I have a problem with the sfx of nightvision as it is in the lecture.

In the “Nightvision Mode” section, you proposed loading the stream from disk every time you want to play it, and that makes the sound “late”.

The solution is to load the sfx in the _ready function, so setting the stream and stating playing is instantaneous.

For example, my code in VisionMode.gd is as follows:

extends CanvasModulate

const VISION_DARK=Color("504279")
const VISION_NIGHTVISION=Color("65a47e")

var nightvision_on_sfx=load(Global.nightvision_on_sfx)
var nightvision_off_sfx=load(Global.nightvision_off_sfx)

func _ready():
    add_to_group("interface")
    set_vision_dark()

func set_vision_dark():
    color=VISION_DARK
    play(nightvision_off_sfx)

func set_vision_nightvision():
    color=VISION_NIGHTVISION
    play(nightvision_on_sfx)

func play(streamdata):
    $AudioStreamPlayer.stream=streamdata
    $AudioStreamPlayer.play()
