Step.1 = In Explorer, right-click on ServerScriptService and select Script. 

1. Rename the script to "DayNightCycle" if you'd like. 

2. Step.2 = in the script copy and paste this (ctrl+c copy/ctrl+v paste)

3. SCRIPT (dont copy this word)

4. local Lighting = game:GetService("Lighting")

5. 
   

6. -- Customize cycle length in seconds

7. local dayDuration = 600  -- Full cycle duration (10 minutes here)

8. 
   

9. -- Set up initial conditions

10. Lighting.ClockTime = 6  -- Starts at morning (6 AM)

11. 
    

12. while true do

13.     -- Advance the clock time based on the duration of the cycle

14.     Lighting.ClockTime = (Lighting.ClockTime + (24 / dayDuration)) % 24

15. 
    

16.     -- Adjust other Lighting properties if desired

17.     if Lighting.ClockTime >= 6 and Lighting.ClockTime < 18 then

18.         -- Daytime settings

19.         Lighting.Brightness = 2

20.         Lighting.OutdoorAmbient = Color3.fromRGB(255, 255, 255)

21.     else

22.         -- Nighttime settings

23.         Lighting.Brightness = 0.5

24.         Lighting.OutdoorAmbient = Color3.fromRGB(50, 50, 80)

25.     end

26. 
    

27.     -- Wait a short interval to make the cycle smooth

28.     wait(1)  -- Adjust to control cycle smoothness

29. end

Explanation of the Script

• dayDuration is the length of the full day-night cycle in seconds. You can adjust this value to make the cycle faster or slower.

• Lighting.ClockTime is adjusted continuously, making the time of day move forward.

• Lighting.Brightness and Lighting.OutdoorAmbient settings change depending on whether it's day or night, allowing for different appearances.

Optional Adjustments

• Cycle Duration: Increase dayDuration for a slower cycle or decrease it for a faster one.

• Lighting Properties: Customize Brightness, OutdoorAmbient, or even add effects like fog during night hours to enhance the atmosphere.

• you can change the time in day duration 

Step 1: Create the Animation

1. Open Roblox Studio and go to the Plugins tab.

2. Select Animation Editor.

3. Select the rig (make sure it’s an R6 or R15 rig that’s compatible with animations).

4. Use the Animation Editor to create your animation. Once you’re done, name and save the animation.

5. Export the animation and save the Animation ID that Roblox gives you.

Step 2: Script the Animation Loop

1. In Explorer, add a Script under the rig (or in ServerScriptService if you’re playing it on a character).

2. Here’s a sample script to loop the animation:

3. local rig = script.Parent  -- Make sure this points to your rig

4. local animation = Instance.new("Animation")

5. animation.AnimationId = "rbxassetid://YOUR_ANIMATION_ID"  -- Replace with your animation ID

6. 
   

7. local animator = rig:FindFirstChild("Animator") or rig:WaitForChild("Humanoid"):WaitForChild("Animator")

8. local animationTrack = animator:LoadAnimation(animation)

9. 
   

10. -- Set looped and play the animation

11. animationTrack.Looped = true  -- Ensures the animation will repeat

12. animationTrack:Play()  -- Start the animation

13. 
    

1. Using Default Player Animations

By default, Roblox provides basic animations for jumping, falling, walking, running, climbing, and idle. These are automatically applied to characters in most games.

2. Replacing Default Animations

If you want custom animations, you can replace the default ones using an AnimationController and a Script. Here’s how:

• Find/Create the Animation IDs:

  1. If you want to use custom animations, create your own using Roblox Studio’s Animation Editor or find animations in the Toolbox. Each animation has a unique ID, which you’ll need.

• Insert the Animations:

  1. Open StarterPlayer in the Explorer panel.

  2. Insert a LocalScript inside StarterPlayerScripts (this will ensure the script runs on each player).

  3. In the LocalScript, use the following template to load custom animations: 

  4. -- Animation IDs

  5. local runAnim = "rbxassetid://RunAnimationID"

  6. local jumpAnim = "rbxassetid://JumpAnimationID"

  7. local fallAnim = "rbxassetid://FallAnimationID"

  8. local walkAnim = "rbxassetid://WalkAnimationID"

  9. 
     

  10. -- Replace default animations

  11. local function replaceAnimation(animName, animID)

  12.     local humanoid = game.Players.LocalPlayer.Character:WaitForChild("Humanoid")

  13.     local anim = Instance.new("Animation")

  14.     anim.Name = animName

  15.     anim.AnimationId = animID

  16.     

  17.     -- Override the humanoid's animation

  18.     humanoid:FindFirstChildOfClass("Animator"):LoadAnimation(anim)

  19. end

  20. 
      

  21. replaceAnimation("WalkAnim", walkAnim)

  22. replaceAnimation("RunAnim", runAnim)

  23. replaceAnimation("JumpAnim", jumpAnim)

  24. replaceAnimation("FallAnim", fallAnim)

  25. 
      

3. Creating Custom Animations in Roblox Studio

To make your own animations, use the Animation Editor:

• Open the Animation Editor by selecting it from the Plugins tab.

• Select a Rig (e.g., BlockRig or R15 Rig) to animate.

• Create frames to animate movements like walking, jumping, or running.

• Save and upload your animation to get an Animation ID.

4. Testing the Animations

• After adding or replacing animations, click Play in Roblox Studio to test the animations in your game.

• Ensure all animations transition smoothly between actions like running to jumping or walking to idle.
