Here's a complete Unity solution for a voice chat and text chat game: using UnityEngine; using Unity.Netcode; using Unity.Netcode.Transports.UTP; using VivoxUnity; public class VoiceChatManager : NetworkBehaviour { private VivoxUnity.Client client; private ILoginSession loginSession; private IChannelSession channelSession; [Header("Vivox Settings")] [SerializeField] private string vivoxServer = "https://unity.vivox.com/appconfig/"; [SerializeField] private string vivoxDomain = "mtu1xp.vivox.com"; [SerializeField] private string vivoxIssuer = "your-issuer"; [SerializeField] private string vivoxSecretKey = "your-secret-key"; [Header("Channel Settings")] [SerializeField] private string channelName = "GameChannel"; [SerializeField] private ChannelType channelType = ChannelType.NonPositional; private void Awake() { client = new VivoxUnity.Client(); DontDestroyOnLoad(gameObject); } public override void OnNetworkSpawn() { if (IsServer) { InitializeVivox(); } } private void InitializeVivox() { var accountId = new AccountId(vivoxIssuer, NetworkManager.Singleton.LocalClientId.ToString(), vivoxDomain); loginSession = client.GetLoginSession(accountId); loginSession.BeginLogin(vivoxServer, loginSession.GetLoginToken(vivoxSecretKey, TimeSpan.FromSeconds(90)), ar => { try { loginSession.EndLogin(ar); JoinChannel(); } catch (Exception e) { Debug.LogError($"Login failed: {e.Message}"); } }); } private void JoinChannel() { var channelId = new ChannelId(vivoxIssuer, channelName, vivoxDomain, channelType); channelSession = loginSession.GetChannelSession(channelId); channelSession.BeginConnect(true, true, true, channelSession.GetConnectToken(vivoxSecretKey, TimeSpan.FromSeconds(90)), ar => { try { channelSession.EndConnect(ar); Debug.Log("Connected to voice channel"); } catch (Exception e) { Debug.LogError($"Channel connection failed: {e.Message}"); } }); } private void OnDestroy() { if (channelSession != null && channelSession.ChannelState == ConnectionState.Connected) { channelSession.Disconnect(); } if (loginSession != null && loginSession.State == LoginState.LoggedIn) { loginSession.Logout(); } client?.Uninitialize(); } } using UnityEngine; using Unity.Netcode; using TMPro; using UnityEngine.UI; public class ChatManager : NetworkBehaviour { [Header("UI References")] [SerializeField] private TMP_InputField chatInput; [SerializeField] private Button sendButton; [SerializeField] private ScrollRect chatScroll; [SerializeField] private GameObject chatMessagePrefab; private void Awake() { sendButton.onClick.AddListener(SendChatMessage); chatInput.onSubmit.AddListener(_ => SendChatMessage()); } private void SendChatMessage() { if (string.IsNullOrWhiteSpace(chatInput.text)) return; string message = $"{NetworkManager.Singleton.LocalClientId}: {chatInput.text}"; SendChatMessageServerRpc(message); chatInput.text = ""; } [ServerRpc(RequireOwnership = false)] private void SendChatMessageServerRpc(string message, ServerRpcParams rpcParams = default) { ReceiveChatMessageClientRpc(message); } [ClientRpc] private void ReceiveChatMessageClientRpc(string message) { AddMessageToChat(message); } private void AddMessageToChat(string message) { GameObject newMessage = Instantiate(chatMessagePrefab, chatScroll.content); newMessage.GetComponent().text = message; // Auto-scroll to bottom Canvas.ForceUpdateCanvases(); chatScroll.verticalNormalizedPosition = 0f; } } using UnityEngine; using Unity.Netcode; using Unity.Netcode.Transports.UTP; public class GameNetworkManager : MonoBehaviour { [SerializeField] private GameObject networkManagerPrefab; private void Awake() { if (NetworkManager.Singleton == null) { Instantiate(networkManagerPrefab); } } public void StartHost() { NetworkManager.Singleton.StartHost(); } public void StartClient() { NetworkManager.Singleton.StartClient(); } } using UnityEngine; using UnityEngine.UI; using TMPro; public class LobbyUI : MonoBehaviour { [Header("UI References")] [SerializeField] private Button hostButton; [SerializeField] private Button joinButton; [SerializeField] private TMP_InputField ipInput; private void Awake() { hostButton.onClick.AddListener(StartHost); joinButton.onClick.AddListener(StartClient); } private void StartHost() { GameNetworkManager.Instance.StartHost(); gameObject.SetActive(false); } private void StartClient() { string ip = string.IsNullOrEmpty(ipInput.text) ? "127.0.0.1" : ipInput.text; NetworkManager.Singleton.GetComponent().SetConnectionData(ip, 7777); GameNetworkManager.Instance.StartClient(); gameObject.SetActive(false); } } To set this up: 1. Install required packages: - Netcode for GameObjects - Unity Transport - Vivox Unity SDK (from Vivox website) 2. Create the UI: - Chat panel with input field, send button, and scroll view - Lobby UI with host/join buttons and IP input 3. Set up Vivox: - Create a Vivox developer account - Configure issuer and secret key in VoiceChatManager 4. Network setup: - Create a NetworkManager prefab with UnityTransport - Assign the prefab to GameNetworkManager 5. For voice chat: - Players will automatically join the voice channel when they connect - Make sure to handle microphone permissions on target platforms 6. For text chat: - Messages are sent via Netcode RPCs - Each message shows the sender's client ID This provides a complete foundation for a multiplayer game with both voice and text chat functionality.
