Pomoc z skryptem.

Dzień dobry, 

ostatnio próbowałem napisać skrypt, ale coś mi nie wychodzi jeżeli jest taka opcja, to prosił bym bardzo o pomoc.

skrypt:

options:
  title_verification: "&4&lWeryfikacja..."
  title_ready: "&aGotowe!"
  message_blocked: "&cSerwer jest zamknięty, więcej informacji na: &nhttps://discord.gg/bWR7YGmZkw"

variables:
  {_server_status} = "otwarty"

on join:
  send title "{@title_verification}" with subtitle "" for 5 seconds to player
  cancel event
  set player's can fly to false
  set player's can use commands to false
  set player's can chat to false
  wait 5 seconds
  if {_server_status} is "zamknięty":
    kick player due to "{@message_blocked}"
  else:
    send title "{@title_ready}" with subtitle "" for 2 seconds to player
    set player's can fly to true
    set player's can use commands to true
    set player's can chat to true

command /zamknij:
  trigger:
    set {_server_status} to "zamknięty"
    broadcast "Serwer został zamknięty."

command /otworz:
  trigger:
    set {_server_status} to "otwarty"
    broadcast "Serwer został otwarty."
