are there any other methods BukkitPlayer and server?

[TheStepashich]

Hello! I'm trying to get the value from BukkitValues the player for whom we are parsing the placeholder...

in theory this is possible if use:

var player = BukkitPlayer;
var plugin = BukkitServer.getPluginManager().getPlugin("Welten");
var ratingKey = NamespacedKey(plugin, "rating");
function rating() {
    var playerData = player.persistentDataContainer;
	var rep = playerData.get(ratingKey, PersistentDataType.INTEGER);
    return rep;
}

rating();

error in line 3. can't determine Namespacedkey.

Any ideas on this? I will be grateful!
