I use script messages for broadcasting events in my game and they are needed to be in order.

(ex : A sent EVENT 0, and broadcasting EVENT 0 to all players

        B sent EVENT 1, and broadcasting EVENT 1 to all players , etc.)

But I encountered messages lost and out of order.

Ex : Some messages (msg0, 1, 2) sent to 3 players, but one of players lost 0 and got 2 first ,then 1, the other two were fine.

Is that normal? Do I need to build a re-sync mechanism by myself?

Thanks

Hi

Sorry for confusing.

The timeline of the issue is following:

*Three Players A, B, C, iOS SDK clients.*

1. A sent EVENT 0, then Cloud code broadcasted Message 0 to A,B,C. 

    B,C got it immediately.

2. B sent EVENT 1, then Cloud code broadcasted Message 1 to A,B,C.

    B,C got it immediately.

3. C sent EVENT 2, then Cloud code broadcasted Message 2 to A,B,C.

    B,C got it immediately. 

    A got Message2 first, then Message1. Message 0 lost.

Thanks,

Jo

Hi

No, it rarely happens but did happen. So I don't think that A is not in the list.

B and C got their own messages.

Hi

The gameId = 120246

I use iOS SDK message listener to listen the messages.

Sorry I have no time to make a simple duplicatable case.

I temporally to add a mechanism to detect if message lost and resync.

But still hope that the platform can make sure they are in order.

Thanks.

Hi

I found that if the SDK disconnects and reconnects several times, ALL messages may not be delivered at all.

I guess maybe your server does not send messages to the right socket since multiple sockets were built.

Please check it.

Thanks
