# Bevy Blendy Cameras

## Summary

Editor like cameras controls and features inspired by Blender's viewport 
camera controls.

## Features

- Pan/orbit/zoom camera controls with "zoom to mouse position" and 
  "auto depth" options
- Fly camera controls
- Move to viewpoints (top, bottom, front, back, left, right)
- Frame entities into view
- Grab cursor or wrap cursor around the viewport during orbit and fly rotation
- Egui support

## TODO

- Clean code
- Make fly mode works with orthographic projection
- Support "Auto depth" for pan movement. So that the result of the raycast under the mouse coursor always stays under the mouse cursor during pan, if no cursor grab/wrap.
- Make the raycast used for "Auto depth" respect the materials backface culling setting. Maybe optionally because this might conflict with other raycast options used for other uses by the user.

## Default Controls

### OrbitCameraController

- Middle mouse drag - Orbit
- Shift + Middle mouse drag - Pan
- Scroll wheel - Zoom

### FlyCameraController

- Middle mouse drag - Rotate
- Scroll wheel - Change movement speed
- E - Move forward (zoom)
- D - Move backward (unzoom)
- S - Move to the left
- F - Move to the right
- W - Move to the bottom
- R - Move to the top

## Quick Start

Add the plugin:
```rust ignore
.add_plugins(BlendyCamerasPlugin)
```

Add the controllers components to a camera:
``` rust ignore
commands.spawn((
    Camera3d::default() ,
    Transform::from_translation(Vec3::new(0.0, 1.5, 5.0)),
    OrbitCameraController::default(),
    FlyCameraController {
        is_enabled: false,
        ..default()
    },
));
```
Adding both controller is not required. If you need just one, only add this one.
If you want to switch from one to another, adding both before the switch is OK,
just make sure only one is enabled. Otherwise both will react to inputs.

Check out the [basic example](https://github.com/thmxv/bevy_blendy_cameras/tree/master/examples/basic.rs) 
to see more functionalities.

## Cargo Features

- `bevy_egui` (optional): Ignore input when `egui` has the focus
