How to use multiple player prefabs for Unity's new UNET? - unity3d

Has anyone got multiple player prefabs working (eg different character classes with different prefabs) on the new Unity UNET Networking?

Finally got it working!
Massive thank you to #ClausKleber for their answer at

Edited working version below, Works with the Network Manager HUD to create and join.
using UnityEngine;
using System.Collections;
using UnityEngine.Networking;
using UnityEngine.UI;
public class NetManagerCustom : NetworkManager
{
// in the Network Manager component, you must put your player prefabs
// in the Spawn Info -> Registered Spawnable Prefabs section
public short playerPrefabIndex;
public override void OnStartServer()
{
NetworkServer.RegisterHandler(MsgTypes.PlayerPrefab, OnResponsePrefab);
base.OnStartServer();
}
public override void OnClientConnect(NetworkConnection conn)
{
client.RegisterHandler(MsgTypes.PlayerPrefab, OnRequestPrefab);
base.OnClientConnect(conn);
}
private void OnRequestPrefab(NetworkMessage netMsg)
{
MsgTypes.PlayerPrefabMsg msg = new MsgTypes.PlayerPrefabMsg();
msg.controllerID = netMsg.ReadMessage<MsgTypes.PlayerPrefabMsg>().controllerID;
msg.prefabIndex = playerPrefabIndex;
client.Send(MsgTypes.PlayerPrefab, msg);
}
private void OnResponsePrefab(NetworkMessage netMsg)
{
MsgTypes.PlayerPrefabMsg msg = netMsg.ReadMessage<MsgTypes.PlayerPrefabMsg>();
playerPrefab = spawnPrefabs[msg.prefabIndex];
base.OnServerAddPlayer(netMsg.conn, msg.controllerID);
Debug.Log(playerPrefab.name + " spawned!");
}
public override void OnServerAddPlayer(NetworkConnection conn, short playerControllerId)
{
MsgTypes.PlayerPrefabMsg msg = new MsgTypes.PlayerPrefabMsg();
msg.controllerID = playerControllerId;
NetworkServer.SendToClient(conn.connectionId, MsgTypes.PlayerPrefab, msg);
}
// I have put a toggle UI on gameObjects called PC1 and PC2 to select two different character types.
// on toggle, this function is called, which updates the playerPrefabIndex
// The index will be the number from the registered spawnable prefabs that
// you want for your player
public void UpdatePC ()
{
if (GameObject.Find("PC1").GetComponent<Toggle>().isOn)
{
playerPrefabIndex = 3;
}
else if (GameObject.Find("PC2").GetComponent<Toggle>().isOn)
{
playerPrefabIndex= 4;
}
}
}

Create a new class that derives from the built-in NetworkManager script. In there, just add a few supporting fields and an override for OnServerAddPlayer().
[SerializeField] Vector3 playerSpawnPos;
[SerializeField] GameObject character1;
[SerializeField] GameObject character2;
// etc.
GameObject chosenCharacter; // character1, character2, etc.
// Instantiate whichever character the player chose and was assigned to chosenCharacter
public override void OnServerAddPlayer(NetworkConnection conn, short playerControllerId) {
var player = (GameObject)GameObject.Instantiate(chosenCharacter, playerSpawnPos, Quaternion.identity);
NetworkServer.AddPlayer(conn, player, playerControllerId);
}

How to load next scene when pressed a button while playing in unity

This what I tried,
I was watching Brackeys
public void PlayGame()
{
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
};
Your script probably doesn't work if you have 1 scene, or the current scene is at the end of the list in Build Settings.
Also you can use it this way:
//Add scenes in inspector
[SerializeField] private List<Scene> _sceneList;
public void LoadNextScene()
{
int currentScene = SceneManager.GetActiveScene().buildIndex;
if (currentScene < _sceneList.Count)
SceneManager.LoadScene(_sceneList[currentScene + 1].buildIndex);
else
print("Its last scene");
}
You can use SceneManager.LoadScene() method to load the Scene by its name or index in Build Settings.
The SceneManager.GetActiveScene().buildIndex gives you the index number of the current scene and you can add an incremental value to navigate to the next scene.
To do that,
Create a new script named SceneController and methods as follows,
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class SceneController : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
}
public void LoadMenuScene() {
SceneManager.LoadScene("MenuScene");
}
public void NextScene() {
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
}
public void ReloadScene() {
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
}
}
Add the script to the Canvas object
Add the method to the button OnClick event in the inspector
NB: You can also use name or index values to load the scene (like LoadMenuScene)

