How would I go on about traveling lights?

Hello, how would I go on about making a traveling light?

E.g:
(video from OAS3)

  • p.s: im talking about the spotlights, they go from a top to bottom order.

I tried using for loops, it did work, but it turned off random spotlights, and not from a top to bottom style order.

You could try to use tween service to change their orientation

You should use your for loop, but sort the table by whatever criteria you want. For example, by Y position:

local lights = something:GetChildren()

local function SortFunc(a, b)
  return a.Position.Y < b.Position.Y -- your sorting criteria
end

table.sort(lights, SortFunc)

-- now do your for loop

I tested this on another place, it worked. But when I test it in the main game, it will not work, I have tried using the table, etc.

Code;

task.wait(1)
local beams = {}
for i,v in pairs(game.Workspace:WaitForChild("GroundSpotLights"):GetDescendants()) do
	if v:IsA("Beam") then
		table.insert(beams, v)
	end
end

local function sort(a, b)
	return a.Position.X < b.Position.X
end

table.sort(beams, sort)

local function tween(object, goals, timer)
	local tween = game:GetService("TweenService"):Create(object, TweenInfo.new(timer, Enum.EasingStyle.Sine, Enum.EasingDirection.Out, 0, false, 0), goals)
	tween:Play()
	tween.Completed:Wait()
	tween:Destroy()
end

script.Parent.MouseClick:Connect(function(plr)
	if plr.UserId == 2407693045 then
			for _, l in pairs(beams) do
			pcall(function()
				if l:IsA("Beam") then
					l.Enabled = true
					task.wait(.001)
				end
			end)
		end
				tween(game.Workspace:WaitForChild("Lighting"), {Color = Color3.fromRGB(175, 175, 175)}, .25)
				task.wait(.025)
				tween(game.Workspace:WaitForChild("Lighting"), {Color = Color3.new(0,0,0)}, .25)
		else
			plr:Kick("DENIED")
	end
end)

Change pairs to ipairs to iterate through in order.

Just now tried that. Same error…

new code;

task.wait(1)
local beams = {}
for i,v in pairs(game.Workspace:WaitForChild("GroundSpotLights"):GetDescendants()) do
	if v:IsA("Beam") then
		table.insert(beams, v)
	end
end

local function sort(a, b)
	return a.Position.X < b.Position.X
end

table.sort(beams, sort)

local function tween(object, goals, timer)
	local tween = game:GetService("TweenService"):Create(object, TweenInfo.new(timer, Enum.EasingStyle.Sine, Enum.EasingDirection.Out, 0, false, 0), goals)
	tween:Play()
	tween.Completed:Wait()
	tween:Destroy()
end

script.Parent.MouseClick:Connect(function(plr)
	if plr.UserId == 2407693045 then
			for _, l in ipairs(game.Workspace:WaitForChild("GroundSpotLights"):GetDescendants()) do
			pcall(function()
				if l:IsA("Beam") then
					l.Enabled = true
					task.wait(.001)
				end
			end)
		end
				tween(game.Workspace:WaitForChild("Lighting"), {Color = Color3.fromRGB(175, 175, 175)}, .25)
				task.wait(.025)
				tween(game.Workspace:WaitForChild("Lighting"), {Color = Color3.new(0,0,0)}, .25)
		else
			plr:Kick("DENIED")
	end
end)

So the way to approach this is as following.

  • Make a Lights folder.
  • Make a Childfolder for each wave/line of light you want tweened. Name each Childfolder in order, from 1 to how many lines/waves of lights you have.
  • Put one or multiple lights into these Childfolders.

and then you just loop through it all!

local LightsFolder = workspace:WaitForChild("LightsFolder")

for Count = 1, #LightsFolder:GetChildren() do
	local ChildFolder = LightsFolder:FindFirstChild(Count)
	if ChildFolder then
		for _, Light in pairs(ChildFolder:GetChildren()) do
			if Light:IsA("Pointlight") or Light:IsA("SurfaceLight") or Light IsA("Spotlight") then
				-- TWEEN STUFF for each light!
			end
		end
	end
end

and if you want the loop to go backwards, just do this

for Count  = #LightsFolder:GetChildren(), 1, -1 do
	local ChildFolder = LightsFolder:FindFirstChild(Count)
	if ChildFolder then
		for _, Light in pairs(ChildFolder:GetChildren()) do
			if Light:IsA("Pointlight") or Light:IsA("SurfaceLight") or Light IsA("Spotlight") then
				-- TWEEN STUFF for each light!
			end
		end
	end
end

Personally I use this method a lot, if I want to sort tweened stuff. I could go by sorting a table by any value like position.y, but with my method, you can go way beyond and make a huge neon palm tree, that will turn on/off the lights in the order you want them to.

Just tried that, it couldn’t get the children of an index. So I then tried LightsFolder:GetChildren()). It worked, but it wasn’t in order…

#9

Tried testing that on a place, it works, but in my game, it doesn’t. So I will go ahead and re write the code to see if it will fix.

#10

This should use the sorted beams table. It shouldn’t make a new one—then you’ve lost all the sorted-ness!

for _, l in pairs(beams) do
#11

I know, I re-wrote the code now, and it works!

Thanks

I wrote a part of it wrong, it’s updated now.
