【UE4 C++】关卡切换、流关卡加载卸载

切换关卡

基于 UGameplayStatics::

• OenLevel

  UGameplayStatics::OpenLevel(GetWorld(), TEXT("NewMap"));
  

• OpenLevelBySoftObjectPtr

  FSoftObjectPath NewMapPath(TEXT("World'/Game/CPPFunction/Interface/NewMap.NewMap'"));
  TSoftObjectPtr<UWorld> NewMap(NewMapPath);
  UGameplayStatics::OpenLevelBySoftObjectPtr(GetWorld(), NewMap);
  

获取当前关卡名

• GetCurrentLevelName

  UKismetSystemLibrary::PrintString(GetWorld(), UGameplayStatics::GetCurrentLevelName(GetWorld()));

基于 UGameplayStatics::

加载

• UGameplayStatics::LadStreamLevel

  static void LoadStreamLevel(const UObject* WorldContextObject, FName LevelName, bool bMakeVisibleAfterLoad, bool bShouldBlockOnLoad, FLatentActionInfo LatentInfo);
  

• UGameplayStatics::LoadStreamLevelBySoftObjectPtr

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

卸载

• 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);
  

获取流关卡

• GetStreamingLevel

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