• UGameplayStatics::LoadStreamLevelBySoftObjectPtr

  static void LoadStreamLevelBySoftObjectPtr(const UObject* WorldContextObject, const TSoftObjectPtr<UWorld> Level, bool bMakeVisibleAfterLoad, bool bShouldBlockOnLoad, FLatentActionInfo LatentInfo);
  

卸載

• UnloadStreamLevel

  static void UnloadStreamLevel(const UObject* WorldContextObject, FName LevelName, FLatentActionInfo LatentInfo, bool bShouldBlockOnUnload);
  

• UnloadStreamLevelBySoftObjectPtr

  static void UnloadStreamLevelBySoftObjectPtr(const UObject* WorldContextObject, const TSoftObjectPtr<UWorld> Level, FLatentActionInfo LatentInfo, bool bShouldBlockOnUnload);
  

獲取流關卡

• GetStreamingLevel

  static class ULevelStreaming* GetStreamingLevel(const UObject* WorldContextObject, FName PackageName);
