.0 -25 6.0 4.0 10.0</string> </array>
extra_cargo
New in version 1.62rc3 Cargobay extension size can now be customised. This is the amount the cargo capacity increases when an extra cargobay is installed. Defauld value is 15. It is only used with player ships.
Example:
<key>extra_cargo</key> <integer>value</integer>
forward_weapon_type
Assigns the ship's laser. Any weapon type from the equipment.plist can be used (and WEAPON_NONE).
Example:
<key>forward_weapon_type</key> <string>WEAPON_BEAM_LASER</string>
frangible
Determines if eventual sub-entities are "loose". By default any given object is already frangible, so the use of this line must be to negate that. If set to false, the object plus subentities will be regarded as a single object. If set to true, sub entities can be destroyed seperately from the main object.
Example:
<key>frangible</key> <false/>
fragment_chance
Determines if a ship breaks apart into fragments. Default is set to YES.
Example:
<key>fragment_chance</key> <false/>
fuel
Determines an NPC ship's fuel storage, which will affect how it uses its Fuel Injectors.
Example:
<key>fuel</key> <integer>70</integer>
has_cloaking_device
Determines if a ship has a cloacking device installed. By chance factor, or true/false.
Example:
<key>has_cloaking_device</key> <real>0.5</real>
has_ecm
Determines if a ship has the E.C.M system installed. By chance factor, or true/false.
Example:
<key>has_ecm</key> <real>0.5</real>
or
<key>has_ecm</key> <false/>
has_energy_bomb
Determines if a ship has an energy bomb. If it has it might launch a mine with role "energy_bomb" as part of his fleeing behavior. currently the only build-in mine with this role is the q-bomb.
Example:
<key>has_energy_bomb</key> <false/>
has_escape_pod
Determines if a ship has an escape pod. Starting with version 1.65 ships can have multiple escape pods. has_escape_pod must than be a numeric value of 2 or higher.
Example:
<key>has_escape_pod</key> <false/>
has_fuel_injection
Determines if a ship has the witchdrive fuel injector.
Example:
<key>has_fuel_injection</key> <real>0.99</real>
has_military_jammer
Determines if a ship has a military jammer. Ships equipped with this item become invisible on the radar. Example:
<key>has_military_jammer</key> <real>0.75</real>
has_military_scanner_filter
Determines if a ship has a military jammer filter. Ships equipped with this item can see ships equipped with a military jammer on the radar. Example:
<key>has_military_scanner_filter</key> <real>0.50</real>
has_npc_traffic
Determines if a carrier has trader trafic. Default is no, but when set to YES traders will launch now and then just like stations do. Introduced in version 1.70
Example:
<key>has_npc_traffic</key> <true/>
has_scoop
Determines if a ship has a fuel/cargo scoop.
Example:
<key>has_scoop</key> <false/>
has_shield_booster
Determines if a ship has the shield booster. (enlarges max energy with 256)
Example:
<key>has_shield_booster</key> <real>0.80</real>
has_shield_enhancer
Determines if a ship has the coveted shield enhancer. (enlarges max energy with 256 and raises energy recharge rate with 1.5)
Example:
<key>has_shield_enhancer</key> <real>0.45</real>
hasShipyard
Determines if a station or carrier has a shipyard. By chance factor as number between 0 and 1, but it can also be an array of conditions. (It does not accept a boolean like the other fuzzy boolean keys)
Example:
<key>hasShipyard</key> <real>0.75<real/>
heat_insulation
This real number gives the amount of heat insulation of a ship. Default is 1.0 Only for NPC ships. Playes ships can have the equipment EQ_HEAT_SHIELDING with gives the player than a heat_insulation of 2.0
Example:
<key>heat_insulation</key> <real>2.0</real>
hud
Used for a playership, to assign another HUD than the default one.
Example:
<key>hud</key> <string>specialhud.plist</string>
hyperspace_motor_spin_time
Used for a playership to modify jump countdown time. Default = 15. (Added with Oolite 1.72)
Example:
<key>hyperspace_motor_spin_time</key> <integer>15</integer>
isCarrier
Added as a tag for making the model be considered a carrier or station. An alternative to including carrier or station among the roles. When present this key even overrules station/carrier settings with roles.
Example:
<key>isCarrier</key> <true/>
is_submunition
Key added for missiles with multiple warheads. When this key is set and the entity is spawn or fired by a missile, it inherits its parent as owner. This key must be set so the player will be awarded for a kill by submunition. (Key added in Oolite 1.72)
Example:
<key>is_submunition</key> <true/>
is_template
Set this to yes/<true/> for ships which are only used through like_ships and are not intended to be used directly. If your (otherwise working) OXP generates warnings about ships with no roles or model attribute, you probably need this. (Key added in Oolite 1.72)
Example:
<key>is_template</key> <true/>
laser_color
Determines a ship's laser colour.
