Sounds — giving the world a voice

A game with no sound feels like a movie with the volume off. Sounds are objects — you create them, give them audio to play, and trigger them at exactly the right moment.

#Creating a sound

A Sound object needs a SoundId (the audio file) before it can play:

local sound = Instance.new("Sound")
sound.SoundId = "rbxassetid://123456789" -- a real sound ID
sound.Volume = 0.5
sound.Parent = part
sound:Play()

• SoundId — which audio file. Sound IDs look like rbxassetid://123456. Upload your own audio to your account (or use free ones from the toolbox), copy its ID, and paste it. The placeholder number above won't play anything — swap in a real ID.
• Volume — how loud (0 to 1).
• :Play() — start it.

#Playing where it's heard

Here's the catch: sounds are heard per-player. A :Play() on the server is silent to clients unless it's replicated — and that's a mess you don't need.

For feel-effects — a coin pop, a button click, a jump — play them on the client:

-- LocalScript
coin.ClickDetector.MouseClick:Connect(function()
    coin.Sound:Play() -- you'll hear it on your own client
    clickEvent:FireServer()
end)

The coin sound is feel, and feel is per-player. So it fires client-side, while the coin reward stays server-side. One click, two layers.

#Stopping and controlling

Sounds have the usual controls:

sound:Stop()          -- stop playing
sound:SetAttribute("Playing", false) -- your own flag, if you like

For looping ambient audio — wind, waves, a busy street — set sound.Looped = true before :Play(). One sound object can loop forever until you :Stop() it.

coin.ClickDetector.MouseClick:Connect(function()
-- play the pickup sound
clickEvent:FireServer()
end)

#Common mistakes

• Using a fake SoundId. rbxassetid://123456 plays nothing. Use a real ID from the toolbox or your own upload.
• Playing on the server. Per-player feel-effects belong in LocalScripts, or they're silent to the player who triggered them.
• Forgetting the Parent. A Sound with no parent plays nowhere. Parent it to the part or the GUI.
• Expecting sounds to loop by default. Set Looped = true for ambient audio.
