定义 UserData

cpp 复制代码

UCLASS()
class ADVMOD_API UStaticMeshUserData : public UAssetUserData
{
	GENERATED_BODY()
	
public:
	UPROPERTY(EditAnywhere)
	FString MeshPath;
};

新建，添加

cpp 复制代码

UStaticMeshUserData* StaticMeshUserData = StaticMesh->GetAssetUserData<UStaticMeshUserData>();
if (!StaticMeshUserData)
{
	StaticMeshUserData = NewObject<UStaticMeshUserData>(StaticMesh, UStaticMeshUserData::StaticClass(), NAME_None, RF_Transactional);
	StaticMeshUserData->MeshPath = StaticMesh->GetPathName();
	StaticMeshUserData->PostEditChange();

	StaticMesh->AddAssetUserData(StaticMeshUserData);
	StaticMesh->PostEditChange();
	StaticMesh->MarkPackageDirty();
}

获取

cpp 复制代码

UAssetUserData* Data = Obj->GetAssetUserDataOfClass(UStaticMeshUserData::StaticClass());
UStaticMeshUserData* UserData = Cast<UStaticMeshUserData>(Data);
// 或
UStaticMeshUserData* StaticMeshUserData = StaticMesh->GetAssetUserData<UStaticMeshUserData>();
