The physical bounding volume of the object.
32-bit collision layer bitmask this object belongs to (default: 1).
32-bit collision mask specifying which layers this object interacts with (default: 0xFFFFFFFF).
Optional integer identifier for deterministic physics solver sorting and netcode lockstep.
Whether this object should generate bounds and participate in physics/raycasting. Defaults to true.
If true, this object acts as a trigger/sensor (fires trigger events without physical force).
OptionalonOptionalpendingSet by Scene on its hidden root object. Lets remove() notify the owning scene to queue
GPU-resource release for a discarded subtree even when called on a nested object directly
(someParent.remove(child)) instead of through Scene.remove() -- see remove()/add().
OptionalprefabName of the Maker prefab this node was instantiated from, if any -- provenance only, per
ADR 0010's Phase 2 "stamped copies" decision: no live link back to the source, just a record
of where this subtree came from. Round-tripped via the SW_prefab_instance glTF extension
(WorldWriter/GltfLoader).
OptionalquaternionOptionalrigidOptionaltagOptional app-defined category tag, for typed identification instead of matching on name.
Custom user-defined data storage dictionary.
ReadonlyuuidStatic ReadonlyinspectorBase schema every object exposes regardless of subclass -- see
collectInspectorSchema() in ./Inspectable.js, which merges this with whatever a
subclass (e.g. AbstractLight, AbstractMaterial) declares on top. Transform fields use
path since position/rotation/scale are nested Vector3D instances, not own properties.
Set only by WebGPU Hierarchical-Z occlusion culling (see docs/adr/0008-...), one frame
stale by design (mapAsync GPU->CPU readback is never synchronous). Unlike inFrustum,
NOT reset every frame -- only WebGPURenderer.applyPendingOcclusionResults() writes it, for
whichever objects it has a fresh readback for; everything else keeps its last known value.
Always false on WebGL1/WebGL2 (never written there), making Scene._collectVisible()'s
check a permanent no-op on those backends.
Returns an independent copy of this object's subtree -- own uuid, own transform, own
material (via AbstractMaterial.clone()), own behaviors (via Behavior.clone(), re-attached
so onAttach() runs against the new instance), and a recursive clone of every child. Used by
Maker's Duplicate command.
geometry and any texture references stay shared by reference -- immutable data, same as
every other "place another instance" workflow in the engine. parent/bounds reset (the
caller reparents and bounds recompute lazily); rigidBody is deliberately dropped rather
than shared, since two objects driven by the same live physics body would move together.
Known gap: skinned meshes aren't specially handled -- a cloned SkinnedMesh's skeleton
would still reference the original subtree's bones, not the freshly cloned ones alongside
it. Not a concern for Maker's realistic Duplicate targets (props, lights, prefab instances);
character rigs go through the Prefab/glTF pipeline instead.
Reads this object's position in world space, i.e. after resolving the full parent
chain -- unlike position, which is always local to its immediate parent. Requires
worldMatrix to be current (see updateMatrixWorld()).
Optional vector to write into, to avoid allocating one per call. If omitted, a shared module-level scratch is used and overwritten by the next call.
Traverses the object and all its descendants in depth-first order, executing the callback for each.
Static_StaticresetResets the global object ID generator (useful for deterministic tests).
A camera-facing sprite that swaps between the angle textures a prior
bakeImposter()call produced, picking whichever was baked closest to the current view angle. InheritsSprite's existing (non-instanced) CPU billboard path for the quad's own facing -- only the texture selection is new here.
