Oolite JavaScript Reference: Ship script event handlers

This page provides a list of event handlers which can be implemented by JavaScript scripts for Oolite.

Ship scripts are linked to Oolite either using the appropriate shipdata.plist setting or via javascript using ship.setScript and are only active when the ship is present. More than one ship can be assigned the same ship script. Each ship will create its own separate copy of the script, each one independent from the others.

The list of event handlers will change from version to version (usually additions of extra handlers). For this reason, any variables or functions you create as this.variable should have a name beginning with '_' or '$' - e.g. this._variable or this.$variable - to avoid potential conflicts with future event handlers.

Note that a ship script event which affects the player ship (therefore not those marked NPC only, station only, etc.) will also appear as a world script event.

In Oolite 1.79 onwards, each ship has two scripts: the "ship script" as in previous versions (ship.script) and an AI script (ship.AIScript) which manages Javascript-based AI. The former is intended for constant events related to the ship itself, and the latter is intended for event handling which varies based on what the ship is currently doing. Both scripts receive all events which do not expect a return value. Events expecting a return value are sent to the ship script only.

Docking

shipWillDockWithStation

The shipWillDockWithStation handler is called at the beginning of the docking tunnel effect.

this.shipWillDockWithStation = function(station)
{
     // Your code here
}

At this moment "ship.dockedStation == nil", "ship.status == STATUS_DOCKING"

shipDockedWithStation

The shipDockedWithStation handler is called at the end of the docking tunnel effect.

this.shipDockedWithStation = function(station)
{
     // Your code here
}

At this moment "ship.dockedStation == the station", "ship.status == STATUS_DOCKED" and "gui_screen" is either GUI_SCREEN_STATUS or GUI_SCREEN_REPORT. However, any identical handler from an other oxp could have changed those values. Never count on it but double check when important.

shipWillLaunchFromStation

This handler was added for npc ships with test release 1.75, before it was a worldScript only handler.

The shipWillLaunchFromStation handler is called for ship scripts on ship creation, before the shipSpawned event.

this.shipWillLaunchFromStation = function(station)
{
     // Your code here
}

shipLaunchedFromStation

The shipLaunchedFromStation handler is called at the end of the launch tract, when the ship has clearly left the station and AI updating begins.

this.shipLaunchedFromStation = function(station)

{
     // Your code here
}

shipAIFrustrated

This method was added in Oolite test release 1.79. The shipAIFrustrated handler is called when the ship's low-level behaviour is unable to achieve the desired result (e.g. a performFlee request is not getting further from the target). A short string describing the context of the frustration is passed as a parameter.

this.shipAIFrustrated = function(context)
{
     // Your code here
}

shipBountyChanged

This method was added in Oolite test release 1.77.

The shipBountyChanged handler is sent when an event tries to change the bounty level of the ship. delta may be zero, positive or negative. reason is a string that may either contain a standard value or a custom value set by an OXP. The standard values are:

• setup actions: Bounty level settings in the system populator or as a side effect of launching a ship from a station with a particular role.

this.shipBountyChanged = function(delta,reason)
{
     // Your code here
}

shipCloseContact

The shipCloseContact handler is sent when approaching otherShip and when "track_contacts" in shipData is true.

this.shipCloseContact = function(otherShip)
{
     // Your code here
}

shipCollided

The shipCollided handler is sent after a collision with otherShip.

this.shipCollided = function(otherShip)
{
     // Your code here
}

shipNowFacingDestination

This method was added in Oolite test release 1.79. The shipNowFacingDestination handler is called when the ship is facing its destination during certain flight behaviours.

this.shipNowFacingDestination = function()
{
     // Your code here
}

shipReachedEndPoint

The shipReachedEndPoint handler is sent after reaching the last navigation point when in mode performFlyRacepoints.

shipReachedEndPoint = function()
{
     // Your code here
}

shipReachedNavPoint

The shipReachedNavPoint handler is sent after reaching a navigation point when in mode performFlyRacepoints.

this.shipReachedNavPoint = function()
{
     // Your code here
}

shipScoopedOther

The shipScoopedOther handler is called when a ship scoops scripted_cargo. ("cargo_type" = CARGO_SCRIPTED_ITEM) Other cargo, even scooping escapepods, doesn't trigger a handler.
The scooped item is transferred as argument. The scooped cargo itselfs gets the handler: shipWasScooped with the scooper as argument. Starting with Oolite 1.77 this handler will fire on every scooped object.

this.shipScoopedOther = function(whom)
{
     // Your code here
}

shipLaunchedEscapePod

The shipLaunchedEscapePod handler is called when the pilot bails out. This will be followed by a shipWillDockWithStation()/shipDockedWithStation() pair after a few seconds when it is the player that is ejecting.

this.shipLaunchedEscapePod = function(escapepod, passengers)
{
     // Your code here
}

escapepod contains the main pod with the pilot. passengers will be added with Oolite 1.77 and is an array with passenger pods for those ships that have more than one escape-capsule defined.

