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"

_Implementation and _Validate (4.9.2)

Are the _Implementation and _Validate definitions required in the header file when using server functions? I honestly can't tell if there is a different using them or not using them, when it it comes to replicating.

The forums and other answers have a handful of answers for previous versions of the engine with some included information regarded GENERATED_BODY( ) and GENERATED_UCLASS_BODY( ) but I am still a bit confused on the whole thing.

I have found out that _Implementation and _Validate are required in the .h file, using using 4.9+ as GENERATED_UCLASS_BODY( ) is depreciated.

As an example, this would be a server function in a .h file:

 UFUNCTION( Server, Reliable, WithValidation )
 void ServerMyFunction( );
 void ServerMyFunction_Implementation( );
 bool ServerMyFunction_Validate( );

And this would be the .cpp:

 void AMyClass::ServerMyFunction_Implementation( )
     // Code that would be run on the server after validation
 bool ServerMyFunction_Validate( )
  return true;

And when using this server function, call:

 ServerMyFunction( );


 AMyClassReference->ServerMyFunction( );
