Dynamic sound for the wagon

Help and Feedback Scripting Support
#2

Hello, how are you doing?

If you already have a sound variable with the ID of the sound you would like it to play and the ā€œLoopedā€ is set to true, you can do a while loop and check if the position of the wagon has changed.

If it did, it plays the sound, if it didnā€™t it will stop/donā€™t play the sound

local Wagon = --directory of the wagon goes here, if it's on the workspace you can do game.Workspace.Wagon

local Sound = Wagon.Sound --The sound instance with the ID and Looped set to true.

local Position = Wagon.PrimaryPart.Position --Change the "PrimaryPart" with the name of the part inside the Wagon that you set to be the Primary Part.

Wagon.PrimaryPart.Changed:Connect(function()
	if Position ~= Wagon.PrimaryPart.Position then
		Sound:Play()
		Position = Wagon.PrimaryPart.Position 
	end
end)

while wait(1) do
	if Position == Wagon.PrimaryPart.Position then
		Sound:Stop()
	end
end

If this doesnā€™t works, please reply to my message and tell me which errors there were, iā€™ll try to fix the code.
If you want more information about this, you can search up on the wiki about Position, Sound Parts, CFrame (if you want a more detailed stuff about position and rotation) and Body Velocity, if you want to do it about speed and not about position.

Hope i could help you, have a good day!

Note: The code only will work if the wagon is a model.

No errors are displayed, but the music does not start playing. I will also send a video. maybe iā€™m just stupid lol.

You changed the variable Position to Wagon.Base.Position, but on the Changed and at the while loop itā€™s still Wagon.PrimaryPart.Changed

If this doesnā€™t work, iā€™ll review my code and try to find what is wrong

#5

I fixed my bug,but sound not start playing while wagon moving.

#6

So it wonā€™t play when the wagon starts moving, but a little bit after it does?

#7

no, i can speed up indefinitely, but sound not start playing.

#8

Alright, iā€™ll review my code.
Hopefully i can find what is wrong.

local Wagon = --directory of the wagon goes here, if it's on the workspace you can do game.Workspace.Wagon

local Sound = Wagon.Sound --The sound instance with the ID and Looped set to true.

local Position = Wagon.PrimaryPart.Position --Change the "PrimaryPart" with the name of the part inside the Wagon that you set to be the Primary Part.


while wait(1) do
	if Position == Wagon.PrimaryPart.Position then
		Sound:Stop()
	end
	if Position ~= Wagon.PrimaryPart.Position then
		Sound:Play()
		Position = Wagon.PrimaryPart.Position 
	end
end

Try this out, if it doesnā€™t work add some prints inside the if statements, the while loop and prints of the position variable with the position of the primary part.

#10

if statement print does not give me any output. They donā€™t perceive it as the part moves.

#11

Both of the ifs give no print at all?

#12

No, neither gives output. ā€¦

#13

Are you sure the wagon is at the workspace or anything? It shouldā€™ve printed atleast one thing because the while wait(1) loop shouldā€™ve run.

#14

Yes, the wagon is on the workspace and there have been no outputs since the game started. I tried again but nope.

#15

Thatā€™s really weirdā€¦
Iā€™m not that good in scripting, but according to what i did it shouldā€™ve printed atleast onceā€¦

Sorry if i couldnā€™t help you the way you wanted, but if you want more information you can click here, here and here if you still want to fix the problem

Again, iā€™m sorry i couldnā€™t fix your problem and i think thereā€™s nothing more i can do. Have a good day.

However, thank you for your support! :slight_smile:

The reason the code suggested by @TrashMakeRice isnā€™t working for you is that you already have a while-true-do loop at the start of your code. Also, the .Changed event doesnā€™t fire on physics-related changes (like position, cframe, velocity).
I attempted to edit the script to make it work in this scenario, but I havenā€™t tested it myself. I will post it here in a second.

Now that you mentioned it, i noticed the while true do part, i literally have no idea why i didnā€™t notice that part.

I had no idea .Changed didnā€™t work on those things, i thought it was when anything of all the partā€™s property changed, thanks for letting me know!

This is the script I came up with:

local Audio = script.Parent

local speed = 0

local DriveSound = Audio:WaitForChild("DriveSound")

local Sound = Audio:WaitForChild("Sound")

Sound.Looped = true

DriveSound.Looped = true

while true do
	wait()

	speed = Audio.Velocity.Magnitude
	
	if speed >= 1 and (DriveSound.Playing == false or Sound.Playing == false) then
		
		DriveSound:Play()
		Sound:Play()
		
	else
		
		if speed < 1 then
			
			DriveSound:Stop()
			Sound:Stop()
			
		end
		
	end
	
	DriveSound.PlaybackSpeed = speed/100 + 0.1
	Sound.PlaybackSpeed = speed/100 + 0.1
	Sound.Volume = speed/100 + 0.1

end

Yes, this is exactly the desired result. Thank you all for your support! :slight_smile:
