 # helios::engine::modules::physics::collision::components

 

 Collider components for collision detection.

 

 This namespace contains data components that define entity collision properties used by the physics and collision detection systems.

 

 ## Components

 

 | Component | Description |

 |-----------|-------------|

 | `AabbColliderComponent` | Axis-Aligned Bounding Box for broad-phase collision detection. |

 | `CollisionComponent` | Layer membership and collision masks (trigger/solid). |

 | `CollisionStateComponent` | Per-frame collision state written by detection systems. |

 

 ## Usage

 

 Attach `AabbColliderComponent` to define spatial bounds and `CollisionComponent` to specify layer-based filtering. After collision detection runs, query `CollisionStateComponent` to read collision results for the current frame.

 

 ```cpp

 auto& collider = gameObject.add<AabbColliderComponent>();

 collider.setBounds(helios::math::aabbf{{-0.5f, -0.5f, -0.5f}, {0.5f, 0.5f, 0.5f}});

 

 constexpr uint32_t LAYER_PLAYER = 1 << 0;

 constexpr uint32_t LAYER_ENEMY = 1 << 1;

 constexpr uint32_t LAYER_POWER_UP = 1 << 2;

 

 auto& collision = gameObject.add<CollisionComponent>(LAYER_PLAYER);

 collision.setTriggerCollisionMask(LAYER_ENEMY | LAYER_POWER_UP);

 ```
