Hi there. My question would be that I want more maps in this code, but that they come in line at the start of each game. So when I start the game it is map1 and on the next reload map2 next reload map3…etc
here is my code.Hope you understand. Sorry for my english ,google translate

export (PackedScene) var map_scene = preload("res://maps/Map1.tscn")
onready var map: Node2D = $Map

func _do_game_setup(players: Dictionary) -> void:
func reload_map() -> void:
var map_index = map.get_index()

map = map_scene.instance() = 'Map'
move_child(map, map_index)
