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)
