_A composite effect applied to Bevy's 3D shapes example._

`bevy-vfx-bag` ([GitHub][bevy-vfx-bag-gh], [docs.rs][bevy-vfx-bag-docs])

is a visual effects library for the [Bevy][bevy] game engine.

It had its initial 0.1.0 release aligned with Bevy's recent 0.9.0 release.

Each effect has a plugin and effects are applied in order:

.add_plugin(BevyVfxBagPlugin) // Always needed

.add_plugin(RaindropsPlugin) // Shows rain on-screen

.add_plugin(ChromaticAberrationPlugin) // Skews color channels

.add_plugin(LutPlugin) // Allows using a look-up table to remap colors for

// having a specific "feel" to your game

.run();

The camera which receives these effects is marked as such:

.spawn(Camera3dBundle { ... })

.insert(PostProcessingInput) // Marks this camera for post processing usage

Effect settings can be changed at runtime:

fn update(time: Res<Time>, mut ca: ResMut<ChromaticAberration>) {

// Make the red color channel skew in a sinusoidal fashion

ca.magnitude_r = time.elapsed_seconds().sin();

}

The GitHub repository has examples and videos for all effects.

A complete rework of the plugin is underway for version 0.2.0, where the

main goal is to align with and use Bevy's render graph features,

including the new post processing double buffering feature which arrived

in 0.9.0.
