Methods

Method Descriptions

int _get_loop_count() virtual const 🔗

Overridable method. Should return how many times this audio stream has looped. Most built-in playbacks always return 0.

Variant _get_parameter(name: StringName) virtual const 🔗

Return the current value of a playback parameter by name (see AudioStream._get_parameter_list).

float _get_playback_position() virtual const 🔗

Overridable method. Should return the current progress along the audio stream, in seconds.

bool _is_playing() virtual const 🔗

Overridable method. Should return true if this playback is active and playing its audio stream.

int _mix(buffer: AudioFrame*, rate_scale: float, frames: int) virtual 🔗

Override this method to customize how the audio stream is mixed. This method is called even if the playback is not active.

Note: It is not useful to override this method in GDScript or C#. Only GDExtension can take advantage of it.

void _seek(position: float) virtual 🔗

void _set_parameter(name: StringName, value: Variant) virtual 🔗

void _start(from_pos: float) virtual 🔗

Override this method to customize what happens when the playback starts at the given position, such as by calling AudioStreamPlayer.play.

void _stop() virtual 🔗

Override this method to customize what happens when the playback is stopped, such as by calling AudioStreamPlayer.stop.

void _tag_used_streams() virtual 🔗

Overridable method. Called whenever the audio stream is mixed if the playback is active and AudioServer.set_enable_tagging_used_audio_streams has been set to true. Editor plugins may use this method to “tag” the current position along the audio stream and display it in a preview.

AudioSamplePlayback get_sample_playback() const 🔗

Experimental: This method may be changed or removed in future versions.

Returns the AudioSamplePlayback associated with this AudioStreamPlayback for playing back the audio sample of this stream.
