Resolved How to crate/join a host with a variable and access it in player script OnNetworkSpawn method

Let's say I have Two Buttons:

Play as Blue Player

Play as Red Player

The player clicked the "Play as Blue Player" button and I started the host with the Blue parameter;

NetworkManager.Singleton.StartHost();

If the next player clicks the "Play as Red Player", it can connect the created host.

NetworkManager.Singleton.StartClient();

Otherwise, I need to create a new host with a Red parameter.

and I need to know which player is red or blue in the player script OnNetworkSpawn method.

I hope I have achieved to explain my issue

Thanks in advance!

 

I wouldn‘t do it that way. Let one player be the host, the other a client. That‘s one choice. This should be independent of the choice of color. So first player chooses host, second player chooses connect. Host can choose its color, client automatically uses the other color and has no choice in it (host privilege).

 

Hi @CodeSmile thank you so much for your answer but I think I wasn't clear enough.

I want to create one to one match.
Let's say Attack and Defence instead of Red and Blue.

if one player creates an attacking host, only a player who wants to defence should join this host. Otherwise, if the second player selects the attack, it should create a new host instead of joining the previous host.

I hope I have explained my requirement more clearly this time

 

Hi @RikuTheFuffs-U thanks for your answer. I think this is what I need. Is there any sample or nice tutorial for the matchmaker service that you know?

Thanks in advance!

 

Thank you so much!

 

The way I do it is that players select their team on the login screen, which is then sent on the payload. In the approval check the server then checks whether the team choice is (still) valid.

A code snippet for sending the payload:

Code (CSharp):

1. string payload=JsonUtility.ToJson(new ConnectionPayload(playerTeam,playerName,Application.version));
2. byte[] payloadBytes=System.Text.Encoding.UTF8.GetBytes(payload);
3. NetworkManager.Singleton.NetworkConfig.ConnectionData=payloadBytes; //would make sense to add password to this
4. NetworkManager.Singleton.StartClient();

And checking the payload in the approval check (note that ClientDataManager is a custom class that exists only for the server):

Code (CSharp):

1. ConnectionPayload payload=JsonUtility.FromJson<ConnectionPayload>(System.Text.Encoding.ASCII.GetString(connectionData));
2. if (!Application.version.Equals(payload.gameVersion,System.StringComparison.Ordinal)) {
3.     Debug.Log("Version mismatch!");
4.     approveConnection=false;
5. } //if
6. else if (ClientDataManager.instance.NameIsInUse(payload.playerName)) {
7.     Debug.Log("Client name ("+payload.playerName+") is already being used!");
8.     approveConnection=false;
9. } //if
10. else if (ClientDataManager.instance.TeamIsFull(payload.playerTeam)) {
11.     Debug.Log("Client team ("+payload.playerTeam+") is already full!");
12.     approveConnection=false;
13. } //else if
14. else {
15.     ClientDataManager.instance.AddClientData(clientId,payload.playerTeam,payload.playerName);
16. } //else

 

Hey @CosmoM this very looks like what I needed. I will check this tomorrow as far as I can. Thank you so much!
