    pub id: GamepadId,

Expand description

Snapshot of one gamepad’s state. Buttons are a bitset (bit n = the GamepadButton with discriminant n); axes are explicit fields. All POD / Copy, so it crosses the FFI by value.

Fields§

§id: GamepadId

Which pad this snapshot is for.

§connected: bool

false once the pad disconnects (the manager keeps the last slot so a callback can observe the disconnect).

§buttons: u32

Pressed-button bitset — bit n set ⇔ the GamepadButton with discriminant n is held. Read via GamepadState::is_pressed.

§left_stick_x: f32

Left stick X in [-1, 1].

§left_stick_y: f32

Left stick Y in [-1, 1].

§right_stick_x: f32

Right stick X in [-1, 1].

§right_stick_y: f32

Right stick Y in [-1, 1].

§left_z: f32

Left trigger pressure in [0, 1].

§right_z: f32

Right trigger pressure in [0, 1].

Implementations§

Source §

impl GamepadState

Source

pub const fn empty(id: GamepadId) -> GamepadState

An empty (disconnected) state for id — all buttons up, axes zero.

Source

pub const fn is_pressed(&self, button: GamepadButton) -> bool

Whether button is currently held.

Source

pub const fn axis(&self, axis: GamepadAxis) -> f32

The current value of axis (sticks [-1, 1], triggers [0, 1]).
