Struct InputState 

Source 
pub struct InputState {
    pub middle_down: bool,
    pub right_down: bool,
    pub shift_held: bool,
    pub ctrl_held: bool,
    pub prev_cursor: Option<(f32, f32)>,

    pub gizmo_starts: Vec<(EntityId, GizmoTransform)>,
}
Expand description

State of modifier keys + button drags that has to outlive a single frame. Lives on EditorApp and is mutated through this module.

Fields§

§middle_down: bool§right_down: bool§shift_held: bool§ctrl_held: bool§prev_cursor: Option<(f32, f32)>§last_cursor_pos: Option<(f32, f32)>

Last known cursor position in physical screen pixels — kept in sync with every WindowEvent::CursorMoved. Used by intercept_window_event to test whether a MouseInput event (which carries no position) lands inside the 3D viewport rect.

§gizmo_drag: Option<GizmoDrag>

The gizmo handle currently being dragged, if any.

§gizmo_starts: Vec<(EntityId, GizmoTransform)>

Transforms the selection had when that drag began. A drag resolves against these rather than against the live values, so it cannot accumulate drift over a long gesture.

Implementations§

Source§

impl InputState

Source

pub fn release_all(&mut self)

Drops every held button and modifier.

Called when the window loses focus: a release that happens while another application is in front never reaches us, so without this the flag stays set forever — Alt-Tab with the middle button down and the camera orbits on plain mouse movement from then on. A stuck ctrl_held is quieter and worse: it disables the gizmo shortcuts, which just stop working.

Source

fn end_gizmo_drag(&mut self)

Drops any manipulation in progress, leaving the entities where the last resolved delta put them.
