createJoinRoomWithRoomId create two separate rooms

Postby KVADRO » January 1st, 2019, 3:58 pm

Hi.
I use createJoinRoomWithRoomId as: [_multiplayer createJoinRoomWithroomID:nil roomType:@"test" ... ]; (ios), and as far as i understood first client who call this method will create room, and second should join room witch was created by the first player. But, i see that two separate rooms was created, why?

It should work as long as both rooms are created with the same name. Is it happening every time to test, or only on some rare occasion?

Yes, if i specify specific name in first parameter, two players will join same room. But, i need 'unique' room id, to implement 'return after disconnection' functionality. So, if i specify nil as the first parameter, PIO will generate unique room id for me, and i need this functionality.

I tried on development server, and, it happens each time i call createJoinRoomWithRoomId

No, every time a client, any client, calls CreateJoinRoom with a null roomid value, PlayerIO will create a random roomid, and have the client join that room.

There's no way for a second client to magically know the roomid the first client created, you have to transmit that piece of information to the second client somehow. And if you want the first client to be able to re-connect to the same room, you need to seend that roomid to the first client as well.

Use "$service-room$" as roomId parameter and your players will be matched :P
