This happend to me right noww as I tried to write a gui task manager for the GNU/Linux OS

ofc I imediatly upgraded it from winxp to gnu/linux

I hope memes are okay here

So I thought about this in the shower amd it makes sense to me, like praying and stuff never worked for most people I know, so a direkt link to god gotta be unlikely. That made me conclude that religion is probably fake, no matter if there's a god or not. Also people speaking to the same god being given a different set of rules sounds stupid, so at least most religions must be fake.

Why do some cars have their engines in the front and some in the back, what are the advantages and disadvantages of the two builds. And why doesn't every car have full wheel drive?

So I want to update the sprite so my character looks in a different direction each time the player presses left/right, how could I do this? I can't do it in the setup fn, since it's a startup system, appreciate any help

EDIT: changed formating

here is my code:

use bevy::prelude::*;

`fn main() {
    App::new()
        .add_plugins(DefaultPlugins.set(ImagePlugin::default_nearest())) // prevents blurry sprites
        .add_systems(Startup, setup)
        .add_systems(Update, animate_sprite)
        .add_systems(Update, player_movement_system)
        .run();
}

const BOUNDS: Vec2 = Vec2::new(1200.0, 640.0);
static mut FLIP_BOOLEAN: bool = false;

fn set_flip_boolean(boolean: bool) {
    unsafe {
        FLIP_BOOLEAN = boolean;
    }
}

fn get_flip_boolean() -> bool{
    unsafe {
        FLIP_BOOLEAN
    }
}

#[derive(Component)]
struct Player {
    movement_speed: f32,
}

#[derive(Component)]
struct AnimationIndices {
    first: usize,
    last: usize,
}

#[derive(Component, Deref, DerefMut)]
struct AnimationTimer(Timer);

fn animate_sprite(
    time: Res<Time>,
    mut query: Query<(&AnimationIndices, &mut AnimationTimer, &mut TextureAtlas)>,
) {
    for (indices, mut timer, mut atlas) in &mut query {
        timer.tick(time.delta());
        if timer.just_finished() {
            atlas.index = if atlas.index == indices.last {
                indices.first
            } else {
                atlas.index + 1
            };
        }
    }
}


fn setup(
    mut commands: Commands,
    asset_server: Res<AssetServer>,
    mut texture_atlas_layouts: ResMut<Assets<TextureAtlasLayout>>,
) {
    let texture = asset_server.load("sprites/Idle01.png");
    let layout = TextureAtlasLayout::from_grid(Vec2::new(64.0, 40.0), 5, 1, None, None);
    let texture_atlas_layout = texture_atlas_layouts.add(layout);

                index: animation_indices.first,
            },
            
            ..default()
        },
        Player {
            movement_speed: 500.0,
        },
        animation_indices,
        AnimationTimer(Timer::from_seconds(0.1, TimerMode::Repeating)),
    ));
}

    time: Res<Time>,

    mut query: Query<(&Player, &mut Transform)>,

    let (guy, mut transform) = query.single_mut();

    let mut movement_factor = 0.0;

    let mut movement_direction = Vec3::X;

    if keyboard_input.pressed(KeyCode::ArrowLeft) {
        movement_factor -= 1.0;
        movement_direction = Vec3::X;
        set_flip_boolean(true);
    }

    if keyboard_input.pressed(KeyCode::ArrowRight) {
        movement_factor += 1.0;
        movement_direction = Vec3::X;
        set_flip_boolean(false);
    }

    if keyboard_input.pressed(KeyCode::ArrowUp) {
        movement_factor += 1.0;
        movement_direction = Vec3::Y;
    }

    if keyboard_input.pressed(KeyCode::ArrowDown) {
        movement_factor -= 1.0;
        movement_direction = Vec3::Y;
    }


    let movement_distance = movement_factor * guy.movement_speed * time.delta_seconds();
    let translation_delta = movement_direction * movement_distance;
    transform.translation += translation_delta;

    let extents = Vec3::from((BOUNDS / 2.0, 0.0));
    transform.translation = transform.translation.min(extents).max(-extents);
}

tbh I did a horrible paint job, but she still liked it

EDIT: the parts are 3d printed (not my model tho)
