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"

Generic parameter in DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam?

I've been scratching my head for hours on how to convert this C# code to C++:

 public delegate void Delegate<T>(T DelegateParam) where T : MyClass;

I've tried a lot, but all failed. Here's my current implementation that doesn't work (I forgot about the other tries that I've done due to frustration):

 template<UMyClass* T>
 DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FDelegateName, T, DelegateParam);
Product Version: UE 4.14

Hi,

You can't create delegate templates. You could create a TFunction template:

 template <typename T>
 using TDelegateName = TFunction<void(T*)>;

... but as these are not exposed to UE reflection as dynamic delegates are, this is probably not what you want.
