(ANSWERED) How can I delete all instances in certain group?

Question

I want that in certain moment all enemies (Which are in a group) get deleted.
I could create a global variable and detect it from the enemy script.
So when it changes it deletes the enemy.

But is there any easier way to delete all objects in a group (All objects are instances of a scene using the preload method) ?

Answer 1

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

Thanks for answering :)

Answer 2

call_group may help

get_tree().call_group(SceneTree.GROUP_CALL_DEFAULT,"enemy","queue_free")

Or use the enemies delete/kill method if you need to do something else instead of free directly.
