Positioning doesn't work properly

Question

I have this boss enemy that shoots 5 bullets when this function is triggered. The bullets gets spawned but the positioning of then is always wrong, I want it to spawn bullet in 5 spawn positions which are children of the boss but it spawns them at origin. I tried changing the line that ends with "*********" a lot and tried every combination of "position" and "global_position".

I use the same logic for player bullets(only diffrence there that player shoots 1 at a time) and it works fine but I really have no idea why it doesn't work for boss enemy.

 for i in $Shoot.get_children():
    var bullet_ins = bullet.instance()

    bullet_ins.global_position = i.global_position***
    bullet_ins.rotation = i.rotation

    bullet_ins.active = true

    get_parent().get_parent().add_child(bullet_ins)

    bullet_ins.update_stat(5, 20000, 3)
    print("shoot")

Answer 1

set position after adding it as a child
