为了使Location
可序列化,我建议使用此类。我自己写的,只是请求你在代码中给我信用。
package com.github.JamesNorris.Class;
import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;
import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.Server;
import org.bukkit.World;
/**
* The class that allows location to be serialized, and be used
* in a file. This class should not be changed, otherwise it
* will not work for older files.

public final class SerializableLocation implements Serializable {
private static final long serialVersionUID = 8650311534439769069L;
private final String world;
private final String uuid;
private final double x, y, z;
private final float yaw, pitch;
private transient Location loc;
/**
* Creates a new SerializableLocation instance of any org.bukkit.Location.
*
* @param l
*/
public SerializableLocation(Location l) {
this.world = l.getWorld().getName();
this.uuid = l.getWorld().getUID().toString();
this.x = l.getX();
this.y = l.getY();
this.z = l.getZ();
this.yaw = l.getYaw();
this.pitch = l.getPitch();
}
/**
* Gets the org.bukkit.Location back from any SerializableLocation.
*
* @param l
* @return
*/
public static Location returnLocation(SerializableLocation l) {
float pitch = l.pitch;
float yaw = l.yaw;
double x = l.x;
double y = l.y;
double z = l.z;
World world = Bukkit.getWorld(l.world);
Location location = new Location(world, x, y, z, yaw, pitch);
return location;
}
// FROM HERE ON NEEDS DOC NOTES
public SerializableLocation(Map<String, Object> map) {
this.world = (String) map.get("world");
this.uuid = (String) map.get("uuid");
this.x = (Double) map.get("x");
this.y = (Double) map.get("y");
this.z = (Double) map.get("z");
this.yaw = ((Float) map.get("yaw")).floatValue();
this.pitch = ((Float) map.get("pitch")).floatValue();
}
public final Map<String, Object> serialize() {
Map<String, Object> map = new HashMap<String, Object>();
map.put("world", this.world);
map.put("uuid", this.uuid);
map.put("x", this.x);
map.put("y", this.y);
map.put("z", this.z);
map.put("yaw", this.yaw);
map.put("pitch", this.pitch);
return map;
}
public final Location getLocation(Server server) {
if (loc == null) {
World world = server.getWorld(this.uuid);
if (world == null) {
world = server.getWorld(this.world);
}
loc = new Location(world, x, y, z, yaw, pitch);
}
return loc;
}
}
现在只需执行以下操作:
SerializableLocation loc = new SerializableLocation(LOCATION);
这是必需的原因是因为Location
contains world
、x
、y
、和z
,其中不可序列化。yaw
pitch
world
