Player Data

Registering a custom player data tag

First, you need to register a tag in the player data that should be watched.

PlayerDataRegistry.registerKey(key, persistent, sync);

key is the Tag Key in the NBT Data of the Player. persistent means the key will be restored when the player respawns and keepInventory is false. When sync is true, the value will be synced to all clients.

Or, if you want to specificy, whether it should just sync to it's owner instead of all players, you can use the following code:

PlayerDataRegistry.registerKey(key, persistent, syncToSelf, syncsToAll);

Check if Key is registered

You can use PlayerDataRegistry.isKeyRegistered(key){:.language-java .highlight} to check if your key is registered.

PlayerDataRegistry.keySet().contains(key);

Check if persistent / syncs

You can use PlayerDataRegistry.isKeyPersistent(key){:.language-java .highlight} to check if a key is persistent and PlayerDataRegistry.shouldSyncKey(key){:.language-java .highlight} to check if a key syncs to all clients. To check if your key syncs to the owner of the nbt tag, use PlayerDataRegistry.shouldSyncTagToSelf(key){:.language-java .highlight} and to check, whether it should sync to other players, use PlayerDataRegistry.shouldSyncTagToAll(key){:.language-java .highlight}.
