bevy_editor_pls

⚠️ This is very much work in progress: Take a look at the missing features to see if your use case isn't yet supported.

Adds debug tools to your bevy game, including

hierarchy view and component inspector
separate editor camera
some builtin editor panels for diagnostics, debug settings
scene export

This is not, and isn't meant to be, comparable to the actual editor bevy will end up with. bevy_editor_pls attempts to get the low hanging fruits by adding editor UI to the game executable, without having all the complexity that comes with having a proper well-designed editor architecture.

How to use:

Add the EditorPlugin:

+use bevy_editor_pls::prelude::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
+       .add_plugin(EditorPlugin)
        ...
        .run();
}

Custom editor panels

fn main() {
    App::new()
        ...
        .add_editor_window::<MyEditorWindow>()
        ...
        .run();
}

pub struct MyEditorWindow;
impl EditorWindow for MyEditorWindow {
    type State = ();
    const NAME: &'static str = "Another editor panel";

    fn ui(world: &mut World, cx: EditorWindowContext, ui: &mut egui::Ui) {
        let currently_inspected = cx.state::<HierarchyWindow>().unwrap().selected;

        ui.label("Anything can go here");
    }
}

Controls

The default controls are:

E to toggle the editor
Ctrl+Enter to pause/unpause time
Click (or Ctrl+Click when not in editor) to select mesh
Click + Drag for the pan/zoom 2d camera
Double click on the menu bar to go fullscreen

Cameras:

2d (Pan/Zoom): any mouse button to pan, scroll to zoom
3d (Free): WASD + Ctrl/Shift + Shift for a speed boost for the free 3d camera
3d (Pan/Orbit): Right click to rotate around focus, Middle mouse button to pan

Changing the default controls

use bevy_editor_pls::EditorPlugin;
use bevy_editor_pls::controls;
use bevy_editor_pls_default_windows::hierarchy::picking::EditorRayCastSource;

fn main() {
    App::new()
        // ..
        .add_plugin(EditorPlugin)
        .insert_resource(editor_controls())
        .add_startup_system(set_cam3d_controls)
        // ..
        .run();
}

fn editor_controls() -> EditorControls {
    let mut editor_controls = EditorControls::default_bindings();
    editor_controls.unbind(controls::Action::PlayPauseEditor);

    editor_controls.insert(
        controls::Action::PlayPauseEditor,
        controls::Binding {
            input: controls::UserInput::Single(controls::Button::Keyboard(KeyCode::Escape)),
            conditions: vec![controls::BindingCondition::ListeningForText(false)],
        },
    );

    editor_controls
}

fn set_cam3d_controls(
    mut query: Query<&mut bevy_editor_pls::default_windows::cameras::camera_3d_free::FlycamControls>,
) {
    let mut controls = query.single_mut();
    controls.key_up = KeyCode::Q;
    controls.key_down = KeyCode::E;
}

Missing features

scene import
transform gizmos
visualization of invisible entities in editor (to see where the camera is for example)
