Question
Hello there! I’m working on a checkpoint system, which works via packing the current scene, and loading it up whenever the player dies. However, the variables of all the objects inside the loaded scene are not saved. For example, dead enemies come back to life and broken doors are un-broken. How would I go along with saving the variables of these separate scenes? Below is my saving and loading script, as well as the scene tree.
func _process(delta):
if Input.is_action_just_pressed("1"):
var node_to_save = self
var scene = PackedScene.new()
scene.pack(node_to_save)
ResourceSaver.save(scene, "res://levelCheckpoint.tscn")
if Input.is_action_just_pressed("2"):
if !FileAccess.file_exists("res://levelCheckpoint.tscn"):
get_tree().reload_current_scene()
else:
var new_scene = ResourceLoader.load("res://levelCheckpoint.tscn").instantiate()
get_tree().current_scene.queue_free()
get_tree().root.add_child(new_scene)
get_tree().current_scene = new_scene
An example enemy script as well:
extends CharacterBody3D
var player = null
var health = 3
var knockback_velocity: Vector3
var yesdead = false
@export var player_path : NodePath
const SPEED = 13.0
@onready var anim = $AnimatedSprite3D
@onready var shield = $CSGSphere3D
@onready var nav_agent = $NavigationAgent3D
signal dead
# Called when the node enters the scene tree for the first time.
func _ready():
player = get_node(player_path)
anim.play("default")
shield.visible = false
set_process(false)
$Bulletbox/CollisionShape3D.set_deferred("disabled", true)
# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(_delta):
velocity = Vector3.ZERO
nav_agent.set_target_position(player.global_transform.origin)
var next_nav_point = nav_agent.get_next_path_position()
velocity = (next_nav_point - global_transform.origin).normalized() * SPEED
look_at(Vector3(player.global_position.x, global_position.y, player.global_position.z), Vector3.UP)
if knockback_velocity:
velocity = knockback_velocity
move_and_slide()
func _on_bulletbox_body_hit(dam):
health -= dam
if health <= 0 and yesdead == false:
yesdead = true
$Bulletbox/CollisionShape3D.set_deferred("disabled", true)
$CollisionShape3D.set_deferred("disabled", true)
dead.emit()
set_process(false)
$Walk.stop()
$AnimationPlayer.play("Death")
$Hitbox/CollisionShape3D.set_deferred("disabled", true)
using res:// paths won’t work once you export the game, res:// becomes read-only so no data may be saved. You could try user://.
Your variables may need to be @exports for them to save as part of a packed scene.
thanks a ton! this worked, yes.
