API:Vessel

From Kerbal Space Program Wiki
Jump to: navigation, search

A Vessel represents a ship, or a piece of debris that was once part of a ship. You can access the vessel that your Part is part of with this.vessel. Particularly useful members are vessel.orbit, which gives your orbit, and vessel.mainBody, which gives CelestialBody whose influence you are currently under.

Vessel Class

Inherits Implements
MonoBehaviour
  • IShipconstruct
  • ITargetable
  • IDiscoverable

Vessels define individual ships in flight. They work essentially as a header for the set of parts that make up the ship.

NOTE: this value is calculated based on smoothed acceleration, so it isn't completely accurate. It will also change as the vessel's mass is reduced as fuel burns away. (it does get pretty accurate after burning for a few seconds)
