In my game I wan the enemies to spawn at a random position in a circle around the player. How can I achieve that?
My attempt was to add a “Spawn”-Child to the player with following script (not working):
func _ready():
while true:
var forward_dir :int= randi_range(0, 360)
var amount:int = randi_range(12, 16)
var enemy = preload("res://enemy.tscn").instantiate()
get_node("/root/WorldScene").add_child.call_deferred(enemy)
await enemy.ready
enemy.look_at_from_position(global_position, Vector3(forward_dir,1,forward_dir))
enemy.global_position.x += amount
enemy.global_position.z += amount
await get_tree().create_timer(1).timeout
→ not working, but I have to say I didn’t do much in 3D yet especially with something like this

You could create a random position in your world and normalize this vector (.normalized() gives it length of 1). This value you could multiply it with a random number from the inner spawn radius to the outer. Finally you give the enemy this random position + the player position.
func _ready():
var player_position :Vector3 = $Player.global_position
#just to get a random point in the world
var enemy_position :Vector3 = Vector2(randf_range(-10, 10), 0, randf_range(-10, 10))
#random number; defines how far from the player your enemy will spawn
var enemy_distance = randf_range(MIN_RANGE, MAX_RANGE)
enemy_position = enemy_position.normalized()
#muliplies the random vector from the start with your radius
enemy_position.x *= enemy_distance
enemy_position.z *= enemy_distance
var enemy = load("res://enemy.tscn").instantiate()
$WorldScene.add_child(enemy
#spawns the player at a position related to the player
enemy.global_position = player_position + enemy_position
I hope my code will work for you, because I only tested it in 2D (but 3D is the same). I think there are more efficient ways to do what you want, but this is what I would do.
