X-Post from the Multiplay Hosting Forums page after i realised that my Post actually belongs here.
The Matchmaker only triggers allocations based on matchmaking tickets, so it is not possible to have servers running on standby. Another issue you might run into is that the servers are not intended to be constantly running, so I believe they will shutdown after 24 hours.
For your case you should be able to follow the backfill flow described here.
The matchmaker will create the backfill ticket and will update it when it wants to add tickets to it.
You’ll have to keep approving the backfill ticket and also update it if you detect players leaving.
Thanks for the answer
So basically i would have to try to create backfill tickets using the IP from the server fleet i would like to use? The rest of the workflow would be similar to the normal ticket creation i assume.
The IP that the Game Server will use to create a backfill ticket is its own IP, so it won't change. Game Server Hosting provides a way to get that, see the sample
I see, is there any way to get the allocated server IP + Port on the client side through the matchmake SDK? Maybe only requiring the queue name? Otherwise i guess i would have to save the IP and assigned ports seperately for the client build.
Edit: I misunderstood how the backfill ticket workflow is supposed to work. SO the SERVER creates the backfill ticket and approves it every second, adding incoming players to the Backfill ticket, and updating the backfill ticket with the new client ID's.
Howerver the documentation describes that the incoming clients are connecting OUTSIDE matchmaker. How is that? Don't i always want to use matchmaker to get assigned a fitting server by creating a ticket on the client?
Right, it's only the server that does anything with backfill tickets, never the client.
The "outside the matchmaker" part applies only if you have also have clients that directly connect to the server, bypassing the matchmaker.
If you always use the matchmaker, you don't have to update the backfill ticket when players join, but you DO have to update it when players leave.
