Hello! In this course, we will learn how to implement a lobby screen in a network game using Unity. Specifically, we will focus on the “Join Room” feature and explain various methods. During this process, we will use Unity’s UNet<\/strong> to implement network functionality and later expand to other network libraries like Mirror<\/strong>.<\/p>\n The network lobby refers to a space where players wait before joining a specific room in multiplayer games. In the lobby, players gather to adjust game settings and perform tasks such as joining or creating rooms.<\/p>\n To enable network functionality in Unity, you must first set up “Unity Multiplayer<\/strong>“. Install the UNet package via Unity’s Package Manager<\/strong>. You can develop network functionality using this package.<\/p>\n First, create a new Unity project. Next, I will add the necessary UI components to implement the lobby screen.<\/p>\n To create a room, you need to set up the network manager and write the logic for creating a room. Here is an example of room creation code.<\/p>\n After creating a room, we need to display the current list of existing rooms. We will learn about the necessary UI elements and how to update room information.<\/p>\n I will also explain how players can join a room. Here, we will add logic to receive the room name and join that room.<\/p>\n We can also implement the functionality to leave a room. The player will be able to leave the room and return to the lobby screen.<\/p>\n We also need to consider the feature to start the game after all players have joined the room. We can check if all players are ready and start the game.<\/p>\n Once the code is complete, we need to test it locally. Using Unity’s play mode, we should create and join rooms, finding and fixing any errors that occur during the process.<\/p>\n In addition to basic room creation and joining, various features can be added to enhance the lobby interface. For example, displaying room information, player status, and implementing a chat system.<\/p>\n Through this course, we have learned how to implement a network lobby screen in Unity and how to join rooms. Based on this foundational knowledge, you can create more complex network games. In the next course, we will learn how to further develop these features.<\/p>\n <\/body><\/p>\n","protected":false},"excerpt":{"rendered":"1. Understanding the Concept of Network Lobby<\/h2>\n

1.2 Setting Up the Network<\/h3>\n
2. Setting Up the Project<\/h2>\n
using UnityEngine;\nusing UnityEngine.UI;\n\npublic class Lobby : MonoBehaviour\n{\n public Button createRoomButton;\n public Button joinRoomButton;\n\n void Start()\n {\n createRoomButton.onClick.AddListener(CreateRoom);\n joinRoomButton.onClick.AddListener(JoinRoom);\n }\n\n void CreateRoom()\n {\n \/\/ Implement room creation logic\n }\n\n void JoinRoom()\n {\n \/\/ Implement room joining logic\n }\n}<\/code><\/pre>\n3. Creating a Room<\/h2>\n
using UnityEngine.Networking;\n\nvoid CreateRoom()\n{\n if (NetworkServer.active)\n {\n \/\/ Cannot create a room if the server is already running.\n Debug.Log(\"The server is already running.\");\n return;\n }\n\n \/\/ Set room properties\n RoomOptions roomOptions = new RoomOptions();\n roomOptions.MaxPlayers = 4; \/\/ Maximum number of players\n\n \/\/ Create room\n NetworkManager.singleton.CreateRoom(\"New Room\", roomOptions);\n Debug.Log(\"The room has been created.\");\n}<\/code><\/pre>\n4. Getting the Room List<\/h2>\n
using UnityEngine.Networking;\nusing UnityEngine.UI;\n\npublic void UpdateRoomList()\n{\n \/\/ Get room list\n foreach (RoomInfo room in NetworkManager.singleton.RoomList)\n {\n \/\/ Update room information in UI\n Debug.Log(\"Room Name: \" + room.Name);\n }\n}<\/code><\/pre>\n5. Joining a Room<\/h2>\n
void JoinRoom(string roomName)\n{\n if (string.IsNullOrEmpty(roomName))\n {\n Debug.Log(\"Room name is empty.\");\n return;\n }\n\n NetworkManager.singleton.JoinRoom(roomName);\n Debug.Log(\"Joining room: \" + roomName);\n}<\/code><\/pre>\n6. Leaving a Room<\/h2>\n
void LeaveRoom()\n{\n if (!NetworkServer.active)\n {\n \/\/ Leave the room if not a server\n NetworkManager.singleton.LeaveRoom();\n Debug.Log(\"Left the room.\");\n \/\/ Add logic to return to the lobby screen\n }\n}<\/code><\/pre>\n7. Starting the Game<\/h2>\n
