Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

#if WITH_EDITOR only removing code from .h, not .cpp

Using #if WITH_EDITOR I have declared a property, that when packaged without the editor, correctly removes itself from the code. However references to that property (also wrapped in #if WITH_EDITOR) get packaged anyway; resulting in compile errors.

Here is the code:

.h

 #if WITH_EDITOR
 
     UPROPERTY(EditAnywhere, Category = "Debug")
     bool DrawDebug = false;
 
 #endif

.cpp

 #if WITH_EDITOR
 
         if (DrawDebug)
         {
             UE_LOG(LogTemp, Warning, TEXT("Why is this being packaged?"));
         }
 
 #endif

Compile error:

 error C2039: 'DrawDebug': is not a member of 'UBTTask_SetOptimalCoverPose'
Product Version: UE 4.19

Hey.

WITH_EDITOR doesn't work with UPROPERTIES/UFUNCTIONS at all (probably same goes for UCLASSes but I haven't tried that). If you want to compile out a UPROPERTY, you can use WITH_EDITORONLY_DATA instead.

Cheers.

Thank you!

WITH_EDITOR appears to work for overriden UFUNCTIONs, like PostEditProperties, but swapping to WITH_EDITORONLY_DATA for everything else has fixed my build errors.