NPC only

aiAwoken

This method was added in Oolite test release 1.79. This is sent to the ship periodically when ship.AIScriptWakeTime passes. One of the actions of this handler should be to cause a new wake time to be set. It is received by both the ship script and the AI script but usually only of interest to the latter.

aiStarted

This method was added in Oolite test release 1.79. This is sent to the ship when a new Javascript-based AI is loaded. The AI Script should then use it to do initialisation. The ship script can usually ignore it.

coordinatesForEscortPosition

The coordinatesForEscortPosition handler fires whenever the game engine wishes to know the positions of escorts relative to their group leader, and fires in the group leader's ship script at that time. It is given two parameters: the number of the escort, and the maximum number of escorts the group leader might have (which is not necessarily the number of escorts it currently has, of course). Unlike most ship script handlers, which return void, this handler is required to return a Vector (or a value equivalent to a Vector) describing the relative position of the escort to the mothership.

coordinatesForEscortPosition = function(num,max)
{
   // Your code here
   return escort_position;
}

The escort position is relative to the mothership, and in the mothership's coordinate system. For example, to place an escort 500m to the right of the mothership, return new Vector(500, 0, 0);. You are responsible for ensuring that there is sufficient space between the escorts and the mothership, and between any pair of escorts, or they will spend most of their time trying to avoid collisions with each other. If you intend to use the same ship script on several ships of varying sizes, you may wish to include the mothership's collisionRadius in the calculations.

Placing escorts directly ahead of the mothership (e.g. new Vector(0, 0, 500);) or too close to the mothership will trigger collision warnings for the mothership, making it difficult to maintain level flight for any significant time.

entityDestroyed

The entityDestroyed handler fires immediately after the ship becomes invalid, regardless of the reason, except when the game restarts. This is the best place for all kind of 'clean-up' code, for example stopping Timers associated with the ship script. (Added with Oolite 1.75.1)

entityDestroyed = function()
{
     // Your code here
}

escortAccepted

The escortAccepted handler is called when a mother ship accepts this ship as an escort. The mothership simultaneously gets a shipAcceptedEscort event.

this.escortAccepted = function(mothership)
{
     // Your code here
}

escortDock

The escortDock handler is called by a mother ships that uses the AI command: dockEscorts. Escorts are instructed to change AI into dockingAI.plist and enter the ABORT state of this AI after a certain delay. Than this event is send to all his escorts, each with a different delay with 3 seconds spacing.

this.escortDock = function(delay)
{
     // Your code here
}

escortRejected

This method was added in Oolite test release 1.79. The escortRejected handler is called when a mother ship rejects this ship as an escort.

this.escortRejected = function(mothership)
{
     // Your code here
}

offenceCommittedNearby

The offenceCommittedNearby handler is only send to police ships in scanner range of a hostile action. It transfers the attacker and the victim to the police vessel.

this.offenceCommittedNearby = function(attacker, victim)
{
     // Your code here
}

scriptedAI

This method was added in Oolite test release 1.77.

The scriptedAI handler is called each frame while the ship's AI is in "performScriptedAI" or "performScriptedAttackAI" mode. It must return an object defining the ship's flight parameters. The delta parameter is the length of the current frame in seconds. More information on using this functionality

this.scriptedAI = function(delta)
{
  // Your code here
  return flightParameters;
}

shipAcceptedEscort

The shipAcceptedEscort handler is called when this ship accepts a new ship as an escort. The escort simultaneously gets a escortAccepted event.

this.shipAcceptedEscort = function(newEscort)
{
     // Your code here
}

shipLandedOnPlanet

The shipLandedOnPlanet handler is called for ships landing on a planet. It transfers the planet parameter. (Will be added with Oolite 1.77)

shipLandedOnPlanet = function(planet)
{
     // Your code here
}

shipRemoved

The shipRemoved handler is called for ships removed by script. It transfers the suppressDeathEvent parameter so the script knows if there will also follow a shipDied() event.

shipRemoved = function(suppressDeathEvent)
{
     // Your code here
}

shipSpawned

The shipSpawned handler is called for newly added ships. It does not trigger on adding but on the first update after adding. On a witchspace jump it means that first all ships are added to the system, then afterwards all the shipSpawned() events are triggered. Note that this is not called for subentities - if subentities need specific set up running, this must be called from the main ship's handler.

