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"

calling function from TScriptInterface that is implemented in blueprints

Hi, I have a

UPROPERTY()
TScriptInterface<.SomeInterfaceClass> MyInterface;

now I can assign the property in editor and I would like to be able to call the SomeInterfaceClass functions from this property.
Interfaces that are purely implemented in blueprints and have the 'bImplementedByK2 == true' have the Interface part of the TScriptInterface set to NULL. How should I call my interface functions in this case?

Thanks in advance,
Marek

I found a solution. It's way easier than I expected :) In case anybody encounters same problem I'll post it here.

Whenever you create and implement an interface by using the GENERATED_UINTERFACE_BODY() and GENERATED_IINTERFACE_BODY() it fills all your UFUNCTION() functions in ProjectName.generated.cpp and gives them a static Execute_FunctionName( UObject* O, Params... ); equivalent where you just pass the UObject* O as the function context.

Cheers
