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"

[C++ Compiler Warning Feature Request] Throw a warning if a Blueprint Library function is not marked as static ♥ Rama

Dear Epic,

When I am adding functions to my C++ Blueprint Libraries (such as my Victory Plugin)

I frequently forget to mark it as static.

 UFUNCTION(BlueprintCallable,Category="Brain Codes Library")
 void BCEditorHighlighting_HighlightReceivers();

~ Load the editor

~ Can't find it, and realize omg, I forgot to mark it as static

~ Close editor, recompile

 UFUNCTION(BlueprintCallable,Category="Brain Codes Library")
 static void BCEditorHighlighting_HighlightReceivers();

While this is entirely my fault it, it does necessitate a complete .h recompile and shutdown/reload cycle of the editor which is a rather long cycle because my C++ code base has grown quite large.

It would be lovely if you could consider throwing a compile warning if a UFUNCTION that is in a UBlueprintFunctionLibrary is not marked as static, given that it is part of the class comment itself:

 // This class is a base class for any function libraries exposed to blueprints.
 // Methods in subclasses are expected to be static, and no methods should be added to this base class.
 UCLASS(Abstract, MinimalAPI)
 class UBlueprintFunctionLibrary : public UObject

Again, this is entirely my own user error, but I am trying to help you make UE4 C++ ever more awesome and this little feature would really help me out personally

Thank youuuuu

would it be possible for the UHT to automatically insert the missing Static keywords when parsing static function libraries?

I don't think UHT should interfere in code, you should be able to do what compiler let you do, warning would be satisfactory.

I'm with Shadowriver on this one. Coders need to be responsible for their code. Still a warning would be nice +1.
