Unreal Engine 4.20 Released!

[stefan872]

Hi, I have a problem with updating plugin from 4.19 to 4.20 version.

This is 4.19 code:

483: TArray<FString> Streaming;
484: TArray<ULevelStreaming*>& Levels = World->StreamingLevels;
485: for(ULevelStreaming* EachLevel : Levels)
486: {
487: if(!EachLevel) continue;
488:
489: FString NoPIELevelName = UMySaveLibrary::RemoveLevelPIEPrefix(EachLevel->GetWorldAssetPackageName());
490:
491: Streaming.Add(NoPIELevelName + FString("=") + BOOLSTR(EachLevel->IsLevelVisible()));
492: }
493: Ar << Streaming;

Here is the log:

(484): error C2248: 'UWorld::StreamingLevels': cannot access private member declared in class 'UWorld'
H:\Games\Epic Games\UE_4.20\Engine\Source\Runtime\Engine\Classes\Engine/World.h(796): note: see declaration of 'UWorld::StreamingLevels'
H:\Games\Epic Games\UE_4.20\Engine\Intermediate\Build\Win64\UE4Editor\Inc\Engine\LevelStreamingKismet.generated.h(12): note: see declaration of 'UWorld'

I know that in 4.20 version is changed functions for level streaming, but I don't know which one I need to use.

Thanks in advance.

I haven't used that particular variable, but I have other code that accessed ex-public members.
In all my cases I found out Epic replaced the direct access for a getter method. And searching the docs I found one for StreamingLevels as well, that returns exactly the type you declared there, but constant. So just change that line into

const TArray<ULevelStreaming*>& Levels = World->GetStreamingLevels();

and it should work.

Hi.

I encountered the following issue:

When I'm packaging the game for IOS in Shipping from Editor and I have the "Support bitcode in Shipping" option enabled the build fails with the following error:

ld: bitcode bundle could not be generated because '/Users/user/UE4/Builds/SKU1112/D/Engines/UE4/UE_4.20/Engine/Source/ThirdParty/mtlpp/mtlpp-master-7efad47/lib/IOS/libmtlpps.a(command_buffer_fence.o)' was built without full bitcode. All object files and libraries for bitcode must be generated from Xcode Archive or Install build
file '/Users/user/UE4/Builds/SKU1112/D/Engines/UE4/UE_4.20/Engine/Source/ThirdParty/mtlpp/mtlpp-master-7efad47/lib/IOS/libmtlpps.a' for architecture arm64

I'm building on Windows with configured remote Mac. When the bitcode option is disabled everything works fine.

It seems the thirdparty has been built without bitcode support. I'd be nice to get this file to be able to build with the bitcode

This issue seems to exist in 4.21, also.
