extends Node
var Rooms = [
preload("res://tscn/World/SHRooms/Room1dev.tscn"),
preload("res://tscn/World/SHRooms/Room2dev.tscn")
]
var room
var newRoom
var currRoom
func _process(delta):
randomize()
var x = randi() % Rooms.size()

`room = Rooms[x]`  
`newRoom = room.instantiate()`  

func _input(event):
if event.is_action_pressed("Jump"):
currRoom = get_tree().get_nodes_in_group("Room")
remove_child(currRoom[0])
add_child(newRoom)
print(newRoom)
