Hello, been trying to figure out how to add name tags to players in multiplayer. I setup the 3D Label and set a “player_name” variable. But I can’t figure out how to apply the name from the client connecting to the server.
I have tried a dictionary and making it a global variable. But no matter what I do, it makes the name “31” instead of the name I gave it. I tried RPC and such, but no luck.
The way the name is set is at the main menu, you type the IP and type the name, and then it is supposed to set the name when you join, but instead it gives a 31. I probably don’t fully understand how RPC and such works, trying to get myself accustomed to Godot, and I was half tempted to go back to Unreal due to how frustrating it was and how little information I found on the topic.

Sorry for the mess, been trying to debug this code for several hours now, and been trying mutliple methods and just trying to get it to work, any help would be appreciated.
