"How do i make it very dark at night?" this means, i want it to get very dark in ambient a night time. heres my code so far.

1 = game:service("Lighting")
while true do
	wait(0.1)
1:SetMinutesAfterMidnight(1:GetMinutesAfterMidnight()+1)

end

as you see i this gives it time. but i want to make the code. better. this code probally has to do with ambinent methods. and so on. i just want to do this at night time. comment oranswer if your confused. or have a answer

answer below me :still doesnt make it very dark. i just need to know what to add AFTER that.. in order to make it very pitch black

1 local time = game:GetService("Lighting") --I used a string other then '1', because I don't think its valid :P 2 while wait(2)do --Loops every 2 seconds 3 if time.TimeOfDay:sub(1,3) == "18:"then --If Lighting's TimeOfDay is 18: o'clock then 4 repeat wait(1/44) --Repeats waiting this amount of time, exactly 0.022727272727273 seconds (used the Studio for the amount of time) 5 time:SetMinutesAfterMidnight(time:GetMinutesAfterMidnight()+0.032) --The script starts changing the TimeOfDay 6 until time.TimeOfDay:sub(1,3) == "05:" --Will stop at 05: o'clock 7 end --The end for the 'if' statement 8 end --The end for the 'while true do end' loop

THATS YOUR ANSWER
