/bevy_input_map

Input Map aims to decouple game play code from device specific input api. This is achieved by providing apis that allows you to map game actions to device input events instead of directly handling device inputs.

Bevy Input Map

Input Map decouples gameplay code from device specific input api. By converting user inputs from different input hardware into game specific actions, eg. keyboard "Space" or joystick "A" can be mapped to "Jump" Action. This improves the overall code quality, by keeping the gameplay code separate from input code.

Usage

Add to Cargo.toml dependencies

[dependencies]
bevy_prototype_input_map = "0.2"

In code

fn main() {
    App::build()
        ...
        .add_plugin(InputMapPlugin::default())
        .add_startup_system(setup.system())
        .add_system(system.system())
        .run();
}

fn setup(
    mut input_map: ResMut<InputMap>,
) {
    input_map
    .bind_keyboard_pressed(KeyCode::Return, "SHOOT")
    .bind_mouse_motion(Axis::YNegative, "AIM_UP")
    .set_dead_zone("AIM_UP", 0.1)
}

// system
fn system(input_map: Res<InputMap>) {
    if input_map.is_action_active("SHOOT") {
        println!("Bang...");
    }

  • Ability to set custom strength curve

v0.1.1 (7 Sept, 2020)

  • minor* Readme changes
    • Had to bump the version to publish some readme changes

v0.1.0 (7 Sept, 2020)

  • Keyboard Key Mapping
    • Key press can now be binded to action
  • Mouse Button Mapping
    • Mouse button press can now be binded to action
  • Mouse Move Mapping
    • Mouse move event can now be mapped to action
  • Action Strength
    • Can now query strength of an action.
    • It will be in range of 0.0 - 1.0
    • Useful for analog inputs like joystick
  • Action Deadzone
    • For analog inputs sometimes it is meaningful to have a min threshold to avoid small input noise and to reduce sensitivity
