Description

helios::engine::runtime::world

World state management, resource registry, and per-frame update context.

Overview

This module provides the core classes for managing runtime game state. GameWorld is the root container owning the entity system, the ResourceRegistry for type-indexed O(1) resource access, the current Level, and the Session. UpdateContext provides the per-frame context passed to systems during updates.

Key Classes

Class	Purpose
GameWorld	Central game state container for entities, resources, and the active level
ResourceRegistry	Type-indexed store for Managers and CommandBuffers with O(1) lookup
Session	Cross-frame state tracking (game/match states, scores)
Level	Game level with world bounds and root scene node
UpdateContext	Per-frame context with delta time, event buses, and queueCommand<T>()
SystemRegistry	ConceptModelRegistry<System, SystemTypeId> alias for system storage
ManagerRegistry	ConceptModelRegistry<Manager, ResourceTypeId> alias for manager storage
Manager	Type-erased wrapper for deferred operation handlers (Concept/Model pattern)

Usage

 // Create world and register resources

 helios::engine::runtime::world::GameWorld gameWorld;

 auto& poolMgr = gameWorld.registerResource<GameObjectPoolManager>();

 auto& spawnMgr = gameWorld.registerResource<SpawnManager>();

 

 gameWorld.init(); // Initializes all Managers in registration order

 

 // Create entities

 auto player = gameWorld.addGameObject();

 player.add<TransformComponent>(position);

 player.setActive(true);

 

 // Query entities via views

 for (auto [entity, transform, active] : gameWorld.view<

  TransformComponent, Active

 >().whereEnabled()) {

  // Process matching entities

 }
