Class ZoneGrid

java.lang.Object

com.simsilica.ethereal.zone.ZoneGrid

public class ZoneGrid
extends java.lang.Object

Can translate to/from integer-based grid coordinates and world real coordinates. Note: Zones are essentially 2 dimensional in the 'ground' plane, by JME convention: x, z

getZoneSize

public com.simsilica.mathd.Vec3i getZoneSize()

worldToZone

public com.simsilica.mathd.Vec3i worldToZone(double x,
                                             double y,

zoneToWorld

public com.simsilica.mathd.Vec3i zoneToWorld(int x,
                                             int y,

worldToKey

public ZoneKey worldToKey(com.simsilica.mathd.Vec3d pos)

worldToKey

public ZoneKey worldToKey(double x,
                          double y,
                          double z)

zoneToWorld

public com.simsilica.mathd.Vec3i zoneToWorld(ZoneKey key)

toLongId

public long toLongId(ZoneKey key)

Converts the x, y, z to a single long by masking each value and bit shifting. This effectively means the zone x,y,z values are limited to 2^21 (+/- 2^20) but that's probably ok for all reasonable implementations. It's over a million zones in every direction.

fromLongId

public ZoneKey fromLongId(long id)

main

public static void main(java.lang.String... args)

toString

public java.lang.String toString()
