Implementations

impl ViewportPanel

pub fn new( handle: ViewportTextureHandle, state: Arc<Mutex<EditorState>>, camera: Arc<Mutex<EditorCamera>>, theme: UiTheme, ) -> Self

fn has_camera_node(nodes: &[SceneNode]) -> bool

fn paint_camera_preview( &self, ui: &mut dyn UiBuilder, viewport_min: [f32; 2], viewport_size: [f32; 2], )

fn paint_axis_gizmo( &self, ui: &mut dyn UiBuilder, viewport_min: [f32; 2], viewport_size: [f32; 2], )

impl ViewportPanel

fn paint_tool_pill(&self, ui: &mut dyn UiBuilder, viewport_min: [f32; 2])

fn paint_transport_pill( &self, ui: &mut dyn UiBuilder, viewport_min: [f32; 2], viewport_size: [f32; 2], )

The transport — play, pause, stop — floating at the bottom centre.

Each button’s state is derived from PlayMode, so the control always tells the truth about what the engine is doing: a disabled Stop while editing means there is genuinely nothing to stop. Buttons that cannot act are dimmed and swallow their clicks rather than silently no-op.

fn dispatch(&self, action: &str)

Queues a menu action for the app to pick up next tick.

fn paint_stats_card( &self, ui: &mut dyn UiBuilder, viewport_min: [f32; 2], viewport_size: [f32; 2], )

fn paint_play_mode_indicator( &self, ui: &mut dyn UiBuilder, viewport_min: [f32; 2], viewport_size: [f32; 2], )

fn dispatch_asset_drop( &self, ui: &dyn UiBuilder, entry: &AssetEntry, viewport_min: [f32; 2], viewport_size: [f32; 2], )

Routes a dropped asset by its declared type. Prefabs/scenes spawn or load; a mesh materialises at the unprojected drop point; a texture or material is assigned to the current selection.

fn compute_drop_point( &self, ui: &dyn UiBuilder, viewport_min: [f32; 2], viewport_size: [f32; 2], ) -> [f32; 3]

Unprojects the drop point onto the ground plane (y = 0). Falls back to a fixed distance along the ray when the ray is parallel to the ground or the pointer position is unavailable (uses the viewport centre then).

fn paint_diamond_watermark( &self, ui: &mut dyn UiBuilder, viewport_min: [f32; 2], viewport_size: [f32; 2], )

Trait Implementations

impl EditorPanel for ViewportPanel

fn id(&self) -> &str

Unique identifier (used for dock serialization and lookup).

fn title(&self) -> &str

Human-readable title shown in the tab / panel header.

fn ui(&mut self, ui: &mut dyn UiBuilder)

Build the panel contents for the current frame.

fn preferred_size(&self) -> Option<f32>

Preferred size hint, in logical points.