In Oolite 1.69 and later, this is any colour specifier. In earlier versions, it must be a named colour. Also as of 1.69, the game requires laser colours to be reasonably bright; if the brightest colour component is less than 0.5, the colour will be brightened.
Example:
<key>laser_color</key> <string>cyanColor</string>
launch_actions
Triggers a script on the entity just after setup, also when called by spawn and addShip methods. Can be used to change to a custom AI, when a ship is generated by standard role. script_actions
Example: "role = trader" <key>launch_actions</key> <array> <string>setAITo: pirateAI.plist</string> </array>
like_ship
Allows a shipdata entry (of a ship with many matching characteristics to another) to be short and sweet. With like_ship you can reference to another existing shipdata entry, and then only specify the differences to the 'original'. It takes the unique entry-identifier as argument. Of course you have to make sure that the 'original' you are referring to actually exists, or Oolite won't be able to create your ship.
Works well together with the is_template-key.
Example:
<key>like_ship</key> <string>adder</string> <key>max_flight_speed</key> <real>700</real> <key>name</key> <string>Freak Turbo Adder</string>
likely_cargo
This is only used for ships with role asteroid and pirate. With asteroids it gives the likely number of boulders it breaks into. With pirates added by the System Populator: when lower than 16 it is the cargo, when higher than 15, it is changed in a random value between 0 and 15. This value is overridden by the actual scooped cargo if the pirate had scooped something.
Example:
<key>likely_cargo</key> <integer>2</integer>
materials
See Materials in Oolite.
max_cargo
Sets the ship's cargo limit. On explosion of trader ships added by the System Populator, 10% of this value is used as likely cargo. When the result is lower than 16 it is the cargo, when higher than 15, it is changed in a random value between 0 and 15.
Example:
<key>max_cargo</key> <integer>5</integer>
max_defense_ships
Designates how many ships a dockable entity (station, carrier) can launch in defense. See also Station Ships
Example:
<key>max_defense_ships</key> <integer>10</integer>
max_energy
Sets the ship's energy value.
Example:
<key>max_energy</key> <real>300</real>
max_flight_pitch
Sets pitch factor. Will usually range from a sluggish 0.6 to a very sensitive 3.0
Example:
<key>max_flight_pitch</key> <real>2.2</real>
max_flight_roll
Sets roll factor. Will usually range from 0.8 to 4.6.
Example:
<key>max_flight_roll</key> <real>4.2000000000000002</real>
max_flight_speed
Sets the model's top speed. Interceptors fly at 520 (0.52 LM), Shuttles at 80.
Example:
<key>max_flight_speed</key> <real>320</real>
max_flight_yaw
Sets yaw factor. Will usually range from a sluggish 0.6 to a very sensitive 3.0 When no value is defined it will use the same value as max_flight_pitch
Example:
<key>max_flight_yaw</key> <real>2.2</real>
max_missiles
Sets a ship's missile limit.
Example:
<key>max_missiles</key> <integer>1</integer>
max_police
Designates how many police or patrol ships a dockable entity (station, carrier) can launch. See also Station Ships
Example:
<key>max_police </key> <integer>10</integer>
max_scavengers
Designates how many scavengers or miners a dockable entity (station, carrier) can launch. See also Station Ships
Example:
<key>max_scavengers</key> <integer>10</integer>
missile_launch_position
Determines the XYZ point on the model from which a missile is launched.
Example:
<key>missile_launch_position</key> <string>0.0 -2.25 10.0</string>
missiles
Sets a ship's probable number of missiles.
Example:
<key>missiles</key> <integer>0</integer>
missile_role
Defines the entity that is launched as missile. Can specify a certain missile-type or any other ship-entity by role. Only applies to NPC's, player-ship dependacies must be defined in the shipyard.plist. If no missile_role is defined and a NPC ship launches a missile he most often chooses the default missile but sometimes chooses one at random from all ships with role missile inside one of the installed OXP's.
Example:
<key>missile_role</key> <string>thargon</string>
model
Assigns the entity's corresponding .dat file that will be found with the exact same name in the Models folder.
Example:
<key>model</key> <string>example_ship.dat</string>
name
States the model's name as it will be known to the ID computer.
