Problem Saving to Config File

I have some inventories and locations that I want to save to a config file, but I keep coming to an impass. When I save the information, it comes out like this;

Code:

    location: !!org.bukkit.Location
      pitch: 0.0
      world: !!org.bukkit.craftbukkit.v1_7_R1.CraftWorld
        PVP: true
        ambientSpawnLimit: 15
        animalSpawnLimit: 15
        autoSave: true
        difficulty: EASY
        environment: NORMAL
        fullTime: 144084
        keepSpawnInMemory: true
        monsterSpawnLimit: 70
        thunderDuration: 10150
        thundering: false
        time: 84
        waterAnimalSpawnLimit: 5
        weatherDuration: 65089
      x: 29.0
      y: 82.0
      yaw: 0.0
      z: 12.0

And when my program tries to read it back again, it fails with an error on the lines with two exclamation marks. The object seems to be serializing fine, but it's not saving the type correctly for some reason.

 

Maurdekye Objects that are not ConfiguerationSerlizable do not round trip when set through the Configuration API. Only objects which are ConfigurationSerializable, Strings, or Collections behave correctly.

 

Sagacious_Zed I've been able to save locations to a config file before; why aren't they working now / how can I get it to work?

 

Since I need to repeat myself. Objects that are not ConfigurationSerilizable do not round trip.

Objects that are not ConfigurationSerializable cannot be loaded by the configuration API. You must define your own object that is ConfigurationSerializable.

 

Sagacious_Zed So, just extend Location and implement ConfigurationSerializable?

 

Extending Location is not really advisable. On that note, an object is only ConfigurationSerializable if all the fields are ConfigurationSerilizable or String or Map or List or Set or a primitive.

 

Sagacious_Zed Then what is advisable? i'm not going to just walk away from this problem.

 

As I mentioned before "You must define your own object that is ConfigurationSerializable" Alternatively, you could encode location data as a String.

 

Sagacious_Zed "Location data as a string"... Think i'll try that.

Sagacious_Zed Also, why would they serialize, but not be able to deserialize? It doesn't make sense.

Try using these two methods

Code:java

public String serializeLoc(Location loc)
{
    return loc.getWorld().getName()+";"+loc.getX()+";"+loc.getY()+";"+loc.getZ()+";"+loc.getYaw()+";"+loc.getPitch();
}
 
public Location deserializeLoc(String loc)
{
    String[] st = loc.split(";");
 
    return new Location(Bukkit.getWorld(st[0]), Double.parseDouble(st[1]), Double.parseDouble(st[2]), Double.parseDouble(st[3]), Float.parseFloat(st[4]), Float.parseFloat(st[5]));
}

Than do

Code:

Location loc;
 
public void onEnable()
{
    loc = deserializeLoc(getConfig().getString("location"));
}
 
//Than to serialize it you do it anywhere you want
getConfig().set("location", serializeLoc(loc));
saveConfig();
