  • I want to make efficient RPG teleport

Hello! I'm beginner on Godot. I'm working in a prototype project to I learn while try to work on my final project. I don't know how to make my Player teleport. I'm creating a "Resident Evil like" game to make the character travel from the scenes, but TOTALLY 2D.

Ok, I've tried to teleport my Player with two manners:

ONE. Putting my Player.tscn on the map scene and using Teleport.tscn as instanced node. Result: ERROR Screenshot: * Teleport.gd:

extends Area2D

export (String) var mapa
export (Vector2) var coordenadas
export (String) var posicao

func _on_Teleport_body_entered(body):
	get_tree().change_scene(mapa + ".tscn")
	if coordenadas != null:
		# !!!!! TELEPORT NOT WORKING >:( !!!!!
		print($Player)
		#$Player.position.x = coordenadas.x
		#$Player.position.y = coordenadas.y

TWO. Creating Map.tscn to put my Player on a kind of glass and call the_map's scene_ with "add_child". Result: Screenshot: * Map.gd:

extends Node2D

const MAP = "res://Cozinha A.tscn"
const POSITION = Vector2(100, 50)

func _ready():
	teleport(MAP, POSITION, "up")

func teleport(tp_name, tp_position, tp_turn):
	var map_name = preload(tp_name)
	var map_position = POSITION
	var map = map_name.instance()
	var current_map = map_name
	add_child(map)
	$Player.set_position(POSITION)

Option 1 won't work because once you use change_scene, the original scene is freed (no longer there).

For option 2, Godot told you what the problem is. The preload wants a string and you gave it a MAP parameter. Alternately, since the MAP variable points to a string, maybe the problem is that it's a const? Try changing it to var...?

Option 1: Makes sense, but in the next map have an Player.tscn. How can I link the Player.tscn node with my freed Teleport.tscn node?

Option 2: This error is ocurring because the Godot want a constant to I use on preload. On my code, I need to use a custom variable to make my funcion teleport works :(

Thanks a lot for your reply, anyway!! o

For option two, you can replace preload with load and it should work. You cannot preload a variable due to the fact that it may change (even if the variable is marked constant, as there was a bug where constant variables were changing).

WOAH! WORKS FINE HERE!! VERY VERY THANK YOU @TwistedTwigleg !! <3 I don't decided whose options is more efficient for my kind of project, but the option two looks works very well for now.
