Getting Started To run the editor, use the following command:

cargo run

To run platformer example, use the following command:

cargo run run --example platformer --features bevy_xpbd_3d

Usage - Game

The following explains how to integrate space_editor as a game plugin to use the created prefabs in your game.


Add this line to your Cargo.toml file

space_editor = "0.4.0"

# For now it is recomendended to use the following patches of the libraries we are using
bevy-inspector-egui ={ git = "https://github.com/naomijub/bevy-inspector-egui.git" }

Prefab spawn system

To utilize the prefab spawn system, simply add the plugin to your application as follows:


For spawning, use the PrefabBundle:


(More code at examples/spawn_prefab.rs)

Usage - Editor

The editor is a ready to use executable that can be used and altered at your own necessity. It's base configuration is as follows, with simple_editor_setup:

fn main() {
        .add_systems(Startup, simple_editor_setup)

(Code from main.rs)

Editor usage strategy

  • Fork this repo.
  • Create a branch to keep up to date with project updates and addressed bugs.
  • Editor is executed with editor feature.
  • Feel free to upstream your examples and community modules to enrich space-editor


More detailed information in docs/README.md

Custom types can be added to the editor gui and prefab spawn system with just a single line:

use editor::prelude::EditorRegistryExt;


The representation of components in the editor UI can also be customized by bevy_inspector_egui library.


Custom Events can be added to the editor UI with the following:

#[derive(Event, Default, Resource, Reflect, Clone)]
pub struct Name;

use editor::prelude::EditorRegistryExt;


One limitation is that events must implement Event, Default, Resource, Reflect, Clone, with Resource reflected. Once registered, events can be sent using the Event Dispatcher tab.

Obs: editor already handles internally objects registration and initialization:

register_type::<T>() and init_resource::<T>()

To disable this, use feature no_event_registration.


A prefab is simply a Bevy scene serialized to a readable and editable RON format. However, it needs to be spawned through PrefabBundle to activate custom logic such as adding global transforms to an object.

More documentation can be found at the docs folder

2D Mode support

SpaceEditor can handle most 2D bevy elements, such as 2D Camera, 2D meshes and Sprites.

Game mode can be changed between 3D and 2D in settings > GameMode. This changes the editor camera configuration.
