Server side blueprint scripting

Ive got a quick question as im not entirely sure how to handle this.

What would be the best way going about finding out when a new player has joined the server?

Im having trouble visualising where this would take place and how to capture it as i cant find any nodes that provide this information on demand.

there is a “PostLogin” Node in GameMode. however it provides no informations about the new player

Thanks thats perfect.

I wish there was a master list of all nodes and a description of each in the documentation.

Is there a similar Node that notifies when a player has disconnected?

Hello,
Maybe new node made by Rama for 4.6 may help you too : From Me For You in the Latest Engine Release - Blueprint Visual Scripting - Unreal Engine Forums by registering users in a “logged” bool array and checking if true or false with id as index for example.
