Lights wont travel through bars [table]

Help and Feedback Scripting Support
#1

Hello, I am trying to make it so when a button is clicked, the lights will turn white from the first bar to the last bar. Problem is, the lights won’t go on or become white, and no errors print in the console.

code;

local WaveI = game.Workspace:WaitForChild("WaveA")
local WaveA = {
	WaveI:WaitForChild("WaveA"):GetDescendants(),
	WaveI:WaitForChild("WaveB"):GetDescendants(),
	WaveI:WaitForChild("WaveC"):GetDescendants(),
	WaveI:WaitForChild("WaveD"):GetDescendants(),
	WaveI:WaitForChild("WaveE"):GetDescendants(),
	WaveI:WaitForChild("WaveF"):GetDescendants(),
	WaveI:WaitForChild("WaveG"):GetDescendants(),
	WaveI:WaitForChild("WaveH"):GetDescendants(),
	WaveI:WaitForChild("WaveI"):GetDescendants(),
	WaveI:WaitForChild("WaveJ"):GetDescendants(),
	WaveI:WaitForChild("WaveJ"):GetDescendants(),
	WaveI:WaitForChild("WaveK"):GetDescendants(),
	WaveI:WaitForChild("WaveL"):GetDescendants(),
	WaveI:WaitForChild("WaveM"):GetDescendants(),
	WaveI:WaitForChild("WaveN"):GetDescendants(),
	WaveI:WaitForChild("WaveO"):GetDescendants(),
	WaveI:WaitForChild("WaveP"):GetDescendants(),
	WaveI:WaitForChild("WaveQ"):GetDescendants(),
	WaveI:WaitForChild("WaveR"):GetDescendants(),
	WaveI:WaitForChild("WaveS"):GetDescendants(),
	WaveI:WaitForChild("WaveT"):GetDescendants(),
	WaveI:WaitForChild("WaveU"):GetDescendants()
}

script.Parent.MouseClick:Connect(function(plr)
	if plr:GetRankInGroup(14407410) >= 200 then
		for _,v in ipairs(WaveA) do
			if (v.ClassName == "Part") then
			v.Color = Color3.fromRGB(255, 255, 255)
				task.wait(0.07)
			end
		end
		for _,v in ipairs(WaveA) do
			if (v.ClassName == "Part") then
				v.Color = Color3.fromRGB(0, 0, 0)
				task.wait(0.07)
			end
		end
	end
end)

and yes, I know this code is very unefficient and can be shortened, but with for loops, etc, it will turn on random lights.

What I am trying to achieve;
(each bar turns black from A to B.)

If no errors or warnings (infinite yeild for instance) are shown them I’m betting your player GetRankInGroup check is failling try printing that out. or none of your waves have descendants.

#3

I have tested the GetRankInGroup function on some scripts, works perfectly, and the waves do have descendants (parts)…

No infinite yield errors pop up when I click the button.

The problem is that these are individual tables, so you would have to go through those too.

local WaveI = game.Workspace:WaitForChild("WaveA")
local WaveA = {
	WaveI:WaitForChild("WaveA"):GetDescendants(),
	WaveI:WaitForChild("WaveB"):GetDescendants(),
	WaveI:WaitForChild("WaveC"):GetDescendants(),
	WaveI:WaitForChild("WaveD"):GetDescendants(),
	WaveI:WaitForChild("WaveE"):GetDescendants(),
	WaveI:WaitForChild("WaveF"):GetDescendants(),
	WaveI:WaitForChild("WaveG"):GetDescendants(),
	WaveI:WaitForChild("WaveH"):GetDescendants(),
	WaveI:WaitForChild("WaveI"):GetDescendants(),
	WaveI:WaitForChild("WaveJ"):GetDescendants(),
	WaveI:WaitForChild("WaveJ"):GetDescendants(),
	WaveI:WaitForChild("WaveK"):GetDescendants(),
	WaveI:WaitForChild("WaveL"):GetDescendants(),
	WaveI:WaitForChild("WaveM"):GetDescendants(),
	WaveI:WaitForChild("WaveN"):GetDescendants(),
	WaveI:WaitForChild("WaveO"):GetDescendants(),
	WaveI:WaitForChild("WaveP"):GetDescendants(),
	WaveI:WaitForChild("WaveQ"):GetDescendants(),
	WaveI:WaitForChild("WaveR"):GetDescendants(),
	WaveI:WaitForChild("WaveS"):GetDescendants(),
	WaveI:WaitForChild("WaveT"):GetDescendants(),
	WaveI:WaitForChild("WaveU"):GetDescendants()
}

