It's not allowed to register callbacks for Server from Sector script?

[Rinart73]

I have a script that is attached to sector. And I need to do stuff immediately after player login/logoff.

if onClient() then return end

-- namespace SectorTest
SectorTest = {}

function SectorTest.initialize()
    local server = Server()
    server:registerCallback("onPlayerLogIn", "onPlayerLogIn")
    server:registerCallback("onPlayerLogOff", "onPlayerLogOff")
end

function SectorTest.onPlayerLogIn(playerIndex)
    print("onPlayerLogIn", playerIndex)
end

function SectorTest.onPlayerLogOff(playerIndex)
    print("onPlayerLogOff", playerIndex)
end

 

But when I'm trying to register these callbacks nothing happens when player enters/leaves the game. And if server is launched from bat file, following message appears in server logs:

warning: tried unregistering a callback from server to script mods/ServerGuard/scripts/sector/deferredtest.lua in sector (200:200), which is being generated

 

Why it's not allowed? We can call other Server functions like "isOnline(playerIndex)" from Sector scripts just fine.

 

Of course, I can just check if each player is online/offline every 10 seconds. But it will not produce immediate reponce and will not be performance-friendly.

UPD: Apparently it works if you'll register callbacks after "initialize" function (in first update for example). But why? It's implied that Sector initialize function is called after everything is loaded.

 

if onClient() then return end

local callbacksRegistered = false

-- namespace SectorTest
SectorTest = {}

function SectorTest.updateServer()
    if callbacksRegistered then return end
    local server = Server()
    server:registerCallback("onPlayerLogIn", "onPlayerLogIn")
    server:registerCallback("onPlayerLogOff", "onPlayerLogOff")
    callbacksRegistered = true
end

function SectorTest.onPlayerLogIn(playerIndex)
    print("onPlayerLogIn", playerIndex)
end

function SectorTest.onPlayerLogOff(playerIndex)
    print("onPlayerLogOff", playerIndex)
end

Sorry for poor English.

 

onPlayerLogIn/onPlayerLogOff it is Server callbacks. It is good idia call it from server.lua.

If you want to canch player enternce to sector - try to use Sector():onPlayerEntered() and Sector():onPlayerLeft().

DrMasik, Hi. I disagree. There a plenty of examples when Entity scripts registered Sector callbacks. So why registering Server callbacks from Sector script is incorrect?

No, I specifically need to react when player logins/logoffs.

 

I already found the solution: Server callbacks can be successfully registered in the first update tick.
