Struct Scene

pub struct Scene { /* private fields */ }

Implementations

impl Scene

pub fn new() -> Scene

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn node(&self, id: NodeId) -> Result<&Node, SceneError>

pub fn nodes(&self) -> impl Iterator<Item = (NodeId, &Node)>

pub fn create( &mut self, name: impl Into<String>, local: Transform, parent: Option<NodeId>, ) -> Result<NodeId, SceneError>

pub fn set_local( &mut self, id: NodeId, local: Transform, ) -> Result<(), SceneError>

pub fn set_parent( &mut self, id: NodeId, parent: Option<NodeId>, ) -> Result<(), SceneError>

Reparent while retaining local TRS. Cycles and invalid handles are rejected before any links change. World-space position may change.

pub fn world_matrix(&self, id: NodeId) -> Result<[f32; 16], SceneError>

pub fn remove_subtree(&mut self, root: NodeId) -> Result<usize, SceneError>

pub fn prefab(&self, root: NodeId) -> Result<Prefab, SceneError>

Captures local transforms and hierarchy; external parent links are omitted.

pub fn instantiate( &mut self, prefab: &Prefab, parent: Option<NodeId>, ) -> Result<NodeId, SceneError>

pub fn clone_subtree( &mut self, root: NodeId, parent: Option<NodeId>, ) -> Result<NodeId, SceneError>

pub fn encode(&self) -> Result<Vec<u8>, SceneError>

GSC1 format: magic, u16 version, u32 count; each node has u32 parent (MAX=root), u16 UTF-8 name length, name bytes, and 10 little-endian f32 TRS values. Handles are remapped; serialized data never trusts slot generations.

pub fn decode(bytes: &[u8]) -> Result<Scene, SceneError>

Trait Implementations

impl Default for Scene

fn default() -> Scene

Returns the “default value” for a type.
