Need help adding sound to disappearing stairs script

[Calum_Dev (Calum)]

I made a disappearing stairs script but when I added sound, it broke the code. The reason I think it broke the code is because not every stair has sound in it. Is it possible to check if the staircase has a sound object inside it before attempting to play and if it doesn’t it just moves on and makes the stair disappear?

for i,stair in pairs(game.Workspace.Stairs:GetChildren()) do 
	local sound = stair.Sound
	
	local ogSize = stair.Size
	local TweenService = game:GetService("TweenService")
	
	local tweenInfo = TweenInfo.new(
		0.8, -- The time the tween takes to complete
		Enum.EasingStyle.Linear, -- The tween style.
		Enum.EasingDirection.InOut, -- EasingDirection
		0, -- How many times you want the tween to repeat. If you make it less than 0 it will repeat forever.
		false, -- Reverse
		0 -- Delay
	)
	
	local Tween = TweenService:Create(stair, tweenInfo, {Size = Vector3.new(0,0,0)})
	local Tween2 = TweenService:Create(stair, tweenInfo, {Transparency = 1})
	local Tween3 = TweenService:Create(stair, tweenInfo, {Size = ogSize})
	local Tween4 = TweenService:Create(stair, tweenInfo, {Transparency = 0})
	
	function onTouched(hit)
		sound:Play()
		wait(0.05)
		Tween:Play()
		Tween2:Play()
		Tween.Completed:Wait()
		wait(5)
		Tween3:Play()
		Tween4:Play()
		Tween3.Completed:Wait()
		end
	stair.Touched:connect(onTouched)
end

I am working this out for you and so far I’ve found something of a fix.

for i,stair in pairs(game.Workspace.Stairs:GetChildren()) do 
	local ogSize = stair.Size
	local TweenService = game:GetService("TweenService")

	local tweenInfo = TweenInfo.new(
		0.8, -- The time the tween takes to complete
		Enum.EasingStyle.Linear, -- The tween style.
		Enum.EasingDirection.InOut, -- EasingDirection
		0, -- How many times you want the tween to repeat. If you make it less than 0 it will repeat forever.
		false, -- Reverse
		0 -- Delay
	)

	local Tween = TweenService:Create(stair, tweenInfo, {Size = Vector3.new(0,0,0)})
	local Tween2 = TweenService:Create(stair, tweenInfo, {Transparency = 1})
	local Tween3 = TweenService:Create(stair, tweenInfo, {Size = ogSize})
	local Tween4 = TweenService:Create(stair, tweenInfo, {Transparency = 0})

	function onTouched(hit)
		if stair:FindFirstChild('Sound') then
			stair.Sound:play()
		end
		wait(0.05)
		Tween:Play()
		Tween2:Play()
		Tween.Completed:Wait()
		stair.CanTouch = false
		wait(5)
		Tween3:Play()
		Tween4:Play()
		Tween3.Completed:Wait()
		stair.CanTouch = true
	end
	stair.Touched:connect(onTouched)
end

I have removed the local establishing the sound, line 2.
And after function onTouched(hit), I removed sound:Play(), then replaced it with a little FindFirstChild check.

I have also added lines that disable and enable CanTouch after the tweens complete, so the sound doesn’t get played if the player manages to touch the stair after it disappears.

I have very little scripting knowledge, as I am a beginner, so this is also a learning experience for me, so far this seems to work in testing.

This works perfectly! Thanks so much, you’re very talented for a “beginner”!!
