 # helios::engine::modules::physics

 

 Physics simulation and collision detection subsystem for the game engine.

 

 This namespace provides the complete physics layer for the helios game engine, including movement simulation, collision detection, and physics-related event handling.

 

 ## Submodules

 

 | Submodule | Purpose |

 |-----------|---------|

 | `collision/` | AABB collision detection with spatial partitioning |

 | `motion/` | Velocity-based movement and steering systems |

 

 ## Key Classes

 

 ### Collision

 

 | Class | Purpose |

 |-------|---------|

 | `CollisionComponent` | Layer ID, collision mask, and behavior per collider |

 | `AabbColliderComponent` | World-space AABB for broad-phase detection |

 | `CollisionStateComponent` | Per-frame collision results (solid/trigger hits) |

 | `GridCollisionDetectionSystem` | Spatial-hash broad-phase + narrow-phase collision |

 | `BoundsUpdateSystem` | Updates world-space AABBs from transforms |

 | `CollisionStateResponseSystem` | Executes collision behaviors (despawn, bounce) |

 

 ### Motion

 

 | Class | Purpose |

 |-------|---------|

 | `Move2DComponent` | Velocity, speed, acceleration, damping config |

 | `DirectionComponent` | Normalized direction vector |

 | `SteeringComponent` | Rotation speed and steering behavior config |

 | `Move2DSystem` | Integrates velocity and updates translation |

 | `SteeringSystem` | Updates heading from steering input |

 @namespace helios::engine::modules::physics

 @brief Physics simulation and collision detection subsystem for the game engine.

 @details This namespace provides the complete physics layer for the helios game engine, including movement simulation, collision detection, and physics-related event handling. The architecture follows a data-driven design where components store state and systems process behavior.
