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.
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
In any desired part, create a new Sound object named WaterfallSound.
In the properties, find SoundId and change it to this waterfall ambience: rbxassetid://6564308795.
Finding Other Sounds
For continuous playback when the game starts, toggle Playing and Looped to be on.
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.
Change the RollOffMaxDistance to 30. This property is measured in studs.
For a smoother fade, change the RollOffMode to InverseTapered. This makes approaching the sound feel less sudden.
Run the project. Notice how sound is only heard near the object.
Fine Tuning the Roll Off
Depending on your needs, you may want to adjust different properties for special effects or increased realism. See the following properties:
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.
Download the Collectable Gems model and insert it into Studio.
How to Add Models
Models can be added into your Inventory to be used between any game
- In a browser, open the model page, click the Get button. This adds the model into your inventory.
- In Studio, go to the View tab and click on the Toolbox.
- In the Toolbox window, click on the Inventory button. Then, make sure the dropdown is on My Models.
- Select the Collectable Gems model to add it into the game.
For the collectable chime, in SoundService, create a new Sound named FeedbackSound.
In FeedbackSound, set the SoundId to rbxassetid://4110925712, a simple chime.
Setup the Script
In StarterPlayer > StarterPlayerScripts, create a new local script named CollectableSounds.
The code below will run the
partTouchedfunction 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
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)
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
Test the game to confirm that when the player touches a collectable, it both disappears and plays a sound.
