Portals

There's a documentation page for portals and rooms [1] but it's outdated (made for Godot 3.5, I'm using 4.3).

Portals to different rooms This needs a lot of reorganizing of the code for it to work... Currently stuck at trying to delete one room once there has been a switch from another (queue_free function not working).

The script is supposed to instantiate a new scene once the body ("Player") enters the portal. After the player has entered the new scene, the previous one is supposed to be deleted with the queue_free function.

Currently I have:

• A portal (Area3D) with the script:

extends Area3D
var next_scene = preload("res://rooms/room_2.tscn")
var current_scene = preload("res://rooms/room_1.tscn")
func _on_body_entered(body: Node3D) -> void:
   if body.name == "Player":
       if body.in_transition == false:
           body.in_transition = true
           print("something might work")
           var instanced_scene = next_scene.instantiate()
           get_tree().root.get_node("World").add_child(instanced_scene)
func _on_body_exited(body: Node3D) -> void:
   if body.in_transition:
       body.in_transition = false 

The script with all the code that was tried, didn't work and commented out

• room2 (Node3D) with the script:

extends Node3D 
@onready var player = $Player
@onready var room1 = "res://rooms/room_1.tscn"
# Called when the node enters the scene tree for the first time.
func _ready() -> void:
       player.camera.make_current()

The code ONLY for the room that needs to be instantiated. It creates the room, the player and the camera the player is looking through and swtiched to the new camera of the player

• the World (root) node (Node3D):

extends Node3D
@onready var room1 = "res://rooms/room_1.tscn"
var room1_scene = preload("res://rooms/room_1.tscn")
# Called when the node enters the scene tree for the first time.
func _ready() -> void:
   if room1_scene != null and is_instance_valid(room1):
       #room1.queue_free()
       var deletion_scene = room1_scene.instantiate()
       deletion_scene.queue_free()
       print("room1 deleted")

No error appears with this version of the code but it doesn't work.

The script for the world node from which I am trying to delete the scene the player left

Question:

• How to adjust the code to delete the previous room? (While allowing the user to enter back)

FIXED WITH adding:

get_tree().root.get_node("World/room1").free()

This fixes it because what I was doing before, calling a variable in the queue_free() function, wasn't working and was giving it a null value
Next steps:

• Why is the portal in the new scene not appearing?

error code: W 0:00:25:0044   portal.gd:17 @ _on_body_entered(): Node './Portal' was modified from inside an instance, but it has 
vanished.
 <C++ Source>   scene/resources/packed_scene.cpp:254 @ instantiate()
 <Stack Trace>  portal.gd:17 @ _on_body_entered()

The instantiated scene does not appear in the HTML exported version. There are the errors that pop up:

errors that appear when I uploaded the most recent version of the godot project to html

• How to do this code in the World script instead of the Portal script?

question for thijs, but only if you have time!

• Can portals refer to/lead to HTML pages? (I would love to link some rooms to bitsy pages if possible)

question for thijs

HTML/itch.io Exporting

Questions:

• If the game is uploaded as an html page, is it better to have the menu as javascript button on top of the game (canvas item) or to have an in-game menu? Would the in-game menu access the in-game mechanism better? (Such as room change)
  

question for thijs

• Creating subdomains for your website?
• How to improve loading?

Texture

Fixed:

• All texture issues can be solved with importing glft/glb instead of a blend file
• light from blender need to be 50mW or less
