SmartAudio
SmartAudio objects are SmartObjects that wrap sound files. Similar to Audio objects, they have many of the same properties and functions.
Properties
| Property Name | Return Type | Description | Tags |
|---|---|---|---|
isPlaying | boolean | Returns if the sound is currently playing. | Read-Only |
isSpatializationEnabled | boolean | Default true. Set to false to play sound without 3D positioning. | Read-Write |
isAttenuationEnabled | boolean | Default true, meaning sounds will fade with distance. | Read-Write |
isOcclusionEnabled | boolean | Default true. Changes attenuation if there is geometry between the player and the audio source. | Read-Write |
isAutoPlayEnabled | boolean | Default false. If set to true when placed in the editor (or included in a template), the sound will be automatically played when loaded. | Read-Only |
isTransient | boolean | Default false. If set to true, the sound will automatically destroy itself after it finishes playing. | Read-Write |
isAutoRepeatEnabled | boolean | Loops when playback has finished. Some sounds are designed to automatically loop, this flag will force others that don't. Useful for looping music. | Read-Write |
pitch | number | Default 1. Multiplies the playback pitch of a sound. Note that some sounds have clamped pitch ranges (0.2 to 1). | Read-Write |
volume | number | Default 1. Multiplies the playback volume of a sound. Note that values above 1 can distort sound, so if you're trying to balance sounds, experiment to see if scaling down works better than scaling up. | Read-Write |
radius | number | Default 0. If non-zero, will override default 3D spatial parameters of the sound. Radius is the distance away from the sound position that will be played at 100% volume. | Read-Write |
falloff | number | Default 0. If non-zero, will override default 3D spatial parameters of the sound. Falloff is the distance outside the radius over which the sound volume will gradually fall to zero. | Read-Write |
fadeInTime | number | Sets the fade in time for the audio. When the audio is played, it will start at zero volume, and fade in over this many seconds. | Read-Write |
fadeOutTime | number | Sets the fadeout time of the audio. When the audio is stopped, it will keep playing for this many seconds, as it fades out. | Read-Write |
startTime | number | The start time of the audio track. Default is 0. Setting this to anything else means that the audio will skip ahead that many seconds when played. | Read-Write |
stopTime | number | The stop time of the audio track. Default is 0. A positive value means that the audio will stop that many seconds from the start of the track, including any fade out time. | Read-Write |
Functions
| Function Name | Return Type | Description | Tags |
