Systems​

SystemDescription
UiTransformSystemComputes screen positions based on anchor, pivot, offsets, and viewport bounds

Processing​

UiTransformSystem queries entities with:

  • UiTransformComponent - positioning parameters

  • ComposeTransformComponent - transform composition
  • ModelAabbComponent - element bounds for pivot calculations

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