-- Services local Lighting = game:GetService("Lighting") -- Configuration local DAY_LENGTH = 300 -- 5 minutes in seconds -- Variables local startTime = tick() local isDay = true -- Function to update time of day local function updateTimeOfDay() local currentTime = tick() local elapsed = currentTime - startTime if elapsed >= DAY_LENGTH then startTime = currentTime isDay = not isDay end if isDay then Lighting.TimeOfDay = 12 else Lighting.TimeOfDay = 0 end end -- Run the update function every second while true do updateTimeOfDay() wait(1) end

This code creates a day-night cycle in a Roblox game, toggling between daytime and nighttime every 5 minutes. Here's a breakdown of what it does:

  1. Service Reference:
    The Lighting service is accessed from the game using game:GetService("Lighting"). This service controls the environmental lighting in the game.

  2. Configuration: A constant DAY_LENGTH is defined as 300 seconds (representing 5 minutes).

  3. Variables:

    • startTime stores the timestamp (tick() returns the current time in seconds as a UNIX timestamp) when the script starts.
    • isDay (initially true) tracks whether it is currently daytime.
  4. Function: updateTimeOfDay:

    • The function calculates the time elapsed since startTime.
    • If the elapsed time has exceeded DAY_LENGTH (5 minutes), it resets startTime to the current time (tick()), and toggles the isDay variable. This effectively switches between day and night modes.
    • If it's daytime (isDay is true), the Lighting.TimeOfDay is set to 12 (noon).
    • If it's nighttime (isDay is false), the Lighting.TimeOfDay is set to 0 (midnight).
  5. Loop:

    • The while true loop continuously calls the updateTimeOfDay function every second (wait(1)), keeping the day-night cycle running indefinitely.

Summary:

The code alternates the lighting settings between daytime (noon) and nighttime (midnight) in a Roblox game, with each phase lasting 5 minutes. This creates a dynamic 10-minute day-night cycle.
