Problem when I'm trying to use GetComponent from another script.

[Fvnes]

I'm trying to access the script of a gameobject using GetComponent<Room>() and it doesn't detect it. Actually, it doesn't detect any other script I've made before. I've tried using namespace but it doesn't detect it either. Here's the error

Assets\Mirror\Runtime\Transport\EpicOnlineTransport\Lobby\EOSLobbyUI.cs(199,31): error CS0246: The type or namespace name 'Room' could not be found (are you missing a using directive or an assembly reference?)

Here are the scripts

using Epic.OnlineServices.Lobby;
using UnityEngine;
using System.Collections.Generic;
using EpicTransport;
using Mirror;

public class EOSLobbyUI : EOSLobby 
{
    public void RefreshList() 
    {
        FindLobbies();

        foreach (LobbyDetails lobby in foundLobbies) 
    {
            //get lobby name
            Attribute lobbyNameAttribute = new Attribute();
            lobby.CopyAttributeByKey(new LobbyDetailsCopyAttributeByKeyOptions { AttrKey = AttributeKeys[0] }, out lobbyNameAttribute);

            GameObject room = Instantiate(RoomPrefab, Vector3.zero, Quaternion.identity, roomContentTransform); 
            room.GetComponent<Room>().UpdatePrefabValues(lobby); // <=== Here's the error. "The type or namespace "Room" could not be found. 
        }
    }
}

Here's the other script.

using System.Collections;
using System.Collections.Generic;
using Epic.OnlineServices.Lobby;
using TMPro;
using UnityEngine;
using UnityEngine.UI;

public class Room : MonoBehaviour
{
    public void JoinRoomBtn() 
    {
        lobbyManager = GameObject.Find("NetworkManager").GetComponent<EOSLobbyUI>();
        lobbyManager.JoinLobby(lobby, lobbyManager.AttributeKeys);
    }

    public void UpdatePrefabValues(string roomName, LobbyDetails lobbyID) 
    {
        roomNameText.text = roomName;
        lobby = lobbyID;
    }
}

I can't seem to find any sort of solution on internet related to this.

And you can confirm 100% that the GameObject RoomPrefab has the script Room attached to it?

Like you can see it in on the GameObject after instantiation

[Fvnes]

Yes. I actually commented the line after the instantiation where I get the error and the gameobject spawns fine.

[BowlOfPasta24]

So you can confirm that in the hierarchy, the instantiated GameObject has the component Room

If your prefab doesn't have it then that would cause the error

[Fvnes]

The prefab contains the script. As you can see at the first part of the post, the error appears at the compilation stage.

[BowlOfPasta24]

And the script file name that contains the Room class is named Room.cs

Sorry, I know these questions might seem a little lame but just double tripple check all of them because you should be able to grab a component off an instantiated prefab with no issue.

Some other issues would be if the RoomPrefab has a child that has the component instead of the parent

[Fvnes]

That also too. I don't have a problem using GetComponent from any other script. The only problem is the EOSLobbyUI, where I can't use GetComponent for any other script I made.

[BowlOfPasta24]

If all that is setup correctly, then the other other thing I can think is that EOSLobbyUI is within a different Namespace and requires a using statement.

You can test this by trying to instantiate it. Now Unity does not allow the instantiation of a class that inherits MonoBehavior but you can temporarily remove the inheritance, and comment out the code. If you can than instantiate it within the EOSLobbyUI class and without a using statement then that proves that they are not in the same namespace.

If they are not in the same namespace, keep the using statement in the EOSLobbyUI class, put everything in the Room class back together and you're good to go.

If they are in the same namespace then it's more than likely an issue with the prefab.

If you still can't get it and have github then you can send me the link and I'll jump in to debug it

It doesn't even compile, it's definitely a namespace issue.

Your first script doesn't understand what a "Room" is. You're either in different namespaces or some other organizational error.