How to network a VR button with PUN in Unity?

I've been working on a solution for weeks now and I think it's time to reach out. I'm trying to make a button that plays a sound when pressed by a controller, everyone will hear that sound. Using VRTK and PlayoVR, I'm able to make a non-networked version where the player can put their hand through a cube, click the trigger from the controller, and it makes a sound.
This is the code for that cube:
namespace VRTK.Examples {
using UnityEngine;
public class Whirlygig : VRTK_InteractableObject
{
public GameObject AudioSource;
public AudioSource LeftSpeaker;
public override void StartUsing(VRTK_InteractUse currentUsingObject =
null)
{
AudioSource.GetComponent<AudioSource>().Play();
}
}
}
Where I get lost is how to network it with Photon Unity Networking. This is what I have:
namespace PlayoVR
{
using UnityEngine;
using VRTK;
using UnityEngine.Video;
using NetBase;
public class PlaySync : Photon.MonoBehaviour
{
public AudioSource LeftSpeaker;
public GameObject Whirlgig;
private bool StartUsing;
// Use this for initialization
void Awake()
{
GetComponent<VRTK_InteractableObject>().InteractableObjectUsed +=
new InteractableObjectEventHandler(DoPlay);
}
void DoPlay(object sender, InteractableObjectEventArgs e)
{
StartUsing = true;
}
// Update is called once per frame
void Update()
{
// Handle firing
if (StartUsing)
{
CmdPlay();
StartUsing = false;
}
}
void CmdPlay()
{
photonView.RPC("NetPlay", PhotonTargets.All);
}
[PunRPC]
void NetPlay()
{
LeftSpeaker.Play();
}
}
}
As you can probably see, I'm a beginner. With this code, when I put my hand in the cube and press the trigger, nothing happens. If anyone can provide any help or even an alternative, I'd be very grateful.
Kind regards,

