Layout loading:
If you join a room after layout has been loaded, the "finish" signal would be "on actor join" event. You can simply check the current number of players in the room in this handler.
Latency:
To measure round trip time to the server, send an event to yourself (specify client actor id in TargetActors).
The same works for rtt to players. Send and event and reply to it back to sender.
I got it work for waiting for other players, thanks !
But i have another question for this rtt, should i use construct 3 built-in addons like platforminfo plugin to measure rtt of my latency ? then send this latency to myself ? or photon plugin itself has an ability for this ? sorry it's hard to understand for me to measure this rtt..
