File Listing

The file content with the documentation metadata removed is:

 # helios::engine::modules::ui::transform::systems

 

 UI positioning systems.

 

 This namespace contains systems that compute screen positions for UI elements based on their transform components and current viewport dimensions.

 

 ## Systems

 

 | System | Description |

 |--------|-------------|

 | `UiTransformSystem` | Computes screen positions based on anchor, pivot, offsets, and viewport bounds |

 

 ## Processing

 

 `UiTransformSystem` queries entities with:

 - `UiTransformComponent` - positioning parameters

 - `TranslationStateComponent` - output position

 - `ComposeTransformComponent` - transform composition

 - `ModelAabbComponent` - element bounds for pivot calculations

 

 The system updates `TranslationStateComponent` based on the current viewport snapshot dimensions.

 @brief UI positioning systems.

 @details Contains systems that process UI transform components to compute final screen positions. The UiTransformSystem reads viewport snapshots and applies anchor/pivot/margin calculations.
