Loading scenes several times

Berfandil

Hey all! I have a menu scene, an intro scene and a level 1 scene currently. I switch the scenes the followig way:     1. var my_next_scene = ResourceLoader.load(path)     2. var scene_root =  get_tree().get_root().get_child(get_tree().get_root().get_child_count()-1)     3. scene_root.queu_free()     4. scene_root = my_next_scene.instance()     5. get_tree().get_root().add_child(scene_root) This works just fine, until I want to load the same scene the second time. When I try that, the whole screen becomes black and nothing happens. Any ideas what is causing my problem?

your 2nd line is very confusing.you should define your scene root as a global variable. or just use get_tree().get_root() as your root

Where are you calling the script from? Are there other children of the root? It sounds like you might be freeing the wrong scene. And by the way you can just use get_tree().change_scene(). http://docs.godotengine.org/en/latest/tutorials/step_by_step/scene_tree.html#changing-current-scene

</blockquote> I used that 2nd line, because I had a 6th line, in which I called a function of an object that was in the newly added scene. Changing the scene is working - I wrote a 'print("I am alive!")' line in the _ready() function to see when the scenes start. It is rather the case, that the scene starts, but is then black. I write a 'print(delta)' line in the _process(delta) function, but it doesn't  write anything... EDIT: Here is a video of the problem: https://www.youtube.com/watch?v=AyXS4jQYlpg&feature=youtu.be The 2 errors are describing that I am using too much bones to be indexed - in the level_1 scene.

So the menu scene seems to work properly, it's the intro scene that goes black the second time around? The intro scene's ready function fires but nothing else works? That narrows it down a bit. Are you passing any sort of data to the intro scene before it starts? Or is there any other way that it would be different one time from another?

I change to the intro scene both times with the same call, which is: <div>func start_level(num): </div><div>     Input.set_mouse_mode(2) </div><div>     Globals.set("level_to_start_after_intro",num) </div><div>     get_tree().change_scene("res://intro_videos/intro"+str(num)+"video.scn") This is how my intro_scene is set up: <img src="http://i.imgur.com/Byqdz4W.png" alt=""> And this is the script attached to video_root: extends Control var my_VideoPlayer = null var my_loading_screen = null var my_black_background = null var my_label = null func _ready():      print("intro STARTED")      #      my_VideoPlayer = get_child(0)      var my_window_size = get_viewport().get_rect().size      my_VideoPlayer.set_size(my_window_size)      my_VideoPlayer.play()      #      my_loading_screen = get_node("loading")      my_loading_screen.set_hidden(true)      my_black_background = my_loading_screen.get_node("black")      my_black_background.set_scale(my_window_size*2.0)      my_label = my_loading_screen.get_node("Label")      my_label.set_pos( (my_window_size-my_label.get_size()) / 2.0 )      #      set_process(true) func process(delta):      if (not my_VideoPlayer.is_playing()):           my_loading_screen.set_hidden(false)           set_fixed_process(true) func fixed_process(delta):      get_tree().change_scene("res://level_"+str(Globals.get("level_to_start_after_intro"))+".scn") </div>

Sorry, my bad, got it figured out. It was caused by the pausing. I set 'get_tree.set_pause(true)' during the level, when I brought up the menu, but didn't set 'get_tree.set_pause(false)' after it anywhere. Thanks for all the help guys, much appreciated. :)
