I want after my players death my enemy and bullet fade out and then been deleted.
You can either use an animation-player or a tween to change the alpha value of the modulate-property to 0 and when its finished you can call queue_free()

i was making it with tween but it not working
print("you are dead")
var pop_effect_instance = PopEffect.instance()
pop_effect_instance.position = position
pop_effect_instance.emitting = true
get_parent().playerDied(pop_effect_instance)
$"/root/Game/Timer1".stop_timer()
var parent_node = get_parent()
for child in parent_node.get_children():
if child.is_in_group("Bullet") or child.is_in_group("Enemy"):
fade_out_and_delete(child)
queue_free()
func fade_out_and_delete(node):
var tween = Tween.new()
node.add_child(tween)
tween.interpolate_property(node, "modulate:a", node.modulate.a, 0, 1, Tween.TRANS_LINEAR, Tween.EASE_IN_OUT)
tween.start()
tween.connect("tween_completed", self, "_on_fade_out_complete", [node])
func _on_fade_out_complete(tween, node):
if node is Node:
node.queue_free()
tween.queue_free()
i think i cant use this tween as i am beginner but with animation i dont understand how to make it fade out
@herrspaten i made it, but in the script there is an error
extends AnimationPlayer
func play_fade_out():
play("fadeout")
whats the error?
Put line 62 in your Game.gd script in the playerDied-method. “$” only accesses child-nodes. The animationPlayer is a child of the Game-Scene and not of the Player-Scene

Put it before the “yield(get_tree()…)”. Yield stops the method until the given signal is recieved. In this case it waits till the 3 second timer finished

The problem with the bullets is, that you dynamically spawn bullets and you cant reference them in the animationplayer. In this case you should probably use signals
I was thinking about that i spawn them and thats the problem but i think i dont now how to use signals properly, so thank you very much with this.
First add this method to the script of every object you want to fade out:
func fade_out() -> void:
var tween = Tween.new()
add_child(tween)
tween.interpolate_property(self, "modulate", Color(1, 1, 1, 1), Color(1, 1, 1, 0), 1)
Then add this in the corresponding spawn method in the Game.gd script:
signal fade_out
func spawnObject() -> void:
var object = PACKED_OBJECT.instantiate()
connect("fade_out", object, "fade_out")
add_child(object)
This is just a sample spawn-method. Important is that you have the line:
connect("fade_out", object ,"fade_out")
and then you can emit the signal in your playerDied-method:
func playerDied(pop_effect_instance) -> void:
add_child(pop_effect_instance)
emit_signal("fade_out")
yield(get_tree().create_timer(3), "timeout")
get_tree().change_scene("path/to/new/scene")

Thank you very much i will try soon.
This was just example code. Use your spawn_bullet-method and put this line in it:
connect("fade_out", bullet_instance, "fade_out")
ah 
okay i will try
Put a print(“Fading out”) in the fade_out()-method of the bullet and test if it gets printed
