How would I make it so that if something is in the workspace nothing will happen, but if something is in workspace something will happen

Currently trying to make so whenever you join a game, nothing will happen, but if you insert something like a Sound in workspace, then something will happen.

Right now I’ve tried everything but it isn’t working. I’m trying to make it so whenever a sound with a certain name is inserted into workspace, the parts will react. But currently whenever I do this and insert a sound into workspace, nothing happens after even though its supposed to work.

Code:

local parts = game.Workspace.Lights:GetChildren("Light")
local Sound = game.Workspace.KMusic -- This should only trigger when the sound appears in workspace but it currently isn't--

Sound:Play()

while Sound.IsPlaying do
	for _, part in next, parts do
		part.Color = Color3.fromRGB(4, 4, Sound.PlaybackLoudness/4);
	end
	wait();
end

If you want to wait for the sound to appear in the workspace before you play it you can do

local Sound = workspace:WaitForChild("KMusic")

This will wait for the sound to appear in the workspace and then continue the script.

#3

Also you can use this:

local Sound

while true do
   local sound = workspace.ChildAdded:Wait()
   if sound.Name == "KMusic" then
      Sound = sound
      break
   end
end
#4

Try this:

local Workspace = game:GetService("Workspace")
local Sound = Workspace:WaitForChild("KMusic")
local parts = Workspace.Lights:GetChildren("Light")

local CertainName = "Certain Name Here"

Workspace.ChildAdded:Connect(function(Child)
    if Child:IsA("Sound") and Child.Name == CertainName then
       Sound:Play()
       while Sound.IsPlaying do
	       for _, part in next, parts do
		       part.Color = Color3.fromRGB(4, 4, Sound.PlaybackLoudness/4);
	       end
	       wait();
       end
    end
end)

It seems there is an Infinite Yield

#6

WaitForChild says infinite yield if it doesn’t find something in 5 seconds, its just a warning to let you know that it could possibly wait forever if the object never shows up. When it does show up the script will continue.

If you want to know when something is added to workspace you can use workspace.ChildAdded event.

workspace.ChildAdded:Connect(function(child) 
	print(child.Name, " was added to workspace")
	
	--Check what is name of child
	if child.Name == "NameOfSound" then 
		--Add code here
		print("Found ",child.Name)
	end
end)

task.wait(10)

--Test adding sound to workspace
local sound = Instance.new("Sound")
sound.Name = "NameOfSound"
sound.Parent = workspace
