Help with multiplayer name sync script

Unity Engine

1

Hello everybody! I’m having problems synchronizing the player’s playername with other clients, I start the server and enter through the client, the name appears above my player, but when I use another client the names are buggy, both player1 and player2 the ui of nametext does not follow each one individually.

I would like some help getting the nametext UI to follow each unique player and see other players and their name following the same. 2d top down mmorpg style

Any help and thank you very much!

> Edit: Canvasprefab is in screen space - overlay because in worldscreen it bugs the position of the canvas
