## ✨ Features

- Provides smooth interpolation for movement without sacrificing camera position.

- Includes an optional HUD overlay to display important information like FOV and FPS.

- Automatically grabs cursor when <kbd>MMB</kbd>/<kbd>RMB</kbd> is held.

- Allows complete control over movement via <kbd>LShift</kbd> prefixed controls.

## 📦 Installation

1.  Install the crate using `cargo`

    ```bash
    cargo add bevy_prank
    ```

2.  Add `PrankPlugin` to your app

    ```rust
    use bevy::prelude::*;
    use bevy_prank::prelude::*;

    fn main() {
        App::new()
            // ...
            .add_plugins((DefaultPlugins, PrankPlugin::default()))
            // ...
            .run();
    }
    ```

## 🚀 Usage

Spawn a `Camera3dBundle` along with a `Prank3d` component

```rust
use bevy::prelude::*;
use bevy_prank::prelude::*;

fn setup(mut commands: Commands) {
    commands.spawn((
        Prank3d::default(),
        Camera3dBundle::default(),
    ));
}
```
