Description

helios::engine

Main engine module aggregating core infrastructure and game systems.

Overview

This module provides access to the complete helios engine functionality, including the ECS architecture, game systems, messaging infrastructure, and development tooling.

Submodules

Module	Purpose
helios.engine.core	Data structures, messaging re-exports, units
helios.engine.ecs	ECS base classes (GameObject, Component, System) and query system
helios.engine.runtime	Runtime infrastructure (world, gameloop, pooling, messaging, factory)
helios.engine.modules	Domain-specific components and systems (physics, spatial, scene)
helios.engine.mechanics	Gameplay mechanics (bounds, combat, spawn, input)
helios.engine.tooling	Frame pacing and performance metrics

Usage

 import helios.engine;

 

 // Access ECS classes

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

 auto entity = std::make_unique<helios::engine::ecs::GameObject>();

 world.addGameObject(std::move(entity));

 

 // Access game loop - systems are registered with phases/passes

 helios::engine::runtime::gameloop::GameLoop gameLoop;

 gameLoop.phase(PhaseType::Main)

  .addPass()

  .addSystem<Move2DSystem>(&world);

 

 // Access tooling

 helios::engine::tooling::FramePacer pacer;
