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"

BlueprintNativeEvent in interface automatically overridden

I've created a native interface to expose the generic team system to blueprint. It basically wraps the generic team interface in some stuff that I need in my BP functions. Here is my interface class.

 UINTERFACE()
 class UTeamBPInterface : public UInterface
 {
     GENERATED_UINTERFACE_BODY()
 };
 
 class ITeamBPInterface
 {
     GENERATED_IINTERFACE_BODY()
 
     /** Assigns Team Agent to given TeamID */
     UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category = "Teams")
     void SetSameTeam(const AActor* const Other);
 
     /** Determines if these two are on the same team */
     UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category = "Teams")
     bool GetSameTeamAs(const AActor* const Other);
 };

I also have implementations for both these functions which basically wrap the generic team ID stuff.

The problem is when I add the above interface to a BP, the GetSameTeamAs function is automatically overridden in the BP, but the SetSameTeam function is not. I don't want either function to be overridden in the BP, I want them to use the native implementation. Am I doing something wrong, or is this a bug?

I'm curious about this too

In UE 4.21.2, I'm hitting this problem, at least with the GetSameTeamAs (function) version: If I add the interface to a Blueprint, there is immediately an override generated for the BlueprintNativeEvent, with nothing attached to the return value, hiding the _Implementation default behaviour which I have customised. This seems like a bug. >_<

I am curious if the SetSameTeam (event) is getting its _Implementation hidden in the same way or not, as that would point towards whether the issue is specific to functions, or affects events too.

I am also having this issue. I was not having any issues before updating to 4.22, but now I've been trying everything I can and I can not get the default implementation to run...

This isn't a pretty way to fix the issue, but if that function returns a value, then SetSameTeam will show up in the BP. I'm not 100% on exactly why that is...I think it treats functions as "Events" if they don't return a value.
