Module scene_tree 

Scene Tree panel — the entity hierarchy: search, foldable rows with a chevron and a type icon, and the branded gold selection bar.

EditorState::hidden_entities still dims the rows it names, but nothing populates it: the visibility eye was removed because it only greyed the row while the object kept rendering. The set is left in place as the seam a component-activation model would plug into.

Functions

count_scene_nodes 🔒

Recursively counts every visible node in a subtree (self + children).

count_visible_nodes 🔒

Counts the rows a forest actually shows, stopping at folded nodes.

dispatch_asset_drop 🔒

Routes an asset dropped onto the hierarchy to the right pending_* action, mirroring the viewport’s drop dispatch. Meshes spawn at the world origin (a tree has no 3D drop point), prefabs instantiate, scenes load, and a texture/material assigns to the target row (or the selection).

entity_icon 🔒

filter_scene_node 🔒

Filters a SceneNode against a lowercase needle. Returns Some(node) when the node’s own name contains the needle (subtree kept intact) or when any descendant matches (only matching descendants kept). Returns None when neither the node nor any descendant matches.

find_node_name 🔒

Finds an entity’s display name in a SceneNode forest.

pack_entity 🔒

Packs an EntityId into a u64 for drag-and-drop payloads. Layout: high 32 = generation, low 32 = index. Also used by the asset browser’s drop handler to ingest entity drags from the scene tree (drop = create prefab in the current folder).

payload_is_entity 🔒

true when payload is not one of the asset-browser’s dedicated drag tags (the type-agnostic asset-tile tag). Lets receivers disambiguate scene-tree entity payloads from asset-tile payloads on the same dnd_take_drop_payload channel.

render_node 🔒

unpack_entity 🔒

Inverse of pack_entity.
