FMassCommandBuildEntity | Unreal Engine 5.8 Documentation

API > API/Runtime > API/Runtime/MassEntity

Builds reserved entities with fragment values (and optionally tags). Entities must be pre-reserved via EntityManager->ReserveEntity(). Uses PushCommand for cross-chunk batching.

Example: FMassEntityHandle Entity = EntityManager->ReserveEntity(); Context.Defer().PushCommand(Entity, FMyFragmentA(42), FMyTag());

Supported types: FMassFragment + FMassTag (including sparse). Breakpoint support: Yes — CheckCreateEntityBreakpoints called at PushCommand time.
