Tweening audio volume?

Help and Feedback Scripting Support
#1

It’s me! …again

I have been trying to “animate” a sound to get gradually louder when a certain IntValue in-game is reached. I’m beginning to wonder if it’s even possible to tween volume.
Here’s my script, I really appreciate the help, along with any other advice!

local surge = game.Workspace:WaitForChild("Values"):WaitForChild("SURGE")
local light = script.Parent.SurfaceLight
local buzz = script.Parent
local TweenService = game:GetService("TweenService")

surge.Changed:Connect(function()
	if surge.Value >= 1000 then
		local info = TweenInfo.new(	
			5,
			Enum.EasingStyle.Sine,
			Enum.EasingDirection.Out,
			0,
			false,
			0
		)

		local goals =
		{
		Volume = 10;
		}

		local EarPopper = TweenService:Create(buzz, info, goals)
		wait(1)
		EarPopper:Play()
	end
end)

2 notes:

1.You could instead use a simple for loop if you wanted.

2.I have just tested it out and it works perfect.

local surge = game.Workspace:WaitForChild("Values"):WaitForChild("SURGE")
local buzz = script.Sound
local TweenService = game:GetService("TweenService")

surge.Changed:Connect(function()
	if surge.Value >= 1000 then
		local info = TweenInfo.new(	
			5,
			Enum.EasingStyle.Sine,
			Enum.EasingDirection.Out,
			0,
			false,
			0
		)

		local goals ={Volume = 10}
		local EarPopper = TweenService:Create(buzz, info, goals)
		EarPopper:Play()
	end
end)

Your script seems fine, are you playing the sound in another script? Can you see if the volume is changing?

#4

Every light in the game has this script for the ‘power surge’ event. Yet none of their volumes are changing when it triggers.

#5

Yours works fine? That’s messed up… what did you do exactly? Maybe I have something else that’s not playing along.

#6

Now I got it! Can’t believe it was that simple… just tweaked the coding a little bit. Thanks for the help.

#7

i know this topic is solved and all but im wondering (since i have this same problem) how you would use a for loop for this?

#8

Using a for loop I would do that:

local audio = workspace:WaitForChild("audioName")

for volume = 1, 0, -0.01 do
	audio.Volume = volume
	wait()
end

audio:Stop()

1 is the initial value of volume
0 is the final value that volume will reach
-0.01 is the step value, meaning volume will decrease by 0.01 on each iteration
