Struct InputSystem 

pub struct InputSystem { /* private fields */ }

An input system that wraps InputState and provides additional functionality.

Implementations

impl InputSystem

pub fn new() -> Self

Create a new input system.

pub fn state(&self) -> &InputState

Get the input state.

pub fn state_mut(&mut self) -> &mut InputState

Get mutable access to the input state.

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

Process events from the event batch.

pub fn end_frame(&mut self)

Clear per-frame state.

Methods from Deref<Target = InputState>

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

impl Default for InputSystem

fn default() -> Self

impl Deref for InputSystem

type Target = InputState

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for InputSystem

fn deref_mut(&mut self) -> &mut Self::Target
