Hi,
Add all the aliens to a group. When the player dies, send a signal to the group. When the alien gets the signal, make it die.

So something like:

in the alien script _ready() function:

add_to_group("alien")

Add a function for the alien to react to the death of the player:

func player_dead() -> void:
      # make the alien gloat ;)
      queue_free()

Then in your player script, when the player dies:

get_tree().call_group("alien", "player_dead")

Thank you so much… dude :slight_smile:

Add aliens in group enemy and when the player dies run this code

var enemies = get_tree().get_nodes_in_group("enemy")
for i in enemies:
	i.queue_free()

Thank you So much I Will try it
