In-Game Sounds
In-Game Sounds

In addition to background music, in-game audio can enhance a player’s experience. This course will cover two forms of in-game sounds: positional and feedback sounds.

For the first example, you’ll create a positional sound for a waterfall. In the second example, a script will be used to play a jingle when players touch a collectable.

Positional Sounds

When a Sound object is parented to a part or attachment, it becomes positional. Audio will emit from its location and grow louder as players get closer, as in the case of this waterfall.

Create a Sound

  1. In any desired part, create a new Sound object named WaterfallSound.

  2. In the properties, find SoundId and change it to this waterfall ambience: rbxassetid://6564308795.

    alt

    Custom sounds can be imported using the Asset Manager. Additionally, free sounds uploaded by Roblox and the community can be found using the Toolbox.


  3. For continuous playback when the game starts, toggle Playing and Looped to be on.

  4. Test the game to confirm you hear the waterfall ambience.

Adjust Sound Distance

Notice when testing, the audio plays immediately, even if the player is far away from the object. Using the roll-off properties, you can modify the distance at which a player hears a sound to create fading effects.

  1. Change the RollOffMaxDistance to 30. This property is measured in studs.

    alt

  2. For a smoother fade, change the RollOffMode to InverseTapered. This makes approaching the sound feel less sudden.

    alt

  3. Run the project. Notice how sound is only heard near the object.

    Depending on your needs, you may want to adjust different properties for special effects or increased realism. See the following properties:

    • RollOffMinDistance - Minimum distance (in studs) a sound decreases in volume.
    • SoundGroup - Used to adjust and balance volume between groups of sounds, like background music and in-game effects.

Feedback Sounds

Sounds can be played on command using scripts. You can link sounds to events, such as players touching a part or interacting with a menu. Here, you’ll create a script that plays a chime whenever players touch collectable objects.

Set Up Collectables

The remainder of this course uses a pre-made model. This model includes parts and scripts
so players can collect gemstones.

  1. Download the Collectable Gems model and insert it into Studio.

    alt

    Models can be added into your Inventory to be used between any game

    1. In a browser, open the model page, click the Get button. This adds the model into your inventory.
    2. In Studio, go to the View tab and click on the Toolbox.
    3. In the Toolbox window, click on the Inventory button. Then, make sure the dropdown is on My Models.
    4. Select the Collectable Gems model to add it into the game.

  2. For the collectable chime, in SoundService, create a new Sound named FeedbackSound.

    alt

  3. In FeedbackSound, set the SoundId to rbxassetid://4110925712, a simple chime.

    alt

Setup the Script

  1. In StarterPlayer > StarterPlayerScripts, create a new local script named CollectableSounds.

  2. The code below will run the partTouched function whenever the player touches a collectable. Copy the code into your script.

    local pickupObjects = game.Workspace.Collectables.Objects
    local objectsArray = pickupObjects:GetChildren()
    
    local function partTouched(otherPart, objectPart)
        local whichCharacter = otherPart.Parent
        local humanoid = whichCharacter:FindFirstChildWhichIsA("Humanoid")
    
        if humanoid and objectPart.CanCollide == true then		
                    
        end
    end
    
    -- Binds every object part to the touch function so it works on all parts
    for objectIndex = 1, #objectsArray do
        local objectPart = objectsArray[objectIndex]
        objectPart.Touched:Connect(function(otherPart)
            partTouched(otherPart, objectPart)
        end)
    end

Play a Sound

  1. Create a variable for SoundService, then another variable to store the feedback sound.

    local pickupObjects = game.Workspace.Collectables.Objects
    local objectsArray = pickupObjects:GetChildren()
    
    local SoundService = game:GetService("SoundService")
    local feedbackSound = SoundService:FindFirstChild("FeedbackSound")
    
    local function partTouched(otherPart, objectPart)
  2. To play the chime, find the function partTouched. Within the if statement, call feedbackSound:Play() to play the sound.

    local function partTouched(otherPart, objectPart)
        local whichCharacter = otherPart.Parent
        local humanoid = whichCharacter:FindFirstChildWhichIsA("Humanoid")
    
        -- Play the sound, once finished, destroy the object
        if humanoid and objectPart.CanCollide == true then		
            feedbackSound:Play()		
        end
    end
    
  3. Test the game to confirm that when the player touches a collectable, it both disappears and plays a sound.
