Member Function Documentation

GetDefinitions()

TArray< FActorDefinition > AStaticMeshFactory::GetDefinitions ( )

finalprivatevirtual

Retrieve the definitions of the static mesh actor.

Reimplemented from ACarlaActorFactory.

Definition at line 15 of file StaticMeshFactory.cpp.

References Float, and String.

ReleaseContentPack()

void AStaticMeshFactory::ReleaseContentPack ( const FString &  MountPoint )

overrideprivatevirtual

Drop every cached definition, parameter and loaded asset that refers to content under MountPoint ("/<Pack>/"), so a content pack can be unmounted; the dropped blueprints are gone until the next episode.

Reimplemented from ACarlaActorFactory.

Definition at line 38 of file StaticMeshFactory.cpp.

References MeshCacheByPath.

SpawnActor()

FActorSpawnResult AStaticMeshFactory::SpawnActor ( const FTransform &  SpawnAtTransform, const FActorDescription &  ActorDescription  )

finalprivatevirtual

Spawn an actor based on ActorDescription and Transform.

Precondition

ActorDescription is expected to be derived from one of the definitions retrieved with GetDefinitions.

Reimplemented from ACarlaActorFactory.

Definition at line 49 of file StaticMeshFactory.cpp.

Member Data Documentation

MeshCacheByPath

TMap<FString, TObjectPtr<UStaticMesh> > AStaticMeshFactory::MeshCacheByPath

private

Lazy, memoizing mesh cache keyed by mesh path.

This factory takes an arbitrary mesh path at spawn time (there is no catalog to pre-populate from), so the cache fills on first spawn of a given path and spares subsequent spawns of the same path the synchronous LoadObject hit.

Definition at line 36 of file StaticMeshFactory.h.
