    commands.spawn((
        SpriteBundle {
            transform: Transform::from_xyz(window.width() / 2.0, window.height() / 2.0, 0.0),
            texture: asset_server.load("assets/sprites/ball_blue_large.png"),
            ..default()
        },
        Player {},
    ));
}

fn spawn_camera(mut commands: Commands, window_query: Query<&Window, With<PrimaryWindow>>) {
    let window: &Window = window_query.get_single().unwrap();

    commands.spawn(
        Camera2dBundle {
            transform: Transform::from_xyz(window.width() / 2.0, window.height() / 2.0, 1.0),
            ..default()
    });
}

I followed allong a tutorial and according to the tutorial, this should display a blue ball in the middle of the window. Id doesn't though.
What could have been my issue?

@versed hare I think your image didn't load correctly, and the reason for that is that you don't need to/shouldn't put the "assets" folder in the path: asset_server.load("sprites/ball_blue_large.png")

I think, its optional, if you put it there.
After removing it, it still doesn't show the texture

#

I don't think it's optional, if you put it it will search in [root of your project]/assets/assets/sprites/ball_blue_large.png
How do you launch your game?

#

Shift + F10 in RustRover

#

worked for the command line stuff

lilac yarrow Sep 19, 2023, 10:34 AM

#

Can you try a cargo run in a terminal at the root of your project just to check?

hmmm

Is your file really there, does it have another name?

versed hare Sep 19, 2023, 10:36 AM

#

it is there

lilac yarrow Sep 19, 2023, 10:37 AM

#

What you can try to do also to check if it's really an image loading problem and not a camera setting problem, is to put a color to your sprite:

SpriteBundle {
            transform: Transform::from_xyz(window.width() / 2.0, window.height() / 2.0, 0.0),
            //texture: asset_server.load("assets/sprites/ball_blue_large.png"),
            sprite: Sprite {
              color: Color::BLUE,
              custom_size: Some(Vec2::new(50.,50.)),
              ..default()
            }
            ..default()
        },

#

But it does look like an image loading problem judging by the error above yeah

lilac yarrow What you can try to do also to check if it's really an image loading problem and...

yeah, must be a loading issue

#

its a path issue

#

It works using the absolute path

lilac yarrow Sep 19, 2023, 10:41 AM

#

Normally if you run cargo run from bevy-ball-game and the file is in ./assets/sprites/ball_blue_large.png it should work
Do you have an environment variable like CARGO_MANIFEST set?

#

The error message tells you where it's looking so if your image is really there it's weird

#

You're on version 0.11.2 right?

versed hare Sep 19, 2023, 10:42 AM

#

aaah

#

/home/over/Documents/Coding/Rust/bevy-ball-game/src/assets/sprites
thats the path
I put assets in src

lilac yarrow Sep 19, 2023, 10:42 AM

#

You should put it in the same directory as src not under src

versed hare Sep 19, 2023, 10:43 AM

#

now it works, thank you for helping me debug this
