EngineRoleTag

template <typename TMemberHandle>

using helios::engine::scene::systems::WorldBoundsUpdateSystem< TMemberHandle >::EngineRoleTag = SystemRole

Runtime role tag used for system registration.

Public Member Functions

update()

template <typename TMemberHandle>

void helios::engine::scene::systems::WorldBoundsUpdateSystem< TMemberHandle >::update (UpdateContext & updateContext)

inline noexcept

Executes one update pass over active bounds tuples.

For each active entity, world-space bounds are recomputed only when the world transform component is marked dirty.

Parameters

updateContext

Frame-local update context with ECS access.
