Im doing something wrong here and idk what. Im trying to send data from GameManager to uiManager so uimanager can display some ui. failing spectacularily.

also expect some weird half-written code in the parts that reference ui here, sorry.

using UnityEngine;
using System.Collections.Generic;
using UnityEngine.UI;

public class GameManager : MonoBehaviour
{

    private const string PLAYER_ID_PREFIX = "Player ";


    public static Dictionary<string, Player> players = new Dictionary<string, Player>(); // freaking tutorial doesnt say to use void start 


    public static GameManager GMinstance;

    private GameObject uimgr = GameObject.FindWithTag("uiManager");
    
    void Awake()
    {
        GMinstance = this;
    }

    [SerializeField]
    private Text playerList;

    public static void RegisterPlayer(string _netID, Player _player)
    {

        string _playerID = PLAYER_ID_PREFIX + _netID;
        players.Add(_playerID, _player); // Player 1, 0af68923r
        _player.transform.name = _playerID;
        uimgr.DisplayUI();


    }

    public static void UnRegisterPlayer(string _playerID)
    {

        players.Remove(_playerID);

    }

    public static Player GetPlayer(string _playerID)
    {

        return players[_playerID];

    }


}

.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class uiManager : MonoBehaviour
{

    public static void DisplayUI(string _playerID, )
    {

        foreach (string _playerID in players.Keys)
        {

            GMinstance.playerList.text = GMinstance.playerList.text + _playerID + " - " + players[_playerID].transform.name + "/n";

        }

    }

}

i can not understand your code, and seems unfinished, whats your problem? for some reason your display ui method has a ‘,’ are you expecting a second var? you cnt access a static var like that you need to rfernce the class, rather than

GMinstance.playerList....

to

GameManager.GMinstance.playerList....

third you cant access a private var like playerList, you need to make it public or create getters/setters
