NOTE* Kurinji is not being actively maintained/developed. Please try other plugins for newer Bevy versions. Reason for discontinuing is Bevy is still in its infacy and not very mature i.e. lot of breaking API change between releases requiring more time and effort. Combined with the lack of motivation on my part to continously update. I have decided to pause any development on Bevy plugins for the time being.

Thank you

Kurinji Input Map

Input map plugin for bevy

(Note* Previously called bevy_prototype_input_map)

Decouples gameplay code from device specific input api. Converts user inputs from different input hardware into game specific actions, eg. keyboard "Space" or joystick "A" can be mapped to "Jump" Action.

Usage

Add to Cargo.toml dependencies

[dependencies]
kurinji = "*"

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

fn setup(
    mut kurinji: ResMut<Kurinji>,
) {
    // with data 
    // refer "example/config/gamepad.ron"
    let binding_ron = fs::read_to_string("example/config/gamepad.ron").unwrap()
    kurinji.set_bindings_with_ron(&binding_ron);

    // or

    // via code
    kurinji
    .bind_keyboard_pressed(KeyCode::Return, "SHOOT")
    .bind_mouse_motion(Axis::YNegative, "AIM_UP")
    .set_dead_zone("AIM_UP", 0.1)
}

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