+![License](https://img.shields.io/badge/license-0BSD%2FMIT%2FApache-blue.svg)
+![Tag](https://img.shields.io/github/v/tag/exvacuum/bevy_blacklight_material)
+![Build](https://img.shields.io/github/actions/workflow/status/exvacuum/bevy_blacklight_material/rust.yml)
+
+A plugin for the [Bevy Engine](https://bevyengine.org) which adds a "blacklight" material that is revealed by spot lights marked with a `Blacklight` component.
+
+Feel free to contribute if you want to improve this, it was thrown together pretty hastily so there's bound to be some errors or oversights.
+
+## Compatibility
+
+| Crate Version | Bevy Version |
+|--- |--- |
+| 0.1 | 0.14 |
+
+## Installation
+
+### crates.io
+```toml
+[dependencies]
+bevy_blacklight_material = "0.1"
+```
+
+### Using git URL in Cargo.toml
+```toml
+[dependencies.bevy_rustysynth]
+git = "https://github.com/exvacuum/bevy_blacklight_material.git"
+```
+
+## Usage
+
+In `main.rs`:
+```rs
+use bevy::prelude::*;
+
+fn main() {
+ App::new()
+ .add_plugins((
+ DefaultPlugins,
+ BlacklightPlugin,
+ ))
+ .run();
+}
+```
+Then you can create blacklight-emitting spotlights, and reveal-able surfaces, like this:
+```rs
+// Mesh with blacklight material
+commands.spawn(MaterialMeshBundle {
+ material: asset_server.add(BlacklightMaterial {
+ // base texture, color, etc
+ ..Default::default()
+ }),
+ ..Default::default()
+});
+
+
+// Blacklight
+commands.spawn((
+ Blacklight, // Marker component
+ SpotLightBundle {
+ spot_light: SpotLight {
+ // outer/inner angle, range
+ ..Default::default()
+ },
+ ..Default::default()
+ },
+));
+```
