bevy_pixel_buffer

A library to draw pixels in bevy.

• Easy to set up and use.
• Can be integrated into an existing project.
• Allows dynamic resize of the pixel buffer to fill an area such as the window.
• Support for multiple pixel buffers.
• Allows to easily attach a compute shader to update the pixels.
• egui integration (through bevy_egui) to show the pixels inside the UI.

Examples

A basic example,

use bevy::prelude::*;
use bevy_pixel_buffer::prelude::*;

fn main() {
    let size = PixelBufferSize {
        size: UVec2::new(32, 32),
        pixel_size: UVec2::new(16, 16),
    };

    App::new()
        .add_plugins((DefaultPlugins, PixelBufferPlugin))
        .add_systems(Startup, pixel_buffer_setup(size))
        .add_systems(Update, update)
        .run();
}

fn update(mut pb: QueryPixelBuffer) {
    pb.frame().per_pixel(|_, _| Pixel::random());
}
