<method name="_get_beat_count" qualifiers="virtual const">
|
|
<return type="int" />
|
|
<description>
|
|
Overridable method. Should return the total number of beats of this audio stream. Used by the engine to determine the position of every beat.
|
|
Ideally, the returned value should be based off the stream's sample rate ([member AudioStreamWAV.mix_rate], for example).

<description>
|
|
Overridable method. Should return the tempo of this audio stream, in beats per minute (BPM). Used by the engine to determine the position of every beat.
|
|
Ideally, the returned value should be based off the stream's sample rate ([member AudioStreamWAV.mix_rate], for example).

<method name="_get_parameter_list" qualifiers="virtual const">
|
|
<return type="Dictionary[]" />
|
|
<description>
|
|
Return the controllable parameters of this stream. This array contains dictionaries with a property info description format (see [method Object.get_property_list]). Additionally, the default value for this parameter must be added tho each dictionary in "default_value" field.

|
<return type="AudioStreamPlayback" />
|
|
<description>
|
|
Override this method to customize the returned value of [method instantiate_playback]. Should returned a new [AudioStreamPlayback] created when the stream is played (such as by an [AudioStreamPlayer])..

<method name="_is_monophonic" qualifiers="virtual const">
|
|
<return type="bool" />

<method name="instantiate_playback">
|
|
<return type="AudioStreamPlayback" />
|
|
<description>
|
|
Returns a newly created [AudioStreamPlayback] intended to play this audio stream. Useful for when you want to extend [method _instantiate_playback] but call [method instantiate_playback] from an internally held AudioStream subresource. An example of this can be found in the source code for [code]AudioStreamRandomPitch::instantiate_playback[/code].
