Bevy Debug Menu

This crate adds a debug menu to your Bevy game. It can show your diagnostics, and explore and edit the current entities and resources.

Usage

• use bevy from a recent master branch

[patch.crates-io]
bevy = { git = "https://github.com/bevyengine/bevy", rev = "e6e23fdfa97b0ebfad3495407d9dff27d75ab843" }

• add bevy_debug_menu as a dependency

[dependencies]
bevy_debug_menu = { git = "https://github.com/Davier/bevy_debug_menu" }

• add the DebugMenuPlugin to your bevy app
• launch the app and press F10 to show or hide the menu

Optional setup

• derive Reflect, ReflectComponent and ReflectResource on your types
• adapt your game to stop processing keyboard inputs when editing entities by listening to FocusedEvent and UnfocusedEvent
• you need to use release mode to have descent frame rate, at least for your dependencies:

[profile.dev.package."*"]
opt-level = 3

• reflection on resources and enum types can be enabled with a bevy fork (see #1260 and #1347):

[dependencies]
bevy_debug_menu = { git = "https://github.com/Davier/bevy_debug_menu", features = ["extra"] }
[patch.crates-io]
bevy = { git = "https://github.com/Davier/bevy", branch = "extra" }

Warnings

Example

use bevy::prelude::*;

fn main() {
    App::build()
        .add_plugins(DefaultPlugins)
        .add_plugin(bevy_debug_menu::DebugMenuPlugin)
        // This is unnecessary if you already initialize the UI camera in your game
        .add_startup_system(bevy_debug_menu::setup_ui_camera.system())
        .run();
}

TODO

• stable order for all items
• search by resource type, component type, entity Name and entity Label
• remove resource, entity, component
• load/save scene
• list and spawn loaded scenes
• integration with bevy_mod_picking
