The Entity class represents an object in the game universe – Vessels, Stations and CelestialBodys are common types of entity. Note that these more specific types have additional properties and methods.
Contents
Universal IDs
Every Entity has an unique universal ID. All Oolite-provided functions which take an Entity as an argument may also be passed an integer representing the Entity’s ID.
Properties
ID
ID [read-only integer]
The universal ID of the entity.
position
position [read-write Vector]
The position of the entity in system co-ordinates.
velocity
velocity [read-write Vector]
The velocity of the entity in system units (nominal metres) per second.
speed
speed [read-write double]
The speed of the entity in system units (nominal metres) per second.
entity.speed() is equivalent to entity.velocity().magnitude().
orientation
orientation [read-write Quaternion]
The spacial orientation of the entity.
heading
heading [read-only Vector]
The heading of the entity. This is equivalent to orientation, but ignoring the axial twist component (roll in the case of a ship).
status
status [read-only string]
The current status of the entity (such as “STATUS_IN_FLIGHT” and “STATUS_BEING_SCOOPED”).
scanClass
scanClass [read-only string]
The current scan class of the entity (such as “CLASS_NEUTRAL” and “CLASS_CARGO”).
mass
mass [read-only double]
The mass of the entity. Currently, this is directly proportional to the volume.
owner
owner [read-only Entity]
The entity which owns this one. In the case of a subentity, the entity to which it is attached. In the case of a defense ship, the station it belongs to. In the case of a missile, the ship that launched it. There may be other uses.
energy
energy [read-write double]
The entity’s total energy; ranges from 0 to maxEnergy.
maxEnergy
maxEnergy [read-only double]
The highest permissible value of energy.
