Getting player location and saving

hi i've never made a plugin that really needed to store information for a long period of time, but im trying to make a command that will save the players current location and be able to use that location later.

should i have the plugin write the cords to a config? I guess i'm just trying to ask what is the best way to do this

 

Yes, you should write the player's coordinates to a configuration file or you could use a hashmap but the hashmap will be cleared if the server is reloaded.

Config method;

Code:java

// Save to config
plugin.getConfig.set(player.getUniqueId().toString() + ".lastLocation.x", player.getLocation.getX());
plugin.getConfig.set(player.getUniqueId().toString() + ".lastLocation.y", player.getLocation.getY());
plugin.getConfig.set(player.getUniqueId().toString() + ".lastLocation.z", player.getLocation.getZ());
plugin.getConfig.set(player.getUniqueId().toString() + ".lastLocation.world", player.getLocation.getWorld().getName());
plugin.saveConfig();
 
// Query from config
Location location = new Location(
Bukkit.getWorld(player.getUniqueId().toString() + ".lastLocation.world"),
plugin.getConfig().getDouble(player.getUniqueId().toString() + ".lastLocation.y", player.getLocation.getY()),
plugin.getConfig().getDouble(player.getUniqueId().toString() + ".lastLocation.z", player.getLocation.getZ()),
plugin.getConfig().getDouble(player.getUniqueId().toString() + ".lastLocation.z", player.getLocation.getZ())
);
 

Hashmap method;

Code:java

private HashMap<Player, Location> playerLocations = new HashMap<Player, Location>();
 
// Add the player's location
playerLocations.put(player, player.getLocation());
 
// Get the player's location
playerLocations.get(player) // This will return the player's location

 

Write to a file ( or config) and load it up when you need it

 

I've had to do this in a lot of plugins, I usually just make two methods that are static and I just copy/paste them into each new project.

Code:

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

That will allow you to easily parse a precise location into a string and back into a location. Just use getConfig().set("something", locToString(location)); and stringToLoc(getConfig().get("something"));

 

thanks for all the help guys
