Smooth pixel-perfect camera for Bevy

bevy_smooth_pixel_camera

A bevy plugin that adds a simple smooth pixel camera.

The smoothing is based on this video from aarthificial which explains how it works pretty nicely: https://youtu.be/jguyR4yJb1M

This method allows for smooth camera movement while retaining the pixel perfection of low resolution rendering.

Usage

1. Add the bevy_smooth_pixel_camera crate to your project.

   cargo add bevy_smooth_pixel_camera

2. Add the PixelCameraPlugin and set the ImagePlugin to default_nearest.

   use bevy::prelude::*;
   use bevy_smooth_pixel_camera::prelude::*;
   
   App::new().add_plugins((
       DefaultPlugins.set(ImagePlugin::default_nearest()),
       PixelCameraPlugin
   )).run();

3. Add a pixel pefect camera to your scene.

   use bevy::prelude::*;
   use bevy_smooth_pixel_camera::prelude::*;
   
   fn setup(mut commands: Commands) {
       commands.spawn((
           Camera2dBundle::default(),
           PixelCamera::from_size(ViewportSize::PixelFixed(4))
       ));
   }

4. That should be it! Make sure you move your camera via the PixelCamera.subpixel_pos property instead of the Transform component.
