OneSync Infinity stream (Focus zone)

Is there an event on server side that called when a player enter/exit from another player stream?

… what? The fuck is a ‘player stream’?

Stream = “Focus zone”
“Player ped/vehicle culling. No entities will be created on clients outside a ‘focus zone’, which currently is hardcoded to 300 units around a player. We’re still looking for a better algorithm.”

In the client side the event OnPlayerJoining called from the server when player enter to your stream and the event OnPlayerDropped called from the server when player exit from your stream.
Is there events like that in the server sided?