Multiplayer [SyncEvent] problem with non-player objects

I'm developing a multiplayer game based on turns.
So I have an script named gameController which is the one who has the global timer to alter the turns and also choose which players are attacking and which players are defending in the current turn.
This script is a singleton attached to a gameObject with a network identity on it (This network identity has no checkboxes marked to be controller by the server). I tried to have this game object spawned to all the clients when the server connects and also to have the game object already in the scene (booth cases aren't working).
Well, the main problem is that in the gameController script I have a checker in the update function to check if any new player is connected. In case is connected, it should call a syncEvent named EventOnNewPlayerAddedDelegate (I tried to call it directly, also using [command] and using [ ClientRpc]) to let the players know that they have to call their function named "OnRegisterPlayer", which is a function in their own player script that calls a function on gameController script, passing the player object (I tried via command and rpc also), something like this: GameController.instance.RegisterPlayer(this);
So anyone knows how can I trigger this SyncEvent to register the player to a non-player object controlled by the server?
Thank you very much.
I attach here a brief of booth scripts to make it easier to understand:
GameController:
public class GameController : NetworkBehaviour
{
public delegate void OnNewPlayerAddedDelegate();
[SyncEvent]
public event OnNewPlayerAddedDelegate EventOnNewPlayerAddedDelegate;
List<GamePlayerManager> players = new List<GamePlayerManager>();
public static GameController instance { get; private set; }
float timePerTorn = 30f;
bool isCountdown = false;
[System.NonSerialized]
public float countdownTime;
int roundNumber = 0;
int NumberOfPlayers;
int NumberOfPlayersChanged;
void Awake()
{
Debug.Log("Awaking ");
if (instance != null)
{
Debug.Log("Destoring ");
DestroyImmediate(this);
return;
}
instance = this;
}
// Use this for initialization
void Start()
{
if (!isServer)
{
return;
}
players = new List<GamePlayerManager>();
StartCountdown(5f);//20
}
void Update()
{
if (isServer)
{
if (isCountdown)
{
countdownTime -= Time.deltaTime;
if (countdownTime <= 0)
{
AlterGlobalTurns();
}
}
}
NumberOfPlayers = NetworkManager.singleton.numPlayers;
if (NumberOfPlayersChanged != NumberOfPlayers)
{
Debug.Log("num of players changed ---> " + NumberOfPlayers);
NumberOfPlayersChanged = NumberOfPlayers;
EventOnNewPlayerAddedDelegate();
//RpcNewPlayerAdded();
//CmdNewPlayerAdded();
}
}
[ClientRpc]
void RpcNewPlayerAdded()
{
Debug.Log("---------------- RpcNewPlayerAdded ------------");
EventOnNewPlayerAddedDelegate();
}
[Command]
void CmdNewPlayerAdded()
{
Debug.Log("---------------- CmdNewPlayerAdded ------------");
EventOnNewPlayerAddedDelegate();
}
public void RegisterPlayer(GamePlayerManager player)
{
Debug.Log("player ---> " + player.name);
if (players.Contains(player))
{
return;
}
Debug.Log("players ---> " + players);
players.Add(player);
}
}
PlayerScript:
public class GamePlayerManager : NetworkBehaviour
{
[System.NonSerialized]
public bool isPlayingOnTorn = true;
void Awake()
{
GameController.instance.EventOnNewPlayerAddedDelegate += OnRegisterPlayer;
}
private void Start()
{
if (!isLocalPlayer)
{
return;
}
}
public override void OnStartServer()
{
GameObject gc = (GameObject)Instantiate(NetworkManager.singleton.spawnPrefabs[2], transform.position, transform.rotation);
NetworkServer.Spawn(gc);
}
void OnRegisterPlayer(){
if (isLocalPlayer)
{
//GameController.instance.RegisterPlayer(this);
//RpcRegisterPlayer();
CmdRegisterPlayer();
}
}
[Command]
void CmdRegisterPlayer(){
Debug.Log("-------------Command Register player -------------");
GameController.instance.RegisterPlayer(this);
}
[ClientRpc]
void RpcRegisterPlayer()
{
Debug.Log("------------- RPC REgister Player -------------");
GameController.instance.RegisterPlayer(this);
}
}
I think I already saw the problem here.
The problem is that GameController is spawned by the playerScript(just if the player is also the host) in the function OnStartServer(). So the first problem is that the GameController doesn't detect the host player because it is not a new connections. And the second problem is when a second client is connected, the GameController detect the client connection and send the event signal faster than the client wakeup, so when the client is already working the signal is gone.
I solved the problem deleting this signal and checking directly in the playerScript if the GameController exists then check if the player is already registered.
My question now is that if there is anyway to instance and awake the server objects before the player(Host), which I understand that the answer is "no" because as the player is the host it needs to be running to have the server.
And the second question is if there is anyway or any signal to know that a new player is connected, and wait until it is awaked.
Thank you very much.

In VR development ,how can I make a handle shotting?

