bevypixelbuffer

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,

```rust use bevy::prelude::; use bevy_pixel_buffer::prelude::;

fn main() { let size = PixelBufferSize { size: UVec2::new(32, 32), // amount of pixels pixel_size: UVec2::new(16, 16), // size of each pixel in the screen };

App::new()
    .add_plugins(DefaultPlugins)
    .add_plugin(PixelBufferPlugin)  // Add this plugin
    .add_startup_system(pixel_buffer_setup(size)) // Setup system
    .add_system(update)
    .run()

}

fn update(mut pb: QueryPixelBuffer) { // Set each pixel to a random color pb.frame().perpixel(|, _| Pixel::random()); } ```
