Hi there,
I am trying to use the Party feature of Nakama with the Unity SDK.
I have code to send a party invite, which looks like this:
private async void InviteFriendToParty()
{
IParty party = _connection.CurrentParty;
try
{
if (party == null) {
party = await _connection.Socket.CreatePartyAsync(false, 4);
_connection.SetParty(party);
}
Debug.Log($"Party: {_connection.CurrentParty.Id}");
}
catch (Exception e)
{
Debug.LogError("Inviting friend failed (" + e.Message + ")");
}
try
{
var payload = new Dictionary<string, string>
{
{ "username", _connection.Account.User.Username },
{ "friendId", _friend.User.Id },
{ "partyId", party?.Id }
};
var response =
await _connection.Client
.RpcAsync(_connection.Session, "inviteFriendToParty", payload.ToJson());
Debug.Log("Party invite send successfully");
}
catch (ApiResponseException ex)
{
Debug.LogFormat("Error: {0}", ex.Message);
}
}
On the server, I have an RPC function that sends the Party Invite to the Friend as a notification, which looks like this:
const inviteFriendToParty: nkruntime.RpcFunction =
function (ctx: nkruntime.Context, logger: nkruntime.Logger, nk: nkruntime.Nakama, payload: string) {
const content = JSON.parse(payload);
const inviterUserName = content.username;
const inviteeUserId = content.friendId;
const notification: nkruntime.NotificationRequest = {
code: 4,
content: content,
persistent: false,
subject: `Join ${inviterUserName}'s party!`,
userId: inviteeUserId,
}
nk.notificationsSend([notification]);
}
This triggers and fires off the Notification to the Friend perfectly, and the Friend receives the Party Invite.
In my notification to the Friend, they get a button that says “Join Party”, which executes this code:
private async void JoinPartyInvite(string partyId)
{
try
{
await _connection.Socket.JoinPartyAsync(partyId);
}
catch (Exception e)
{
Debug.LogError("Joining party failed (" + e.Message + ")");
}
}
and I have a listener on my client’s Socket that listens for the ReceivedParty event from Nakama, which looks like this:
_socket.ReceivedParty += party =>
{
Debug.Log("Joined party: " + party);
};
However, nothing happens.
No error message, no Debug.Log message from above.
Nothing.
I did notice in my server logs, that this pops up when I attempt to accept the Party invite:
{"level":"debug","ts":"2022-04-16T04:29:59.064Z","caller":"server/pipeline.go:65","msg":"Received *rtapi.Envelope_PartyJoin message","uid":"c6f4e975-b0c0-430f-9b78-1f28517f42a6","sid":"c3a7c69b-bd3d-11ec-8748-006100a0eb06","cid":"0","message":{"PartyJoin":{"party_id":"4d1ed84b-9064-44cd-ac1b-8c5c5de0f1b0.nakama"}}}
{"level":"debug","ts":"2022-04-16T04:29:59.064Z","caller":"server/session_ws.go:395","msg":"Sending <nil> message","uid":"c6f4e975-b0c0-430f-9b78-1f28517f42a6","sid":"c3a7c69b-bd3d-11ec-8748-006100a0eb06","envelope":"cid:\"0\""}
It is strange to me that it says “Sending <nil> message”.
What am I doing wrong?
Any and all help is appreciated.
Thank you
