Saving Location to a file from a hashmap?

I've tried in many ways but im stuck i can just save an arraylist but not a hashmap and i realy need help doing this.
Thanks for looking at this

You will have to store it as raw data type, eg int's/double's and Strings and then parse it yourself.

Eg

Code:java

 
Location loc;
String savedLoc = loc.getWorld.getName() + ":" + loc.getX() + ":" + loc.getY() + ":" + loc.getZ() + ";"
 

In this case I am using the colon : as the delimeter and the semi colon ; as the end tag. You can then parse these locations yourself by using String.split(":") and then taking the args from that array and passing them into the location constructor.

Location loc = new Location(world, x, y, z);

Alternatively you may want to use my serializable Location class from Sync https://github.com/Adamki11s/Sync/blob/master/src/couk/Adamki11s/IO/Serializable/SyncLocation.java

If you do use that class then please credit me.

 

Or just use this: http://wiki.bukkit.org/Plugin_Tutorial#Saving.2FLoading_a_HashMap

 

That wouldn't work. The standard Bukkit Location class cannot be serialized.

 

Then make a custom location class it's best that way too since the Bukkit Location has references to worlds and stuff that shouldn't be stored... AFAIK.

 

But i have one problem. How do i save the hashmap itself im pretty new to coding and don't know all about everything so it would be of great help. Could u just not save a hashmap in an arraylist or something cuz i looked at the class u linked and come up with that i have no clue what's in it. Sorry for my noobness.
Thank you for helping me.

I use this object whenever i want to save a location

Code:java

 
import java.io.Serializable;
 
import org.bukkit.Bukkit;
import org.bukkit.Location;
 
public class LocationPack implements Serializable {
    private static final long serialVersionUID = -8100514952085724461L;
 
    private final String worldname;
    private final double x;
    private final double y;
    private final double z;
 
    public LocationPack(Location location) {
        this.worldname = location.getWorld().getName();
        this.x = location.getX();
        this.y = location.getY();
        this.z = location.getZ();
    }
 
    public Location unpack() {
        Location location = new Location(Bukkit.getWorld(this.worldname), this.x, this.y, this.z);
 
        return location;
    }
}

 

Yeah that's what I did in Sync. I was suggesting he either copy it or make something similar lol