Example:
<key>name</key> <string>ExampleShip Mark IX</string>
no_boulders
With older versions, scripted asteroids had no boulders by default. Starting with 1.70 all asteroids produce boulders when hit by a mining laser. no_boulders can overwrite this to emulate the old situation. By chance factor, or true/false.
Example:
<key>no_boulders</key> <true/>
pilot
Gives the ship a predefined pilot, defined in characters.plist. Can eject in pod, if available, and be captured.
Example:
<key>pilot</key> <string>constrictor-mission-thief</string>
port_dimensions
Defines the size of the docking port and takes 3 numbers. This key is generally of little use and can be skipped as it becomes overwritten by the size of the bounding box of the dock subentity.
Example:
<key>port_dimensions</key> <string>65 30 500</string>
port_radius
Defines the size of the docking port radius. Or more precise, this is the distance from the station centre to the port location. Default value is 500. This key is generally of little use and can be skipped as it will be overwritten by the real position of the dock subentity.
Example:
<key>port_radius</key> <string>500</string>
requires_docking_clearance
Sets the requirement for docking clearance. Default is false. See also DockingClearance
Example:
<key>requires_docking_clearance</key> </true>
roles
Assigns which role(s) the entity should have, that can correspond to one specific, exclusive use, or several.
The game engine constantly calls for generic roles to populate the universe. In the example below the ship in question will be considered twice as often (2.0) when a trader is called for, only one quarter as often (0.25) when looking for a hunter, and as often as any other pirate ships when looking for a pirate.
Example:
<key>roles</key> <string>hunter(0.25) trader(2.0) pirate</string>
or an exclusive role, simply:
<key>roles</key> <string>uniquely_named_role</string>
This has the benefit of being the only ship to be selected when a script calls for the uniquely_named_role ship.
An item from the commodities can also be named as a role, for when that commodity is floating in space and called upon, to be represented by a particular model.
Example:
<key>roles</key> <string>Gold</string>
Some roles are used by the game engine to populate systems, detect and define properties. (see also the System Populator) Such roles include 'thargoid', 'missile' and 'energybomb'. Externally used equipment also needs specific mention of role, for example EQ_*_MINE and EQ_*_MISSILE.
Extra care should be taken with using the words station or carrier as part of a role name. Don't do it! Even when these words are part of the role and the ship has no dock itself, it gives the ship station attributes. Other ships might even fruitless try to dock with it.
rotating
Given to a station when rotation is desired.
Example:
<key>rotating</key> <true/>
rotational_velocity
May be applied to a sub-entity, like the following entry to the subentity spines of the Weeviloid Hunter. Takes the form of quaternions. The following example enables rotation around the Z-axis.
Example:
<key>rotational_velocity</key> <string>0.707 0.0 0.0 0.707</string>
scanClass
Will alter the model's appearance on the IFF system. If this line is omitted, it will become by default a standard ship entity, appearing as yellow flag on the radar. There are other options.
- CLASS_BUOY
- CLASS_CARGO
- CLASS_MILITARY
- CLASS_MISSILE
- CLASS_POLICE
- CLASS_ROCK
- CLASS_STATION
- CLASS_THARGOID
Developer Note
Oolite uses scanClass internally to determine the behaviour of some ships (particularly with regard to who may shoot whom without incurring legal penatlties). Bear this in mind and don't allocate CLASS_POLICE or CLASS_THARGOID to ships lightly!
Example:
<key>scanClass</key> <string>CLASS_ROCK</string>
scanner_range
Sets a custom scanner range. Standard is 30km, thargoids have 50km. Only applies to NPCs.
scoop_position
Determines the XYZ point on the model from which cargo is scooped. (default is 0,0,0)
Example:
<key>scoop_position</key> <string>0.0 -4.5 -23.0</string>
script
Specifies a JavaScript script to attach to the ship. Ship scripts were introduced with Oolite test release 1.70, and are the preferred approach to scripting ships in new versions of Oolite.
script_info
A property list whose contents are available to JavaScript scripts, for whatever use they desire. It is exposed to JavaScript as the scriptInfo
property of Ship
objects.
script_actions
Gives an oportunity to insert events such as in script.plist, to involve a specific shipdata entity. As seen in the following example, this particular object checks if Player has a cloaking device, and if not, will award it. Should Player already have it, the gift will be in gold. See also scripts within shipdata for more detailled info.
Example:
<key>script_actions</key> <array> <string>debugOn</string> <string>testForEquipment: EQ_CLOAKING_DEVICE</string> <dict> <key>conditions</key> <array> <string>foundEquipment_bool equal NO</string> </array> <key>do</key> <array> <string>awardEquipment: EQ_CLOAKING_DEVICE</string> </array> <key>else</key> <array> <string>awardCargo: 100 Gold</string> </array> </dict> <string>debugOff</string> </array>
setup_actions
Arranges a process that may be necessary for some objects, like ball turrets.
