AudioSource
Vaelis 1.0.0 AudioSource component reference: fields, script API, behavior and examples.
#What it does
Play a local audio asset, optionally with distance-based 3D attenuation.
#How to add and use AudioSource
Editor path: Select the target entity in the Hierarchy (left side) → look at the Inspector (right side) → click Add Component at the bottom of the Inspector → search for AudioSource → click the component row. The Add Component picker is a centered modal with a search box; it only lists components not already attached.
For components with a dedicated editor tool, the tool is opened or activated from the location described below. Do not assume that adding the component alone activates its editor; some systems require a separate window, panel, or viewport tool.
#Component setup & editor tools
- Select entity → Inspector → Add Component → Audio Source. Assign an imported audio asset in the AudioSource section and use the script API for playback/state control.
#What you should see after adding it
The component appears as its own section in the Inspector. Its serialized settings are listed in the Component data table below. If a field is conditional, it appears only when the relevant mode/type is selected. If a field is a runtime state field (for example grounded or resolved velocity), treat it as read-only diagnostic state unless the API reference explicitly documents it as writable.
#How to read the settings
For every setting below, the documentation distinguishes type, default, meaning, and tuning direction where behavior is known. When a value represents a direction, use the engine's coordinate convention documented in Coordinate system; do not substitute Unity/Godot conventions.
#Component data
| Field | Type | Purpose | Default |
|---|---|---|---|
audioKey | string|null | Audio asset key. | null |
is3D | boolean | Enable distance attenuation. | false |
volume | number | Volume 0-1. | 1 |
pitch | number | Pitch multiplier; runtime API clamps to 0.25-4. | 1 |
loop | boolean | Loop playback. | true |
autoplay | boolean | Play automatically. | true |
minDistance | number | Full-volume distance for 3D audio. | 100 |
maxDistance | number | Silent distance for 3D audio. | 600 |
#Tuning behavior
These are the practical direction-of-change rules for the most important controls on this component.
| Setting | What changing it does |
|---|---|
volume | 0 silent; 1 the base configured level. |
pitch | 1 normal playback speed; >1 faster/higher; <1 slower/lower. |
minDistance | 3D only: inside this radius the source remains at full base volume. |
maxDistance | 3D only: beyond this radius the source is silent. |
#Script API
| Member | Kind | Description |
|---|---|---|
play() | Method | Start/restart playback. |
playOnce() | Method | Play without persistent looping. |
stop() | Method | Stop playback. |
volume | Property | Volume 0-1. |
pitch | Property | Pitch multiplier. |
playing | Property | Read-only playback state. |
#Examples
this.audio.playOnce();this.audio.volume = 0.5;
