Description​

System that updates AABB colliders based on entity transforms.

This system recalculates the world-space AABB for entities by transforming the canonical model AABB through the composed local transform (Translation * Rotation * Scale) and the parent's world transform.

Required components:

  • ModelAabbComponent (source canonical AABB)
  • SceneNodeComponent (for parent world transform)
  • TranslationStateComponent (local translation)
  • ScaleStateComponent (local scaling)
  • RotationStateComponent (local rotation)
  • AabbColliderComponent (receives the updated world-space AABB)

update()​

void helios::engine::modules::physics::collision::systems::BoundsUpdateSystem::update (helios::engine::runtime::world::UpdateContext & updateContext)
 inline noexcept virtual

Updates collider bounds for all applicable entities.

For each entity with the required components, composes the local transform from translation, rotation, and scale, then applies the parent world transform to compute the final world-space AABB.

Parameters
updateContext

Context containing deltaTime and other frame data.
