Question
i tried to follow a tutorial called cute and simple dialog box but something does not work. I am having a lot of issues because the variable label on the dialog manager script results null, and because of that some functions do not work. here’s the script:
extends Node2D
@onready var player = get_tree().get_first_node_in_group("player")
@onready var label: Label = $Label
const base_text = "[E] to"
var active_areas = []
var can_interact = true
func register_area(area: InteractionArea):
active_areas.push_back(area)
func unregister_area(area: InteractionArea):
var index = active_areas.find(area)
if index != -1:
active_areas.remove_at(index)
func _process(delta):
if active_areas.size() > 0 && can_interact:
active_areas.sort_custom(_sort_by_distance_to_player)
label.text = base_text + active_areas[0].action_name
label.global_position = active_areas[0].global_position
label.global_position.y -= 36
label.global_position.x -= label.size.x / 2
label.show()
else:
label.hide()
func _sort_by_distance_to_player(area1, area2):
var area1_to_player = player.global_position.distance_to(area1.global_position)
var area2_to_player = player.global_position.distance_to(area2.global_position)
return area1_to_player < area2_to_player
func _input(event):
if event.is_action_pressed("interact") && can_interact:
if active_areas.size() > 0:
can_interact = false
label.hide()
await active_areas[0].interact.call()
can_interact = true
