Hard workers, I was thinking about spawning lamps around the player, but it seems like it’s going to be quite liquid.
I’m making a script in the main node of the level with the following variables:
var num_lamps = 10
var radius = 50
var lamp_scene = preload("res://Resources/Scenes/Level1Component/LightLamp.tscn")
var lamps = []
Next, in the process function, I check the distance between the player and each lamp
And I check whether I need to create a new one
func _process(delta):
for lamp in lamps:
if lamp.global_position.distance_to(Global.player.global_position) > radius:
lamp.queue_free()
lamps.erase(lamps.find(lamp))
if lamps.size() < num_lamps:
spawn_lamps()
the spawn_lamps() function calculates a random position around the player (here I most likely did nonsense)
Creates a lamp instance, positions it and adds it to the level
func spawn_lamps():
var direction = Vector3(randi_range(-1, 1) , 1.854 , randi_range(-1, 1))
var position = Global.player.global_position + direction * radius
var lamp = lamp_scene.instantiate()
if lamp != null:
lamp.global_position = position
add_child(lamp)
lamps.append(lamp)
I received an error:
Invalid get index 'global_position' (on base: 'previously freed').
How to fix this error? And did I write the formula for calculating the position of the lamp correctly?
It seems like I made some changes, but the lamps are not created, I’m obviously making very strange code
func _process(delta):
var remaining_lamps = []
for lamp in lamps:
if lamp and not lamp.is_queued_for_deletion():
if lamp.global_position.distance_to(Global.player.global_position) > radius:
lamp.queue_free()
else :
remaining_lamps.append(lamp)
lamps = remaining_lamps
if lamps.size() < num_lamps:
spawn_lamps()

Hello o/
I feel like I might be missing part of the puzzle here. What is “lamp” in this context? It’s defined in your first message but not in the last. Try printing it out to console and see what comes up.
func _process(delta):
var remaining_lamps = []
for lamp in lamps:
if lamp and not lamp.is_queued_for_deletion():
if Global.lamp.global_position.distance_to(Global.player.global_position) > radius:
lamp.queue_free()
else :
remaining_lamps.append(lamp)
lamps = remaining_lamps
if lamps.size() < num_lamps:
spawn_lamps()
func spawn_lamps():
var direction = Vector3(randi_range(-1, 1) , randi_range(-1, 1) , randi_range(-1, 1))
var position = Global.player.global_position + direction * radius
var lamp = lamp_scene.instantiate()
Global.lamp.global_position = position
add_child(lamp)
print(lamp)
lamps.append(lamp)
I am completely correct that the program logic itself is bad.
I’m trying to make the lamps spawn at the same height, in different places, around the player within a radius of 50 meters and when leaving this radius they are removed.
you need to add a global position to the lamp position, something like this:
#example
lamp.position = global_position
and it might be a good idea to change the var position variable and call it something else, you might have a conflict with self.position depending on the context
otherwise, you need to add a global position of something to the lamp position… so if you want a global position for a lamp, you have to assign it to the lamp position
