AudioStreamPlayer2D¶

Inherits: Node2D < CanvasItem < Node < Object

Plays positional sound in 2D space.

Description¶

Plays audio that dampens with distance from screen center.

See also AudioStreamPlayer to play a sound non-positionally.

Note: Hiding an AudioStreamPlayer2D node does not disable its audio output. To temporarily disable an AudioStreamPlayer2D's audio output, set volume_db to a very low value like -100 (which isn't audible to human hearing).

Signals¶

finished ( )

Property Descriptions¶

int area_mask

Default	`1`
Setter	set_area_mask(value)
Getter	get_area_mask()

Areas in which this sound plays.

float attenuation

Default	`1.0`
Setter	set_attenuation(value)
Getter	get_attenuation()

Dampens audio over distance with this as an exponent.

bool autoplay

Default	`false`
Setter	set_autoplay(value)
Getter	is_autoplay_enabled()

If true, audio plays when added to scene tree.

String bus

Default	`"Master"`
Setter	set_bus(value)
Getter	get_bus()

Bus on which this audio is playing.

float max_distance

Default	`2000.0`
Setter	set_max_distance(value)
Getter	get_max_distance()

Maximum distance from which audio is still hearable.

float pitch_scale

Default	`1.0`
Setter	set_pitch_scale(value)
Getter	get_pitch_scale()

The pitch and the tempo of the audio, as a multiplier of the audio sample's sample rate.

bool playing

Default	`false`
Getter	is_playing()

If true, audio is playing.

AudioStream stream

Setter	set_stream(value)
Getter	get_stream()

The AudioStream object to be played.

bool stream_paused

Default	`false`
Setter	set_stream_paused(value)
Getter	get_stream_paused()

If true, the playback is paused. You can resume it by setting stream_paused to false.

float volume_db

Default	`0.0`
Setter	set_volume_db(value)
Getter	get_volume_db()

Base volume without dampening.

Method Descriptions¶

float get_playback_position ( )

Returns the position in the AudioStream.

AudioStreamPlayback get_stream_playback ( )

Returns the AudioStreamPlayback object associated with this AudioStreamPlayer2D.

void play ( float from_position=0.0 )

Plays the audio from the given position from_position, in seconds.

void seek ( float to_position )

Sets the position from which audio will be played, in seconds.

void stop ( )

Stops the audio.
