How do I control where my players go, when they enter the room?

ShadowToast

Hi, when my players enter the room I need them to be seated around a table.
I can't use the number of players in the room to pick a seat, because if say there are 3 players and the 2nd one leaves, the next player would technically be the 3rd and would sit on top of the other '3rd' player.
I want them to fill in the gaps in the seating.
Are there any callbacks that happen after all buffered RPC have happened?
Or a way to check if there are any pending rpcs?

Any advice?

Hi @ShadowToast,

Thank you for choosing Photon!

You could use PlayerNumbering UtilityScript if you're using PUN2.
It will assign a player number from 0 to 2 in a room of MaxPlayers = 3.
Just add it to the scene and use extension method player.GetPlayerNumber().

For PUN Classic it's called PlayerRoomIndexing.

JohnTube

does it let someone take the unused number?

This.

JohnTube

It's correct, my bad.
I had assumed the index started from 1.
It actually works and starts from 0.
Check the documentation of the class itself:

indexing ranges from 0 to the maximum number of Players.

I assume this updates when a player leaves? does it move everyones index back that's higher, or does it let someone take the unused number?

@JohnTube When does the number get assigned? I just tested it and found that of 3 players, 2 were assigned number -1 and the third was given 0. FYI I'm trying to use this during 'OnJoinedRoom'.

JohnTube

Good question.
Every time a possible change to the player indexes happen an event is triggered: PlayerNumbering.OnPlayerNumberingChanged but it doesn't tell you what changed or whose player's number changed.

Both -1 and 0 are unexpected values.
-1 means the player index is not set or assigned yet.
0 means the game is in offline mode.

So I would wait for the first occurrence of PlayerNumbering.OnPlayerNumberingChanged after OnJoinedRoom callback. Otherwise, I would keep trying to get the player index until I get a value >= 0.

@JohnTube I made a coroutine to wait for the local players player number to be > 0. It never resolved.
I then attached onto the 'PlayerNumbering.OnPlayerNumberingChanged' to debug the player number.
Every time it was called, it output '0'.
