Description

Core Entity-Component-System architecture.

This module provides the foundational classes for the composition-based game architecture. It includes entity base classes (GameObject, Component, CloneableComponent), system infrastructure (System), and query utilities (GameObjectFilter, GameObjectView).

Functions

registerComponents()

void helios::engine::ecs::registerComponents ()

inline

Registers all lifecycle components with the ComponentReflector.

Definition at line 17 of file registry.ixx.

17 inline void registerComponents() {

18 using R = helios::engine::ecs::ComponentReflector;

20 R::registerType<components::HierarchyComponent>();

Variables

InitialVersion

auto helios::engine::ecs::InitialVersion = helios::engine::common::types::VersionId{1}

constexpr

The initial version assigned to newly created entities.

Versions start at 1 to distinguish valid handles from default-initialized handles that may have a version of 0.

Definition at line 28 of file EntityRegistry.ixx.

28 constexpr auto InitialVersion = helios::engine::common::types::VersionId{1};

Referenced by helios::engine::ecs::EntityRegistry::create.

Tombstone

auto helios::engine::ecs::Tombstone = helios::engine::ecs::types::EntityTombstone

constexpr

Sentinel value indicating an empty slot in the sparse array.

Aliased from `helios::engine::ecs::types::EntityTombstone`.

Definition at line 73 of file SparseSet.ixx.

73 constexpr auto Tombstone = helios::engine::ecs::types::EntityTombstone;