this.shipSpawned = function()
{
     // Your code here
}

spawnedAsEscort

The spawnedAsEscort handler is called for newly added escort ships. It does trigger on adding the ship and before the shipSpawned() handlers is activated. It has the mothership as argument.

this.spawnedAsEscort = function(mother)
{
     // Your code here
}

shipWasDumped

The shipWasDumped handler is sent to the cargopod when a ship jettisons it. The dumping ship is transferred as the argument.

this.shipWasScooped = function(dumper)
{
     // Your code here
}

shipWasScooped

The shipWasScooped handler is send to the cargopod when a ship scoops scripted_cargo. ("cargo_type" = CARGO_SCRIPTED_ITEM) The scooper is transferred as argument. The scooper itself gets a trigger on the handler shipScoopedOther.

this.shipWasScooped = function(scooper)
{
     // Your code here
}

Stations only

alertConditionChanged

The alertConditionChanged handler is called when a station's alert status (Station.alertCondition) changes. Only the player and stations have an alert condition. The equivalent player event is handled inside world scripts.

this.alertConditionChanged = function(newCondition, oldCondition)
{
     // Your code here
}

otherShipDocked

The otherShipDocked handler is called with a station script only, when an ship docks. It has the docked ship as argument.

this.otherShipDocked = function(whom)
{
     // Your code here
}

stationDockingQueuesAreEmpty

This method was added in Oolite test release 1.79. The stationDockingQueuesAreEmpty handler is called when the last ship in the queues docks with the station (or gives up docking and leaves).

this.stationDockingQueuesAreEmpty = function()
{
     // Your code here
}

stationLaunchedShip

The stationLaunchedShip handler is called with a station script only, when a ship launches. It has the launched ship as argument.

this.stationLaunchedShip = function(whom)
{
     // Your code here
}

stationAcceptedDockingRequest

This method was added in Oolite test release 1.81. The stationReceivedDockingRequest handler is called when a ship has requested docking clearance and has been allocated a dock. Due to the way in which docking clearance works, this is likely to be called several times for the same ship as it moves through the docking sequence.

this.stationReceivedDockingRequest = function(whom)
{
     // Your code here
}

stationReceivedDockingRequest

This method was added in Oolite test release 1.81. The stationReceivedDockingRequest handler is called when a ship requests docking clearance. The ship requesting is passed as a parameter. This is often necessary for carriers which will need to come to a stop before ships can dock with them. Due to the way in which docking clearance works, this is likely to be called several times for the same ship as it moves through the docking sequence.

this.stationReceivedDockingRequest = function(whom)
{
     // Your code here
}

(note: a handler by this name was present in 1.79 and 1.80, but was called at the wrong time and should not be used. Set a minimum version of 1.81 if you use this event handler)

willOpenDockingPortFor

This method was added in Oolite test release 1.77.

The willOpenDockingPortFor handler is called with a station script only, when a ship requests docking, in cases where a dock is set to generally disallow docking (i.e. allowsDocking is false). It returns a Boolean:

• if it returns false (or this function isn't defined), this dock will not be opened later for the requesting ship, and it should not try again.
• if it returns true, this dock will be opened later for the requesting ship, and it should try again later if it cannot find another suitable dock on this station.

The handler is passed the identity of the dock and the requesting ship

this.willOpenDockingPortFor = function(dock, ship)
{
     // Your code here
     return allow;
}

Docks Only

This method was added in Oolite test release 1.77.

acceptDockingRequestFrom

This method was added in Oolite test release 1.77.

The acceptDockingRequestFrom handler is called when a ship is looking for docking clearance from the station, and is considering this dock. To get as far as calling this handler, the dock must have allowsDocking true, and be large enough to physically fit the ship.

It returns a boolean: true to accept the request (which, depending on docking queue lengths will not necessarily mean that this dock is the one that the ship heads for), and false to reject the request. 'true' is assumed if this handler is not defined.

This handler may be called multiple times for the same ship if the ship is having difficulty finding a suitable docking queue.

this.acceptDockingRequestFrom = function(ship)
{
     // Your code here
     return allow;
}

acceptLaunchingRequestFrom

This method was added in Oolite test release 1.77.

The acceptLaunchingRequestFrom handler is called when a ship is looking for launching clearance from the station, and is considering this dock. To get as far as calling this handler, the dock must have allowsLaunching true, and be large enough to physically fit the ship (unless the ship is the player).

It returns a boolean: true to accept the request (which, depending on launching queue lengths will not necessarily mean that this dock is the one that the ship uses), and false to reject the request. 'true' is assumed if this handler is not defined.

this.acceptLaunchingRequestFrom = function(ship)
{
     // Your code here
     return allow;
}

Missing Events

All initially planned events have a corresponding event handler in v1.74.

If there are other events you would like to be able to respond to, please write a request on the forum.
