🎒 Examples

local my_sound = Sound(
    Vector(-510, 145, 63), -- Location (if a 3D sound)
    "nanos-world::A_VR_Confirm", -- Asset Path
    false, -- Is 2D Sound
    true, -- Auto Destroy (if to destroy after finished playing)
    SoundType.SFX,
    1, -- Volume
    1 -- Pitch
)

-- Spawning a ogg sound located in a Package
local ogg_sound = Sound(Vector(), "package://my-package/Client/awesome_beep.ogg", true)

🛠 Constructors

Normal

local my_sound = Sound(location, asset, is_2D_sound?, auto_destroy?, sound_type?, volume?, pitch?, inner_radius?, falloff_distance?, attenuation_function?, keep_playig_when_silent?, loop_mode?)

Type	Name	Default	Description
Vector	location		Only used if 3D sound
Sound Reference	asset		The Sound Asset to load
boolean	is_2D_sound	false	Whether to spawn it as 2D or 3D
boolean	auto_destroy	true	Whether to destroy after finished playing
SoundType	sound_type	SoundType.SFX	Used to apply user's volume settings
float	volume	1
float	pitch	1
float	inner_radius	400	Only used if 3D sound
float	falloff_distance	3600	Only used if 3D sound
AttenuationFunction	attenuation_function	Linear	Only used if 3D sound
boolean	keep_playig_when_silent	false	Only used if 3D sound - Use with caution, it may cause performance issues!
SoundLoopMode	loop_mode	Default	Whether should force sound to loop

Note

auto_destroy means the Entity will be immediately destroyed after spawned, losing references to the Particle System spawned in-game. So if the Particle System itself loops indefinitely, it will keep playing until the Player reconnects.

🔊 Sound Attenuation

This property defines the function that determines the rate of attenuation over distance. There are a number of different functions to choose from:

🔈 Linear

This is the default function. When using this function the volume will attenuate linearly and so the changes in volume are constant as the listener moves towards and away from the source. This function is good for crossfading between large background-type sounds that don't need tightly focussed 3D spatial falloff settings.

🔈 Logarithmic

When using this function the volume attenuates such that the changes in volume are greater at close distances, and lesser at far distances. This function is good for spot sounds that need good 3D positioning, while still being audible at reasonable distances.

🔈 Inverse

When using this function, the changes in volume are similar to that of the logarithmic curve, but are more exaggerated. This function is good for sounds that only need to be just audible at far distances, but that gets significantly louder as the listener gets quite close to the source.

🔈 Log Reverse

When using this function, the changes in volume are lesser at close distances, with more dramatic differences at far distances. This function is good for sounds that need to be loud across larger distances.

🔈 Natural Sound

This function attempts to model a more 'naturalistic' falloff behavior to produce behaviors that closer match reality. This function is a kind of 'middle ground' between the Logarithmic and Inverse functions.
