Getting Player UUID from Player Name (1.18.2)

[papakush321]

Hi, I've been struggling for quite a while to get my Packets to work the way I want to. Here is what I want to do. I have ruler item, when the player uses the item it opens up a gui with a text field, I want to be able to put another players name in the text field and it will return how many blocks away you are from the players name whom you typed in the box.  I'm currently struggling to save data in the packet. Also I was told to use getPlayerByUUID and saving data using writeUUID and readUUID, but I dont know what to change in my current code to support this. Thank you in Advance!

 

Here are the relevant classes on Github:

That code is complete rubbish. You are handling a packet serverside by accessing and using client api?

https://forge.gemwire.uk/wiki/Sides

 

Every entity (including players) has a UUID. Entity.getUUID()

This is intended for persistent storage across game restarts.

And allows you to refer to entities/players that are not loaded in the game.

 

If you want a server to tell a client how to get an entity, you will find Entity.getId() more useful.

You use Level.getEntity() client side to retrieve the entity with that id.

Assuming the client knows about that entity, i.e. it is in the client's currently loaded level/chunks.
