Oolite JavaScript Reference: System

Prototype: Object
Subtypes: none

The System class represents the current system. There is always one System object, available through the global propery system.

Attempts to change system properties are ignored in interstellar space (i.e., the place you end up in after a witchspace malfunction).

Methods

addMoon

void addMoon(planetInfoKey)

Adds a moon to the system, using the specified entry in planetinfo.plist. A moon is the same as a planet, except that it has no atmosphere. (See also: addPlanet())

addPlanet

void addPlanet(planetInfoKey)

Adds a planet to the system, using the specified entry in planetinfo.plist. (See also: addMoon())

countShipsWithRole

integer countShipsWithRole(role)

Returns the number of ships with the specified role in the system; equivalent to checkForShips: in plist scripts. (To do: array shipsWithRole(role))

legacy_addShips etc.

void legacy_addShips(role, number)
void legacy_addSystemShips(role, number, position)
void legacy_addShipsAt(role, number, coordscheme, x, y, z)
void legacy_addShipsAtPrecisely(role, number, coordscheme, x, y, z)
void legacy_addShipsWithinRadius(role, number, coordScheme, x, y, z, radius)
void legacy_spawn(role, number)
void legacy_spawnShip(shipDataKey)

Various ways of causing ships to appear. Each of these corresponds to a legacy scripting method. A new, more flexible addShips() function will supersede all of them.

sendAllShipsAway

void sendAllShipsAway()

Makes all ships hyperspace out of the system.

setSunNova

void setSunNova(secondsUntilNova)

Sets the system’s sun to go nova after the specified time interval. Time is specified in game real time.
