Hi, I can not find much regarding party in server runtime framework documentation. I want to know if I can find members of the party if given a party id.
Usually parties are operated on through the API expose by the socket. Could you elaborate a bit more on what you are trying to achieve?
It depends on what you actually have to do, if you’ll like to have a list with all the parties and their members or get a party object by id, you’ll probably have to create a custom RPC call to get all the data you need.
But if you want a list for the members of the group you are currently in, you just have to assign a function to the socket.ReceivedParty and you’ll have there a list with their presence.
I wanted this on the server side, not client side. I think streams can be used for this but when I pass in the the party Id that I get from the client, StreamSend, the client isn’t receiving any message:
Used the event
Do I need to explictly add users to stream ? I assumed joinging and being in a single party makes them a part of the stream
No, I tagged server-framework for a reason.
I tried using
StreamUserJoin with subject PartyId, but that fails with “stream subject must be a valid identifier” error.
I checked the party Id it contains a alphanumeric uuid with “.nakama1” appended to it
This was not working because we need a socket connection to have a correct session id for stream calls.
So, I changed the whole process and instead listen to After hook for PartyJoin to join stream.
Note to everyone else and @novabyte (please see if anything here can be streamlined):
- Streams are not joined automatically even though intuitively it makes sense to have it automatic.
- You can listen to PartyJoin message to capture user and explictly add them to the party stream.
- PartyJoin message is not received when it is created for the first time by the party leader, which means party leader needs to join party stream explicitly via an RPC.
@demon What version of Nakama are you on because I think what you’ve suggested is outdated. Also do you use our Unreal OnlinePartySubsystem integration or is this the Realtime Parties feature in Nakama?
I am using 3.15 and Realtime Parties.
