Hi, try bool FEditorFileUtils::SaveLevelAs(ULevel ,&FString )

thanks for Your Answerm, I am still not there, Not sure what I am doing wrong…

Header:

UFUNCTION(BlueprintCallable, meta = (DisplayName = “Create Empty World Level”, Keywords = “Word Stream Level”), Category = " Functions")
static void createLevelR(FString &FileName, FName WorldName);

CPP:

void UInsaneFunctionLib::createLevelR(FString &FileName, FName WorldName)
{
UWorld* myWorld = UWorld::CreateWorld(EWorldType::Editor, false, WorldName, nullptr, true);
bool temp = FEditorFileUtils::SaveLevelAs( myWorld->PersistentLevel , &FileName);
}

Error:

void UInsaneFunctionLib::createLevelR(FString &FileName, FName WorldName)
{
UWorld* myWorld = UWorld::CreateWorld(EWorldType::Editor, false, WorldName, nullptr, true);
bool temp = FEditorFileUtils::SaveLevelAs( myWorld->PersistentLevel , &FileName);
}

Now Error:

It seems compiler doesn’t know where is SaveLeveAs function implementation, try including FileHelpers.h.

6

I did, I also tried to add to plugin Module. but than it says that such header does not exist…

7

here they say it’s abug:

8

but they made it work somehow :confused:

As that post says try copying SaveLevelAs code into your function or call it without a filename.

So I tried to include this : #include “Editor/UnrealEd/Public/FileHelpers.h” and #include “FileHelpers.h” in the cpp file.

I also tried without “FileName” but it’s all the time the same Error “LNK2018”
