What does this mean? (Looping) Its confusing,also its about value

How the script works.

Here is your code,

local minutesAfterMidnight = 0

while true do 
	game.Lighting:SetMinutesAfterMidnight(minutesAfterMidnight) 
	minutesAfterMidnight = minutesAfterMidnight + 1 
	wait(1)
end

There is your script, but how does it work?

This script isn't too complicated. First, the script makes a variable. A variable represents a value. For example,

local x = 5
print(x)

In the above, we set x equal to 5. So when we print 5, it prints 5.

Why do we need local?

The simple answer is, we don't.

Local variables are basically the same as regular variables, but they can't be used outside code. I don't want to go into to, but a good rule of thumb is to always use Local Variables.

After we name something, we don't have to define it again. So we only need to put local in front of new variables.

Example,

local x = "Hello"
print(x)
x = "Goodbye"
print(x)

We only need to use Local Once

The Loop

Loops just run code multiple times. A while loop runs until the value it's looking for is false or nil. Example,

while false do
	print("Won't print")
end

while true do
	print("will print forever")
	wait()
end

---

SetMinutesAfterMidnight

So we have a loop that runs forever, and a variable. If you'll notice, the variable get bigger each time the loop runs, because we're adding 1 to it each time.

What the function SetMinutesAfterMidnight does it it sets the current time to the value, and sets that value to the time in game minutes after midnight.

Another way to write this without variables

There's also a function called :GetMinutesAfterMidnight that we can use.

Example,

while wait(.2) do
	game.Lighting:SetMinutesAfterMidnight(game.Lighting:GetMinutesAfterMidnight()+1)
end

line 2 = game.Lighting:SetMinutesAfterMidnight(game.Lighting:GetMinutesAfterMidnight()+1)

---

What this does

It Sets the number of minutes after midnight to the number of minutes after midnight plus 1.

But how does the loop work? You put a wait.

It's just another way of writing the loop to have a built in delay.

Good Luck!
