Asked By | QonDonion |
so i wanted to generate a sound
and then
( Oscillator::playback is Ref< AudioGeneratorStreamPlayback > )
int emptys = Oscillator::playback->get_frames_available();
that thing →
grrrr >:(
does this
closes the thing!!! for no reasion!!! owwww!!!
no eror
testing with other functions
nope, still closes the thing!!! for no reasion!!! owwww!!!
no eror

Oscillator GDscript:
extends Oscillator
# Called when the node enters the scene tree for the first time.
func _ready():
init()
# Setting mix rate is only possible before play().
play()
# `_fill_buffer` must be called *after* setting `playback`,
# as `fill_buffer` uses the `playback` member variable.
genSine(440)
writeWave()
# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta):
genSine(440)
play()
#writeWave()
My Emotion:
:| what :/ guh :( wh <:( what why
EDITS:
edit1:
i have tried Oscillator::playback.instantiate(); but it still doesn’t the thing!!! for no reasion!!! owwww!!!
no eror
edit2:
what the
it seems like Oscillator::playback.instantiate(); also crashes it
Best guess is that Ref<AudioStreamGeneratorPlayback> playback isn’t initialised (that is, init hasn’t been called by the engine and something is calling writeWave) or that the AudioStreamPlayback object associated with the AudioStreamPlayer (Oscillator) hasn’t been assigned and is returning nullptr.
Confirm it has been assigned and if so, it should be an easy problem to track in the debugger.
