Third Party Spawning in different spawn locations in photon

Hello everyone, I've been struggling with this for the last weekend, I've been doing a lot of research across the network and I can't find a true solution to my problem. I'm making a multiplayer game for android using photon - I have to say, it's my first attempt of making a networked game. I have the connection working fine and the players spawning fine as well, but they all spawn in the same spawn point. Now, to fix that problem, I made ad array of Transforms that contains 4 spawnpoints. When I instantiate the player I use the Random.Range method to randomly pick one of the 4 spawnpoints. But this is not enough because there will always be 1 out of 4 chances that the players spawn in the same location. I'd like to implement a function that allows me to spawn players in round (i.e, first player to spawn will be in location 1, second player in location 2 and so on). In unet this exists, it's called the RoundRobin method, but apparently this doesn't exists in photon...any suggestion? You can find the code I'm using below, what I was trying to do was using an int variable "positionNumber" that when is 0 the player is spawned in location 1 and then the variable is incremented to 1 and "stored" in the network via rpc so that the next player that logs in will see that positionNumber is equal to 1 so it will go to location 2...But I'm not sure I'm using the rpc correctly.
Thank you very much even just for reading all of this.

Weeell, I don't know if no one replied because no one knew the solution or because it was a silly question...But anyway I I found a solution to my problem by myself and I feel like sharing

It might not be the best solution but it works for me:
I created a function that checks the number of players in the room as soon as the player connects. Depending on the number of the players already in the room the new player will be spawned in the latest spawn point available, which means that if the number of players in the room is 3, then the new player will go to spawn point 4. The fifth player will restart the cycle spawning in spawn point 1, player 6 in spawn point 2 and so on.

here's the code

Thank you for sharing the solution ! I was searching for the same thing .

 

THX! it work for me!

 

If this solution works for you, it's totally fine

I missed this post earlier, sorry. Now, I could also point everyone to the "ColorPerPlayer" script, which is now part of the PUN demos. We pick colors for each player, out of the available, editable range. The same principle could be applied to spawn points, of course.

 

I also find this post to be almost the perfect solution. I've been searching for weeks, maybe a month or two. Almost perfect because I get the following error ....

Assets/DLink.cs(108,33): error CS0103: The name `ConnectButton' does not exist in the current context

I've built a button in the UI system and named it ConnectButton, and the error persists. I tried changing the private
variable to a public so I could drag and drop the UI component, but noooooooooo. The error prevented the script compiling. I have a game object with my button function that I named ConnectButton, but when I drag that onto the
button script wizard component function thing it doesn't give access to that scripts function. More than a year later,
my question is how to I create a ConnectButton and get it to connect to this essential Class? The script is 99.9%
just as you created it, except I had to change the name because I believe it conflicted with the built in UNET Game Manager script.

Thanks in advance.

 

I know you posted this 1 year ago and you are past this now but for others that are looking for a solution and get to this page; I'm not sure why you have all those "if else" statements when you can just do this -

[PunRPC]
private void SpawnPlayer(){
spawnPoints = GameObject.FindGameObjectsWithTag("pSpawnP");
int numberofP = PhotonNetwork.playerList.Length;
PhotonNetwork.Instantiate(playerPrefabE.name, spawnPoints[numberofP - 1].transform.position, spawnPoints[numberofP - 1].transform.rotation, 0);
}

Also you should use PhotonNetwork.playerList.Length instead of countOfPlayers, which i believe is all players connected to the game.

But dont use this method! because if you have two players spawn in and the first person leaves there will be one person left in the second spawn but if another player comes in the count will be two and the second person will spawn in the second spawn point which is occupied so they will spawn on top of each other.

 

hI THANKS FOR THE SOLUTION, I was searching for this.

 

Hi @tobiass,

In which demo exactly?

Grtz
Nikola

 

Found it,

In the DemoBoxes!

 

Ciao Giuseppe non so se risponderai visto quanto tempo è passato ma ho copiato il tuo script ed oggi crea un errore in visual studio con la voce ConnectButton. Io uso Unity 2018.2

 

Has anyone found a solution to the error with Unity 2018?

 

Guiseppe shared his solution, right?
If you don't have the exact same issue or if the solution doesn't apply to your game, please open a new post with details.

