I wonder if we shouldn't add a test for this case? And also question if this should be also ported to develop branch (NGOv1.X) |
|
I'll add a test case and backport the changes to 1.X. |

This avoids the error message reported in MTTB-1143.
The
UnityTransport.Sendmethod would happily accept invalid or stale connections, which would lead to the allocation of aBatchedSendQueuestructure and to an error message when the batched sends are passed on to the driver.In MTTB-1143 we'd get a send on client ID 0, but that's not a valid client ID in
UnityTransport. My guess is that there's something somewhere (possibly in Boss Room) triggering a send to the server after the connection has closed (which revertsUnityTransport.ServerClientIdto its default value of 0). Of course, ideally there'd never be such a send-after-disconnect and that's what should be ultimately addressed. But the bug is quite hard to reproduce, so as a stopgap until we have something better I'm making a fix that only avoids the last and more user-visible consequences of the issue.Changelog