I want to make an example of shot,
then I wrote this in the handle button event,
using UnityEngine;
using System.Collections;
public class fire : MonoBehaviour {
public GameObject bullet;
SteamVR_TrackedObject trackedObj;
void start() {
trackedObj = GetComponent<SteamVR_TrakedObject>();
}
void Update() {
var device = SteamVR_Controller.Input((int)trackedObj.index);
if (device.GetTouchDown(SteamVR_Controller.ButtonMask.Trigger)) {
GameObejct obj = Instantiate(bullet,transform.position);
Vector3d fwd = transform.TransformDirection(Vector3.forward);
obj.GetComponent.<Rigidbody>().AddForce(fwd*2800);
}
}
}
but when debugging and I press handle button ,it didn't produce a bullet,and had erred at the line
var device = SteamVR_Controller.Input((int)trackedObj.index);,
the error is:
Object reference not set to an instance of an object.
First You should need to confirm that your fire script is attached to your controller object and your controller object also attached SteamVR_TrackedObject script (which provide by steam plugin).
Then, lastly ensure this line is executing
void start() {
trackedObj = GetComponent<SteamVR_TrakedObject>();
}

How to display a name and score list for players using happyfuntimes and unity3d

This is related to happyfuntimes plugin if you have used it .
I am trying to make a game on it and stuck at a point of displaying score along with name to display on large screen while user is playing on his mobile.(i have already tried to display name and score on mobile screens have seen in sample do not need that ). Please suggest how can this be done if you have used happyfuntimes plugin.
I could see the HFTgamepad input having public GameObject player name which I am trying to access ,do I have to make array ?
public string playerName;
I am trying to put these name on array.
Displaying anything in unity is really normal unity issue and not special to happyfuntimes. Games display highscore lists, item lists, inventory lists, etc... A list of players is no different
Use the GUI system display text.
According to the docs if you want to generate UI dynamically you should make a prefab
So basically you'd make a UI hierarchy in the scene. When a player is added to the game Instantiate your name-score prefab, search for the UI hierarchy gameObject (do that at init time), then set the parent of the preafab you just instantiated so it's in the UI hierarchy.
Look up the UI.Text components that represent name and score and set their text properties.
There's various auto layout components to help layout your scores
When a player disconnects Destroy the prefab you instantiated above.
OR ...
Conversely you can use the old immediate mode GUI. You'd make a GameObject, give it a component that has a OnGUI function. Somewhere keep a list of players. Add players to the list as they connect and remove them from the list as they disconnect. In your OnGUI function loop over the list of players and call the GUI.Label function or similar to draw each name and score
Here's a hacked up example.
Assuming you have a PlayerScript script component that's on each player that has a public accessor PlayerName for getting the player's name then you can make a GameObject and put a script like this on it.
using UnityEngine;
using System.Collections.Generic;
public class ExamplePlayerListGUI : MonoBehaviour
{
static ExamplePlayerListGUI s_instance;
List<PlayerScript> m_players = new List<PlayerScript>();
static public ExamplePlayerListGUI GetInstance()
{
return s_instance;
}
void Awake()
{
if (s_instance != null)
{
Debug.LogError("there should only be one ExamplePlayerListGUI");
}
s_instance = this;
}
public void AddPlayer(PlayerScript bs)
{
m_players.Add(bs);
}
public void RemovePlayer(PlayerScript bs)
{
m_players.Remove(bs);
}
public void OnGUI()
{
Rect r = new Rect(0, 0, 100, m_players.Count * 20);
GUI.Box(r, "");
r.height = 20;
foreach(var player in m_players)
{
GUI.Label(r, player.PlayerName);
r.y += 20;
}
}
}
PlayerScript can then call ExamplePlayerListGUI.GetInstance().AddPlayer in its Start function and ExamplePlayerListGUI.GetInstance().RemovePlayer in it's OnDestroy function
public PlayerScript : MonoBehaviour
{
private string m_playerName;
...
public string PlayerName
{
get
{
return m_playerName;
}
}
void Start()
{
...
ExamplePlayerListGUI playerListGUI = ExamplePlayerListGUI.GetInstance();
// Check if it exists so we can use it with or without the list
if (playerListGUI != null)
{
playerListGUI.AddPlayer(this);
}
}
void OnDestroy()
{
...
ExamplePlayerListGUI playerListGUI = ExamplePlayerListGUI.GetInstance();
if (playerListGUI != null)
{
playerListGUI.RemovePlayer(this);
}
}
}