 

Code (CSharp):

1. SpawnPoints [0] = GameObject.Find ("LevelSpawnRed");
2.         SpawnPoints [1] = GameObject.Find ("LevelSpawnGreen");
3.         SpawnPoints [2] = GameObject.Find ("LevelSpawnBlue");
4.         SpawnPoints [3] = GameObject.Find ("LevelSpawnYellow");
5.  
6.         if (PhotonNetwork.player.ID == 1)
7.             obj = PhotonNetwork.Instantiate (Path.Combine ("Prefabs", "Tank"), SpawnPoints [0].transform.position, Quaternion.identity, 0);
8.         else if (PhotonNetwork.player.ID == 2)
9.             obj = PhotonNetwork.Instantiate (Path.Combine ("Prefabs", "Tank"), SpawnPoints [1].transform.position, Quaternion.identity, 0);
10.         else if (PhotonNetwork.player.ID == 3)
11.             obj = PhotonNetwork.Instantiate (Path.Combine ("Prefabs", "Tank"), SpawnPoints [2].transform.position, Quaternion.identity, 0);
12.         else if (PhotonNetwork.player.ID == 4)
13.             obj = PhotonNetwork.Instantiate (Path.Combine ("Prefabs", "Tank"), SpawnPoints [3].transform.position, Quaternion.identity, 0);

 

Hi QashiCheema the script you posted would be an addition to the script that is at the top of the post? if yes, where should it be added? Thank's

 

For those who get the error code for [......: error CS0103: The name `ConnectButton' does not exist in the current context] here is a correction for this code to suit your pure script

Code (CSharp):

1.  void Update()
2.     {
3.        // StartGame = ConnectButton.Connect;
4.  
5.  
6.

9.         {
10.  
11.             ConnectingText.enabled = false;
12.             //Deactivate the Connection button
13.             ConnectButtonGO.SetActive(false);
14.             //Run CheckPlayer function to determine how many players there are in the room already
15.             CheckPlayers();
16.             standbyCamera.enabled = false;
17.             //Debug.Log("Players in the room after start pressed " + PhotonNetwork.countOfPlayers.ToString());
18.             //Determine which spawn point to use based on the number of player
19.             if (numberPlayers == 1)
20.             {
21.                 PhotonNetwork.Instantiate("Audi", spawnPoint[0].position, spawnPoint[0].rotation, 0);
22.                 numberPlayers = 2;
23.                 StartGame = false ;
24.                 //ConnectButton.Connect = false;

47.         }
48.     }

 

Hi Ivanooo thanks for the reply. I want to ask you I only need the part of spawpoint because I would use the script with Realistic Car Controller. In your opinion how can I modify the script? Unfortunately I don't know much about scripts. Thank you

 

'Don't know much about scripts', making a multiplayer game. Not a great combination in my opinion.

I'd suggest you spend some time getting more familiar with Unity, C# and coding in general, and then when you've finished a couple or more single player games revisit your idea for a multiplayer game.

 

Hi Munchy2007 you are right and in fact a couple of single player games I managed to develop them thanks to the help of some scripts that I found on the net and that I was able to adapt. Mine for Unity is a beautiful passion but with scripts I am denied and so I was looking for someone who has passion and desire to help me with simple scripts, I don't need to do things that are too complex. Thank's

 

For me non of the above solutions worked. That ColorPerPlayer script has alot of errors.

same with using PhotonNetwork.player.ID

Finally, created playerpref scrips in waitingroom by which assigned each player with numbers. So each time +1 player enters room playerprefs increases by one. Those number were perfect for creating spawn points in playing level

 

Code (CSharp):

1.         PhotonNetwork.Instantiate("NetworkPlayerController", _spawnPoint[PhotonNetwork.LocalPlayer.ActorNumber - 1].transform.position, _spawnPoint[PhotonNetwork.LocalPlayer.ActorNumber - 1].transform.rotation);
2.  

 

Thank you. I did not try but I think it will work

 

Thank you bazilbaachu(https://answers.unity.com/users/1127669/bazilbaachu.html).
I am posting my entire workflow of instantiating players at different positions:
Initially checking whether we are master client or not:
Then obtain list of players and send rpc to each of them individually on positions to spawn them.You can store an array of positions and send index in rpc.
Here is the code:
photonView = PhotonView.Get(this);
if(PhotonNetwork.IsMasterClient)
{
foreach(Player pl in PhotonNetwork.PlayerList)
{
//Debug.Log(pl);
photonView.RPC("InstantiationPlayer",pl,index);

index++;
}
}
[PunRPC]
void InstantiationPlayer(int index)
{

PhotonNetwork.Instantiate(Playerprefabs[value].name,SpawnPoints[index].transform.position, Quaternion.identity, 0);
}
Thank you.
