GDextension C++ scene add a autoload has effect with other scripts.

Tested versions

Since 4.1 to current 4.2.1

System information

Godot v4.2.1.stable - openSUSE Tumbleweed 20231208 - Wayland - Vulkan (Forward+) - dedicated AMD Radeon RX 6600 (RADV NAVI23) () - AMD Ryzen 7 5700G with Radeon Graphics (16 Threads)

Issue description

Note: Every node I made it in GDextension C++ After adding a scene to autoloads, some other scenes/nodes have a weird behavior. In this case, I have a scene: Level01 made in GDextension and has the node Music (audioStream...) and set it to autoplay true. Even if I set this, Keeps playing: if (Engine::get_singleton()->is_editor_hint()) set_process_mode(Node::ProcessMode::PROCESS_MODE_DISABLED); Or my Player (also made in GDextension), the camera does not follow the player. `

• Player (CharacterBody2d or 3d)
• • ...
• • ... Pivot (Node2d or 3d)
• • • SpringArm // If is 3D
• • • • Camera `

Also I have a scene transition (also made in GDextensions) if I disable it in the Autoloads options, still visible.

Steps to reproduce

If I create a node with GDextension C++, then add it to a scene, save it, like:

// StoreConfigs.h
...
// StoreConfigs.cpp
if (Engine::get_singleton()->is_editor_hint()) // Tried in the Constructor or _read function, still the same
    set_process_mode(Node::ProcessMode::PROCESS_MODE_DISABLED);
...
// Compile, I use CMake to compile, my Flags:
-fno-gnu-unique -fno-exceptions -fPIC -g -Wwrite-strings -m64 -march=x86-64 
-O2 -fvisibility=hidden -m64 -fvisibility=hidden  
-fPIC -DHOT_RELOAD_ENABLED -DLINUX_ENABLED -DUNIX_ENABLED -DDEBUG_ENABLED -DDEBUG_METHODS_ENABLED -DNDEBUG -fcoroutines -pthread

// Then in Godot, Create a new Scene > Other Node > StoreConfigs > Save the Scene
// Then Project > Project Settings > Autoload and Add the StoreConfigs Scene.

Minimal reproduction project (MRP)

Could be posible with a started project, just add a scene with the steps that I listed and happens.

Not sure I understood this correctly, but if you want to stop the audio, you should just call the AudioStreamPlayer's stop() method. I think calling set_process_mode() on the AudioStreamPlayer or one of its ancestors does nothing, because it just handles starting and stopping the audio and doesn't do much "processing" in Godot's "do something once per frame" sense.

In the Level Cpp script the music (audioStreamer...) the autoplay is on, but I set:

// Level00
if (Engine::get_singleton()->is_editor_hint()) // Tried in the Constructor or _read function, still the same
    set_process_mode(Node::ProcessMode::PROCESS_MODE_DISABLED);

So, even if I dont start the game: F5 or Run Project the music starts.

• If I dont set the StoreConfig (made in Cpp) in Autoload, everything works fine.
• If I set the StoreConfig (made in Cpp) in Autoload, some scripts like Level00, does not work this:

  if (Engine::get_singleton()->is_editor_hint()) // Tried in the Constructor or _read function, still the same
  set_process_mode(Node::ProcessMode::PROCESS_MODE_DISABLED);

  

Also, I have made a script that made transitions made in Cpp, if in the Autoload options, if I disable it, still working:

So you're saying that the AudioStreamPlayer is part of your level and has Autoplay enabled and you want it to start playing when the scene loads and

• if StoreConfigs.tscn is not set up as an Autoload, then the music plays when the game is started,
• if StoreConfigs.tscn is set up as an Autoload, then the music does not play when the game is started?

If that's the case, then something in StoreConfigs.tscn might interfere with the audio player.

Also, since your screenshot is cut off just above the Autoplay property, please note that Playing and Autoplay are two different things. Playing is just the current (preview) state. Setting that in the Editor won't affect what happens when you run the game.

Mmm ... the thing is: Right now in the Level00 cpp I set to music autoplay to true. also I have this in the Level00 cpp

// Level00.cpp
if (Engine::get_singleton()->is_editor_hint()) // Tried in the Constructor or _read function, still the same
    set_process_mode(Node::ProcessMode::PROCESS_MODE_DISABLED);

While Not running the game: pressing F5 or Run Project.

• If I dont set the StoreConfig (made in Cpp) in Autoload, everything works fine. The Music Not played as supposed to be while is not playing the game.
• If I set the StoreConfig (made in Cpp) in Autoload:
  • The music auto start, even if is not playing the game: F5 or Run Project. In other words. Dont care the set_process_mode(Node::ProcessMode::PROCESS_MODE_DISABLED);
  • And some other issues, like the transition Scenes.
