Struct bevy::input::gamepad::GamepadButton

pub struct GamepadButton {
    pub gamepad: Gamepad,
    pub button_type: GamepadButtonType,
}

A button of a Gamepad.

Usage

It is used as the generic T value of an ButtonInput and Axis to create bevy resources. These resources store the data of the buttons of a gamepad and can be accessed inside of a system.

Updating

The gamepad button resources are updated inside of the gamepad_button_event_system.

Fields

gamepad: Gamepad

The gamepad on which the button is located on.

button_type: GamepadButtonType

The type of the button.

Implementations

impl GamepadButton

pub fn new(gamepad: Gamepad, button_type: GamepadButtonType) -> GamepadButton

Creates a new GamepadButton.

Examples

let gamepad_button = GamepadButton::new(
    Gamepad::new(1),
    GamepadButtonType::South,
);
