}

Complete snapshot of all input this frame.

Created and updated by the Pipeline each frame. Game code receives a &mut ProofEngine whose .input field holds this value.

Fields

keys_pressed: HashSet<Key>

All keys currently held down.

keys_just_pressed: HashSet<Key>

Keys that transitioned to pressed this frame.

keys_just_released: HashSet<Key>

Keys that transitioned to released this frame.

mouse_x: f32

Cursor X in window pixels (top-left origin).

mouse_y: f32

Cursor Y in window pixels (top-left origin).

mouse_delta: Vec2

Mouse movement since last frame, in pixels.

mouse_ndc: Vec2

Cursor in normalized device coordinates ([-1, 1], Y-up).

mouse_left: bool

mouse_left_just_pressed: bool

mouse_left_just_released: bool

mouse_right: bool

mouse_right_just_pressed: bool

mouse_right_just_released: bool

mouse_middle: bool

mouse_middle_just_pressed: bool

scroll_delta: f32

Vertical scroll delta this frame (positive = scroll up / zoom in).

window_resized: Option<(u32, u32)>

Set if the window was resized this frame. Contains (width, height).

quit_requested: bool

Set if the user requested a quit (Alt+F4, OS close button).

Implementations

impl InputState

pub fn new() -> Self

pub fn is_pressed(&self, key: Key) -> bool

Returns true while the key is held down.

pub fn just_pressed(&self, key: Key) -> bool

Returns true on the frame the key was first pressed.

pub fn just_released(&self, key: Key) -> bool

Returns true on the frame the key was released.

pub fn any_pressed(&self, keys: &[Key]) -> bool

Returns true if any of the given keys are held.

pub fn all_pressed(&self, keys: &[Key]) -> bool

Returns true if all of the given keys are held simultaneously.

pub fn shift(&self) -> bool

Returns true if a modifier key (Shift, Ctrl, Alt) is held.

pub fn ctrl(&self) -> bool

pub fn alt(&self) -> bool

pub fn mouse_pos(&self) -> Vec2

Mouse position as a Vec2 in window pixels.

pub fn mouse_left_down(&self) -> bool

Returns true while the left mouse button is held.

pub fn mouse_left_click(&self) -> bool

Returns true on the frame the left button was first pressed.

pub fn mouse_right_down(&self) -> bool

Returns true while the right mouse button is held.

pub fn mouse_right_click(&self) -> bool

Returns true on the frame the right button was first pressed.

pub fn mouse_drag(&self) -> bool

Returns true if the mouse is being dragged with the left button held.

pub fn mouse_delta_ndc(&self, window_width: u32, window_height: u32) -> Vec2

Returns the mouse delta scaled to NDC space (suitable for camera control).

pub fn wasd(&self) -> Vec2

Returns a movement vector from WASD keys: (right, up) in [-1, 1]. W/S → Y axis, A/D → X axis.

pub fn arrows(&self) -> Vec2

Returns a normalized movement vector from arrow keys.

pub fn clear_frame(&mut self)

Clear all per-frame transient state. Called by the pipeline before processing events.

Trait Implementations

impl Clone for InputState

fn clone(&self) -> InputState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for InputState

fn default() -> InputState

Returns the “default value” for a type.
