Looks like a problem on your end. I don't use Linux, and the only thing I can do is google for solutions ((snd_pcm_dmix_open) unable to open slave):

[mrDIMAS]

Looks like stable from crates.io. I think I can submit a patch 0.33.2. I will do this only tomorrow.

[mrDIMAS]

Looks like your OS does not support OpenGL 3.3. Run glxinfo to check which version is supported. If you're trying to run the editor under an virtual machine, make sure you use VMWare Workstation. Other virtual machines does not support OpenGL 3.3+.

[realroot2185]

It is not in a VM.

Do I have 4.60 version and 3.20 for ES?

It also might be related to ALSA, in any case the error message in not helping at all. You can help the project by debugging the issue.

[realroot2185]

How do I debug?
Using RUST_BACKTRACE=full?

[mrDIMAS]

I think you need to go to https://github.com/FyroxEngine/Fyrox/blob/master/src/engine/mod.rs#L1304 and replace ? signs with unwrap() to see what's exactly fails.

[realroot2185]

I cloned the repo and replaced ? signs.
After I ran cargo build.

Then do I simply use cargo run --package editor --release again?

[mrDIMAS]

You can just cargo run --package fyroxed from the engine repo to run the editor without any plugins.

[realroot2185]

cargo run --package fyroxed

Audio is working fine so I did not think about that error.

I made the file /etc/modprobe.d/alsa.conf with this content:
options snd_hda_intel index=1
And now it works.

Maybe fyrox could give the error as after I modified the function?
That's why I did not close the issue.

Looks like an outdated built-in scene, go to your_project/editor/src/main.rs and find scene field in StartupOptions and set it to None. This way the editor should start without the scene and it will load fine.

[realroot2185]

<project>/editor/src/main.rs

//! Editor with your game connected to it as a plugin.

use fyrox::event_loop::EventLoop;
use fyroxed_base::{Editor, StartupData};
use rpg::GameConstructor;

fn main() {
    let event_loop = EventLoop::new().unwrap();
    let mut editor = Editor::new(
        &event_loop,
        Some(StartupData {
            working_directory: Default::default(),
            scenes: vec!["data/scene.rgs".into()],
        }),
    );
    editor.add_game_plugin(GameConstructor);
    editor.run(event_loop)
}

This is what I have, it's the default code generated by the template.

I set it to scenes: Vec::new() and now it starts.

Looks like an outdated built-in scene, go to your_project/editor/src/main.rs and find scene field in StartupOptions and set it to None. This way the editor should start without the scene and it will load fine.

Will that scene be fixed?
Are there other scene that I can use?

[mrDIMAS]

I'll fix this. Which version of the engine do you use btw?

[realroot2185]

Not sure to how check.
In my path, which has ~/.cargo/bin, I have only fyrox-template.

cargo install --list 
fyrox-template v0.10.0:
    fyrox-template

I have fyrox-0.33.1 in ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/.

[realroot2185]

Could you tag me when you do it?
Thanks.

[mrDIMAS]

I just checked this bug and I cannot reproduce it. Built-in scene loads fine, in the stack trace I see that it fails on make_quad_tree, but I just created a terrain, saved the scene, restarted the editor and it loads fine. I did this on 0.33.1. Any details of how to reproduce the bug?

[realroot2185]

I have that problem with RPG scene: https://fyrox-book.github.io/tutorials/rpg/tutorial-1/data.zip.
Did you try the built-in scene of the template or that too?

[mrDIMAS]

That scene needs to be re-made anyways, I don't have time for this now. Just create your own scene

[realroot2185]

Is there some other scene that one can take from some Fyrox game for example?

[mrDIMAS]

You can take Sponza from here - https://github.com/FyroxEngine/Fyrox-demo-projects/tree/main/sound/data
