Prototype: Object
This class was added in Oolite test release 1.74.
SystemInfo objects provide information about a specific system.
Contents
Properties
coordinates
coordinates : Vector (read-only)
The coordinates of the system in light years. e.g. for Lave: (8, 34.6, 0). The z component is always zero.
e.g.
System.infoForSystem(galaxyNumber, 7).coordinates
returns the coordinates of the system with an ID numberr of 7 in the current galaxy. In the first galaxy that would be the Lave coordinates: (8, 34.6, 0).
galaxyID
galaxyID : Number (read/write nonnegative integer)
The ID number of the galaxy.
systemID
systemID : Number (read/write nonnegative integer)
The ID number of the system.
More properties
Additional to these properties you have access to many other system properties, using the same keys as planetinfo.plist. e.g.
System.info.description = "This is a dull planet."
sets the description of the current planet to "This is a dull planet."
Methods
distanceToSystem
function distanceToSystem(SystemInfo) : Number
Returns the distance in light year to the other SystemInfo.
routeToSystem
function routeToSystem(SystemInfo) [, "OPTIMIZED_BY_JUMPS" | "OPTIMIZED_BY_TIME"] : Dictionary
Returns a dictionary containing the route information to the other SystemInfo. The dictionary contains the array of system IDs that belong to the route found, the distance and the time corresponding to said route. Takes the optional parameter "OPTIMIZED_BY_JUMPS" or "OPTIMIZED_BY_TIME" to calculate least number of jumps or fastest transit time routes respectively. If the second parameter is omitted, "OPTIMIZED_BY_JUMPS" is implied.
systemsInRange
function systemsInRange(Number) : Array
Returns an array of SystemInfos in range. When no distance is defined, 7 is assumed.
Static methods
filteredSystems
function filteredSystems(this : Object, predicate : Function ) : Array of SystemInfo
A list of the SystemInfos for which predicate returns true.
Example:
SystemInfo.systemsInRange = function(range)
{
if (range === undefined)
{
range = 7;
}
var thisSystem = system.info;
return SystemInfo.filteredSystems(this, function(other)
{
return (other.systemID !== thisSystem.systemID) && (thisSystem.distanceToSystem(other) <= range);
});
}
