动态加载流关卡

UWorld* PersistentWorld = GetWorld();

if (!PersistentWorld)

{

    UE_LOG(LogTemp, Fatal, TEXT("UDynamicLevels::LoadTileToStreamingArray >> Invalid PersistentWorld!!!"));

    return;

}

//new StreamingClass Instance 新流关卡实例

UClass* StreamingClass = ULevelStreamingKismet::StaticClass();

ULevelStreaming* StreamingLevel = Cast<ULevelStreaming>(StaticConstructObject(StreamingClass, PersistentWorld, NAME_None, RF_Transient, NULL));

// FName PackageName = TEXT("/Game/TempUmap/Level_01") 根据项目实际情况获取并设置PackageName

StreamingLevel->SetWorldAssetByPackageName(PackageName);

//Make New Level Visible 使流关卡可见

StreamingLevel->bShouldBeLoaded = true;

StreamingLevel->bShouldBeVisible = true;

StreamingLevel->bShouldBlockOnLoad = false;

//Very Important, used by LevelStreaming* to load the map 设置流关卡的包名

StreamingLevel->PackageNameToLoad = PackageName;

//Add to UWorld 将流关卡添加到World中

PersistentWorld->StreamingLevels.Add(StreamingLevel);
