A straightforward but robust input-action manager for Bevy.

Inputs from various input sources (keyboard, mouse and gamepad) are collected into a common ActionState on your player entity, which can be conveniently used in your game logic.

The mapping between inputs and actions is many-to-many, and easily configured and extended with the InputMap components on each player entity. A single action can be triggered by multiple inputs (or set directly by UI elements or gameplay logic), and a single input can result in multiple actions being triggered, which can be handled contextually.

Supported Bevy Versions

  • Full keyboard, mouse and joystick support for button-like and axis inputs
  • Dual axis support for analog inputs from gamepads and joysticks
  • Bind arbitrary button inputs into virtual DPads
  • Effortlessly wire UI buttons to game state with one simple component!
    • When clicked, your button will press the appropriate action on the corresponding entity
  • Store all your input mappings in a single InputMap component
    • No more bespoke Keybindings<KeyCode>, Keybindings<Gamepad> headaches
  • Look up your current input state in a single ActionState component
    • That pesky maximum of 16 system parameters got you down? Say goodbye to that input handling mega-system
  • Ergonomic insertion API that seamlessly blends multiple input types for you
    • Can't decide between input_map.insert(Action::Jump, KeyCode::Space) and input_map.insert(Action::Jump, GamepadButtonType::South)? Have both!
  • Full support for arbitrary button combinations: chord your heart out.
    • input_map.insert_chord(Action::Console, [KeyCode::ControlLeft, KeyCode::Shift, KeyCode::KeyC])
  • Sophisticated input disambiguation with the ClashStrategy enum: stop triggering individual buttons when you meant to press a chord!
  • Create an arbitrary number of strongly typed disjoint action sets by adding multiple copies of this plugin: decouple your camera and player state
  • Local multiplayer support: freely bind keys to distinct entities, rather than worrying about singular global state
  • Networked multiplayer support: serializable structs, and a space-conscious ActionDiff representation to send on the wire
  • Powerful and easy-to-use input mocking API for integration testing your Bevy applications
    • app.send_input(KeyCode::KeyB) or world.send_input(UserInput::chord([KeyCode::KeyB, KeyCode::KeyE, KeyCode::KeyV, KeyCode::KeyY])
  • Control which state this plugin is active in: stop wandering around while in a menu!
  • Leafwing Studio's trademark #![forbid(missing_docs)]


  • Gamepads must be manually assigned to each input map: read from the Gamepads resource and use InputMap::set_gamepad.

Getting started

  1. Add leafwing-input-manager to your Cargo.toml.
  2. Create an enum of the logical actions you want to represent, and derive the Actionlike trait for it.
  3. Add the InputManagerPlugin to your App.
  4. Add the InputManagerBundle to your player entity (or entities!).
  5. Configure a mapping between your inputs and your actions by modifying the InputMap component on your player entity.
  6. Read the ActionState component on your player entity to check the collected input state!
use bevy::prelude::*;
use leafwing_input_manager::prelude::*;

fn main() {
        // This plugin maps inputs to an input-type agnostic action-state
        // We need to provide it with an enum which stores the possible actions a player could take
        // The InputMap and ActionState components will be added to any entity with the Player component
        .add_systems(Startup, spawn_player)
        // Read the ActionState in your systems using queries!
        .add_systems(Update, jump)

// This is the list of "things in the game I want to be able to do based on input"
#[derive(Actionlike, PartialEq, Eq, Hash, Clone, Copy, Debug, Reflect)]
enum Action {

struct Player;

fn spawn_player(mut commands: Commands) {
    // Describes how to convert from player inputs into those actions
    let input_map = InputMap::new([(Action::Jump, KeyCode::Space)]);

// Query for the `ActionState` component in your game logic systems!
fn jump(query: Query<&ActionState<Action>, With<Player>>) {
    let action_state = query.single();
    // Each action has a button-like state of its own that you can check
    if action_state.just_pressed(&Action::Jump) {
        println!("I'm jumping!");
