The lysa.nodes sub-module — scene-graph node types and utilities.

Enums & Constants
enum	AnimationPlayerEvent
	Event type constants emitted by AnimationPlayer nodes.

enum	CameraProjectionType
	Constants for the camera projection mode.

enum	CharacterEventType
	Event type constants emitted by Character nodes.

enum	NodeType
	Integer constants identifying the concrete type of a node.

enum	ProcessMode
	Constants that control when a node receives process and input callbacks.

Structures
struct	Collision
	Data describing a single physics collision contact.

struct	Light
	Base class for all light-emitting nodes.

struct	LoaderEventType
	Event type constants emitted by the async scene Loader.

struct	OmniLight
	A point (omnidirectional) light that emits equally in all directions.

struct	RayCast
	A node that continuously casts a ray from its origin along its local -Z axis and reports the first hit.

struct	RayCastHit
	Extended ray cast result that includes scene-node hit data in addition to the geometric hit.

struct	SpotLight
	A spot light that emits within a cone defined by inner and outer cutoff angles.

struct	TimerEvent
	Event type constants emitted by Timer nodes.

struct	Viewport
	A node that defines a viewport and scissor region for the scene camera.

Classes
class	AnimationPlayer
	A node that plays skeletal or property animations from an asset's animation library.

class	Camera
	A scene camera node providing perspective or orthographic projection.

class	Character
	A capsule-based character controller for first/third-person movement, driven via velocity each physics tick.

class	CollisionArea
	A trigger volume that detects overlapping physics bodies without applying forces.

class	CollisionObject
	Base class for all physics collision objects. Provides shape and layer management.

class	DirectionalLight
	A directional light with parallel rays (e.g. sunlight). Supports cascaded shadow maps.

class	Environment
	A node that sets the ambient light for its scene.

class	KinematicBody
	A physics body moved programmatically via transforms rather than forces (e.g. moving platforms).

class	Loader
	Utility for loading scene files synchronously or asynchronously.

class	MeshInstance
	A renderable node that pairs a GPU Mesh with a scene-tree transform and per-surface material overrides.

class	Node
	The base class for all scene-tree nodes. Provides transform, hierarchy, grouping, and lifecycle callbacks.

class	PhysicsBody
	Base class for physics bodies that participate in the simulation.

class	RigidBody
	A fully simulated rigid body driven by the physics engine (mass, forces, impulses).

class	SceneTree
	The root container for a scene hierarchy; manages the node tree, camera, and rendering attachment.

class	StaticBody
	A non-moving physics body (walls, floors, terrain). Other bodies collide with it but it is never displaced.

class	Timer
	A countdown timer node that fires a TIMEOUT event when it expires.
