Crate pite_core 

Core scene-graph primitives for the Pite game engine: node handles, the hierarchical scene tree, properties, the node-type registry, signals, and lifecycle dispatch.

Defines foundational abstractions of the scene model with no direct dependencies on Python scripting (pite-script), rendering (pite-render), or scene file serialization (pite-scene). External subsystems plug in through the traits re-exported here to maintain modular architectural boundaries.

Modules

nodes

One file per node type. Each module owns its SCHEMA and PROPS.

schema

Schema definitions for engine node types, properties, inheritance, and validation.

Structs

Color

An 8-bit per channel sRGB color with straight (unmultiplied) alpha.

Node

A node instance within a NodeTree.

NodeDesc

Descriptor used to construct a Node, typically parsed from a .ptscn scene file.

NodeId

Unique identifier for a node within a NodeTree.

NodeTree

Hierarchical node tree managing node lifecycles and parent-child relationships.

NodeTypeRegistry

Registry managing instantiable node types and their corresponding construction factories.

Props

Key-value property map associated with a Node.

ScriptRef

Script attachment referencing a project-relative Python file and target class.

SignalDef

A registered signal definition specifying its event name and typed payload arguments.

SignalRegistry

Registry storing signal definitions for validation and dynamic dispatch.

Vec2

A 2D floating-point vector with x and y components.

Enums

CoreError

Errors produced by the core tree and its registries.

PropValue

Dynamically-typed property values supported by the engine’s scene and node model.

Constants

CUSTOM_PROP_TYPES

Supported type declarations permitted in manifest [props] tables.

Traits

LifecycleSink

Lifecycle dispatch interface through which engine systems invoke script lifecycle hooks.

Functions

global_position

Calculates the global world-space position of a node within a NodeTree.

Type Aliases

NodeFactory

Factory function closure producing a newly instantiated Node record for a given NodeId.

Result

Convenience alias for core results.
