.add_systems DONT WORK

Bevy version

current main version - 0.15

What you did

I wanted to try out a new engine (Bevy) and started following the "Get Started" documentation. Things went off track when I tried to use app.add_systems It seemed like such a basic and straightforward function that should definitely work, so I feel like I must be missing something. But for some reason, it just doesn't work—the simplest example code doesn't run for me. Everything else I've tested so far works perfectly fine for me. Fot example connecting plugins. When installing rust and bevy, I strictly followed the provided instructions. Also example was working for me.

use bevy::prelude::*;

fn main() {
    let mut app = App::new();
    app.add_systems(Startup, hello_world);
    app.run();
}

fn hello_world() {
    println!("hello world");
}

Windows 11.

What went wrong

Additional information

Interesting. Curious to know if adding the DefaultPlugins to app makes it work.

[PhantomMorrigan]

yeah you need DeafultPlugins or MinimalPlugins, otherwise you App won't have a runner, and thus can't run iirc.

I was wrong sorry.

[viridia]

If that's the case, then the example in the documentation is wrong.

[PhantomMorrigan]

Actually I retract what I said earlier, this should work. Also, It does actually work, at least on Linux.

Try checking if there is some antivirus software breaking things? I've at least seen that happen before.

i dont have any)

I have completely removed the antivirus from my Windows system and I don’t use any third-party ones. Also, I can run the example project and add the default plugin. All it works. I used a clean installation and tried running cargo clean, but none of that helped me.

i use 23H2 Windows ver. OS 22631, 4602 build

Just a note that I can't repro the crash with the example code on Mac.
