Struct InputState 

pub struct InputState { /* private fields */ }

Input state tracker for keyboard, mouse, and other input devices.

This struct tracks the current state of all input devices and provides convenient methods for querying input state. It distinguishes between keys/buttons that are currently held, just pressed this frame, or just released this frame.

Implementations

impl InputState

pub fn new() -> Self

Create a new input state tracker.

pub fn handle_events(&mut self, events: &mut EventBatch)

Process events from the event batch.

This should be called each frame before querying input state.

pub fn end_frame(&mut self)

Clear per-frame state. Call this at the end of each frame.

pub fn is_key_pressed(&self, key: KeyCode) -> bool

Check if a key is currently pressed (held down).

pub fn is_key_just_pressed(&self, key: KeyCode) -> bool

Check if a key was just pressed this frame.

pub fn is_key_just_released(&self, key: KeyCode) -> bool

Check if a key was just released this frame.

pub fn is_any_key_pressed(&self, keys: &[KeyCode]) -> bool

Check if any of the given keys are pressed.

pub fn are_all_keys_pressed(&self, keys: &[KeyCode]) -> bool

Check if all of the given keys are pressed.

pub fn modifiers(&self) -> Modifiers

Get the current modifier key state.

pub fn is_shift_pressed(&self) -> bool

Check if Shift is held.

pub fn is_ctrl_pressed(&self) -> bool

Check if Ctrl (or Cmd on macOS) is held.

pub fn is_alt_pressed(&self) -> bool

Check if Alt (or Option on macOS) is held.

pub fn is_meta_pressed(&self) -> bool

Check if Meta (Windows key or Cmd on macOS) is held.

pub fn text_input(&self) -> &str

Get text input received this frame.

pub fn pressed_keys(&self) -> impl Iterator<Item = &KeyCode>

Get all keys currently pressed.

pub fn is_mouse_button_pressed(&self, button: MouseButton) -> bool

Check if a mouse button is currently pressed.

pub fn is_mouse_button_just_pressed(&self, button: MouseButton) -> bool

Check if a mouse button was just pressed this frame.

pub fn is_mouse_button_just_released(&self, button: MouseButton) -> bool

Check if a mouse button was just released this frame.

pub fn is_left_mouse_pressed(&self) -> bool

Check if left mouse button is pressed.

pub fn is_left_mouse_just_pressed(&self) -> bool

Check if left mouse button was just pressed.

pub fn is_right_mouse_pressed(&self) -> bool

Check if right mouse button is pressed.

pub fn is_right_mouse_just_pressed(&self) -> bool

Check if right mouse button was just pressed.

pub fn is_middle_mouse_pressed(&self) -> bool

Check if middle mouse button is pressed.

pub fn mouse_position(&self) -> Vec2

Get the current mouse position in window coordinates.

pub fn mouse_delta(&self) -> Vec2

Get the mouse movement delta since last frame.

pub fn scroll_delta(&self) -> Vec2

Get the scroll wheel delta since last frame.

Positive Y = scroll up, Negative Y = scroll down.

pub fn is_mouse_in_window(&self) -> bool

Check if the mouse cursor is inside the window.

pub fn horizontal_axis(&self) -> f32

Get horizontal input axis (-1, 0, or 1) from arrow keys or WASD.

pub fn vertical_axis(&self) -> f32

Get vertical input axis (-1, 0, or 1) from arrow keys or WASD.

pub fn movement_direction(&self) -> Vec2

Get movement direction as a normalized vector.

pub fn reset(&mut self)

Reset all input state.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InputState

fn default() -> Self

Returns the “default value” for a type.
