bevy_dolly

Static	Pinned

bevy_dolly is a prototype plugin using h3r2tic's powerful crate: dolly, implemented for bevy.

âš  Feedback - Bevydolly's API is still being revised, so feedback on ergonomics and DX is highly appreciated_ âš 

It is important to note that dolly is a way to control the movement of the camera and thus, not the camera component itself.

Dolly requires two steps to function:

1. Creating a Rig we are able to define drivers on which the dolly can enact, these drivers can both be constraints and functionality.
2. A marker component that is registered on both the Camera and the Rig.

What are drivers?

Explain what drivers are

To read more about the different drivers.

```rs

[derive(Component)]

struct MainCamera;

fn main() { App::new() .addplugins(DefaultPlugins) .addstartupsystem(setup) //.. .addsystem(Dolly::::update_active) //.. .run(); } ```

rs // In your setup system fn setup( mut commands: Commands, ) { commands.spawn(( MainCamera, // The rig tag Rig::builder() .with(Position::new(Vec3::ZERO)) .with(YawPitch::new().yaw_degrees(45.0).pitch_degrees(-30.0)) .with(Smooth::new_position(0.3)) .with(Smooth::new_rotation(0.3)) .with(Arm::new(Vec3::Z * 4.0)) .build(), Camera3dBundle::default(), )); }

Helpers

This plugin currently also provides some helper plugins, which. They are enabled by default but are not needed and can be removed when setting up bevy_dolly's dependency:

toml [dependencies] bevy_dolly = { version = "0.0.1", default-features = false }

Note this will also remove the bevy_dolly's extended drivers and add features = ["drivers"], to include the drivers back.

Examples

To see how works in Bevy in practice, please look at this repository's examples.

Alternatives

There is a bunch of other bevy camera controllers that are worth checking out, especially if you are just starting out learning bevy:

• bevyfpscontroller - A Fps controller with crouching, sprinting, flymode and more
• smooth-bevy-cameras - 3 Smooth Camera controllers: Fps, Orbit or Unreal
• bevy_spectator - A spectator camera controller
• bevy_flycam - A simple fly camera
• bevyflycamera - A advanced fly camera
• bevy_pancam - 2D Click and Drag - Style camera movement
• bevyconfigcam - Plugin that enables to use collection of different camera controllers at runtime, uses bevy_dolly as the backend

Contributing

Yes this project is still very much WIP, so PRs are very welcome.
The dolly dependency used is a slightly patched submodule, so to build the crate locally you must first run the following:

bash git submodule update --init --recursive