script.Parent.MouseClick:Connect(function(plr)
	if plr:GetRankInGroup(14407410) >= 200 then
		for _,tbl in ipairs(WaveA) do
			for _,v in ipairs(tbl) do
				if (v.ClassName == "Part") then
					v.Color = Color3.fromRGB(255, 255, 255)
					task.wait(0.07)
				end
			end
		end
		
		for _,tbl in ipairs(WaveA) do
			for i,v in pairs(tbl) do
				if (v.ClassName == "Part") then
					v.Color = Color3.fromRGB(0, 0, 0)
					task.wait(0.07)
				end
			end
		end
	end
end)

I know, while I was typing the entire table, the quick type thing specifically showed the waves in the WaveA model, and specifically, I also tested this in the command bar, it changed them to white.

Yes, I also tested putting :GetDescendants() into a table and printing the table, and as expected, it returned a table with a table inside.

I see… Tested this once more (with the .Name), it prints nil now…

How would I go over this issue and access the actual parts?

I sent the script in my last post already, but to answer this again, you would need to loop over “v”, which would be the table. Although in my script I renamed it to “tbl” so I wouldn’t have to change much code besides adding another for loop.

local WaveI = game.Workspace:WaitForChild("WaveA")
local WaveA = {
	WaveI:WaitForChild("WaveA"):GetDescendants(),
	WaveI:WaitForChild("WaveB"):GetDescendants(),
	WaveI:WaitForChild("WaveC"):GetDescendants(),
	WaveI:WaitForChild("WaveD"):GetDescendants(),
	WaveI:WaitForChild("WaveE"):GetDescendants(),
	WaveI:WaitForChild("WaveF"):GetDescendants(),
	WaveI:WaitForChild("WaveG"):GetDescendants(),
	WaveI:WaitForChild("WaveH"):GetDescendants(),
	WaveI:WaitForChild("WaveI"):GetDescendants(),
	WaveI:WaitForChild("WaveJ"):GetDescendants(),
	WaveI:WaitForChild("WaveJ"):GetDescendants(),
	WaveI:WaitForChild("WaveK"):GetDescendants(),
	WaveI:WaitForChild("WaveL"):GetDescendants(),
	WaveI:WaitForChild("WaveM"):GetDescendants(),
	WaveI:WaitForChild("WaveN"):GetDescendants(),
	WaveI:WaitForChild("WaveO"):GetDescendants(),
	WaveI:WaitForChild("WaveP"):GetDescendants(),
	WaveI:WaitForChild("WaveQ"):GetDescendants(),
	WaveI:WaitForChild("WaveR"):GetDescendants(),
	WaveI:WaitForChild("WaveS"):GetDescendants(),
	WaveI:WaitForChild("WaveT"):GetDescendants(),
	WaveI:WaitForChild("WaveU"):GetDescendants()
}

script.Parent.MouseClick:Connect(function(plr)
	if plr:GetRankInGroup(14407410) >= 200 then
		for _,tbl in ipairs(WaveA) do
			for i,v in ipairs(tbl) do
				if (v.ClassName == "Part") then
					v.Color = Color3.fromRGB(255, 255, 255)
					task.wait(0.07)
				end
			end
		end
		
		for _,tbl in ipairs(WaveA) do
			for i,v in pairs(tbl) do
				if (v.ClassName == "Part") then
					v.Color = Color3.fromRGB(0, 0, 0)
					task.wait(0.07)
				end
			end
		end
	end
end)

I am now understanding this alot, and it works!
