ok so you send packets to the server but how do i save the data? is there a specific piece of code?

PS I made the packet handler

javadoc says the method "getEntityData()" return a nbt that will be written to disk

 

im guessing just call the same thign... server side...

 

im doing something similar but im using mysql instead of the nbt. so I'm not sure but it looks pretty straightfoward

but how to call it server side

playerMP.getEntityData().setInteger("level", theLevel);

you mean i create

EntityPlayerMP playerMP;

?

nono, if you do that youll literally create a new player

 

okay you know in the function "handle(INetworkManager manager, Packet250CustomPayload packet, Player player)"

cast the Player reference to a EntityPlayerMP and its THIS reference to write stuff to the nbt

could you please explain how to cast it
