Lobby start

[Mrfull]

How to launch game when all players connect to teams?

[DEV-ONI]

It is in the documentation:
https://dota2.readthedocs.io/en/stable/dota2.features.lobby.html#dota2.features.lobby.Lobby.launch_practice_lobby

As for checking if all players have joined, you have to implement that yourself, perhaps by checking the all_members repeated
proto field on the a lobby events:

dota2/protobufs/dota_gcmessages_common_match_management.proto

Line 348 in 3ca4c43

repeated dota.CSODOTALobbyMember all_members = 120;

I suggest printing out or logging the proto messages you get so you can see what information they carry as you experiment with them.