Example:
<key>setup_actions</key> <array> <string>initialiseTurret</string> </array>
shaders
The shaders dictionary has the same structure as the materials dictionary. When shaders are available, the contents of the shaders dictionary are used in preference to those in materials. If shaders are not available, the shaders dictionary is ignored.
smooth
Determines if the model will use glLightModel(GL_FLAT) or glLightModel(GL_SMOOTH).
If true, then lighting effects will be interpolated across the polygons of the model, giving a more 'rounded' effect.
Asteroids, Boulders and Splinters use this effect as do some other models.
Example:
<key>smooth</key> <true/>
spawn
The spawn directory is only used when a ship is added with the command: "spawnShip: shipname". This command only allows to add one ship by name (not role!). The position and orientation are taken from a spawn directory that describes the position it is placed and the position it is looking at.
Example
<key>spawn</key> <dict> <key>facing_position</key> <string>spu 0 0 0</string> <key>position</key> <string>wpu 0 0 0.2</string> </dict>
subentities
Can assign other objects, lights and turrets, to be associated with the model, fixed to a relative position. The first three numbers are XYZ positions, however, controlling positioning of enslaved objects is done by means of quaternions.
Lights follow their own recipe.
*FLASHER* x y z hue speed offset size
x y z is the position relative to the origin of the main model.
hue describes the colour of the light as an angle on a colour wheel.(0DEG = red =360DEG)
speed describes how fast the light pulses (on a sine wave) in Hertz (at 0 the light is constantly lit)
offset is the offset to the sine wave (0..1) to time-shift each light
size is the size of the light's corona in metres
Example:
<key>subentities</key> <array> <string>mySubEntity 0 -5 10 1 0 0 0</string> <string>*FLASHER* 0 5.5 10 30.0 1 0.0 12</string> </array>
note: armed subentities always fire along their Z-axis. When rotating along the Z(t=0)-axis.
track_contacts
Tracks the movement of the ship and sends a "CLOSE CONTACT" message to other ship AI's. It uses a time consuming tracking, so only set to true when actually used.
Example:
<key>track_contacts</key> <true/>
throw_sparks
Each new ship should start in seemingly good operating condition, unless specifically told not to. (Added with oolite 1.73, false by default)
Example:
<key>throw_sparks</key> <true/>
thrust
Gives the entity an 'inertia' value, translating size and speed into a form of velocity. 0 for rocks and cargo, 50 for a very fast ship, 100 for a station.
Example:
<key>thrust</key> <real>25</real>
unpiloted
Used to designate items that will never have a pilot, thus never turn aggressive and never eject a pod.
Example:
<key>unpiloted</key> <true/>
view_position_..
Sets the ship's 4 point-of-view positions in XYZ relative to the model.
Example:
<key>view_position_aft</key> <string>0.0 5.0 -20.0</string> <key>view_position_forward</key> <string>0.0 1.9375 5.0</string> <key>view_position_port</key> <string>-11.85 2.825 -3.5</string> <key>view_position_starboard</key> <string>11.85 2.825 -3.5</string>
weapon_energy
This setting works differently depending on the type of entity it's used for:
Missiles. Changes the damage inflicted by the missile. Any value accepted.
Example:
<key>weapon_energy</key> <real>180</real>
NPC ships. Changes the forward weapon damage to a value different to the default one. Values higher than 50 will be ignored.
Default values are: WEAPON_PLASMA_CANNON = 6.0; WEAPON_PULSE_LASER = 15.0; WEAPON_BEAM_LASER = 15.0; WEAPON_MINING_LASER = 50.0; WEAPON_THARGOID_LASER = 12.5; WEAPON_MILITARY_LASER = 23.0
Example:
<key>weapon_energy</key> <real>17</real>
N.B. It does not have any effect on player ships.
weapon_offset
Used to change the offsetpoint of a plasma cannon. Removed after version 1.65
Example:
<key>weapon_offset_x</key> <real>10</real>
weapon_position_..
Plots the 'gunmouth' points of the model's 4 potential lasers.
Example:
<key>weapon_position_aft</key> <string>0.0 -5.0 -20.0</string> <key>weapon_position_forward</key> <string>0.0 0.0417 16.6667</string> <key>weapon_position_port</key> <string>-13.75 -2.0625 -1.875</string> <key>weapon_position_starboard</key> <string>13.75 -2.0625 -1.875</string>
