🎒 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?)
TypeNameDefaultDescription
Vectorlocation Required parameter Only used if 3D sound
Sound Referenceasset Required parameter The Sound Asset to load
booleanis_2D_soundfalseWhether to spawn it as 2D or 3D
booleanauto_destroytrueWhether to destroy after finished playing
SoundTypesound_typeSoundType.SFXUsed to apply user's volume settings
floatvolume1No description provided
floatpitch1No description provided
floatinner_radius400Only used if 3D sound
floatfalloff_distance3600Only used if 3D sound
AttenuationFunctionattenuation_functionLinearOnly used if 3D sound
booleankeep_playig_when_silentfalseOnly used if 3D sound - Use with caution, it may cause performance issues!
SoundLoopModeloop_modeDefaultWhether 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.
