Godot - Get Tween animation playback time

GDScript code example to get Tween animation playback time.

get_total_elapsed_time() can get Tween animation playback time.

The get_total_elapsed_time() return value is in seconds, and does not include pause() suspend time.

It is also affected by speed changes from set_speed_scale().
For example, if set to 10x speed with set_speed_scale(), the get_total_elapsed_time() return value will be 10 times the actual elapsed time.

var tween = create_tween().set_loops()

func _ready():
	tween.tween_property(self, "modulate", Color( 1, 1, 1, 0), 0.5)
	tween.tween_property(self, "modulate", Color( 1, 1, 1, 1), 0.5).set_delay(0.5)
	tween.play()

func _physics_process(_delta):
	var tween_playtime = tween.get_total_elapsed_time()
	print(tween_playtime)
