Bevy advanced inputs

This plugin provide functionality for bindig axises and keysets in bevy.

Create input types and bindings

#[derive(PartialEq, Eq, Hash, Clone, Copy)]
enum InputType {
    Editor,
    MainMenu,
    Game,
}

#[derive(PartialEq, Eq, Hash, Clone, Copy)]
enum Bindings {
    Hotkeys(HotkeysInput),
    Movement(MovementInput),
    Camera(CameraInput),
}

#[derive(PartialEq, Eq, Hash, Clone, Copy)]
enum MovementInput {
    Forward,
    Right,
    Up,
}
#[derive(PartialEq, Eq, Hash, Clone, Copy)]
enum CameraInput {
    Yaw,
    Pitch,
}

#[derive(PartialEq, Eq, Hash, Clone, Copy)]
enum HotkeysInput {
    Test,
}

Binding input

let mut config: InputConfig<Bindings> = InputConfig::new();
config.rebind_default_value(InputAxisType::KeyboardButton(KeyCode::S), -1.0);
config.rebind_default_value(InputAxisType::KeyboardButton(KeyCode::A), -1.0);
config.rebind_default_value(InputAxisType::KeyboardButton(KeyCode::Q), -1.0);
config.rebind_default_value(
    InputAxisType::GamepadButton(GamepadButtonType::LeftTrigger2),
    -1.0,
);

let mut set = UserInputSet::new()

set.begin_key(Bindings::Hotkeys(HotkeysInput::Test))
    .add(&[
        InputAxisType::KeyboardButton(KeyCode::Q),
        InputAxisType::KeyboardButton(KeyCode::W),
    ])
    .enable_repeat_all_for_reactivation();

set.begin_axis(Bindings::Movement(MovementInput::Forward))
    .add(InputAxisType::KeyboardButton(KeyCode::W))
    .add(InputAxisType::KeyboardButton(KeyCode::S))
    .add(
        InputAxisType::GamepadAxis(GamepadAxisType::LeftStickY),
        None,
    );

input_bindings.apply_config(&config);

Spawn entity with InputID

fn spawn_player(
    mut commands: Commands,
    mut input_bindings: ResMut<UserInputHandle<InputType, Bindings>>,
) {
    commands.spawn().insert_bundle(PlayerBundle {
        player: Player {},
        input_id: input_bindings.create_input_id(InputType::Editor),
    });
}

Handle input

fn process_player_input(
    input_bindings: Res<UserInputHandle<InputType, Bindings>>,
    query: Query<&InputID>,
) {
    query.for_each_mut(|input_component| {
        if let Some(input_handle) = input_bindings.to_handle(input_component) {
            if let Some(value) = input_handle.get_axis_value(Bindings::Movement(MovementInput::Forward))
            {}

            if let Some(value) = input_handle.get_key_state(Bindings::Hotkeys(HotkeysInput::Test))
            {}
        }
    });
}

Other Functions

Create new input id for handle it from input_bindings

input_bindings.create_input_id(InputType::Editor)

Switch to new input bindings set for InputID

input_bindings.switch_input(&component, InputType::Editor);

Remove unused input from input_bindings

input_bindings.stop_input_tracking(&component);

Take current input source(Mouse, Keyboard, Gamepad). Could be used for game widgets, when you want to add button icon to it

input_bindings.get_input_source()

Take mouse position and delta

input_bindings.get_mouse_postion();
input_bindings.get_mouse_delta();

Create input handle for InputID, take current input type for InputID

if let Some(input_handle) = input_bindings.to_handle(input_component){
    let current_input_type = input_handle.get_input_type();
}

Handle multiple gamepads provided by InputID number. First created InputID has id equal 0, second equal 1. And first connected gamepad also will have id equal 0, second equal 1. InputID limited only by u8 numbers.

Examples

See examples/common.rs for more information

Limitations

Currently, plugin didn't support touch inputs, because posssibly it should have gestures processor and algorythm for simply generate gesture and handle it. Also, gamepad values now filtered by abs(value) > 0.1
