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.
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.
Methods
distanceToSystem
function distanceToSystem(SystenInfo) : Number
Returns the distance in light year to the other SystemInfo.
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 !== thisSystem) && (thisSystem.distanceToSystem(other) <= range);
});
}
