Annoying Operator

#1

I am practicing different things in Lua, having learned it in a day and is understandable since I program in different languages. Although, I am unsure why or even how I’ve gotten an error in my code (Issue).

Goal

Whenever it is 14:00:00 or later, or whenever it is 20:00:00 or earlier, a point-light should be “Enabled”.

Issue

The last operator a part of the condition is underlined in ROBLOX Studios.

Concern

Why does the operator not work in this case?

I have tried reading on multiple DevForum posts, as well as reading the Luau language documentation with no luck in finding out a solution to the code error.

while wait() do
		if game.Lighting.ClockTime >= 14 or <= 20 then
		workspace.testPart.PointLight.Enabled = true
		print("Night")
	else
		workspace.testPart.PointLight.Enabled = false
		print("Day")
	end
end

Let me know if I have missed something about the code and feel free to link any external links in assistance to solving the issue.

So here’s the thing, LuaU thinks you want to compare “or” so to fix it you need to do game.Lighting.ClockTime after “or” and after you do that add the operators and stuff you already have addded.

You need to write game.Lighting.ClockTime >= 14 or game.Lighting.ClockTime <= 20 . This is because Lua doesn’t take into account the previous condition when you use “and” or “or”

Try changing:

if game.Lighting.ClockTime >= 14 or <= 20 then

into:

if game.Lighting.ClockTime >= 14 or game.Lighting.ClockTime <= 20 then

code:

while wait() do
		if game.Lighting.ClockTime >= 14 or game.Lighting.ClockTime <= 20 then
		workspace.testPart.PointLight.Enabled = true
		print("Night")
	else
		workspace.testPart.PointLight.Enabled = false
		print("Day")
	end
end

POST UPDATE

These replies have partly solved my issue. My confirmation (prints) are now looping correct, but the point-light has not enabled during the night. 
-- STORED DATA
local newPart = Instance.new("Part") -- variable for part
newPart.Name = "Light" -- name for its use
newPart.Size = Vector3.new(3,3,3) -- 3-dimensional size
newPart.Anchored = true -- locked in space
newPart.Position = Vector3.new(-24.91, 25.984, 21.28) -- 3-dimensional position in space
newPart.Parent = workspace -- child of...


local newLight = Instance.new("PointLight") -- creation of the light source itself
newLight.Parent = newPart -- child of the physical light object

------------------------------------------------------------------
-- PRACTICAL CODE

while wait() do -- loop forever with a 0,03s delay (dedicated light script)
	if game.Lighting.ClockTime >= 18 or game.Lighting.ClockTime <= 4 then -- if hour of day is equal to 18 or 4, or greater than 18 (6 PM) but less than 4 (4 AM)
		newLight.Enabled = true -- light source is enabled
		print("Night") -- confirm enabled source via print
	else
		newLight.Enabled = false -- light source is disabled
		print("Day") -- confirm disabled source via print
	end
end

I was too lazy to add the actual objects through the explorer.

This might look a bit messy with the comments, but in Studios, my custom theme has a very dark color (yet readable) for comments. That means I could have a paragraph for a single print line of code and it would still look clean.

There’s no issue, everything works. The range is too small to be visible, but I can assure you it’s there.

#7

Maybe try adjusting the range and brightness. I’m not sure what Roblox sets those 2 values to when you create a PointLight with Instance.new(), so yeah, try doing something like:

newLight.Brightness = 8
newLight.Range = 16
